Kouichi, a handsome guy with light brown hair, has the look of a modern young man. While restrained in his bikini, he is tormented by the dominant "Yuito," causing his penis to swell progressively. His thick shaft grows so large it seems ready to tear through the bikini, becoming increasingly sensitive under the vibrator's stimulation. With an attachment fitted to fully encase his massive cock, he writhes in ecstasy, gasping, "I'm about to cum already." Beneath the smooth-skinned youth's anus waits a fixed L-sized dildo. As he lowers himself directly onto it, his thick, swinging cock grows larger with each motion, achieving a rock-hard full erection. His relentless hip movements exude an intensely erotic spectacle.
