Flirting Sex Train: Chapter 1 - About the Women-Only Car

 He had completely overslept.

He really should have gone to sleep after he used up almost all his materials to complete an event in the mobile game he was hooked on.

Unfortunately, he had felt wide awake from excitement and ended up grabbing one of the unread light novels piled up in his room. It had been so engaging he had read it all the way through and then noticed the beginnings of dawn creeping in through the window and the chirping of sparrows.

Drowsiness had rapidly hit him and when he woke up it was 10 minutes past when he usually left the house.

He had been late a lot recently and his homeroom teacher had insisted he be on time today and even threatened to give him a ton of extra homework as a penalty.

“I’m screwed if I’m late again, but I might just make it if I hurry!”

That Monday morning, Ousumi Youta threw on his uniform and dashed to the train station.

He got through the ticket gate just as the train pulled into the station.

(I can definitely make it if I get on this rapid train!!)

With a train that stopped at each station, he might still make it if he ran full speed to school, but he had already used up all his strength getting here from home. This rapid train was his only hope.

“Wait, don’t leave yet! Nooooo!”

He drew out every last ounce of strength to run to the platform and dive into the closing doors.

“Phew, I made it.”

He leaned forward and rested his hands on his knees while catching his breath.

That was when an unusually sweet and pleasant aroma reached his nose.

(Hm? What’s this?)

He looked up to find only women and they were all giving him curious looks.

(Fuck! Is this a women-only car!?)

He paled.

He had boarded the last car because it was closest to the ticket gate.

He normally made sure he used one of the normal cars, but he had been in such a hurry.

(Sh-shit, what do I do?)

They could easily think he was some kind of pervert.

They might even assume he was trying to molest them and throw him to the police. If that happened, his life was over.

(Should I get off at the next station and change cars? Oh, wait. The next station is the one I want anyway.)

The rapid train skipped a lot of stations, so it would not be stopping for a while.

“Oh, a new face. Looks like he’s from Tourin Academy.”

“Did he get on here by accident?”

“What should we do?”

While he panicked and froze, a group of girls looked at him and whispered to each other. They appeared to have worked out his school from his uniform.

They might hand him over to a station worker at the next stop and claim he was a molester.

(I need to cut through to a normal car!!)

He kept his hands overhead to show he had no intention of touching anyone and checked how crowded the car was to see if he could walk through without brushing up against anyone.

“Wha-!?”

But what he saw there was truly unbelievable.

“Ah, ahh …”

“Keh heh heh. Just look how wet you are.”

“Ah, ahhh, look everyone. This man is molesting me! Ah, ahhh!! Oh, god! It’s so thick!”

“You’re the one wearing what barely qualifies as clothing. How could I resist?”

Several men were on the women-only car and they were blatantly molesting some of the women.

But not only were the other women pretending not to notice what was happening, they were partially slipping their clothing off to attract the men to them.

“Eh? What? Aren’t you going to stop them?”

Youta stared in shock and the whispering girls quickly surrounded him.

“Whoa! S-sorry, I forgot to check which car I was getting on!! I wasn’t trying to do anything and I’ll get off at the next station. B-but why isn’t anyone saying anything about, uh, what’s happening over there!?”

While he panicked and stammered, the girls started rubbing their bodies against him.

“Oh, he really did get on by accident.”

“He looked like a proper virgin boy, so I bet he hadn’t even heard the rumors.”

“But he got on the car, so the rules apply to him, right?♪”

“Eh? Eh!? Wh-what!? Ah, w-wait, y-you’re touching me. I’m serious!!”

He sensed danger from the faint sweet aroma in his nose and from the soft breasts and thighs pressed against him.

(Oh, no! We’re touching. They’ll say I molested them. They’ll throw me to the police.)

“Oh, how cute. He’s scared.”

“It really makes you want to grope them when they’re this scared, doesn’t it?)

(They’re trying to set me up, aren’t they!? Ahh, I’m innocent. I swear I’m innocent!!)

He was sure they were going to have him do something sexual and get a photo or something. While one of them guided his hand up her skirt, the other girls reached out to touch his butt and crotch.

“H-help me!”

His desperate attempts to reject it and escape only excited the girls more.

“Got you♪”

“Hyaaah!”

One girl hugged him from behind and distracted him with the soft mounds pressing against his back while another girl moved her lips in toward his.

“Ahhh!!”

There was nothing for him to do and he tensed up, but a tall girl with chestnut hair used her hand to block the lips about to touch him.

“Not so fast. I hate to interrupt your fun, but this boy is here for us. It’s his first time on the car, so he’s a little confused is all.”

“Heh heh. Sorry about the confusion.”

Another girl, this one short with blonde twintails and an innocent face, tugged on his hand to remove him from the girl holding him from behind. A more proper-looking girl with a black braid stood next to those two with flushed cheeks and an awkward look on her face.

The three of them wore a pink blazer, a dark purple dirndl, and a short strawberry checked miniskirt, so he could tell they were from St. Lucio Academy two stations away from his own school.

