I never used to like threesomes, I always liked getting all the attention from the guy I'm fucking. I wanted to be the girl that he lusted over, and yearned to be with again. I love watching a guy moan with pleasure as I solely focus on him and the idea of another girl made me feel less special.
That is until I realised something. Outside of sex, I am super competitive and threesomes allow me to compete with the other girl. I was asked to have sex with one of my not-so-close friends and her boyfriend (It was one of those deals where the guy picked me and she got to pick one of his friends for their next threesome). I know that he had been instructed to focus mainly on her and to not cum inside me. But to me, this sounds like a challenge. A challenge to be sexier than her, to try harder than her, to make him feel better than she ever could.
So when it finally happened he started by playing with his gf... It took some time for him to start fucking me, but when he did I made sure to take him so well. I pushed back hard against every thrust and made sure he couldn't take his eyes off of me. I hadn't touched myself all week so that I would be super horny and now all I wanted was for her to see how good he makes me feel and how much I loved his cock. My goal was to watch her get jealous as my eyes rolled back and my legs got weak. She was in front of me with her pussy in my face, and I was doing a bad job to make her feel good. I was doing just enough to keep her there.
After about 5 mins of him using my pussy I could feel him start to twitch, he was getting close to cumming and he was slowing down. I looked back at him and told him not to stop. I said "I need it, don't fucking stop, please Ryan, please don't stop" and he knew exactly what I wanted, but she couldn't be sure i meant his cum so she didn't say anything. He started fucking me harder, and I moaned louder trying to hide the noise he was going to make when he came inside of me. I clenched my pussy tightly down, enough for him to feel his cock being locked into place and his cum exploded inside of me. It felt so fucking good for the both of us, he collapsed down onto me as she stormed off. He was exhausted from cumming so hard that it took him a couple of minutes to get off of me and go after her. Later that evening she blocked me and I was never asked to join them in a threesome again.
