I [f] walked in on my married friend being plowed by a stranger..

The past year or so ive become best friends with a woman who owns and runs a small gym.

K is a pilates instructor and personal trainer so she has everything I’ve needed to help keep myself in shape. After a few months we opened up to each other and got drunk spilling our deepest secrets and she told me shes in an open marriage and regularly slept with other men that her husband didn’t know about..

I was a little shocked to begin with because she was the picture of a perfect housewife. Tall, blonde, nice firm tits and an ass that would make a grown man cry… she was in a word a perfect young 29yr old milf… we kept becoming fast friends untill she was comfortable enough to give me a key to her gym so I could work out whenever I wanted even after hours.

The gym was in a perfect location only 10 minutes from work on my way home so after shifts id be able to stop in and do a quick work out before home I started using it more and more letting there after dark, doing an hour then leaving and it was no diffrent on Friday night..

Id changed into my workout clothes at the hospital and was heading into the gym when I heard the unmistakable sound of flesh on flesh echoing from Ks office. I stop and think about leaving but my horniness gets the better of me and leads me into the wide open door way when I find K being bent over a desk being absolutely destroyed by a man clearly not her husband.

He has a handful of her long blonde hair pushing her face into the desk as a very nice cock strokes back and forth, raw, into her perfectly waxed pussy. I stare, transfixed by the situation untill he senses a presence in the door and turns.

He doesn’t even flinch, just keeps on pumping into my friend as he looks me up and down and turns Ks face towards me so she can see. “Looks like we have a little visitor K” I look down at my friend who smiles the smile of a well fucksd woman and just simply says “hi, don’t mind us you can watch or enjoy your workout”.

I try and stammer a response but I’m still a bit shocked as he lifts her up and falls back into a chair behind the desk…”let the poor girl workout K” her mysterious suitor responds as she now starts to ride him slowly. I watch her natural tits rhythmically sway as she works him deep inside her and just gives me a smile.

I slowly walk away clearly hearing how wet she is and the moans still echoing from the room as I begin my work out. Looking back from time to time, catching glimpses of the diffrent positions they are trying out.

Eventually the big finish happens and things go quiet for a few minutes then the mystery dick walks out of the gym and gone down the st.

I go and find K with her head hanging over the edge of her desk looking up at me and just happily asking how my workout is going and thst I shouldn’t be afraid to join them next time…

I really do love my life..

Love your friendly nurse.