It was a high-class girl’s school and the boys from nearby schools saw it as a sort of paradise. Those three carried themselves in a different way from the other girls, their unique beautiful faces showed off three distinct types of charm, and the girls trying to set him up as a molester were overwhelmed and backed down.

“O-oh? He’s a little plain, but he’s not bad looking, so I just thought he might make a good partner is all. But if you’ve got a reservation, then that’s that.”

They tried to laugh it off as they reluctantly left.

“Sigh. Thanks, you saved me. They were going to make me look like a molester or something.”

If the cops had been called, his life would have been over, so he breathed a sigh of relief and thanked them for saving him, but they were all staring at his face.

“But what is with this train!? Why isn’t anyone saying anything about what’s happening over there!?”

He felt bad for getting on the women-only car, but the sex acts happening all around him seemed out of place.

His confused question elicited a snicker from the lively-looking girl with long chestnut hair and drooping facial features.

“You really did get on by accident, didn’t you?” said the short girl with blonde twintails, a youthful face, and a doll-like cuteness while she approached him. “But maybe this is what they call fate.”

“Ahh.”

She was short and slender, but her chest was very large. When he looked down at her, it was impossible not to see those mounds.

“Yes, yes. This would be our lucky chance, wouldn’t it?”

The long chestnut-haired girl moved in close enough for him to feel her breath. Her chest was not as large as the short girl’s, but the beautiful bowl-shape of the mounds was visible through her blazer and they were right in front of his face since she was taller than him.

(Wh-what is it now?)

He thought he had escaped being wrongfully accused, but now the girls who had saved him were approaching him in much the same way.

“Seeing you up close, that girl was right. You’re plain but not bad looking. And you seem innocent enough, so I think I’m down for it.”

“Yeah, yeah. I know I am♪”

The two stared at him as if appraising him and then exchanged an approving nod.

(Wh-what? Why are they staring at my face? Have we met somewhere before? No, we couldn’t have.)

They did not seem interested in framing him for molestation. He was utterly confused by what they were talking about, but then the shy-looking third girl hesitantly spoke to the other two.

“Let’s not do this, Erisa-chan, Yuzu-chan. I don’t like this kind of thing. And…”

With her long black hair worn in a braid, her gentle and elegant features, and her graceful demeanor, she seemed like the quintessential student of a high-class girl’s school. However, the overwhelming presence of the mounds on her chest kept his eyes glued to that volume that far surpassed the other two.

“C’mon, Suzuri. Live a little. He came running to you, so you couldn’t ask for a more perfect chance!”

“That’s right, Suzuri-chan. Keep this up and you’ll grow up to be some wrinkly old virgin who’s never held hands with a boy, not to mention fucked one.”

“Ahhh.”

She blushed at the indecent language coming from the twintailed girl named Yuzu.

(These two are good looking, but that one’s super cute. And she’s got a hell of a rack.)

He was still confused, but his male instincts meant he could not help but stare at some things when surrounded by good-looking girls with such amazing bodies.

While drawn to the shyness of the one named Suzuri, his gaze focused in on the overwhelming size of her chest.

“And look, I think he has a thing for your tits, Suzuri,” said the girl named Erisa.

“Kyah!”

“Oh, sorry!! I wasn’t trying to, um, look at, uh…”

When the gentle girl blushed brighter and hid those mounds behind her hands, he blushed and quickly looked the other way.

“Is this not an ordinary women-only car? What are you planning to do with me?”

He took a stronger tone to hide his embarrassment and asked Erisa about the abnormal situation.

“This is a women-only car where people in the know gather to enjoy some molester roleplaying or other sex. We call it the sex-only car. Does that answer your question, Tourin Academy Class 1-A Student Number 5, Ousumi Youta-kun?”

“A sex-only car!? And how the hell do you know my name!? Whoa!”

He was shocked by that dirty-sounding name and her overly-specific knowledge of his identity, but then Erisa and Yuzu grabbed him from either side.

“We know all about you. Because we asked some of the students from your school.”

“But why!? Ahh!”

Instead of answering him, Yuzu untucked his shirt and slipped her hand below. Her warm palm rubbed up from his stomach to his chest and he could not help but cry out.

“I don’t know when it started either, but men and women interested in living out their molestation fantasies or just having sex during their commute gather on the last car of this rapid train so they can have fun without worrying. We learned about it not too long ago and we’re completely hooked. Ha ha♪”

Erisa did not seem interested in explaining why they had been investigating him either, so she instead explained about this strange world where sex on the train was allowed.

“Whoa, wh-where do you think you’re touching me!? Y-you can’t do that! Ahh!!”

Since Yuzu was already working at his chest, Erisa slid her hand down from his stomach and reached his crotch.

“Oh, you’re already nice and hard. Hm, and you’re packing a pretty big one, too.”

Seeing the sexual acts occurring in the car and having these busty girls approaching him had made his dick fully erect, so she had no trouble grabbing it through his pants.

