[ZENmocap] I participated in the secret ejaculation research club held after school,and was worked so hard that my dick went numb,as if to say,"Even if you ejaculate,you won't be allowed to go home!"

Overview： Motion capture & CV: YUU,Izumi Sakura,Yozuki Rin The "Ejaculation Research Club" is a secret after-school program run by the girls at the top of the school's caste system. In this research,they are researching how to arouse a guy so that he will produce a lot of sperm in his balls,and how to efficiently lead to a rich ejaculation. I,who am at the bottom of the caste system,was called to participate in this research. I was used as a practice dummy for practical skills such as "handjobs," "fellatio," and "cowgirl position," and the research escalated to perverted acts such as "edging," "making him hold a dildo in his mouth and giving a blowjob in front of me," and "being showered with squirting" as part of the research to excite my penis. I,who am at the bottom of the caste system,couldn't resist them,and even if I tried to run away,I was restrained so that I couldn't move,and I couldn't go home until everyone's research was finished.
