Still just in my shorts I dove in followed by the girls. For what ever reason the girl thought they would try and dunk me. Before I knew it the girls ...had attacked me pouncing on me like wild a****ls. I’m not exactly sure how but during the attack the girls had managed to get my shorts to fall off which wasn’t hard being just an elastic band gym type shorts. As I fished around for my shorts the girls were grabbing at me an still pouncing. The next thing I knew there were hands on my cock from. Penny felt the dog lift off and turn so it’s back legs were pressed against her ass. Laughing Julie said, “Now you are tied. Don’t move as you will hurt both yourself and Rex. I might as well fix myself a drink as you will be like that for the next 20 minutes.” With that Julie left the room leaving Penny locked in position. The knot was still pulsing inside of her and Penny could not resist rubbing her clit and she knelt there sending more min orgasms pulsing through her body. “Penny?”. After I had a drink I noticed a video camera on the floor next to John, I asked if he was going to make a movie of out actions, he said that he already had. He turned on the t v and there I was giving Larry a blowjob.Since there were 4 of us together for this party Bill suggested a gangbang for me as I was the only one that hadn’t experienced 3 guys at the same time. I was a little hesitant about this but soon agreed to try.The format for this was that Larry was going to fuck my ass while Bill. Now, understand, I was at a low point in my life. My job sucked. I was underpaid. I hadn't had a promising date in a year. So, maybe, yes, I was looking for something new, and different when I let him steer me upstairs to his studio apartment and pour me another drink. And yes, had I been sober, I probably would have reacted differently when he sat down right next to me on his couch. But I didn't. I took a swig of the whiskey on the rocks and looked him straight in the eyes, almost.
