[str8-M] [f]
A year or so ago I was staying with my brother at his place, (he has a wife and 4 kids, 3m, 1f)
The night before this happened, after everyone was in bed, I was up late, I was kinda horny, so I got into my latex underwear, and took an erection pill (not viagra). I had been edging alot during the night, and I had a rough time sleeping. I know he and his wife got up early and headed to work, and the kids like to sleep in, I felt I was safe enough to go sit in the living room, and edge more by rubbing myself through my latex, which with the erection pill as soon as I got hard and was rubbing, I got about 4 edges in and was resting before the starting of the 5th. I figured with all of last night and 4 this morning, I could just unload all of them into my latex and shower later, I got to going pretty good and just as I was about to start bucking my hips to get a deeper rub, I heard a creak on the stairs, and here I am now at just about to blow, I rest my hips, and put my arm down to kinda cover my standing and throbbing erection and it’s going into the point of no return, I turn and look to see my niece coming up the stairs. I let my arm drop right on top of my swollen, sensitive shaft, just as she was walking by I burst, and went into pump mode, I was hoping she didn’t notice that my sweat pants were bobbing and throbbing, to me it looked like she was looking toward the kitchen, as she went in got her cereal, I was throbbing, and pumping the whole time trying hard not to moan, and grunt with the hard pumping, I let out a small breath just before she walked back by and back down the stairs. I was shocked, excited by the whole encounter. Nothing was said, so I have no idea if she even knew what I was doing, or what happened. For me, that was the longest and hardest orgasm I’d ever had, I’ll be more careful next time I’m visiting when I get horny like that.
