With aphrodisiacs and a big dick, even a disgusting old man can easily corrupt a pretty girl with a boyfriend, making a complete mess of her life. (Natsukura Rika, SONE-718)

She was bright, pretty, gentle, and had a great personality. Plus, she had a healthy, voluptuous figure. Hiring Rika was a huge relief... Then one day, during a casual intimate encounter with the manager's permission, I witnessed an unbelievable sight. That unremarkable part-time boy was holding her hand... She actually has a boyfriend? This can't be real... I've been so good to her... Damn it!!! By the time I found out, I had already put a super-powerful drug I ordered from abroad into her drinking water... Rika, hahaha, you asked for it. I couldn't hear her screams, only repeatedly thrusting my proud, huge cock and the aphrodisiac. The effects were superb! Tears gushed from her pure little hole, she repeatedly reached orgasm and spasmed, becoming obsessed with actively seeking my penis and the drug prescription successfully turning her into a premature, useless vagina! Great, I protected this girl who couldn't be a boy.
