This only happened the other day! I'm glad to share it with other people, as danger of getting caught is a huge turnon!
Just two days ago my family was having a BIG BBQ, as we do once or twice a month. The whole deal with chips dip hotdogs and steaks (we forgo hamburgers) and friends. My aunt had brought her boyfriend and her two children from her marriage over, and they are only nine and eleven.
Well my boyfriend was over... call him A, and after eating, the family decided to watch a movie. It was one I know that he doesn't really like, so I suggested we go into the game room (just an extension of our living room) and watch a different movie. We were totally visible, but with our backs to the other room when he decided to sit behind me. Thinking that he was just being cuddly, I let him. Usually I don't really like being all touchy-feely when my family is around. I hate getting teased and stared at. But that's not all he wanted. I could feel his hard-on pressing into my back, so to tease him I kind of wriggled, pressing my bum more firmly against him. I was rewarded with his hands coming up to cup my 34-b sized breasts. He's a little inexperienced and this is the first time he's ever used both hands- it was pretty awesome.
I could hear my family in the other room talking loudly, and every once in a while my cousins would wander in, and he would assume a more casual position. And through it all, his hands kept up their venture, messaging and squeezing my breasts and playing with my nipples. Soon he did something very bold, he's never done it when there's a chance of getting caught, he started to finger my by now very hot, wet pussy. I had to bite my tongue to keep from moaning, as this was much more intense behavior than usual from him. He was slightly rocking his body against mine, almost invisible, but I could feel it and it was Wonderful!
I didn't get to cum, but with him doing that to me and the chance of my family catching me in the act was almost enough. For him too! I couldn't even wait for everyone to go to bed to get myself off that night. I waited for my aunt to take my cousins home then went to my room and played with my self for only moments before I came, panting into my pillow.