“H-hey, stop that. A girl shouldn’t just grab that! Ahhhh!”

He knew it was no more than a selfish male desire, but he wanted girls to be a little purer than this.

But Erisa’s breathing grew heavy with arousal as she slowly stroked the thick, hard erection she could feel in her hand.

“Khh! Ah, ahhh…shit, that’s so good.”

His erect shaft felt a throbbing pleasure several times greater than what he felt while jerking off.

He knew he had to get her to stop, but his body wanted it to continue and kept him from doing anything.

(Wait, am I the one being molested here? By girls as hot as this!?)

Plus, women-only cars had been created so women could avoid molesters, but the women boarding this one were giving their consent to that very thing.

That alone would have been a shock, but these girls he had never before met were also teasing his most embarrassing body part. The absurdity of it all filled him with an arousal that kept him from thinking straight.

“His nipples are getting hard too,” said Yuzu. “You’re such a sensitive boy, Youta-kun.”

“Wait, that tickles, khh! Ahhh!!”

The short girl’s fingertips rolled around the swollen and throbbing tips until a strange tingling rose up within the ticklish feeling and sapped his body of strength.

His reaction placed a seductive look on her innocent face to show her growing desire. Her voice shook and her breaths grew heated while her small hand worked at his nipples even harder.

“Yes, the more I stroke it, the harder and bigger it gets. Dicks are the best toys. That’s right, Youta, your dick is no more than my toy♪”

Erisa’s stroking of his penis through his pants intensified and she applied the perfect amount of pressure to his hard flesh. She let the maddeningly sweet sensation grow just enough to make him want something stronger while he felt a hot urge rising from within.

“Ahh, Youta-kun, you can touch my body too,” said Yuzu. “This is the sex-only train, so you can touch me all you like.”

The two of them pressed their breasts against his upper arms and tangled their legs around him to press their crotches against his thighs.

(Whoa, that’s their tits!! H-holy shit! They’re both big, but I can still tell a difference in size and feel. Erisa’s are so squishy and seem to push back at me, but Yuzu’s are so soft and my arm seems to sink into them forever. They’re both so fucking good!!)

He was not touching them directly, but he could still tell this was the sensation he had long dreamed of.

(And their crotches…their pussies are rubbing against my legs. Wait, is that a wet sound I hear? Does that mean they’re wet?)

They were still clothed, so he had no idea what was going on in there.

(I’m allowed to strip them on this train, right? I want to see how wet their pussies are and how their tits feel directly.)

But he was a virgin and his lack of experience kept him from taking that step.

(I want to touch them too. But…)

“Ah, ahhh. Your chest is so manly, but your nipples are hard. Nh, ah, ahhhh.”

“Y-your dick is quite something too. Ahh.”

They stroked his penis and teased his nipples while pressing their chests and rubbing their crotches against him. Their breaths grew heavier and more heated.

“Kh, ahh. If you keep this up, I won’t be able to stop myself. I’ll go crazy…and start touching you, even though we’re on a train.”

He had never had any luck with girls, but now three good-looking girls from a high-class girl’s school were giving him a sweet caress.

His lack of experience left him without the courage to touch them back and he simply writhed from the pent-up arousal, but Yuzu and Erisa whispered to him once they caught on.

“Go ahead and touch Suzuri-chan. She’s feeling just as horny as you are, right now. Ah, ah, ahhh.”

“She’s just as shy as you are, so she can’t bring herself to make the first move. But believe me when I tell you she’s just as interested in sex as us, so you need to work up the courage for her.”

He could barely think after the lack of sleep and this unexpected sexual situation, so their request easily swayed him.

“Th-thanks, but I think I’m good.”

Suzuri backed away apprehensively, but she could not take her eyes off of him as he moaned from the sexual stimuli from the other two girls.

That bashful move made his heart pound more than an active pursuit would have.

“Suzuri…-chan.”

Driven by extreme arousal, he reached his hands out toward the shy girl, grabbed her extra-large breasts, and lifted her skirt to slip his fingers to her crotch.

“Hyahn! Ahh, wait!!”

His fingertips sank into the large mound before he could even try to squeeze.

His other hand’s fingertips were soaked by the stickiness leaking from her panties and a seductively wet sound reached his ears.

(Th-this is a girl’s tit! Shit, how can it be so soft? I’m groping this cute-as-hell girl’s giant tit!!)

He had never been popular and he had only ever been able to imagine what a boob would feel like, but now one was right there in his hand.

He trembled with emotion and lost himself in moving his fingers.

(Wow, it squishes so much in my fingers. And that squished shape is kind of hot. But when I let go, it pushes back on my fingers and returns to its normal shape.)

“Nhh, I…”

As his groping picked up speed, Suzuri wrinkled her brow and quietly cried out.

(W-was that a moan!? Is she enjoying this?)

Her faint reaction fired up his arousal even more and a dull throbbing filled his penis.

