Movie Information:
A study on “sperm flagellar motility” started by the girls in the school’s biology research club. They recruited “school ejaculation monitors” to provide the male sperm needed for the experiment. Curious about how the donation would work, I went to the club room to ask… and was hired on the spot! At first, they said they’d just use a masturbation sleeve to help me ejaculate, but to collect the amount of sperm needed for the experiment, things kept escalating… To make sure my balls were packed with sperm, they gave me testicle massages, used dirty talk, made me watch them masturbate, and did cosplay dry humping—I never imagined science-minded girls could be such perverts!!
