Moms slip up

I had a slip up, im a mother (40f) with a son (18m) one day i was masturbating thinking that my son was playing one of his video games but he heard me.

I had a slip up, several actually, every now and again my son (18m) would accidentally catch a glimpse of my ass (with underwear on) or cleavage, all instances making him extremely hard, he had a suprisingly big cock during the time, one night i got too horny and measured it myself when he was asleep 7in, wow.. i thought to myself, i didnt step any further even though i wanted to suck it until he came in my mouth.. i was so horny the next day after work and picking him up from highschool, i threw off my clothes and started masturbating super hard, my pussy turned red really fast, it was late and i heard my sons tv blaring out some video game dialogue mixed with gunshots, but it turned out to be a video from a youtuber, i had no clue, i was masturbating intensely to the thought of his cock penetrating me, he came in hearing me moan and said "MOM! are you-" and thats when he saw me masturbating and moaning, it was not even a second later i squirted all over his face, my bed faced the door to my room so as soon as i was finished it hit his ace like a water pistol, he saw his own mother naked, hot and covered and sweat, i couldn't even stop myself from smiling, i said "sorry baby, sometimes mommy gets too pent up" even after i came i was still fingering myself, i saw his erection in his pants and said "do you want your mommy?" and he stammered it looked like he was about to scream in horror but i could tell something clicked in him and he said "and what if somebody finds out?" i giggled for a moment and said "as if i could give a fuck, give mommy your massive cock" i spread my legs wide to show him my shaved bald pussy and i took my fingers to spread my folds for him he said "fuck.. finally" then he threw off his clothes, his cock was already throbbing visibly, his cock was long and thick with the tip being slightly red like a blush, he rammed himself inside of me, thats when we fucked for hours, to the point that my alarm clock went off, it was 1am when we started, my alarm was set for 8am, he came inside of my tight pussy repeatedly, and i didn't care i loved it, my son making me cum so much and his cock being way bigger than his fathers, i was in love, with my own son, im now (50f) and he is (28m) and we still fuck like rabid animals he got me pregnant recently and we had a little girl.
