A man and a woman who are not interested in each other are drinking at home. "I can't see you as a man lol" "I can't see you as a woman either!" With each other not even considering the other as the opposite sex, a little show-off and drunken momentum start a "touch each other, whoever cums first loses" game! However, just being touched makes the dick twitch! Just touching it makes the pussy slippery! Until now, they hadn't realized that "in fact, their bodies are so compatible that they cum instantly" and the game is unsettled between the small-time dick and the small-time pussy! The quagmire-like orgasm competition becomes more and more extreme, and it's now even more intense than sex between lovers!
