I'm taking this to my grave, but I need to vent it somehow so here it goes, last week I had sex with my best friends wife. I've never thought of her sexually before that evening. My best friend of 15 years was out of town for a weekend work trip, his wife, Carrie, called me and said her car broke down and asked if i could come pick her up from the repair shop. I picked her up and drove her home. She invited me in and we hung out for a bit. We had always been chummy and had hung out on our own a few times. She went to change and I grabbed a beer from the kitchen. She came down wearing yoga pants and a plain t shirt, nothing revealing. She is very pretty and over weight, I'd guess about 200 lbs. I was never attracted to her before but seeing how comfortable she was around me was a turn-on i guess. I sat on the couch and she sat beside me, we chatted for about half an hour before the subject turned to sex.She asked how my girlfriend was and i mentioned that we had been going through a rough patch and we hadnt had sex in a while. She said that if I was her boyfriend no matter how mad she was she would still fuck me. I didnt know what to say, I just smiled and sipped my beer. If felt a little awkward for a moment and we just stared at each other. She moved closer to me and began to touch my leg, she thanked me for picking her up and said that she knew I would come through for her. I knew what I wanted to do and I knew how wrong it was, but I was completly possesed by lust. I put my beer down on the table and kissed her. The moment our lips touched we were all over each other. Our tounges were lashing in each others mouths like we were teenagers. I gropped her big tits and they felt amazing. Very big, but so soft and firm. She rubbed my boner through my pants and I slid my hand down hers. My fingers flowed through her bush, she had a very hairy pussy but her lips were shaved. I began to finger her and she was already wet. I rubbed her clit for a while and then slid my index and middle finger inside her and worked her G spot. The way she moaned got me so horny. I could feel myself pre-cumming.I got up and pulled her pants and panties off in one shot. The second her leg was free of her pants she spread her legs and showed me her lubed up pussy.I kept fingering her G pot and started to lick her clit. She tasted so sweet. With my free hand I un-did my pants and took my cock out and began to stoke it.She bucked her hips into my face and I kept going, her pussy juice was running down my chin. She let out a cry and pushed me away. She came all over my face, and closed her legs and turned on her side. She kept saying "oh my god...oh my god..." But i was rock hard and wasnt finished. I rolled her over and spread her thick ass cheeks, I had never done this before, but when I saw her asshole shining with cum i shoved my face right into it and licked it and stuck my tounge up it. She was quivering and shaking her face was burying in the couch and she kept whispering "thats my asshole, thats my asshole". I didnt care it tasted so good. All of my perverted demons were coming out with her. I pulled my head up and stared at her big white ass. For years I had always practiced safe sex, but today I didnt give a fuck. I gripped my cock under the head and slid in the tip, she moaned and I knew that it was actually happening. I gripped her chubby hips and began to pound her. I had never had sex bareback before and it was euphoric. I felt dizzy and was seeing stars. Her ass cheeks rippled every time my pelvis made contact. I was in a trance. She was screaming and it sounded like she was speaking tounges, repeating "im cumming im cumming im cumming im cumming" over and over again. She arched her back and pulled her shirt off. I unhooked her bra and she tore that off too. I reached around and squeezed her tits so hard. I had to see her tits, I pulled out and she rolled over and I went right back inside of her. I was on top of her thrusting so fast. Her fat stomach and huge tits swayed with out fucking. She was so soft and warm. I could feel myself reaching orgasm and I wasnt going to stop. I felt myself begining to cum so I shoved my rock hard penis balls deep inside her. Feeling my semen splash inside was the best orgasm id ever had. I collapsed on top of her and kissed and sucked her breasts. After a few minutes I got off her sat on the couch, both of us naked just sitting in silence. After what seemed like forever, she said "id wanted that for a while. But it wont happen again and no one can know." I agreed, but I looked at her big tits and got horny again. I said, "I would still like to know how you suck dick'. She smirked and sat up reached over and began to slowly stoke me till I was hard again. Once I was erected, she leaned over and started blowing me. I reached behind her and rubbed my finger tip along her asshole and slowly stuck it in. Her head was bobbing so fast and the slurping noises were so fucking hot. My dick started tingling and I was getting ready to cum. I knew this was never going to happen again so I stood up and began jacking off in front of her. I didnt have to say a word, she knew what I wanted to do. She pulled her hair back, closed her eyes and put her face forward. I started to cum. The first shot splattered across her nose then on her forhead. She took me in her mouth and I finished blowing in there. She sucked me till I was too sensitive and pulled back. I sat back on the couch and she wiped my cum off her face with her t shirt. She got up and said "not a word", she walked upstairs and I could hear the shower turn on. I pulled up my pants, chugged the rest of my warm beer and left.
