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! !
