Sex with my girlfriend

My boyfriend wants to have sex with someone other than me. So I ask a girlfriend of mine if she would like to seduce my boyfriend. And that's what she's doing now. She has sex with my boyfriend in front of me. First she sucks his cock deeply and then she rides him off. When she fucks him doggy, he comes really hard and squirts all his cum on her ass. Could I have surprised you with something so hot?
