One of my all time favorite fantasies. I always wanted to have my girlfriend walk in on me and another guy dressed in some of her lingerie and making love to each other. As we are sucking each other off she comes in on us. I wouldn't stop until he cums in my mouth
to Openandwilling66 :Now that is a great fantasy! I have a very similar one, where the room maid walks in and sees us both wearing lingerie and wants to watch until the end!
