I Heard the Biology Club Was Recruiting Sperm Donors for an Experiment, So I Went to Check It Out and Got Immediately Hired, Then Got Jerked Off Nonstop by Cute Female Science Club Members! "Can You Ejaculate a Little More?" They Made Me Keep Fucking Until My Semen Ran Out for Their Research! Who's the JAV actress in this video? Amateur? Name revealed!

The girls of the school's biology research club have begun conducting a study on the theme of "sperm flagellar activity." To obtain the male sperm required for their experiment, they've started recruiting male volunteers for on-campus ejaculation monitoring. Curious about the methods used for sperm collection, I visited their clubroom to inquire further—and was immediately accepted as a participant, with sample collection beginning right then and there. Initially, they said they'd assist ejaculation using a masturbation sleeve, but in order to secure the large volume of sperm needed for the experiment, the procedures quickly escalated. From testicle massages designed to boost sperm production, to hidden slang games, masturbation shows, and even bare-legged grinding while cosplaying, I never would have imagined these studious girls had such a deeply perverted side.

なぜ外す？ 理系の女子キャラが登場する中で、3人中4人が眼鏡をかけているんだけど、結局最後には全員眼鏡を外してしまって、一体なぜか意味が分からなかった。眼鏡を外すことでキャラクターの性格や姿が変わるのかなと思ってたけど、それも特に描かれていない。ちょっと不思議な演出で、少し違和感を感じた。
