Oh, No! Oh, Yes! - Part 3

Finally. It's been over a year now since I accidentally sent my sister-in-law the email that was supposed to go to my wife. Who knew, as I sat there in a panic at the time wondering what to do, that it would lead up to these encounters. So far my sister-in-law and I have been able to play together on two occasions since my initial accident of hitting the send button. Since our last encounter our families did get together once but we were unable to make anything happen. It was a quick visit and the timing of everything just wasn't right. As usual we never want to force anything if the situation isn't there. Or at least that's what we tell ourselves. This third visit I'm about to share with you was by far our most intense. We agreed not to have sex. At least that was the plan. Yes, we could just get a room and have complete privacy to ourselves without anybody walking in on us. But honestly, what fun would that be? The best part of a cat's life is chasing the mouse. If the cat can have the mouse any time it chooses, then the cat will no longer crave that mouse. Well, about two weeks ago my wife tells me she wants us to go up to visit her sister and her kids for the weekend. It's been a while since our families have gotten together so sure, I'm up for it (no pun intended). Also... they have a hot tub! As usual before our visits, I send my sis-in-law over an instant message while I'm at work telling her that I'm looking forward to the visit. She replied back happily and this ...

... begins an instant message marathon over the next three days that blew me away. Basically, we started off with polite small talk and gradually escalated to full on dirty talk about what we wanted to do to each other. Most of the stuff we wouldn't or couldn't actually do, but for three days while we were both at work, we talked and masturbated over instant messenger. It was simply amazing listening to my wife's sister, who in our family settings is very conservative and clean cut, tell me things like she wants me to finger her ass while she sucks on my cock. It's fascinating seeing another side of a person come out when the right situation presents itself. We halted our messaging a couple days before the visit and where we left off is where I hoped to begin. I told her I wanted to cum for her as many times as possible over the course of the weekend. Who knew if we would have time for 10 minutes of privacy like our last session in my kitchen or if it was going to be nothing but quickie encounters of her watching? I didn't know and I didn't care. This was as open and dirty as we've ever been with each other online, we were both horny as hell and I was excited to see where it would go. I also asked one last favor of her. For some reason I'm always paranoid that even though we have our fun online, when it comes time for our actual family visits I'm worried she may have a change of heart. Which is perfectly fine, but I don't want to be persistent and make her uncomfortable if she ever ...
