This is my first story. It's not as juicy as some but I like to remember it & jerk-off.
I was away for the weekend with my wife at the time & her friend Nancy. We got a motel room with a bed & pullout couch. We slept on the pullout. I stripped nude after the lights were off. There was some joking about sex & then we all went to sleep. There was enough light showing through the windows to see. I stayed awake with an erection wanting to jerk-off. I was about 26 at the time with never ending erections.
I got a sexy idea & slowly moved all the blankets off me to show my then very fit body & long hard cock laying back on my belly. A while later Nancy got up to use the bathroom & I never moved. She got a full view coming back to the bed. My cock was hard & as stiff as it could be. When she laid back down she was turned looking directly my way & never moved. I couldn't see if her eyes were open or not but I'm sure they were.
My wife was still asleep so I took my cock in hand, held it straight up so Nancy could get a good look & ever so slowly slid my short cut foreskin up & down for her to watch. She never moved.
Within about five minutes of very slow jerking-off I felt the inevitable about to happen. I tried my best to keep my breathing quiet while my load shot into the air & back onto my body. It took so much effort not to move when I came. My body usually bounces around during orgasm.
I laid in cum for a while then I got up, took my pants for cover & walked to the bathroom to clean off. When I got back Nancy was facing the other way. Still to this day I don't know for sure if she watched me but I believe she did.
Now that I'm not married to the same woman I suppose I could ask her. Maybe next time we're out in a group with a few drinks. She'd be more open then.
