I'm a member of the science club who loves erotic things, so I made a prototype aphrodisiac! But I didn't have the courage to try it on the girls, so I couldn't get any results... But one day, a female member of the club accidentally drank the aphrodisiac I was making! The normally modest club member changed completely! She transformed into a lustful science girl who was arousing! She reacted with a trembling reaction just by touching her body! The unstoppable female member begged for my dick, and I ended up having to collect every drop of sperm!
