I live with my mother-in-law. Because our home had become too cramped, we decided to go ahead and renovate it. During the renovation, my mother-in-law, my wife, and I had to sleep side-by-side in a "river" shape. I hadn't had sex with my wife since we started living with my mother-in-law, and seeing my mother-in-law in her chemise made me so horny that I couldn't sleep. The next day, the three of us were sleeping side-by-side again. In the middle of the night, I heard moans leaking from my mother-in-law. I stared intently at her as she pleasured herself alone. The next day, after confirming my wife had gone out, I hugged my mother-in-law and told her what I had seen yesterday. When I pressed my already hard cock against her, she knelt down and made me feel good. Then came the night. The three of us sleeping side-by-side. I woke up feeling something strange between my legs, and found my mother-in-law sucking my crotch as if savoring it...
