My mother had me at 14, had to give custody of me to my fathers parents, where i lived with them until i was 12. I moved in with my mother and her husband at 12 but i didnt meet her for the first time until i was 10. Regardless not long after i moved in i ended up seeing her butt naked and sprinting through the house to answer the phone, she was showering and we were suspecting a phone call from the hospital any day about her husbands mothers health. Which was how i saw her nude because i knew she was showering and went to answer the phone myself. However when i saw her running, soaking wet and titties bouncing, i froze and my mouth fell open. She paused when she saw me but laughed at my expression before she answered the phone and wrote something down, leaning over the counter in a way that i saw her sex from behind and instantly got hard. She came to my room in a bathrobe to check on me after getting off the phone, where i sat on my bed hugging my knees and rocking in shock. She laughed and said i looked like i had seen a ghost and made a comment about how my father used to get pale like that whenever he saw a lot of blood. I had joked about having bloodloss too but since i was hiding it she didnt know what i was talking about and thought i had hurt myself so she was insisting i show her where “i was hurt.” and since she wouldnt let it go i just flat out lowered my legs and showed her my bulge where she immediately didnt understand still. She had even asked what it was and thought i had something in my pocket, up until i started flexing it and making it bounce. I remember her expression when it all clicked and how she had told me “dont make a mess of your sheets!” playfully as she had left the room. Before that though she had told me it was flattering and had even made a comment about my size. Regardless it was probably nearly two years later before it happened. I had gone to a beach one summer with some friends and ended up so badly sunburnt that i had gotten sun poisoning and was deathly sick. My mom took off work for a few days to take care of me but i was so miserable and refusing the hospital that she started giving me shots of liquor instead. By the time night rolled around she kept coming back and checking on me, rubbing on more aloe and changing my bandages since i had massive blisters and what not but around 2am she realized i was still awake and miserable and felt so bad that she was nearly in tears as she had asked me if there was anything she could do to help. I had told her the truth and that the only time i got any relief was when she was actively rubbing me with the aloe, so she ended up inviting me to her and her husbands bed where she kept rubbing my chest and back with lotion until i fell asleep. however she woke me up when she rolled over later since she was kind of snuggling me. Her husband then was an alcoholic too and had gotten wasted on liquor before bed for the fact i had hit him in the face earlier that afternoon. He had smacked my back and asked me if it hurt so i had hit him out of reflex, and when my mom got pissed and jumped his shit he just started drinking until he passed out. He was in bed too but snoring like a chainsaw. Now my mom has always worn the same silk night gown to bed for as long as i had lived there. So thin one could easily see her nipples imprint through it and the fact she didnt have panty lines, though she usually wore a bathrobe over her gown until getting into bed, but, that night after she woke me up i had touched her hip and rocked her a bit to see if she was awake but she had while sleeping reached up and grabbed my arm, pulling it around to her chest where she had placed my hand right between her breasts. Since it was a v cut too my hand had slid down under her gown and i ended up feeling her nipple, not even on purpose, just from where she had pulled my arm around herself. Needless to say i got hard and since i was in boxers i could feel her ass on it easily, and somehow it had gotten erect out of the slit of my boxers so that my cock was fully exposed and it ended up between her thighs. I seriously didnt do it on purpose but because of the way she was laying i ended up perfectly between her thighs so high up that i literally could feel her vagina touching the top of my shaft. I had tried to pull it out of her legs but she had actually groaned and backed up onto it even more and well, i ended up slowly thrusting into her thighs and realized quickly that she was slightly moving along with it, like bucking and grinding a bit as i had moved. I ended up convincing myself she was awake, as, by then i was groping her tit directly and basically fucking her thighs, and once i thought she was awake i had just went for it. She had gasped awake saying, “No! we cant, my son is..” but partway into saying this she saw it was me and froze. She thought i was her husband at first but she had gasped and her mouth fell open, a hand immediately covering her mouth, but she had promptly not said a word and just lay back down. I sat up as i kept thrusting in and out of her for a minute just long enough to make sure she wasnt going to try and wake her husband and when i realized she wasnt going to i went all in. I played with her breasts and kept whispering into her ear as i took her, telling her how good it felt and how i loved her and felt better because of it. I finished inside of her and didnt even pull out, left my cock still in her as i went to sleep.
