Adolescent Adam 5: Prologue

A long summer break could feel very short.

That was generally how people felt when they filled their time with worthwhile activities, whether that was studying, fun, or club activities.

In that sense, the first half of an extreeeemely short summer break was about to end for Fujita Mutsuki.

It was August 7 and ten in the morning. The harsh sunlight would soon bring its intense heat.

“Ah…nn. Yes, Mutsuki-kun…there.”

“Micha-san…ah, ah, you’re squeezing so tight…”

Without the air conditioner on, a boy and a woman pounded their sweaty skin together with a blanket around them.

Mutsuki lost himself in devouring the brown skin that glittered with a wild light thanks to the sweat.

Her body was endlessly soft and smelled nice. The young boy could hardly be blamed for being so entranced. They clung to each other and pounded their hips together in the missionary position.

“Pant, pant… Hey, Micha-san. Can I kiss you here?”

“N, nnn. No, Mutsuki-kun. You kiss so hard you leave a mark.”

“…Okay.”

“C’mon, don’t pout. Giving me that look is cheating.”

When Mutsuki bent his eyebrows, Micha arched her back as if she had no other choice.

Her weighty breasts bounced up against her chin and Mutsuki happily sucked at the erect tips and kissed all over the mounds. Just as she had feared, he left marks.

“…Heh heh.”

She knew it would cause trouble later, but for the time being, Micha loved being marked by him. The look in her eyes softened.

She rolled them both over to switch from missionary to cowgirl.

“I need to pay you back for that♪ Where do you want me to mark you?”

She bewitchingly parted her blonde hair while moving her face in toward his collarbones.

“Um, preferably nowhere anyone can see when I’m dressed.”

“Request denied~♪”

She kissed him hard enough to leave a mark on the nape of his neck which his clothing would never cover in midsummer.

The two of them were engrossed in fucking like animals, but the foundation of their relationship was one of a simple and almost familial love. The little brother could not defeat the big sister, so he had to obediently accept it.

He had more trouble with these soft touches than with the sticky union of their sex organs, so a ticklish tremor ran through his body.

“…Kh.”

Instead of telling her he was at his limit, he reached for her brown bust with six lip-shaped marks on it. He massaged the softness of melted chocolate.

The kind boy’s rough caress was a sign he was about to cum. This young woman knew his orgasm better than anyone, so she saw right through it and bounced up and down on top of his body.

An obscenely wet noise escaped through the sweaty valley of her butt.

It was followed by the sound of sticky fluids colliding.

“Kh…hh…hh…Micha-san…”

“Ahahh~~~♡”

The boy moaned in bits and pieces as the pleasure of ejaculation spread from his lower stomach to his entire body.

The woman instead did her very best to suppress the moans that threatened to escape. Having his thick extract pumped into her womb first thing in the morning had brought her to climax, but her pride as the older one insisted she feign calm.

“…Ahn♡”

But the cum was so plentiful that it shot back out of her vagina and her hips reacted on their own, causing her chocolate butt to twist around.

“Pant…pant… How can you be so rough right after getting up, Micha-san?”

“It’s your fault for being so cute.”

They had only met three months before, but they were now family, sister and brother, mother and child.

And as the most loving couple, they brought their lips together simultaneously.

“So go get me a beer~♪”

“I can’t believe you.”

As the woman lay lazily in bed, the boy sighed and left the sheets.

“You only get two a day. Don’t forget that. This means only one more today.”

“Yes, yes.”

He knew she would probably end up drinking more than five more before the day was out, but he was kind enough not to say it as he put on his pants and shirt before leaving the room.

They were on the top floor of a high-rise apartment building, so the open window let the summer wind and sunshine in. It was about time to turn on the air conditioning, but the wind felt nice and cool.

“…Phew.”

Three months had already passed since moving to this apartment.

That was also when the angels, demons, and humans of FeTUS had begun a three-way war over him.

A lot had happened in that short time. He had left his family, nearly died in a car chase and various attacks, and entered into adult relationships with Micha and several other women, girls…and a boy.

None of it had been easy, but it had been fulfilling enough to seem incredibly short.

He had nothing to worry about at the moment.

And he hoped these peaceful days would continue.

He opened the drink section at the very bottom of the refrigerator.

As always, it was stocked with as large a selection of alcoholic beverages as a store. He sighed and pulled out a beer plus a mineral water for himself. And then…

“Oh, good morning, Ange.”

The door to one of the bedrooms opened. It was the one on the other side of Micha’s room from Mutsuki’s room.

His other roommate, Ange, let her ankle-length red hair scatter behind her as she stomped into the kitchen.

“Do you have to make so much noise in the morning!? I can’t sleep!”

She yelled at him.”

“Oh, sorry. You could hear that?”

“Every bit of it! It’s hot enough as it is!”

The walls were apparently thinner than he had thought. With three people living here, it could not be fun to have the other two enjoying themselves first thing in the morning. Mutsuki smiled bitterly.

Ange continued yelling in anger, snatched his mineral water, and immediately started to drink the entire thing.

He noticed she was quite sweaty.

“…Ange.”

She did not have Micha’s seductive sweetness. Her body gave off a sour-ish girly aroma which caused him to gulp.

He gently reached out a hand and touched the soft throat she had exposed to drink the water.

There was a single small mark on her heated and sweaty skin there.

“This still isn’t gone? Sorry.”

“I-it’ll go away soon enough. I’ll admit it’s a problem, though.”

“Sorry. I seem to go overboard when I’m kissing.”

“~~~”

Ange must have recalled when he had given her that mark because she set down the water bottle and wrinkled her brow.

She was one of the girls he had entered into an adult relationship with.

“How long were you listening in?”

The boy smiled cruelly.

He alone could tell. While Ange did work up a sweat easily, this stickiness covering her skin was not from sleeping in the summer heat.

“You shouldn’t eavesdrop. I don’t mind, but try to think about Micha-san’s feelings.”

“D-don’t be stupid. I was not eaves-…ahh.”

She started to make her usual look of displeasure, but when he faced her directly, she grew more timid.

The boy had just finished having sex and his skin was covered in the same sort of sweat as hers.

Even if she tried to act tough, innocent Ange was hopelessly weak against that passion.

And Mutsuki was feeling bold thanks to the lingering arousal.

“…Want to join in?”

“What!? Wh-wh-what are you…?”

“Looks to me like you do.”

He moved his face in close.

“Don’t be stupid. Um…d-don’t be stu-…”

She continued trying to complain, but she was overwhelmed by the powerful scent of his sweat and she could not escape.

She did not move her lips away from his approaching ones. And…

“Mutsuki-kuuun? Where’s my beer?”

“Zwaaaahh!!”

Just before their lips touched, Micha poked her head out. Mutsuki’s body flew through the air 0.1 seconds later.

A single punch from the strongest angel was all it took. He flew from the kitchen and into the living room.

“Cough, cough. That hurt, Ange.”

“I don’t care, you pervert! Stupid, stupid, stupid!”

With that said, she fled to the bath with the mineral water in hand.

As Mutsuki coughed while feeling like his organs had nearly flown out of him, he watched her leave with a bitter smile on his lips.

He had lived with her for three months now and he had gotten closer to her in more ways than one.

Nevertheless, Ange was still Ange.
