I was 24 at the time and had been with my long term girlfriend since we were 16, it was a great relationship and we were both extremely happy and affectionate towards one another. I had recently moved jobs and over the course of a year and a half i was slowly and deliberately seduced by one of my coworkers. For this story I will call her Sarah, she was lovely from day one and extremely friendly and asked me lots of questions about myself. Sarah who was 26 was about 5 foot 2 with blonde hair a curvy body, decent set of tits (around d cup) and a fat ass that was definitely noticeable from day one. I’ll be honest I may have rubbed a few ones out over her instagram photos which highlighted her cleavage and assets but not once in my life did I ever consider cheating. We built up a strong relationship fast and we began having inside jokes, spending more time together on our lunch breaks, messaging on snap chat out of work talking about life and my gf even met her at a work event and they hit it off. My girlfriend wasn’t able to make the work Christmas party which was fine as she had her own to attend. When I first noticed Sarah that night she looked stunning, she came running over and gave me a big hug and I instantly admired her cleavage which was on full display, she usually dresses pretty corporate so this was a welcome change. She was already pretty tipsy and we began drinking together and we decided to seperate from the crowd and sit down chat in private and that’s when she kissed me and at first I pushed her away and said I shouldn’t be doing this but then she put her hand on my leg and moved it close to my crotch as I felt my cock stiffen slightly. I was weak and I kissed her back and wanted to take her right there but it was to risky so we agreed to meet up at hers the next day under the guise that I was going to walk the lake after a big night drinking.

I drove to Sarah’s house and felt physically sick with what I was doing and thinking off. I knocked and Sarah open the door slightly as I walked in, she had a dressing gown over and instantly kissed me and told me she wanted to show me something. We went to her room and she commanded me to sit at the edge of the bed as she took off her gown exposing her perfect body in all its glory covered by a dark lingerie that looked great with her skin tone and hair. My cock began to harden as she approached and sat on my lap and kissed me passionately as I ran my hands through her hair and occasionally stopped her to kiss along her neck up to her ear. She stopped and span around and stopped facing her ass to me as I slapped it and she exclaimed “ I bet your girlfriend doesn’t look this good in lingerie” my girlfriend is slightly larger and never wears lingerie.

I’ll add a side note here to mention that Sarah had previously spoken to me about my relationship and would ask lots of questions and always side with me when I mentioned little arguments I had with my gf. She would also talk about all these crazy stories she had.

Back to the point. I grabbed her ass and squeeze it as I pulled her onto my lap as she started grinding over my sweat pants as I ran my hands along her curves up to her boobs (these tits we’re amazing) and I made sure to squeeze them as Sarah purred with excitement. She got up turned around and pushed me back onto the bed as she climbed on top and our lips met and we kissed passionately for what felt like an eternity as I got more and more turned on. Sarah knew this and got up and started taking off my clothes as she stopped occasionally to run her tongue over my body. She slid off my underwear and my cock stood there erect and ready for her. She put one hand on it and slowly stroked it as she came closer to kiss me and slowly started to speed up her tugs as I groaned. “ do you like that baby?” She said in a soft voice as I nodded and ran my hands over her body. I stopped her and got up as I took off her lingerie which was actually tough work! And I began to kiss her body over and then started to kiss her right nipple as I pinched and poked her left as her breathing become slower and she let out little moans, I buried my face between them and only stopped for air and to kiss her. I then went back to the right nipple as I ran my finger down her body tracing her stomach and slowly around the walls of her pussy. I slowly pressed my finger ever so slightly against her clit which was soaking and I slowly began to brush it gently as she moaned softly. As I began to speed up I kissed her and took pleasure in her moaning. I would tease her hole as well slightly putting my fingers in. This went on for quite some time and she began to get wetter and wetter until her breathing sped up and she moaned my name as I went down and began to twirl my tongue around her pussy and softly started to suck her clit, within a few moments she was cumming hard and I savoured every last drop of her as she moaning my name. After she came I got up and kissed her and she told me it was my turn as she started sucking my cock and boy I tell you this was the best head I’ve ever had in my life. She was slobbering all over my cock and I could feel it twitching in her mouth responding to every slight lick. She got up and climbed on top and positioned her pussy just above my cock and without warning she slowly engulfed my cock into her tight pussy which felt like pure ecstasy as she slowly rode me as we kissed. She sped up and that’s when I remembered I should have had a condom I wasn’t thinking properly but I was too horny to deny this feeling. With each moan of Sarah and her pussy grinding on my cock I got closer and closer. She asked me if her pussy was better then (girlfriend’s name) and told her yes as I began to thrust into her and she let out a gasp. I began to speed my thrusts as I moaned her name and she encouraged me go harder as she squealed with pleasure. I was past the point of no return and told her I was going to cum and she took control and sped up saying “come on, show me how much you love this pussy” I moaned loudly as my cock throbbed and shot a load deep inside her pussy as we started kissing and slowly slowed her speed as she milked every last drop. We kissed, laughed and had a bit of pillow talk and then parted ways. I felt a huge amount of guilt but also a sense of relief. We continued to meet up over the course of the year and eventually got together as i had came clean to my gf and till this day Sarah and i are still together going strong. we went about it the wrong way and we both regret what we did but also happy now. have plenty more stories if you want to hear