“Ha ha. Your dick is twitching. You really like Suzuri’s big boobs, don’t you? Here, I’ll stroke it even more.”

“Your heart is pounding like crazy. And your nipples are all sweaty.”

“Kh, but…ahh!!”

The other two girls worked even hard to tease his sensitive parts.

(It isn’t just me. This girl is wet from having her tit groped.)

He could feel the shy-looking girl’s body trembling and her crotch growing wetter as he continued teasing her breasts.

(Oh, I can feel the slit here. It’s getting softer and opening up. When I push in, her panties move up in there. Where’s the hole, I wonder. She just keeps getting wetter. It’s fucking incredible.)

Suzuri’s breathing gradually grew sexier and heavier.

While massaging her breasts, he focused on tactilely searching that unknown place between her legs from over her underwear.

He wanted to give her even more pleasure and see how she responded, so his breathing grew heavier and he stared with bloodshot eyes, but…

“P-please…stop. I…don’t want to do this.”

Her eyes grew visibly damp and tears began spilling from them.

Her complaint made through suppressed moans snapped the horny boy’s mind back in focus.

“Oh! S-sorry! I thought…”

He had let the pleasure get the better of him and done something terrible.

He immediately let go of her chest and crotch and he backed away.

“Oh, dear. Maybe this was a little too sudden for her.”

“There, there. That must have been scary, but we won’t force you to do anything more, so it’s okay.”

Suzuri’s two friends worked to calm her down while she continued to cry with shoulders shaking.

Youta watched it in a daze and had no idea how he was supposed to apologize, but then then train arrived at his stop.

“Hey, sorry about scaring you like that. It looks like this girl wasn’t as ready as we thought she was. See you after school if you want.”

“See you later. Bye, bye.”

“Eh? Um, I…”

He had been driven on by those two’s actions, but since he was still the one who had done the things that actually made Suzuri cry, he felt responsible.

He felt certain they were going to blame him too, but Erisa and Yuzu smiled bitterly and returned to calming Suzuri while he left the train.

“Wh-what the hell was that?”

He was running late, but he stood motionless on the platform for a while after the train left.

He ultimately did have to make a mad dash for school, but he managed to arrive just barely on time.

Unfortunately, he could not pay attention in class after that crazy experience in the train.

(I can’t believe that sex-only car actually exists. And what was that she said? ‘See you after school’? Does that mean what I think it does?)

He turned down his friends’ invitation to stop by the arcade on the way home and stood all alone on the train platform. He watched a few normal trains arrive before the rapid train pulled up.

“That Erisa girl said it was only the rapid train.”

Did this one have an insane sex-only car too? If not, he would be labeled a pervert.

He pretended to just be walking by and hesitantly peeked inside the open door of the women-only car in the very back.

“Whoa!”

A hand suddenly reached out and dragged him inside.

“Ha ha. You actually showed up. I’m glad.”

Inside the somewhat crowded car, a lively-looking girl with long chestnut hair put on a mischievous smile as she pressed her chest against his arm and leaned against him.

She seemed to be alone this time. The short girl with blonde twintails and the shy-looking girl he had made cry were not with her, so he breathed a sigh of relief.

“Um, Erisa-san…was it?”

“Oh, that’s right. We never introduced ourselves. I’m Souga Erisa from St. Lucio Academy Class 1-1. Nice to meet you.”

“Souga…Erisa-san.”

“We’re in the same year, so you can drop the honorific. Anyway, the short twintail girl with me this morning is Houmai Yuzu and the more well-behaved one is Miyazae Suzuri.”

“Houmai Yuzu…and that proper girl is…Miyazae…Suzuri.”

He pictured that casual young twintail girl and the girl who had cried when he touched her, so he hung his head with guilt.

“Oh, don’t worry about what happened. No one will blame you for what happened. This car exists for doing that kind of stuff and you stopped as soon as she said to, so you’re good.”

He could already spot indecent sights all over the car. He could hear seductive moans and smell sweet sexual scents.

“B-but…”

It still pained him to have made her cry.

“She’s always been shy and gets especially nervous around boys, so it was looking like she would never get a boyfriend. We brought her to this car thinking a good hard fucking would solve all that.”

He was fairly certain that would not have worked as planned.

“And when you happened to arrive, it seemed like the perfect chance.”

“Me? But why?”

He recalled that they had already known his full name, his school, his class, and even his student number.

“Suzuri happened to see you giving up your seat to some old person on the way to school and she’s been watching you on the train every morning since, so Yuzu and I decided to do some research.”

“She’s been w-watching me!?”

He could not even remember when he had given up his seat to an old person, so this must have been going on for a while. He was also shocked something so trivial had triggered this, but it was a confusing and happy kind of surprise.

“We thought she was sure to love it if it was with you. We sure didn’t expect her to cry. But again, it wasn’t your fault, so don’t let it bother you. And she’s just shy and a bit of a crybaby, so don’t hold it against her either.”

