I was taking a shower a few months ago, and didn't bother telling the family because they were asleep or watching tv. I hadn't really been thinking any erotic thoughts, I just wanted a wash. So you can imagine my surprise when my 14 year old brother walked in on me!
He just sorta stared at my 36c breasts, apologised, and left quickly. This shocked me a little, so for a few moments I carried on washing and a notion popped into my head. I did something very daring, and got out of the shower and walked down the hall to his bedroom, still butt naked. I opened the door and went in.
My brother was very shocked, he said 'What the hell are you..?' But I sat down next to him and noticed a bulge in his pants. I put my hand on the bulge and felt his breath quicken. I got on my knees and undid his pants and grabbed his cock, it was about 6 inches. I began to pump at it, waiting for the end result when he finally erupted, I sat back on his bed and asked him to do something for me.
I told him about a vibrator I'd kept a secret from everyone that I kept in my panty drawer, I told him to get it. He got the toy and I made him slowly push it in and out of my damp pussy, it was the most pleasurable experience of my life. We're hoping to do it again sometime, and I told him he can bring a friend.
