Punishment Game Between Hare & Tortoise

"Sorry~! That confession was just a lie for a 'punishment game.' But I'll play the part of your girlfriend for today, so forgive me, okay? ♪"
Ichizo Kameya a.k.a. "Kamechi" finds himself the target of a confession from Sagiri Indo a.k.a. "Usako" as part of a punishment game. She's a girl with a voluptuous, soft, and bouncy body.
To make it up to him, she agrees to act as his girlfriend for the day; she starts fondling his crotch, and the mood quickly turns erotic! However, Kamechi—who is well-endowed but suffers from premature ejaculation—blows his load twice in rapid succession thanks to her handjob and titty-fucking, causing her to lose interest in him almost immediately...
Frustrated—both in his head and in his cock—by his sassy classmate’s incessant, selfish complaining, he decides to vent all his pent-up irritation by thrusting his massive member deep into her pussy!!
A young couple going wild with lust and non-stop sex!
A serious "breeding" session that breaks a selfish, gal-style high school girl's spirit and makes her submit to his cock! ♪
