I recently discovered this wonderful site! I want to share an experience that happened last year.
My wife has an unmarried girlfriend who visits us often. The girls are always talking about using their vibrators and joking around with me about it. One afternoon on a Saturday we were cutting up and talking in the living room and my wife told her friend how much I liked to watch her use her vibrator and how I loved to jack myself off while watching. Her friend squealed with delight upon hearing that. I was laughing too and I said what the heck, I loved to masturbate as much as they do and I saw nothing wrong with it.
My wife added that I did it often and she liked watching me do it. About now, her friend said she loved to watch guys masturbate too. My wife jokingly said I would probably do it for them if I were asked! I was laughing and said 'Yeah, anytime, any place!'
My wife's friend said 'OK, how about right now!' I asked if she was serious and she said 'Yes! I'm serious.' I looked at my wife for some direction. Should I really or is she kidding, I was asking myself? My wife smiled at me and said 'Go ahead and do it!'
I sat there getting hard at the thought. I said 'OK ... here goes!' I started rubbing my growing bulge through my jeans as they intently sat watching. My wife finally said 'Stand up! You are going to take forever!' I stood and she came over and unbuckled me and unzipped me and pulled my pants down to my ankles. I kicked off my pants and underwear and now stood in front of them both with what felt like the biggest and hardest erection I've ever had.
My wife and her friend sat there with big silly grins on their faces as they admired my hard-on. I didn't know whether to stand or sit. I sat back down on the couch and my wife sat on one side and her friend sat on my other side, each resting their heads against my shoulders. I leaned back and stretched out my dick so they could easily see my full length and thickness. Her friend was making a bunch of great comments which really had me turned on even more.
I began slowly stroking my super hard dick telling them how excited it was making me to share this with TWO women at the same time ... and I was saying naughty things like how I wanted to lick and suck both their pussies. I eventually talked them both into getting naked and sitting back down beside me. I could hardly contain myself. Both of the girls were rubbing their clits and fingering themselves as I stroked myself. It was the first time I had ever seen my wife's friend's great body, and she has a beautiful tasty looking pussy and nice breasts and large well formed nipples.
Together the three of us sat there masturbating, legs sprawled wide open, watching each other. I was the first to lose it. I knew I was about to blow my load so I told them then leaned way back as I came squirting loads of hot white cum all over my lower stomach. My wife's friend went crazy fingering and rubbing herself when she saw that and she came shortly afterwards followed almost immediately by my wife.
That was so hot. She has been back over to visit many times since and I've all but begged for a repeat performance but they just laugh and say 'Been there, done that.' I guess it won't ever happen again, but almost every time I jack off now I fantasize about this one experience. It was probably the most exciting thing I've ever done in my 48 years.
