Happy Hour masturbation

Several years ago I went to happy hour with some friends from work 6 of us went 4 girls 2 guys there was sexual tension with me and 2 of the girls but at the time we were all in relationships. The conversation at the bar was about porn and sexual encounters needless to say this got mme extremely horny. I was asked what was the craziest thing I ever did and I made a lie about one of the girls Megan who was at the happy hour. I said remember the time we went to the gym after work then met up with some of your friends. She said yeah. Well after we worked out we showered she said yeah and.. Well before I showered I snuk into the womens locker room and watched you changed and jerked off to you. She laughed nervously and said really like 3 or 4 times. I said yep. She asked me what I saw I said just her ass as she walked into the shower. She then said I wish I knew I wouldve watched I said really? She said yep. As the night went on we drank more and I asked if she still wanted to watch me masturbate. She nodded her head up n down. My cock started to grow. She said when we leave follow me to my house my moms away for the weekend. Around midnight we left and I went back to her place. We sat in the living room she said she'd be right back. She came back wearing pajamas and had lube, a porn dvd and a glass dildo in her hand. I said I hope that's for you. She laughed and said of course. I was hard or semi hard the last hour anticipating it. I took off my pants and she said "not bad" and put the dvd in. Lezbo porn that's the porn she likes. I grabbed the lube. I started masturbating my heart was beating so fast and I felt like I was going to cum so I stopped. She said why u stopping I said because I'm going to cum and I don't want to yet. At that point she sat beside me pulled down her pants touched her pussy inserted her finger pulled it out and said look how wet I am. She then took off her shirt and she started playing with herself. I then began to play with her tits. I told her I wanted to see her great ass. She got on all 4s and started playing wirh herself with her fingers I resumed jerking off doing it very slowly so I didn't cum. I asked her if it would be ok if I came all over her ass. She said hell yeah. I got on my knees she remained on all 4s I got as close to her ass as possible it looked as if I pulled out of her from the doggy position that is how close I was. I said I was ready she said. Mmmm do it. So I did. It must have been the excitement but I shot several ropes that went up her back then I aimed it on her ass and showered her with it. As I was cuming she screamed I'm coming too and got pretty loud. I finished and she was still coming. I came a lot and shot it further than I normally do. It mustve been the excitement of the moment.
