My boyfriend's dad..
I'm 20 years old and three weeks ago my boyfriend of 8 months, Lachlan, left for a nine week trip to Europe to visit family. I had become pretty close with his father, Mark, in the past 8 months. The day Lachie left I was pretty upset, so his father said he would take me to the rent-a-movie store and we'd rent a couple good films to watch with him and his wife. We got back to his place and he received a call from his wife saying that she had met with a few friends from "college days" and she was going to the club to have a few drinks and she wouldn't make it home to the next morning. So we decided to put on a movie anyway. Mark had chosen a really romantic one for his wife and him. We pressed play and it started with a really hot, steamy s** scene. Mark and I were sitting next to each other on the sofa and he put his hand on my leg, moving up to my thigh and inner thigh. I didn't really know what to do, all I knew was that it felt so exhilerating! He started playing with my privates through my knickers and then moved to my b******. We were making out at this stage, he removed my shirt then my jeans. I took off his shirt and his jeans also. I then took off my bra and knickers and he started playing with my b****** and fingering me and eating me out. It felt so good! I sucked his c*** then I sat on him for a rough ride, we had sexy for such a long time and it felt so good! Best s** I have ever had! Every second night since then we have found an excuse to get together and have s** again. He wants to keep it a secret from his wife, but I feel so terrible. I want to break up with my Lachie for his dad. But I don't know how to, because Mark has a wife! Help me please!
