Popular actresses Mizuki Yayoi and Mizuki Sakino ride on an ACME bicycle, a system where a dildo attached to the saddle moves up and down when you step on the pedal, and compete in a game of orgasm endurance with a prize at stake. This time, it is divided into three parts: “An orgasm endurance cycle without being found out at a serious talk show”, “An orgasm drive masturbation while enduring orgasms”, and “A 30-minute one-on-one match with the ACME bicycle”. The more you pedal in front of the audience, the more intense the pistons become, making the ACME bicycle an ultra-erotic hell! They try desperately to remain calm so that they are not found out, but they cum over and over again, squirting from between their legs and turning pale! Even though they are dripping with cold sweat, they can’t help but spread their legs wide and experience continuous vaginal spasms! “The truth is, I felt it so much (sweat)”. How will the competition turn out…? Don’t miss it.
