Пришла в гости моя мачеха. Она научила меня, как кончить в ее тугую задницу.

My uncle's wife came to visit. They asked me to show her the room where she will sleep. As soon as I saw her I noticed that her look had something different. And immediately I noticed how my pants squeezed me, about to explode. She realized that I undressed her with my gaze.
