Nozomi Sakai takes on a cowgirl challenge: if she can make the man cum within five minutes, she wins. She gets his cock hard with a slow vacuum blowjob, then wraps her massive, full K-cup breasts around it for a luxurious titfuck. Once he is ready, penetration begins and the clock starts. Can Nozomi make him finish in time? If she fails, the penalty is a hard doggy-style pounding followed by taking the withheld load in her mouth.
