IPZZ-742 Wakana Sakura, a beautiful girl with a plump ass, joined the swimming club in an attempt to change her weak and shy self, but was trained by her perverted advisor to have sex with her and get creampied.

Of course. A young body that repels water...a delicate waist, a big ass. A talent worth training...but above all, a thin, weak, fragile, unfortunate girl. A shy girl who seems likely to be sexually assaulted... As a perverted advisor, I trick her into drinking, trick her into drinking, and then I trick her into drinking an aphrodisiac... and I'm corrupting her into something vulgar. Now, it's about time she begs for a creampie. After all, awakening immature women to their sexuality is part of my job as an advisor to educate students...
