ALDN-480 Family Love Contract Umino Kitano

Living with my sister, her unemployed husband (my brother-in-law), and my younger brother for three months. My sister, who was doing housework for a meager wage from my brother. One night, seeing my sister comforting the depressed brother-in-law, my brother felt something strange in his crotch. One morning, while cleaning the room, my sister lifted the comforter to find her brother's erect penis and felt something amiss. One day, while drinking together, it was discovered that my brother was paying a considerable amount of money for sex services. "What?! You're spending that much? What a waste! Give me that money insteadw hahaw" my sister said, confusing my brother, but he went along with the mood and started negotiating, "Huh? If you pay me, it's finew." Driven by alcohol, they started some weird compatibility check, getting more excited and unable to stop… Both of them, while trying to be rational, crossed a line and things escalated further between my sister and brother.
