Cowgirl specialist Emiri Momota has five minutes to make a male performer cum by riding him and win a cash prize; if she fails, her punishment is a forceful deep throat after he ejaculates. She may warm him up first, so she plays with his nipples and gives him a handjob and blowjob before the timer starts. Emiri attacks with bouncing, leaning-back, grinding, and reverse cowgirl while teasing him verbally and asking which style he likes. She keeps riding at full power even after time expires, cums from her own relentless effort, and ends by admitting with a smile that she is frustrated to have lost.
