Mum had been deserted by my asshole of a father....who, incidentally, I know used to use my panties to whack off into. Then, mum had an accident and needed help to bathe....
She could not reach her back or legs, so I used to wash her. Usually, this was in the bath, but this time, for the first time since the accident, she wanted a shower.
This meant I had to get in with her. No big deal...I needed a shower too. Mum had her back to me and I was washing her as usual. Her back, down her legs, then back up the from of her legs. I was standing behind her, and my hands reached her upper thighs. Mum moved, and my hand slipped between her legs. I could feel how wet she was, and it sure as shit wasn't water from the shower.
For a second I froze. Then I realized....dad left... No sex...and now since the accident, no masturbation for her either. Shit, it had been well over four months! If I go four hours without a cum I get cranky. So I moved my finger. Her lips were already swollen and parted so I found her clit. Mum moaned and leaned back against me. I let my finger find her hole and slip inside. Mum started to grind and get really into it. I rubbed her ass with the other hand and let my finger slip into her tight asshole. Suddenly, I felt her hand reach back and went between my legs and inside me. It was so fucking erotic. Mum was fingering me, I was doing her. Then. I felt her cum...and by crap....WHAT a cum! Long, hard. Violent, and wet. I came when I felt her pee into my hand.
After, there was no embarrassment. Mum didn't know I shaved, and wanted me to shave her. This led to me bringing her off again in the shower. Again, when she came, she squirted, but not pee this time. This time it was pure girl cum and I got a face full.
Since then, mum and I have done much much more than just masturbate each other. I have a boyfriend, and one time, mum wanted to fool around the moment I got home. Unfortunately, what she didn't know was that he had just fucked me up against the wall of the house, and I was full of his sperm. There was nothing to do but fess up.
It didn't stop us though. Mum wanted me to tell her exactly what we did to each other, what we said, and how we did it. Then, she slipped her hand into my panties and inside me, drawing out her sperm soaked fingers, she licked them as I made her cum...this was the first sperm she had for a long, long time.
I love what we do... Mum and me... It's kinky...dirty...forbidden. That's why I like it. Mum asked me if I let my boyfriend fuck me up my ass. I've thought about it, but haven't yet. Mum says she used to love anal, and then using her fingers, showed me how great having something in your ass feels. My boyfriend has a treat coming!
I've been thinking though....as mum isn't going to recover any more movement, maybe I should see if my boyfriend will be up for helping her out? I think she misses a cock.
