ชื่อเรื่องเดิม: MFT-005 生物研究部の実験で精子を募集していると聞いて行ってみたら即採用されて可愛い理系女子部員に抜かれまくり!「もうちょっと出せる?」と研究のため精子が出なくなるまでハメさせられました!

The girls in the school's biology club began a study of "sperm flagellar activity. The girls in the school's biology club started a research project on "sperm flagellum activity." They were asked to donate male sperm for the experiment. They were curious about how they were going to do it, so they went to the club room to ask... They were hired immediately and started collecting sperm on the spot! At first, they were talking about using a masturbator to support ejaculation, but in order to collect the amount of sperm needed for the experiment, they started to escalate their activities... they started to give him a balls massage so that he could produce sperm in his balls, play with him in secret, show him how to masturbate, and play with him in cosplay... what kind of science girls do that? I didn't think they were such perverted girls!
