Men suddenly attack an innocent girl (high school student, OL, college student, etc.) who has come to a deserted bicycle parking lot. They forcefully pin her down, strip off her clothes, and expose her body! They restrain her hands and feet to the bicycle! They also attach fixed vibrators, fixed electric massagers, and fixed rotators, then leave her there! The girl, in an embarrassing pose, feels a thrill of not knowing when someone might come, along with lewd stimulation, causing her body to gradually become aroused! The wet private parts of the innocent girl, who can no longer hold back, easily allow penetration by the penis, and her breasts are groped relentlessly, leading to forced orgasm from intense pistoning!
