MVSD-382 - Semen Research Circle: We are looking for donors who are confident in their sperm volume! Mitsuki Nagisa

A depraved documentary where Mitsuki Nagisa recruits 'sperm donors' and thoroughly researches the quality and quantity with her own throat! It's a masterpiece to see this innocent-looking girl, faced with one thick cock after another, eyes glazed over as she passionately serves them, begging, 'Give me more...'

I thought the video was cute and her facial expressions were really expressive. The swallowing part was great too!

It's pretty much the same thing from start to finish, so it gets a bit boring halfway through, but whenever I rewatch a random scene, I always end up finishing. How could you not get off when a girl this cute is comparing semen samples?

Out of all the 'gokkun' videos I've seen, this is the one I've finished to the most. It's packed with great moments—I never get tired of it!

I found it incredibly erotic when they compared the taste of the fluids by age group and shared their thoughts.
