Threesomes

I have the biggest fantasy of my and my boyfriend having a threesome with a girl we met through mutual friends. But she has a boyfriend. But I always picture her laying on top of me and us making out while my boyfriend goes simultaneously inside me and then her mixing our juices 🤤 and then going down on each other or her riding my face. I’ve never thought about girls like this but something about her just gets me so wet 💦
