Ero-kawaii beauty Futaba Mio-chan challenges the 'Riding Position Time Trial!' The rules are simple: if she can make her partner ejaculate in the riding position within 5 minutes, Mio-chan wins! If she loses, there's internal ejaculation, butt rubbing, and a cleaning blowjob! Confident Mio-chan. Once inserted, she starts counting the minutes, showcasing her seductive skills to get his penis fully erect! Making naughty sounds, she sucks his penis while looking into the camera! "May I start inserting now?" she asks with a relaxed smile. Yielding to the man, "I'm going to insert it~" she rides him herself in the riding position! "It's inside, look closely," she breathes in a cute voice, mixing in euphemisms as she gasps, inviting excitement, and vigorously shakes her hips in the vertical riding position! On the bed, the camera angle is almost entirely from the male perspective, creating an immersive experience! Witness the full commitment of a popular AV actress! Ah!?
