19F My boyfriend let his best friend use me while he watched

We’d talked about it for a while the fantasy of him watching me with another man. I thought it would stay a fantasy. Until one night, he told me, “He’s coming over. I want you to fuck him.”

I laughed at first… but he wasn’t joking.

His best friend showed up like nothing was out of the ordinary. We all had drinks, chatted, flirted. My boyfriend told me to sit on his friend’s lap. I could feel the bulge in his pants right away. I looked at my boyfriend and he just nodded.

Next thing I knew, I was naked on the couch, riding his friend while my boyfriend watched with his cock out, stroking it slowly. I was moaning loud, soaking wet, taking every inch of his best friend while my boyfriend just whispered, “That’s it. Show him how good you are.”

His friend fucked me hard from behind, pulling my hair, slapping my ass, while my boyfriend sat right next to us, telling me how hot I looked getting used. I came on his cock while looking my boyfriend straight in the eyes.

After he came inside me, my boyfriend cleaned me up with his mouth.
And now… we’re planning to do it again.
