After having a relationship with his sister, Takashi continued to play with her in a sexually perverted way. Yumi on the other hand, has been working hard on expanding her asshole and training herself to feel the pleasure of coming after witnessing Takashi and his sister's act. One day, Yumi who had been waiting for his sister by mistake, walked into the house and pulled up her skirt, love juice dripping from her underwear-less crotch, her face elated. Seeing her in such a lascivious state, Takashi reflexively devoured both her pussy and her asshole, thrusting his meat stick into her shame without stopping. Yumi's asshole was being tortured relentlessly and she climaxed several times, but her body was nearing its limit. She and Yumi decide to share Takashi's dick and soon the three of them are at the peak of their lust!