“I would never! B-but…”

(If she was interested in me because she saw me do something nice, then I really fucked that one up.)

It had been through her clothes, but he had suddenly grabbed her boobs and fingered her crotch. Of course she would be disillusioned.

He had gotten the interest of an elegant and good-looking girl with a huge rack, but he had killed any affection she had for him on their first actual meeting. His head slumped sadly. But at the same time…

“By the way, what do you think you’re doing, Erisa-san!?”

The chestnut girl pressed even closer against him and started rubbing his penis through his pants as if picking up where she had left off that morning.

“Something sexual, of course. This is the sex-only car and we’re two teenagers bubbling over with desire. What else would we do?♪”

“B-be that as it may, we only just met and barely know each other.”

No matter what he said, the pleasant sensation of her weighty breasts and slender body were enough for his dick to rapidly grow.

Erisa gasped with arousal and held his erection tight before rhythmically stroking it through his pants and pressing her breasts against his chest hard enough to squish them.

“Hm, you’re a straitlaced kind of guy, huh? I bet that’s what Suzuri likes about you.”

“But I really think a cute girl like you shouldn’t take this so lightly. You shouldn’t be going to an orgy train to have sex with strangers like me. You need to take better care of yourself!”

He could not physically reject her advances while surrounded by the sexual atmosphere of the train and with precum flowing from his penis as she stroked it. Still, he tried to convince her.

“You think I’m cute?”

She had to hear that a lot, but it still made her eyes shine happily.

All three of those girls were good-looking, but she in particular had an elegant charm that drew the eye.

Her strong-willed face grew visibly flushed with excitement.

“I don’t mean to brag, but I get complimented for my looks a lot. But I tend to be fairly blunt, so Yuzu and Suzuri are the only ones who’ve ever called me cute. You’re the first boy to call me that.”

“R-really? I find that hard to believe. But anyway, could you let go of me?”

Her stroking hand only picked up speed and a tingling sensation ran through his throbbing erection.

“I thought it was already fully hard when I grabbed it, but it just keeps getting bigger as I tease it. Let’s see how big this bad boy can get.”

She seemed very interested in his still-growing erection.

“I don’t think I’ve ever been this hard before either, but I’ve never had a cute girl like you touching it. It feels good, my heart is pounding, and it turns me on like crazy. But is it really that big?”

She seemed to have a lot of experience, so he assumed she was just flattering him there.

“Hee hee. It’s not like I measure every dick I’ve dealt with, but this one has got to be up there.”

She laughed and gave him a mischievous look, but he gave her a serious look in return.

“Wait, you can’t distract me with flattery. You shouldn’t be doing this with a stranger! I don’t know what a girl like you sees in a guy like me, but you should only do this kind of thing with your boyfriend!”

“My boyfriend, hm? None of the guys who have approached me have been interested in a serious relationship. They’re only interested in sex and, with my personality, they assume I’ll just let them do it. I mean, they’re not wrong, but still.”

He seemed to have convinced her to take this conversation a little more seriously now.

“But you – your resisting my very hands-on advances and you’re actually concerned about me. Hm, I kind of want to see if you would make a good boyfriend, but that wouldn’t be fair to Suzuri, would it?”

She blushed and gave him a heated look.

“Ehh!? Wh-what!? I wasn’t offering to be- khh!? A-anyway, Erisa-san, y-you need to stop. If you keep this up- ahhhh!”

His erection grew even hotter as her fingers skillfully stroked it while occasionally altering how strongly she gripped it. An irresistible urge was rising up within him.

“I told you to just call me Erisa. I’ll call you Youta, so we’re even.”

“B-but…”

His heart pounded at the thought of speaking to each other like a boyfriend and girlfriend.

“Ahh, Youta, your dick is still getting harder. And it’s throbbing so much.”

“O-only because you keep teasing it like this, Erisa.”

When she whispered his name in his ear without an honorific, a bashfully happy arousal led him to call her name in the same way.

That special act caused his heart to beat extra hard in his chest before the tempo of his pulse quickened.

“Ahh, Youta. I want to see your dick for myself.”

A tremor ran through her well-proportioned body and she gave him a melted look of joy.

“Ehh!? W-wait! This is too much already!”

He was already close to exploding and that was from the stimulation through his pants.

“Let’s get a look at this bad boy!!”

But she impatiently unzipped his pants and pulled out his erection.

“Ahh! Ahhhhh!!”

The pleasure of her handjob had caused him to pump out lots of precum, so the sticky erection released from his underwear gave off a powerful scent and lots of heat.

“Oh, wow. It’s even bigger than I thought. And that perfect shape. It’s like the Platonic ideal of a penis.”

Several veins bulged out on the thick, copper-colored shaft and the widely-swollen head rose up at a sharp angle.

New precum flowed endlessly from the tip and she could only sigh in wonder while staring at the sticky meatstick.

(Eh? Even bigger? Was that not flattery before?)

He still found it hard to believe, but if it was flattery, she sure was persistent about keeping up the charade.

