A true story... 

We’d been on a river cruise. The boat docked and we got off the boat, probly the last to do so.  It was a warm summer’s evening and much as I wanted to get Deirdre and her gorgeous body back to the hotel and into bed, I also wanted to make the most of our one free evening together, so I suggested we take a stroll down the river bank. Hand in hand we walked for a short while. It was very quiet and there was no one else around. I stopped at a bench surrounded by trees near the river bank and sat down. I patted my lap and Deirdre sat on me. We cuddled and kissed and my hand slid under her blouse and fondled one of her 36B tits. After a short while she said we ought to get back to the hotel as we had an early start. She stood up and stood facing me, standing between my legs, her hand held out to pull me up. She was 5'8 in her bare feet and her heels made her taller so her crotch was at a perfect height for me. I ignored her hand and instead my own hand reached out and gently stroked the front of her long, slim leg through her skirt. She sighed and her eyes closed.  I carried on, gradually working my hand round to the inside of her thigh and moving higher and higher up her leg. She opened her eyes and looked at me and smiled and then her eyes closed again, so I carried on, slowly pushing her dress up as my hand went higher and longer. Deirdre still had her eyes closed so I slipped my hand under her skirt, and felt the cool, soft skin of her thigh. Slowly my hand worked its way further and further up and round to her inner thigh, until my hand was brushing against her damp panties. She was breathing heavily and there was no-one around, so my fingers started pushing up against her slit, through her panties, making them nice and wet. She was gently moving her hips up and down against my hand. I pushed the damp lace aside and slide my index finger deep into her pussy. She gasped and carried on moving her hips, rocking against me. I slid another finger in her. I was at the perfect angle to really penetrate deep into her pussy, and did, all the while being able to watch her reactions. With my left hand, I lifted up her skirt, so I could see my fingers sliding in and out of her soaking wet slit.

 It was twilight and we'd been like this for a few minutes, when I looked beyond Deirdre's pussy and behind her. Much to my surprise, I could see two young guys standing about 20 yards away. I'd been so engrossed in fingering Deirdre, I hadn't even noticed. My first reaction was to stop, but they were both looked to be in their mid teens, maybe even younger and were clearly no threat. Having a couple of young guys watching me finger fuck my girlfriend suddenly felt very horny. Deirdre still had her eyes shut and had no idea we had a couple of voyeurs.  It was pretty obvious what we were doing. Deirdre was moaning quietly as my fingers slid around inside her well lubricated pussy.  I decided to give the kids a bit of a treat. I’d bunched Deirdre's skirt up at the front with my free hand for my own viewing pleasure, but now I decided to lift it up at the back, to expose her very shapely ass to the two spectators, which I fondled with my left hand, squeezing her firm buttocks. I made sure I was now giving them a good view of her ass and black panties, while my right hand carried on making her juice flow. And flow it did. I could see the inside of her thighs glistening at the top. It was difficult to keep her skirt up though, so I gently tucked it at the front and back into the wide belt she was wearing around her waist. I don’t think she even noticed and certainly didn’t object. She was now quite nicely exposed to our spectators. My hand was free again, and I decided to give the teenagers an even better view.   I gently eased Deirdre around, turning her a little, so she was now side on to our spectators. She still had her eyes closed and was having a series of large and small orgasms. Positioning complete, I now had her at an angle almost side on to them and so they could see my hand going up and down as my fingers slid and sloshed around in her pussy juice deep in her cunt. My left hand moved up to her tit and fondled that through her blouse for a few minutes. I then undid a couple of buttons on her dress and slid her right tit out of its bra cup, tweaking her hard nipple and making her gasp with pleasure and pain. From where they stood, with her skirt up around her waist, so they could see everything from Deirdre's waist down, and no doubt her exposed tit. One of the guys moved round so he could get a better view of her ass I assume. Most of it was on show, although she didn't know that. I could tell Deirdre was close to one of those massive orgasms that women have that make their legs weak. So I took one very well lubricated finger out of her pussy and spread pussy juice and her creamy cum around her asshole. Once the lube was there, I slid that finger deep into her arse. She came almost immediately and almost collapsed down onto my hand, making my fingers go even deeper into both her pussy and her asshole, making her moan out loud. With that, the show was over and the two youngsters slipped quietly away, no doubt hard as rocks and would have a great story to tell at school the next day. I just smiled as one hand was still buried and the other was holding a very limp girlfriend up. Fun time over we strolled off and caught a cab back to the hotel. I never told her about our voyeurs and the treat I’d laid on for them using her shapely body. I get hard all the time thinking back to those 10-15 minutes of voyeur fun!
