Me and my BF had been talking about threesomes for a while, but the thing that turned me on most was the idea of watching him with another girl. Sure, I’d like to fuck another girl too, but just watching felt like a good place to start. We found a girl who was up for it, and invited her over.

Everything about the hook-up went smoothly. We were chatting and laughing, and then we moved into the bedroom. My boyfriend and the girl got onto the bed, and I sat in an armchair beside them. They made out together, laying on the bed, but my boyfriend glanced at me a few times and gave me a nod. I nodded back to him. I was having great time just watching them.

As they started to strip, they checked in with me more. They asked how I was feeling, if I was enjoying it, and I told them I was. It felt good to share that with them, to tell them how beautiful it was to see them together and how hot it made me feel. Then, they gave me an even better show.

I watched the girl start to suck on my boyfriends cock. I loved seeing his cock in that other girl's mouth, to see something I had done so many times before from this different perspective, and I started to touch myself. I thought about getting involved, of kissing her and sharing my boyfriends cock, but I was just so mesmerized by watching. So, I started to touch myself.

She climbed on top of him and started to ride his cock and that turned me on so much. I heard her moaning as I stroked my clit, getting closer and closer to cumming. I watched her breasts bounce and my boyfriends cock slipping in and out of her pussy. I looked at my boyfriend, saw how much he was enjoying himself, and I came to the sight of it. It was so erotic, even more than I had thought it would be.
