Movie afternoon ends in threesome with my friend Mariana Martinx's best friend

Mariana Martinx invites her best friend to watch movies in her apartment. He includes me in the plan, he says that three is better than two for a Sunday afternoon. The three of us on the sofa, shared blanket, popcorn that runs out quickly. The movie is boring. Mariana leans on her friend's chest, I lie on the other side, and between laughter and comments our hands begin to rub under the blanket. She is the first to move. He pulls down his friend's pants, looks me in the eye and invites me with a gesture. We both suck his cock in turn, kiss with our mouths full, look at each other while he moans between us. Mariana takes off her shorts, climbs on top of it and orders me to sit on her face.
