We have a whole house full of people on Friday night and realized early evening we needed a couple of things from the grocery store. I told my wife I’d run out and my sister in law said she’d come with me. No she is really fucking hot, great body and incredible tits. Anyway we left and I headed into town when she told me to pull over into this empty parking lot. I asked why and she said just pull over. I thought she wasn’t feeling good or something so I did. I parked up and she took off her seatbelt and leaned over and began kissing me. Now to be clear, nothing has ever happened between us before but I was really enjoying it. She took my hand and placed it on her leg and moved it up to her pussy. She was very wet and I began rubbing her. She was moaning and told me to finger her. She opened her legs as wide as she could and my finger went easily inside. I fingered her till she came like an express train. My finger was soaked in her juices. By now my cock was harder than ever and sticking up in my jeans. She was feeling me and told me to get it out. I unzipped and got it out. She said she couldn’t believe how big I was and how lucky my wife is to have it. With that, she bent over and started to suck me. It was so good I knew I wasn’t going to last long and I warned her I was going to explode but she kept on sucking until I shot a massive load in her mouth. She kept on sucking and swallowed every drop unlike my wife who doesn’t even like giving head. After I came she continued playing with my cock as it got soft telling me how big it was and how she wanted to feel me inside her. I said we better get the stuff from the store and she agreed but said she wants to meet up and for me to fuck her.
Now I don’t know what to do as I’ve never been unfaithful to my wife but I really want to fuck her. I need to figure this out.
