MFT-005 When I Heard That The Biological Research Department Was Recruiting Sperm For An Experiment, I Was Hired Immediately And Was Overtaken By A Cute Science Female Member! “Can You Put Out A Little More?”

Research on “sperm flagellum activity” started by girls in the school’s biology department. A school ejaculation monitor recruited to provide the male sperm necessary for the experiment. I was interested in how it would be provided, so I went to the clubroom to ask…I was immediately hired and started collecting on the spot! At first, I was talking about using a masturbator to support ejaculation, but in order to collect the amount of sperm necessary for the experiment, the act escalated steadily… Massage, cryptic play, masturbation show, cosplay intercrural sex, etc. I didn’t think science girls were such perverted girls! !
