My cousin takes advantage of my uncles going out of the house to convince me to have sex

My cousin has always been a tough girl, and when we were kids, she would sometimes catch me rubbing my penis secretly from our parents. For this reason, since we were kids, I got used to wanting her, but unfortunately when we grew up, she moved very far away. Today, now that I’m grown, I decided to go visit my aunt and uncle’s house on vacation, and to my surprise, my cousin still desires me as much as I desire her. When my aunts go out to the supermarket to do the shopping, my cousin’s pussy approaches my door with the proposal of fucking while her boyfriend watches on video call. It was surprising to me, but my desire to penetrate her was so strong that I just agreed. She sits on top of my penis and begins to bounce up and down like an expert before giving attention to her boyfriend and then giving me the best blowjob of my life.
