For many years now, whenever she visits, I've been setting it up so that my sis in law would catch me jacking off. It's incredibly hot, to say the least. The first time was a bit bumpy, but has lead to some great fun...
I'd had the hots for her for years and there were a few times she'd accidentally walk in on me as I was changing. We'd both be shocked and embarrassed, but also laugh afterwards. There were also times I'd have to go to the bathroom while she was showering, or visa versa. Always loved seeing her outline through the shower curtain. After a while I'd get bold and pretend I forgot she was there (while I was in the shower) and quickly shut it off and pull the curtain back while,she was still sitting there. Little games like that...
Then I got the idea of letting her catch me jacking and tried to set something up. 3, 4, 5 times I'd try and fail. She'd either not walk in, as I expected, or I'd chicken out at the last second... sometime leave the door open hoping she'd glance in, but never did, etc...
Then it happened... she was doing laundry and I knew she'd be putting it away shortly so I got in bed and started jacking, with the door open about a foot. Suddenly I heard her walking down the hall and knew this was the moment of truth...
DAMN! She just stopped at the end of the hall (I had full view of her and if she'd have looked, she'd have seen me) and she set the clothes on a shelf at the end of the hall instead of bringing them in. I damn near blew my load! She was done and walked back to the living room, having never seen me. I was bummed, frustrated and horny as hell. Kept stroking and decided, in my cum muddled head, to go for it...
So I called to her! (Fake names here...). I said "hey Betty!, come here for a minute!" She holered back "what?" I just said "come here for a second!". Still stroking I could hear her walk back down the hall and she walked right in. I had started cumming as I heard her foot steps and was still shooting when she walked in. She said "oh billy! Jeeze!" Turned and left.
I was scared to death but fully relieved. I cleaned up and went out. She was silent so I broke the ice with a heart felt apology and she said "well, don't do that again!"
Yeah, that didn't work... LOL. Now that the ice was broken it really got into it
Hope you enjoy!
