A couple is in the middle of an abstinence game, saving themselves for a month so their reunion sex will feel incredible. But when the long-awaited 31st day finally arrives, the boyfriend is suddenly sent away on a business trip. His J-cup girlfriend is left at the breaking point, with her sex drive completely out of control—and the best friend he trusted pins her down. “I’m sorry... I held back for so long that I couldn’t take it anymore...” The friend steals the sex the boyfriend had been waiting for and fucks his beloved girlfriend over and over like an animal, unleashing all her pent-up lust in an intensely filthy betrayal.
