Riding position time challenge! Yui Shinjo 1pondo_120425_001

Slender, fair-skinned beauty Yui Shinjo takes on a cowgirl time trial! The rules are simple: if she can make him ejaculate within five minutes, she wins a prize. Failure results in a penalty! Before penetration, she first uses sticky vacuum-like oral sex and nipple-teasing masturbation to get his penis erect! She tries to make him ejaculate by twisting her slender waist, but fails the challenge. Unfortunately, she couldn't go on a trip to Okinawa, but she made him ejaculate many times with her penis.
