"When a man and a woman are invited to a love hotel as friends, will they challenge each other to a sex game with a prize of 100,000 yen when they are left alone?!" A thorough investigation! A college girl with a boyfriend who boasts that friendship between men and women is possible is persuaded by a one-night stand-type sex-loving senior and falls for it! Pretending to be swept away, she makes excuses to herself and accepts a raw dick, getting a lot of sperm and prize money from continuous creampies!
