Professor Ryoko is obsessed with studying male semen at her university, but strict ethics prevent her from analyzing samples from minors. To satisfy her research needs, she takes a side gig as a substitute high school teacher, where she begins collecting her 'specimens' directly from the students in the classroom.




















I turned a blind eye to the 'actors who look nothing like high schoolers' and focused solely on Ryoko-san's wild performance. There are many beautiful mature AV actresses like Ryoko-san, but I can only think of 'Maki Tomoda' who could pull off a role where her beautiful face gets completely covered in cum like this. On top of that, she even squirts, so there's no way I could give this a bad review. One actual sex scene feels a bit low, but the cum play is so substantial that it more than makes up for it. All I can say is, 'Ryoko-san is the best!'
Ryoko Murakami, the 'semen-swallowing sensei.' Her body is starting to sag a bit and those crow's feet are showing, but I'm sure drinking all that semen will make her feel young again.
It's rare to see a woman around Ryoko Murakami's age, or older, engaging in cum play. Dressed as a female teacher, Ryoko Murakami collects a young man's cum and swallows it. With 15 vibrator masturbation scenes, 20 cumshots during sex, and a few others, it totals 42 shots. She keeps interacting with the cum while whispering dirty talk, ending up with her face completely covered in a massive facial cumshot. Even then, she continues the performance without flinching. Truly a veteran AV actress.
