Popular busty actresses Kokoro Ayase and Mizuhara ride on an orgasm bicycle with a system where a dildo attached to the saddle moves up and down when you step on the pedal, and challenge a game of orgasm endurance with a prize at stake. "Just pedal, right? Easy! Easy!" the two say, but... the more they pedal, the more intense the thrusts become, and they urinate a lot, sweat dripping, their knees tremble, and their vaginas spasm one after another! As they pedal, shaking their big breasts, the dildo is swallowed by their big asses! In just under 10 minutes, their lower bodies twitch non-stop, and their upper bodies writhe in agony! "I'm coming, I'm coming, I'm coming!!!" The two screaming out loud are a must-see.
