Higashi and Chika had been dating for a week. Today, Chika invited him to spend the night at her place. As soon as he arrived, Chika couldn’t hold back, pulling down his pants and sucking his big cock. But just as they started, Chika’s older sister, Mei, came home. Mei was stunningly beautiful, especially with her huge breasts and devilish figure, making it impossible for Higashi to look away! After Mei left her sister’s room, she didn’t leave but stayed to eavesdrop on their lovemaking. At first, Chika refused to let Higashi fuck her, but after his pleading, she agreed—only if he wore a condom. Though disappointed, it was better than nothing. After fucking his girlfriend, Higashi went downstairs for a drink, and that’s when Mei approached him, seducing him by offering to let him fuck her bareback and cum inside her pussy! Unable to resist the allure of raw sex, Higashi officially betrayed his girlfriend. He kept secretly fucking her sister even when Chika was nearby. Even when caught, he didn’t stop, continuing to fuck Mei and cumming deep inside her pussy in front of Chika...
