What started as a casual game of strip mahjong during a home party turned into something unexpected! We thought we were just playing with a beginner girl, but the moment Marina-chan changed into an erotic costume for a penalty game, she completely transformed into a "lucky nympho." With hands like a pro, she hit Kokushi Musou and Daisangen! Before we knew it, we men were completely broke, forced to kneel naked before her. We didn't pay with points or money, but with our "cum" as she demanded! Every time she won a Yakuman, she followed up with a relentless, intense titjob and forced creampie, squeezing every last drop out of us. "The night is just getting started, isn't it?" she smiles, while our crotches are left exhausted and empty. *The mahjong descriptions in this work are supervised by Marina Yakuno herself.
