Matsumoto Nanami (Godly Tits J Cup), Hoshino Nami (Plump and Big Ass), Okuda Saki (Transistor Glamour), Aoi (Beautiful H Cup) - These are the four strongest bodies that S1 boasts of, performing together for the first and last time! The ultimate hospitality is what this ultra-luxurious soapland prides itself on. Enjoy the bodies of the four in a soap! A SM club with elaborate themes! A men's esthetic where the four take turns with the penis! Double oppabu and double pinsaro! A four-wheeled image club with proud costumes! If such a soapland existed, I'd want to spend all my wealth to experience it!
