Kanata Tanaka, an introvert, and his classmate Mio Yamamoto, a cool and mature-looking girl, have been assigned to inspect the gym storage room.

Mio, who finds herself alone together with him in that room, has her guard up about getting assaulted; but out of nervousness she accidentally knocks something over, a clumsy mistake that she would never usually make. Kanata is unable to suppress his excitement at the sight of her being clumsy, which he finds to be cute.

In the middle of all that, a teacher locks the gym storage room by mistake. The two of them wait for a while, but help doesn't come. Kanata, who thinks Mio was actually thinking something erotic might happen, summons his courage and begins to massage her shoulders. Moreover, under the pretext of tickling her, he keeps touching her body over and over while she's dying of laughter. Between "playing around" and "being serious", he makes a mess out of Mio. While nearly fainting from all this she continues to guard her private parts, but she's got no way to resist a boy's strength and gives in.

This introvert who's lost control won't stop, and just like that, bareback sex! Raw creampies! While they're doing things like having sex in the missionary position and forceful doggy style sex, right outside the gym storage room there's a random love confession scene happening...!?

Kazuhiko and I have always been together since we got into university. He had unsophisticated clothes, heavy glasses and unruly, curly hair.

But one day, he changed his hairstyle. His rough, curly hair became silky straight, he switched to contacts, and even his taste in clothes changed.

I've always pretended not to notice the affection I've been getting from Kazuhiko, with the reason that I already have a boyfriend with who I'm in a long-distance relationship with.

I kept pretending even when I'm getting cheated on.
Even when all my calls to him go unanswered.

"Mitozaka, you're dissatisfied and unhappy."
"If he's truly your lover, it's supposed to be his duty to help ease your worries."
"It's strange that you're holding back on him."

Like I said, Kazuhiko, don't tell me those things when I'm feeling down...

On the way home from the usual drinking party. The drunken me, prodded by the devil, said some biting words to him who was diligently looking after me:

"Do you like me?"

Hey, give me a cheeky answer with your weirdly polite language, like you usually do.

"...please don't ...ask me something like that."

After saying that, he pulled my hand as I was making a miserable face, and then pushed me down onto the bed.

This is a story about that time he and I stopped being best friends, for just one night.

"I wanna try having sex with a good woman"
That was the protagonist Keiichi's longing. Keiichi has a childhood friend, Haru Momose, who is his only female friend. In any case, this girl has a pretty face.

"If I could do those things with her..."
When he realized it, Keiichi couldn't stop himself from thinking about Haru. In the meantime, Haru suddenly arrives at his house to bring him the wallet he dropped at school. While the two of them were alone in the middle of such an awkward atmosphere, Haru takes some sweets from her bag; In this exact moment Keiichi sees her panties... At last, unable to hold back with his reasoning, he pushes Haru down on the floor.

'This is the first time this has happened to me...'
At first, Haru resists, but Keiichi's cunnilingus quickly brings her to paradise.

"I'm also gonna take off my clothes soon."
And then, what appeared in front of Haru's eyes, beyond her imagination, was Keiichi's huge cock...

'That huge thing is going to tear my crotch!'
