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! !