“Just look at that big, hard cock. Ha ha. Now, let’s see how it feels.”

Before his thoughts could keep up, she grabbed his penis directly.

“Ahhhh! Erisa, w-wait!”

Her feminine fingers had been more than enough through his pants, but now they directly wrapped around and squeezed his near-bursting shaft. The maddening pleasure and emotion made him gasp and he felt scorching heat rising up his urethra.

“I never get tired of this hard yet squishy feeling. Not to mention the heat, the throbbing, and the sticky precum. You’re enjoying this, aren’t you? I can tell from how wet you are.”

“Kh, ahh, let go…Erisa. I-I can’t stop it.”

He could not hold back the urge any longer, but she either did not notice or did not care as her hot breaths reached him and she rolled the head around in her fingers.

“Oh, and the head. That strange shape is what really makes it a dick and not just a rod. And this hole here is the source of that wonderful nectar. Ahh.”

She held the shaft tight while teasing the head with her thumb and forefinger.

She traced her finger along the ridge of the head and poked at the frenulum.

“Kwahhhhh! Th-that’s too good!! Ghhh, I-I…I’m cumming!!”

Pleasure pulsed through his body, filling him with heat from the tip of his penis to the tips of his toes.

“Hyah! A-already!?”

Surprised to find it swelling further and throbbing so soon, she held it even tighter.

A hot torrent erupted from his solid flesh.

“Khh, ahhhh!”

“Whoa, wowww. That is…a lot.”

A massive amount of milky fluid splattered all over her uniform.

She stared down at the gloppy mess coating her hand and uniform for a bit and then looked back up at him.

“You came that much from a simple handjob?” She gave him a teasing look. “You really are a virgin, aren’t you?”

“I-I am, but I…”

“Oh, come on. There’s nothing wrong with that.”

Before he could say anything more, she sealed his lips with her own.

“Nh, ah, ahh, ah…ahh.”

Their tongues tangled together in their mouths, he felt like he was floating, and his heart raced.

(What even is today? I’m on a train with my dick hanging out and kissing a girl whose uniform is dripping with my cum.)

That would normally cause a huge scene and he would be in major trouble, but on this car, the shaking of the accelerating train only seemed to push everyone toward greater sexual heights.

(I’m allowed to have sex here. I can kiss her, I can cum on her, and no one will say anything about it!)

He noticed an athletic-looking college guy lifting up and thrusting into an office lady who was supporting herself by holding onto the overhead handhold straps. A schoolgirl was bent over and clinging to the railing while a virile-looking office worker pounded her from behind, producing a nice slapping noise.

Turned on by the heat filling the car, he grabbed Erisa’s breasts while kissing her.

“Ah! Ah, ahhh…That’s more like it, Youta. Do you like my boobs? Ahhh.”

They were smaller than Suzuri’s enormous ones he had groped that morning, but they were still well above average.

In fact, they were the ideal size for her body type and he could feel their firmness through the uniform sticky with his own cum.

“Ahh, they’re so soft and warm.”

When he squeezed, he could feel them pushing back at his hand. When he dug his fingers into them, their beautiful bowl shape grew sexily squished.

“Hyah! Ah, ahh, that’s right, ah, ah, ahh…grope my boobs, ahhhh.”

She moaned sensually while tightly holding and gently stroking his manhood which had grown even harder despite cumming once already.

“Ahh, Erisa. Are you sure you want to do…this kind of thing with me?”

He was not her boyfriend and they were practically strangers since he had only just learned her name, but he hardly cared anymore thanks to the prospect of losing his virginity.

He knew he could not stop his arousal if it grew any further, so he asked that question while their mutual caress continued.

“Ahh, nh. Y-yes, you said I was cute. Suzuri likes you and she’d probably see this as a betrayal, but I can cross that bridge when I come to it. And more importantly, I just really want to have sex with you right now!”

She did not hide her burning desire while still feeling somewhat conflicted about her friend.

The stimulation through her uniform must not have been enough because she undid the chest of her blouse and pulled up her bra.

The smaller size allowed her bare breasts to have a perfect upside-down bowl shape and they jiggled seductively as they left her underwear. She guided his hands to those mounds exposed below her lifted bra.

“Ahh, bare…bare breasts! They feel amazing. Ah, ahh, they’re so soft and squishy. It’s like their perfect shape is sticking to my hands.”

He had thought they felt amazing through her underwear and uniform, but bare was something else entirely.

“Nh, ah, ahh, ahhhh. And I love how your…nh…bare dick feels. Ah, ahhh!! It’s throbbing so much. And it’s so thick and hard. Ah, ahhh. Touching my bare boobs is turning you on, isn’t it!?”

Her sweaty breasts seemed to grow softer and more melted every time he moved his fingers.

His erection throbbed and dripped with endless precum. She felt his arousal there, which made her nipples grow harder below his palms.

“You’re getting hard too.”

He pushed in on those swollen tips, held them between his fingers, and applied a lot of pressure.

