I'm looking for a doujin that fits this theme. The female is blonde, what I would describe as a shortstack, with very large breasts, the man is very muscular. They are both in the science club at college I believe, the girl gives the guys some drugs which are supposed to make him uncontrollably horny and his penis bigger, but he doesn't want to ruin the relationship so he holds back at first, she has a size difference fetish, and I think a "getting used for sex" fetish. Does anyone know the name or the artist name?
