This happened to me about five years ago, but it's not the kind of thing you forget. Sofia and I had gone to one of our parking spots overlooking the city of X. (in Europe, as you'll see), but it was a warm, even sultry night, so we got out of the car to get some air. There was half a moon behind thin clouds. I pinned Sofia against the side of the car and kissed her, and pressed my hand to her breast. Another car drove up. That wouldn't necessarily have stopped us, but we decided to go for a walk in the woodsy park nearby. We had walked there once in the day, and we knew there was a cute little gazebo in a secluded spot not too far away.
There were two other couples there, 20-somethings (we're in our 30s), maybe double dating, though not sitting side by side. The gazebo was hexagonal, with wooden benches and railings. We took a place in the empty third, equidistant from the others; we said a quiet hello. The others had been chatting and perhaps making out; the men had their arms around the women's shoulders, but everyone still had all their clothes on. Sofia and I talked softly, in English, about nothing in particular, just to get the feel of the situation. The other couples started kissing, and that was good enough for us. We did the same, but we knew we were being watched, which (as always) excited us. Soon my hand slipped off a shoulder to cup a breast, and slowly fondled and pressed and caressed it through Sofia's t-shirt.
Did I mention that it was a lycra t-shirt with a provocative series of (designer) holes in it, worn without a bra? And that Sofia has beautiful full breasts? The men must have seen me stroking those shapely titties, and I just loved pushing them around through the lycra and sometimes lining my fingers up with the holes for a feel of skin. I could feel Sofia's nipples become erect, and I knew they could be seen clearly poking against the stretchy fabric in the half-moonlight. I was turning Sofia on -- I could tell by the pressure of her kisses and the way she leaned her head back and raised her chest to me -- and I slipped a hand under her t-shirt until I had a breast full in my fingers. The feel of that hard nipple made my cock throb. Sofia read my mind and put her hand over my cock, hard as a bone inside my jeans (for convenience sake, I was going commando).
I stole a look at the other couples. The girls had their eyes closed, but the guys were watching us. I smiled at them. They both started stroking their girls' breasts as I watched. That made the girls open their eyes (and I looked away, but I knew the girls would see what I was doing to Sofia). Knowing I had an audience, I dropped my fondling hand and began to raise Sofia's t-shirt. That made her take notice. She saw that the others were making out too, and I knew what she wanted. In moments I was sucking one, then both nipples and then kissing her on the throat so the other couples could her a good look at her heaving chest, at those beautiful tits and those fully erect nipples, just glistening a little from my sucking. I knew that the guys would be feasting on the sight.
Sofia surprised me by suddenly swinging a leg over mine and straddling me and kissing me hard, her t-shirt still rolled up over her tits. She was wearing a thong and a loose, pleated skirt. I could feel the heat from her crotch right on top of the bulge in my pants: the lap dancer's pose. I held her by the shoulders and buried my head in her breasts, sucking her nipples to my heart's content and (I knew) sending her into a zone of no return.
I dropped my hands to her ass and slowly and deliberately gathered up the fabric of her skirt. I could look over her shoulder at the other couples. One girl's blouse was all unbuttoned and her bra was raised and her tits were being pawed. The other girl was stroking her boyfriend's pants as her rubbed her between the legs through her shorts.
