[ZENmocap] When I participated in a secret ejaculation research club that was held after school, I was teased until my dick became stupid, as if to say, “I won’t let you go home even if you ejaculate!”

Summary: ❤️❤️❤️ The “ejaculation research club” is held secretly after school by the upper caste girls in the school. In this research, how should we stimulate the sperm to fill the balls? How can we efficiently lead to thick ejaculation? are researching. As someone from the bottom of the caste, I was called to participate in such research. It is used as a training ground for practical skills such as “hand job”, “fellatio”, and “cowgirl position”, and is also used as a study to excite the penis, such as “stopping it”, “having a dildo in its mouth and giving a blow job in front of it”, “being showered with squirt”, etc. It escalates into perverted behavior. Being at the bottom of the caste, I couldn’t go against them, so even if I tried to run away, I was restrained so that I wouldn’t get violent, and I couldn’t go home until everyone had finished their research.
