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?

Des：Research on Sperm Flagellar Activity initiated by a female student in the schools biology department. A school ejaculation monitor was recruited to provide male sperm for the experiments. I was interested in how it was offered, so I went to the club and asked... I was hired immediately and started collecting on the spot! At first, it was about using a masturbator to assist ejaculation, but in order to collect the amount of sperm required for the experiment, the behavior continued to escalate...massage, mystery play, masturbation show, cosplay leg intercourse, etc. I didnt expect the science girl to be so perverted! !
