"Hey, look at this! I'll go tomorrow." Akari, a housewife struggling to make ends meet, finds a part-time job as a monitor and takes part without much thought. However, what awaits her at the venue is a modified exercise bike. The 5-cylinder vibrator on the saddle attacks her clitoris, bringing her to instant orgasm. As soon as she falls to the floor, the staff member's young cock stirs her vagina, sending her into a burst of orgasms. Akari, unable to forget the pleasure she felt, continues to visit the venue without telling her husband.
