A room in a love hotel in Tokyo, men and women with various relationships, their common denominator is "recording SEX".I got the footage and edited it in about an hour.What kind of drama happened at the love hotel? "I'm always doing research on stem cells," says Rin-chan, who has a high deviation value both in Kao and in her head.I usually stay in a university laboratory and spend my days immersed in research.And today I dressed up and put on make-up and went to her first meeting in life...I got drunk with unfamiliar alcohol and was able to check in to a love hotel with a man I met for the first time.She flirts with a flirtatious college student called the Video Research Society... and what she picked up with great interest was her many restraints.Apparently, the research mind of pleasure has also caught fire.Then, the man restrained his hands, his legs, and even put a collar on him.This vulgar gap is irresistible.She gets wet, snatches the electric massager from the man's hand and puts it on the clitoris by herself to show off her perverted nature.A woman on top posture that makes a nasty sound even when inserted in the raw.Then, after pulling out the man's thing, he puts his own juice in his mouth and makes a jupojupo sound with his upper mouth, saying, "It's delicious with apple juice." I recommend mating with a perverted female dog who is enthusiastic about research and enjoys the chemical reaction of the juice.
