Mistake

My fiancee had called me. It was 11 pm. I was half asleep when I answered. Her bff from work had broken up with her boyfriend and for weeks had been acting crazy. She was drunk and wanted to drive 4 hours to see her ex. My fiancee asked if I could go check on her. I knew her bff before she did. We were friends but nothing more. When I got to her house the place was a mess. I found her digging through the couch cushions looking for her key. I spotted them and put them in my pocket. I got her to calm down. I straightened out the couch so she could sit. After a minute she started crying I sat next to her and and comforted her. She was ask me if she was attractive. I told her she was. At that point she tried kissing me. I refused and got up I continue to straighten out her living room.
I made food so that she has something in her stomach best the liquor. I sat to smoke a joint while food cooked. I was smoking and she asked for a puff. I passed it to her. After eating we were watching a movie. My fiancee called me I explained everything was going good. She was still worried. I don't know what her bff told her but it hard her scared. I assured her I was there and it was fine. My fiancee was practically begging for me to stay at her friends. Sho told me she would meet us in the am. I reluctantly agreed. I went to sit on the couch. We smoked some more. She had said she was going to change into her pajamas. Where she returns she had on these tiny. Silk shorts. And matching silk top. She sat next to me when she layed on the couch she folder her knees up a little. Her body leaned on the corner of couch. She was eating snacks. I noticed that with her legs bent you could see that she wasn't wearing and panties. When I looked at her chest the top was loose and I was seeing underboob.
I did my best to ignore her but she would move a bit and the views would get better. I decided to smoke again I rolled a blunt this time and she wanted some. She moved extra close. We were smoked. We were talking and laughing. I was blowing smoke rings. At one point I had a mouth full of smoke ready to make rings. She leaned in and got inches from my face. She started sucking the smoke from my mouth into hers. She asked if I wanted to suck the smoke out of hers I refused. She took a puff and got real close. I could smell her mint lipgloss. I opened my mouth and started to suck. The smoke went from her mouth into mine. As I exhale. She told me that see it wasn't so bad and she didn't bite. I'll admit I popped a chubby. I had to hide it.
When she fell asleep she extended her legs. I let her rest them on my lap. She was asleep so I called my fiancee let her know everything was good. She was telling how amazing I was. And how she would take care of me later. We started flirting a little bit. She was telling me if we were home all the nasty things we'd be doing. As her friend started to toss and turn her clothes were riding up. At one point half her short were in her ass . Her tits were both out. With my fiancee talking nasty to me and her bff practically naked in front of me I started masturbating. Her bff layed on her back her tits were still out and her pussy was eating her shorts. I could see that her friend was usually shaved but the stubble was growing in. My fiancee had to get back to work. Her friend was still half naked in front of me I was still hard. I imagined slowly sliding my cock into her friend pussy. But I didn't. I stopped masturbating and decided to just fall asleep.
I was sleeping when I felt my basketball shorts getting pulled down I was a little out of it. Before I could say anything her friend had me in her mouth. I half heartdly said no. I was trying to say no but all I could do was moan. I leaned my head back. I felt her stop. When I opened my eyes she was lowering herself onto my cock. She pulled her silk shorts to the side. Her pussy was warm. It felt amazing. She must have been wet because I slid right in. She was bouncing up and down her tits in my face. I started leaving her hickeys on her tits. She told me she had opened her eyes and had caught me masturbating. That all I had to do was ask. She was grinding on me. She started asking who's pussy was better hers or my fiancee. I told that my fiancee was better and she started grinding faster and harder. She asked and and I gave the same answer. She added a circle of her hips to the grinding and bouncing when she ask again I couldn't answer. I had cum inside her. She sat on top of me my cock inside her. She put her arms around my neck. We stayed like that till I got soft and slipped out of her. We finished just in time my fiancee had just pulled up.
As far as I know my fiancee doesn't know. I'm worried her friend will tell her. I regret it but to late now.
