I am not a writer but I am an avid reader of erotic stories. I tried to write a few non fiction stories based on my own weird fantasies but I could never finish them. Then I read some of the stories here and it gave me the idea of writing about true "incidents" that I was involved in. I found this a little easier as I only have to describe what actually happened to me in one event at a time. The following story is completely true and I hope you enjoy reading it. Constructive criticism (good or bad) is most welcome and appreciated.

My wife was in hospital after just having our first baby. I stayed with her until she fell asleep and then made my way home. I was horny as usual and phoned my mistress (calling her Emily) to arrange to pick her up on the way. Emily and I had been having an affair for a few years and used any opportunity to get together for sex.
I collected Emily and drove to my house where we immediately retired to the bedroom for a fucking session. It wasn't long before we were naked and enjoying each others bodies.
I love panty swapping so I had Emily wear a pink cotton panties belonging to my wife. (I love fucking a woman while she is wearing another woman's panties).
All was going great for a while, we were having our usual amazing (ten times better than the wife) sex. I was on top in the missionary position. Emily was gasping and groaning underneath me; her fingers were dug into my ass plunging me deep inside her as she pleasured herself on my prick. I knew she was about to cum and I was more than ready to join her.
Emily's body began to shudder and she soon began her usual gasping with "fuck me, I'm your whore" dirty talk. I replied calling her a slut and a bitch for fucking her friend's husband while she was wearing her friend's knickers.
The dirty talk pushed us to the edge and brought a loud gasp of pleasure from Emily. I knew she was "on the brink" as I felt her pussy clamp onto my prick. I felt my own raw lust build up and I was ready to shoot my load. I stroked faster and then felt the wondrous sensation of my cum shooting through my throbbing prick into Emily's pussy.
Emily's orgasm was almost instantaneous. She jerked her hips towards me and began to cry out loud coming hard and shuddering all over.
All I could think about was shoving my cock into her wet, tight pussy and filling it up with my cum. I was well past the point of no return when suddenly a light shone in from outside through the half open door.
The room became illuminated in bright light. My immediate thought was "my wife has come home". I watched in horror as the door fully opened and, as if in slow motion I saw, not my wife, but my wife's older sister poke her head inside. I could only stare at her as her expression changed from mildly curious to bad surprise and then just pure raw horror.
The sight that greeted her was one of confusion and naked bodies. The bed covers had long been kicked off so we were fully exposed when that light came on. I was desperately trying to withdraw from Emily's pussy even as my prick was still ejaculating my load. Emily was in the process of screaming out her first loud "ahhhhhhhhhhhh" while turning her head towards the door to see our unexpected visitor.
My brain felt on fire as contradicting commands were issued that my body and dick were in no position to carry out. I just could not stop coming. Emily was looking towards Mary but her gasping continued and I knew that she was also having trouble in stopping. She no longer screamed but couldn't help whimpering quietly as her body continued to orgasm
