I got back from the gym, and running to the store earlier than expected. There was an unfamiliar car parked in my driveway. When I opened the front door, there was music blasting from upstairs. I knew right away that my husband had another woman over. He had joked about it last night, but I didn't think he'd have his friend over again so soon. I rushed up the stairs without trying to make too much noise. Behind our bedroom door, I could see my husbands old coworker (Lena) on top of him, grinding her body on his cock. I should have been upset or raging with jealousy, but all I could do is watch with a "forbidden" interest. She had quite the erotic moves. I started playing with myself when they 69ed with eachother. His face was buried in her pussy, while she licked and sucked on his throbbing cock. After a few minutes she was riding his face, when she came all over it. He flipped her over to fuck her doggy style. As soon as I saw how hard he was pounding her from behind, my fingers were coated with the juices of my orgasm. He held her arms from behind and was fucking her roughly. She was moaning so much from the pleasure. My husband unleashed his load deep inside of her a couple of minutes later. I decided I would talk about this later with my husband, and crept back outside to my car. I was waiting in it when Lena came back out to her own car. She waved and acted like she hadn't just fucked my husbands brains out. I smiled and waved back as she left our driveway. Pretty soon I'll be chatting with hubby about his new friend, and if they plan to let me join in. 🤞
