[MFT-005] When I heard that sperm was being recruited for experiments in the Biological Research Department, I was immediately hired and overtaken by a cute female science club member! I was made to until I couldn't get sperm out for research, "Can you give it a little more?"

Girls from the school's biology research department started research on "flagellar activity of sperm".
An in-school ejaculation monitor was recruited to donate the male sperm necessary for the experiment.
I was curious about how they were served, so I went to the club room to ask ...
Immediately adopted and start collecting on the spot!
At first, we talked about using a masturbator to support ejaculation, but the act escalated more and more in order to collect the sperm required for the experiment ...
I didn't think that science girls such as kintama massage, secret word play, masturbation show, cosplay bare thighs, etc. are such perverted girls so that sperm can be made in a lot of gold balls! !!
