Lin grabbed hold of my cock which was not hard and started to pull and tug on it saying that I cant get a girl I just have to wank over her dirty pant...ies instead. I thought it could not get any worse but then my cock started to get hard with it being wrapped in Lin's hand. As soon as Lin realised this she started with another tirade of abuse calling me a sick bastard as I getting aroused over my own cousin grabbing my cock.From the position Lin was in, straddling me with her legs open and her. We made love slowly and fell asleep in each other’s arms.When Bethany and I woke in the morning, we made love again, then showered together. We had breakfast in the hotel restaurant, then checked out and headed to my house to pick up my little sister.Stephanie had helpfully put together a box with cleaning supplies and was sitting in the living room waiting for us. She saw the car and came bounding out of the house with the box. Bethany got out of the car and let Stephanie get into the back. I told her everything Mike had said, in detail. She told me she had suspected something for a while as he had stopped flirting with her and the other women some time ago. I had never noticed. Tiffany had confided in her a month ago.Tiffany came to us and handed me the phone again. I listened to Mike as he assured me things were going to be good and that he was grateful that Pam and I understood. I asked him if he wanted to come over. "No. This is between you and Tiffany. I don't need to know. His cock was now bigger than ever. He started kissing me again and whispered in my ear, "do you like doggy honey"? I said " I love doggy baby"! When I got up on all fours for him to mount me I noticed a couple of guys not to far away jacking off and watching us the entire time. At this point I didn't care, I was feeling like a slut and whore, I would have fucked them too I was so horny. I spread my legs and he started by sliding his big hard cock all over my ass and slapping my ass with his.
