MFT-005: When I heard that sperm was being recruited for an experiment in the Biological Research Department, I was immediately hired and overtaken by a cute female science club member! - "Can I get out a little more?" and I was made to until sperm stopped coming out for research!

Girls in the school's biology research club started research on "flagellar activity of sperm". The school ejaculation monitor was recruited to donate the male sperm necessary for the experiment. I was interested in how it was provided, so I went to the club room to ask ... Immediately adopted and started collecting on the spot! At first, it was about using a masturbator to support ejaculation, but the act escalated more and more in order to collect the amount of sperm necessary for the experiment ... I didn't think that science girls were such perverted girls such as Kintama massage, hidden word play, masturbation show, cosplay intercrural sex, etc., so that a lot of sperm can be made in the gold ball!
