Slender, fair-skinned Yui Shinjo takes on the Cowgirl Position Time Trial! The rules are simple: she must make him creampie within 5 minutes of penetration. Succeed, and she wins a fantastic prize—fail, and she faces a punishment game. Before insertion, she delivers a slow, sticky vacuum blowjob, nipple teasing, and handjob to fully erect his cock, maximizing pleasure upon entry. Despite grinding her slim hips and desperately trying to trigger ejaculation, she ultimately fails the challenge. Although she misses out on the Okinawa trip, she enjoys numerous creampie orgasms from his cock.
