Tachibana Serina's Ladder Alcohol! Full erection tipsy, intense sex

All the staff members fail to pick up girls, and then one of them contacts a staff member! They invite her to come because she's drinking with her friends! They say they can turn the camera around so they sneak into a drinking party! From the private drinking video to the sex footage that looks like it's private, and even when she secretly gives them a beer with aphrodisiacs, she transforms into a lewd, erotic and lewd Seri-chan, who is private! I've never seen a private video like this!
