Everyone involved in this but me is dead and gone now, so I can tell this, but I will still change the names just in case someone puts 2 and 2 together. I will start with some background.
I was born with a club foot. I was otherwise normal except for having a large penis for my age. I remember my mother bathing me with my aunt looking on and both of them remarking on what a nice penis I had, and they both fondled it a lot, which felt very nice, but no more at the time than a backrub would be. My clubfoot would be repaired with surgery when I was 20, but no one knew that back then.
My Dad was a hardworking man who played a trumpet in a nightclub for extra money to make ends meet, so a lot of the time when he came home, he was exhausted, so he would eat his supper and go out like a light, then get up and go to work again. Mom later told me that when he did have sex, he would hop on, last 2 minutes, then go to sleep. Dad never allowed Mom to come to the nightclub with him, he claimed it was too rough for her, but the truth was, his first wife had done that, and wound up fucking half the town before he found out and divorced her. And besides, Mom was way prettier.
One night a week or so after I turned 16, I had gone to bed with my usual action comic books, and in the next bedroom, Mom had a glass of wine, about her third, and an erotic novel. We were both reading when suddenly she called out to me. George! Come in here, I need to talk to you! I got up and limped in. She was sitting propped up with pillows, in a see-through teddy, with the covers up over her waist. I could see her nipples sticking out like thumbs. She said “Your father should be doing this, but he’s always working, and besides, he wouldn’t say shit if he had a mouthful, so it’s up to me. I have noticed a mess in your bed every morning, so you need to know about sex from someone who knows so you won’t wind up knocking up some poor girl. Do you know how babies are made, dear?” I said, “Oh, yes, my friends have told me all about it.” She said, “Well, I want to make sure you have your facts straight. A man puts his penis in a woman’s vagina, he slides it back and forth, then that stuff called sperm comes out and goes way up inside and starts a baby sometimes, though not always.” I said “I thought that stuff was called jiz, and a girl’s thing was called a cunt. The guys call my thing a cock, but I remember you and Aunt Grace calling it a penis.” “Those are the fun names for those things, the ones I use are the medical names, but if you would rather use the fun names, it’s all right with me” I said “I have heard descriptions, but I’ve never seen a girl’s va-gin-a. Could I see yours?” She didn’t say anything for a minute, then she said, “I guess it would be OK.” She then slid the covers down, pulled her teddy up, and spread her legs. It had hair around it, with puffy lips slightly parted, with a prominent bulge at the top, and what looked like a gob of spit running out. I said “The guys call that bump on top the Man In The Boat.” She said, “That’s my clitoris.” I said “Can I touch it?” She paused again, then just said “OK” I touched it, and it jumped a bit, so I thought I might have startled it, so I started to gently rub it. Mom gave a little groan, but didn’t say anything so I kept rubbing it, and the spit really started running out, and I started smelling this great aroma. Without asking, I lowered my face and stuck my tongue in it, tasting that stuff, which tasted great, so I started licking. Mom hollered right out! OMYGOD! WHERE DID YOU LEARN THAT? I stopped, and jumped back. “I’m sorry, Mom! I didn’t mean to hurt you! It just smelled so good! I’m sorry!” I jumped off the bed and started to leave. “NO! don’t leave! I didn’t mean it that way, it felt really good! Most men don’t know a thing about doing that, and if they do, they don’t do it right. Your father won’t even talk about it! Come back here, we aren’t finished yet, George, not by a Damn sight!” I came back, and knelt down again, only this time, Mom was rubbing her clitoris with two fingers. I started licking and lapping again, and she purred, “Do you really like that, Georgie?” I nodded my head and kept lapping. After a couple minutes, Mom threw her head back and hollered again, “Oh YES! YES! YESYESYES! Her hands came up to the back of my head and pushed my face hard into her cunt, for a minute I couldn’t breathe, I wiggled my knees around, and my cock flipped out the front of my pajamas. Mom’s eyes widened, she grabbed it and squeezed, then started stroking it. She said, “OHMYGOD, I’MGOINGTOHELL BUTIDON’TCARE! She brought both legs around mine, and pulled me towards herself, and without letting go of my cock, guided it into her cunt. When her cunt touched my cock, I erupted so hard I thought my head was going to cave in. We stopped, with about a cupful of sperm running out of her cunt. She grabbed a handful of tissues from the side table and cleaned us up. Then she said, “I never meant for this to happen, but now it has, so we might just as well get the benefits from it. You obviously need regular fucking, and so do I, so we are going to get busy making up for lost time! You can never tell a soul about this, though!” I nodded. She opened her legs and started rubbing her cunt looking at my cock, and up it came again. “Now that’s my boy!” “Lets have a real fuck now!” About ten minutes later, we both came again. Mom finally sent me back to my bedroom, it was almost time for Dad to come home. When he did, I heard them fucking for about three minutes. after that, we fucked regular until I was twenty two and joined the navy. Dad died of a heart attack, and Mom remarried a man who kept her fucked, but once a year, we met and fucked for old times sake.
