"What?! No way… my sister-in-law??" My serious sister-in-law, Mei, who used to look down on me, a freeloader, showed up when I called an escort service… Is such a miracle even possible?! I had her weakness and gave her orders, and her hidden L-cup breasts were revealed, and the forbidden service began. "Sister-in-law… this feels better than your brother's dick, right?" I asked, thrusting hard, and Mei, who was initially reluctant, was at the mercy of her brother-in-law's huge cock and gradually transformed into a submissive female… From sneaky fondling while our parents were out, to a full-service booking at a hotel for a long session! The sense of transgression was the perfect spice, and I vigorously developed her slutty pussy. At first, my sister-in-law was cursing me, saying "You're the worst…", but in the end, she was sucking me off herself, completely corrupted. Sorry, big brother! Your big breasts were too erotic, and I vigorously thrust into your long-neglected slutty pussy to develop you into the best submissive wife ever lol
