The Older I Got I Realized She Did It On Purpose

My mom would almost always fall asleep while we were watching a late movie, she would also mix a few drinks or have wine some nights and sound really happy and playful. Most of her sleepwear was fairly short mid thigh sleep shirts or these long and short sleeve pajamas that were loose and flowing on her.
For my teenage hormone filled brain these were looked at as opportunities to look under and inside of and if she appeared out enough even touching. The older I got into my twenties I started thinking maybe she was not that out of it at all and just wanted to be played around with some. The farthest I went with exploring her was licking her pussy several times but never long enough to give her an orgasm, I did not even know how a woman had one at that time. I came on her one time and panicked so bad if she was not out she have been laughing inside barely able to contain herself listening to me get a wash cloth and wipe her off. I had played around between her breasts a bit too much and thought at the time it would fun to ejaculate doing it and it shot out so far it landed on her neck and face with the first few of them. I panicked but she knew what was coming if she was laying there knowing what was going on and listening to me. I can just imagine how often she probably laid there wondering how far I would go with her. I remember this one time where she had laid down on the couch wearing one of her night shirts, had one leg crossed over the other and bent up some, her ass and pussy were on display looking from her feet but when she laid down her head was towards my chair. When I got up and started looking from the other side she never moved at all, just laid there sleeping as I bent over looking very close at her pussy. Another thing she seemed to set up was her button up pajamas, almost never did the top two up so when she laid on her side the upper boob almost always ended up very exposed and a few times the nipple was showing before I even moved the top some. She never really would respond to being touched at all, maybe some murmurs as she rolled to a new position with me always thinking I lucked out because she was either more exposed or easier to get to her. I would be lost in the excitement of it not even thinking she was doing this on purpose.
