My husband and I spent a week with my college roommate and her husband at their summer place over the summer. We did a lot of drinking and just hanging out. One night my husband pretty much passed out and the three of us stayed up. My friend and her husband were getting frisky. They went to their room but they didn't close the door. I was drunk and curious and looked in on them a little while later. My friend was sucking on her husband's cock which was as big and impressive as she'd always described it. My friend asked me if I wanted to join them. I said no. I asked if I could watch and she said yes.

I sat on the bed right next to them while she serviced her husband. While I watched, I started lightly touching myself. I rubbed while she sucked. Her husband lightly rubbed my leg while this was going on. I ended up pulling my shorts and panties off to masturbate for real while she kept sucking. I stared at her sucking his beautiful cock while I diddled my clit and her husband gently rubbed my bare inner thigh. When I got close I started gasping and he slid a couple of fingers into me and grinded into my g spot while I came. My friend watched me cum with a little smirk on her face while stroking his dick and then went back to her sucking.

I lay there with my pussy exposed, her husband running sliding his fingers up and down it it while she sucked him til he came. She used her hand to finish him so I could watch his cum spurting into the air and then land on his chest and belly. I shouldn't have but I helped her lick up his cum.

That was the closest I've come to actually cheating on my husband. When my friend invited me to join them I wanted to so bad but I just couldn't bring myself to do it.