“Khhhh! Ohh, ah, ah, ahhhhhhhh!!”

Her legs started trembling and she went limp.

“Erisa! S-sorry, are you okay? Wow, your nipples are sensitive.”

He quickly caught her and she wrapped her arms around his neck to support herself.

He thought me must have gone too far, but she pouted her lips and lightly kissed him.

“It just felt really good since you made them so sensitive with your massage. But that just means…I want more. S-so, you’d better take responsibility and go all the way.”

“All the way.” He gulped at that obscene-sounding phrase. “Y-you mean…but are you sure?”

“How many times do I have to say yes!? I want you so bad down here, so unless you absolutely hate me, give it to me now.”

She stood on unsteady legs and lifted up her skirt to show her soaked panties and the sticky drops running down her inner thighs.

“Wowww. You’re so wet. All because you want to have sex with me.”

It excited him so much to know he had aroused her so much.

“Of course I don’t hate you. How could I hate someone so cute and sexy that actually likes me? I want to do it with you too! I want to go all the way with you!!”

“Ahh, Youta!”

He pulled her hips in and pulled down her nectar-soaked underwear.

He could not see that part of her since they were standing facing each other, but a strong, sweetly fermenting scent of arousal reached his nose and his male rod throbbed while standing even more erect.

“I’ll stick it in…inside you.”

“Nh!! Ah, ahhh, Youta. Do it, stick it in me. Ahh.”

She stood on her toes and he crouched down some to get his erection under her and then the head parted her wet flower petals and entered the small hole.

“Kh, ah, ahhh. Your dick is entering me, ah, ahh.”

With the rhythmic shaking of the train, he slowly started to fill up her narrow vagina.

He must have been moving too slow for her because she used her own weight to bring it inside her even faster.

“Erisa! Kh, ah, ahhhhh!!”

The love juices acted as a lubricant while his manhood rubbed against her inner flesh to slide inside.

“Kh, ah, ah…it’s filling me up…more and more. Oh, ah, ahhh, it’s so thick and hot. Ah, ahhh. Your…nh, ahh, dick. It’s filling my naughty hole. Ah, ahh, ahhhhhhhhhhh!!”

(Ohh, th-this is her p-pussy. It’s so tight and the walls keep rubbing me and wrapping around me. I have my dick inside her. I’m having sex with her! It’s so hot and tight and amazing!!)

When the pleasure showed strongest on her face, the squeezing inside her grew stronger.

Pleasure and arousal swirled inside him while he felt the inside of a vagina for the first time.

(B-but this is on the train. This is the usual train I use to get home. And it’s a special women-only car where sex is allowed. This is my first time, but it’s on a public train. I’m having sex with a girl on a fucking train! You’re not supposed to do that.)

If they had been boyfriend and girlfriend and they were in a more romantic location, it would have fit the kind of happy memory he had imagined his first time would be.

But this was the usual train on the usual line and other people were engaging in even more indecent acts all around him. That gave his first time a perverted sort of arousal far removed from what he had ever imagined.

“Ah, ah, ahh, your dick is growing even bigger inside me. Kh, ah, ahhhhh! And it’s throbbing like crazy. Ah, ah, ahh!”

The maddening arousal made his penis rub at her inner flesh in a way that could not be seen from the outside.

“Ah, ahh, I can feel your dick. Ah, ah, it feels so good. Your dick, ahh, ahh, is so good!!”

“Ahh, Erisa. Doing this on the train is so fucking good, so I think I could get hooked on this train sex!”

“Kh, ah, ahh. I know what you mean, Youta. I’ve been hooked on it ever since I first tried it. Gh, ahh.”

She moaned seductively, pressed her bared breasts against him, and wiggled her hips to achieve even more sweet pleasure. Her lewd behavior tore down his rational mind.

“Erisa! Ahhh!!”

He held her even tighter like they were being crammed together on a crowded train and he began using the shaking of the train to make rhythmic strokes.

“Ah, ahh, yes, hold me tight. Ah, ahh, and hit me dieep inside. Ah, ahh! Your thick thing is rubbing me, ah, ahh, it keeps moving in and out of me. Ah, ah, you’re getting the hang of this sex thing. Ah, ahhh!”

He pressed her back against the door and pushed against her while thrusting up into her.

The strokes were not very long, but their sexual flesh was pressed more closely together, it reduced the burden of her weight, and it let them both feel the insertion more clearly.

“Ah, ahh, I can feel your pussy moving around me. Your hot juices are getting thicker and stickier. Ahh.”

“Only because your dick is – kh – throbbing so much inside me. Nh, ah, ahh, the tip is staying deep inside me while it moves around. Ah, ahh, I’m almost there. I can feel the heat growing within me.”

“Ah, ahh, the tip is hitting you deep inside. It’s hitting something that throbs and flows with hot juices. Ahhhh!”

As her vaginal flesh squeezed together and her love juices grew thicker, the indecent sounds of their short but intense strokes sounded all around them.

