OMG! Boyfriend caught with best girlfriend

I wanted to go shopping and said goodbye to my boyfriend before I left. On the way, I realised that I had forgotten my money and drove back to get it quickly. When I cum in the bedroom, I couldn't believe my eyes. There was this guy with his cock inside my best girlfriend! Are you still okay? What now? Well, I've wanted a threesome with the two of them for a long time and now would be the best option. I can always pull his balls out and do it again. So, clothes off and off we go. He won't forget this act in a hurry, but he probably won't forget the aftermath either ?
