I personally am not into watersports, but since I am into pleasing men no matter what their fetish is, I have had a very experience with that! It was a couple of years ago, when I was at a bar and strutting around in four inch heeled ankle boots, a short black low cut dress, and sheer stockings with no panties. Two guys came on to me and the next thing I knew, we ended up at their motel room.
I had drunk a lot and really had to pee, and they kept getting turned on by that and prevented me from getting to the bathroom. Finally I told them I was about to pee in my stockings, and that got them extremely excited and they pulled my dress off me. Both of them held me and kept me from going to the bathroom, and they told me to go ahead and pee.
I was drunk, and I really had to go, so I started and it flowed all down my hose into my boots; little bits splashing out, but mostly warm piss filling my pantyhose, gathering in a pool around my cunt and ass. The warmth and how turned on the guys became really got me excited, and I was wet in more ways than one.
They had been fondling and teasing me, but now they had their pants down and their cocks out. They told me to get on my knees and suck each of them off. I kneeled, making a wet spot on the floor, and went to work on the first guy's cock. He pulled out and came on my face, but before I could try to wipe it off, the other guy had shoved his cock in my mouth. I started sucking, deep and fast, and soon he came, also pulling out and shooting it all over my face.