“Ah, ah, ahh, listen to that lewd sound, nh. Ahh, everyone’s taking notice. Ah, ahh. They’re doing even dirtier things, kh, but we’re making the most noise.”

Perhaps because of the train scenario, the car was oddly quite for how many people were having sex.

The people engaged in even more intense acts were starting to glance over to see what all the loud and sticky noises were about.

“Nh, ah ahh, they’re watching us. They’re watching us have sex.”

The short strokes made it look like they really were trying to have sex unnoticed on an ordinary train, so an embarrassed arousal grew in them when everyone focused on them.

More and more of the others stopped what they had been doing and started emulating the kind of sex Youta and Erisa were having.

“Ah, ah, ahh. The attention is making…my body even more sensitive. Nh, ah, ahh. When your dick hits me so deep inside, ahh, my hips nearly give out.”

When he gently stroked her back and neck while thrusting into her, she gasped and trembled like a jolt of electricity had run through her.

The other couples also emulated that sweet sort of behavior, so a decadent aroma grew thick and filled the car until it melted all of their rational minds away.

“Kh, nh, oh, oh, your dick…your dick feels so good inside me. Ah, ahh, I’m going to go crazy, ah, ahh, nh, ah, ahh!”

“And your pussy is squeezing me even more. It feels like you’re stroking me even without moving. Khh, I’m close too. The heat is rising from deep inside me!”

The gentle but thick sweetness grew inside him until it reached the bursting point and rushed back out.

“Erisa!!”

He grabbed her tight butt, lifted her up, pushed at her hips as if spreading her legs, and thrust even deeper inside her.

“Khhh, so deeeeeep! Ahh, ghhhhhhhh!!”

His penis head applied even more pressure to her sensitive womb.

She gasped but wrapped her legs around his thighs to ask for it even deeper.

The longing motion of her inner flesh turned him on even more.

“There’s so much hot juices in there while you squeeze me so tight. Khhh, oh, god yes!”

As if releasing everything he had been holding in, he pushed inside her vagina with a powerful thrust.

“Ahhhhh! Yes…yes!! Ah, ahhh! It’s so thick, and wet, and – ah, ahhh – so deep!! Ahhh, it’s…ahh…it’s just so much. Ahhhhhhh, yesssssss!”

Her female hole felt his powerful thrusts as the sweetest of pleasures.

“A girl’s pussy feels so damn good. Having sex with you feels so damn good. Train sex is the best! Ahhh, I can’t stop my hips!!”

“Ahhh, it does feel so damn good. Khhh! My pussy is still throbbing, so pound me harder! Pound me so hard it should hurt!”

Drawn in by their intense sex, the other couples intensified their thrusting, filling the train with maddening moans and sexual scents.

That created a feedback loop that further aroused Erisa and Youta.

“Suzuri has feelings for you, ah, ahh, so she should have dibs…ah, ahh, but sex with you feels too damn good!! Nhh, I’m so glad I did this. Kh, ah, ahhh, here it is! Ah, ahh, I’m going to cum now!”

“Ah, ahh, if you squeeze my dick that hard, I will too! Kh, I can’t stop it! Ahhhh, I’m cumming I’m cumming!!”

“Ahh, ah, ahhh, I can feel it!! Ahhhh, your hot stuff is hitting me, ah, ah, ahhh, deep inside. There’s so much of it! Ah, ahh!! I’m, khhh, I’m cumming, ahhhhhhhhh!”

His penis throbbed with her inner flesh wrapped so tightly around it and a maddening torrent rushed out.

It hit her womb which had already been hit by the erection’s pounding, so her well-proportioned body convulsed while she achieved sexual climax.

More and more sexual cries filled the train as others found orgasm too.

“Kh, ah, ahhhh.”

They held each other tight afterwards, the train slowed down, and they arrived at the next station.

“Youta, this is your station, isn’t it?”

“Hweh? O-oh, y-yes. It is.”

Her whispered question brought him back to his senses. He checked for himself while barely able to think and he reluctantly left their embrace.

“Nh, ahhh.”

He pulled his penis out and she trembled while a milky liquid spilled to the floor. His heart pounded when he saw it and he put his still-hard dick back in his pants.

“U-um, this is my stop. Uh, but, since we did this…does that mean we’re boyfriend and girlfriend now?”

They had revealed how they felt about each other and he felt like he could get along with her straightforward personality.

He had never had anything like a love life before, but he was excited at perhaps making his first girlfriend and felt a need to ask that embarrassing question. However…

“I was thinking about it and we’re definitely sexually compatible, but I think you’re a better fit for Suzuri and I want her to be happy.”

“Eh?”

He had expected them to exchange phone numbers and email addresses and make plans for a date later or something, so this unexpected answer left him staring blankly at her.

“But we can always have more train sex. Stop by to see me soon♪”

As the door slowly closed, she waved at him and spoke with an innocent smile.

Just like that morning, he stood motionless on the platform for a while after the train left.
