I Confess.... I'm a total bastard. I'm 47 and my wife and I were at a family barbeque this weekend. The booze was flowing and everyone had more than a little too much. Anyway there are two bathrooms on the first floor of my in-law's house, one attached to the master suite and one next to the garage. The one near the garage was occupied so I slipped into my in-law's master bedroom to use their bathroom when I became aware of the fact that I wasn't alone - my sister-in-law was half naked and getting her pussy eaten out by another woman. They freaked when I walked in on them, I barely recognized the other woman but she turned out to be my SIL's best friend and the two of them apparently had a thing going on that no one knew about, including their husbands. Now I'm no saint, but I never knew I could be a total bastard. I had no interest in the other woman at all and told her I wasn't going to say anything but I thought it'd be best if she left while I talked to my SIL. She bolted leaving my and my SIL staring at one another. She was about to ask me what I was going to say to her husband when I just pulled out my cock and told her to suck it.
Long story short, she sucked me off like a pro and I let her know that we weren't done. Before we left I made a date to "discuss things" with her later this week. I love my wife, but my sister-in-law is one hot piece of ass and I can't help thinking that it's worth the risk.
