Hi my name's Ben and I was 11yrs old at the time of this incident in my life my mum June was 31yrs old slim blond hair with legs up to her neck according to my friends, and I had a sister Becky who was 8yrs at the time like a mini mum with hair that came down to her waist. We lived in a small town on the English East coast in the 1980's my dad had died from cancer two years previously. About nine months after Dad's death my sister and I took to running around naked in the summer time just cause it was fun and the sun felt nice on our naked flesh and we got super tans. To our surprise mum didn't seem to mind and she would strip down to her bikini or just bikini pants showing us her lovely little firm tits which had huge aureole on them topped by pencil size nipples. What's not to like? Becky and I had discovered the pleasures of mutual masturbation and since I was now shooting a respectable amount of sperm many an afternoon passed with Becky wanking me to a climax and me shooting my jiz all over her pretty little body. I would then proceed to lick her little cunt and her very prominent clit which stood up like a little penis when aroused. Mum would watch us during these episode's her own hand stuffed down her pants rubbing herself to a gut wrenching climax occasionally throwing off her pants in frustration and spreading her legs giving us the uninterrupted view of her shaved cunt. Sometimes she would ask Becky or I or both of us to help her and we would gladly lick and suck her to climax this usually resulted in me being wanked again by mum or Becky as I would have a painful boner. On my eleventh birthday mum and Becky gave me the best present ever. Mum had given me computer games and clothes for my birthday and I was upstairs naked as always playing with my computer when mum called me to her room. I padded down the hall to mum's room to find Becky naked wrapped in red ribbon with a sign saying happy birthday bruv. Mum stood beside me naked except for her white panties and told me to un-wrap my sister which I did carefully until she was naked on the bed. Becky then spread her legs and folded them until her cute little cunt and bottom was raised in front of her own face her little clit standing red and proud and my own cock throbbing. "Becky wants you to fuck her," Mum told me. "As a birthday present for you, you can have her virginity," Mum reached down and tugged my cocklet and couple of times causing my cock to bounce and sway. "What do you say?" mum asked me stroking my erection in her thumb and forefinger. "Yes please," I gasped squirming. "Thank you Becky," Mum told me to get up on the bed between Becky's spread legs and lick her and make her wet. I did as instructed and paid a lot of attention to Becky's little soldier until with a gasp and a grunt she lifted her hip off the bed nearly breaking my nose as she came loudly. Mum told me to get into position with my cock at the entrance to Becky's cunt and push slowly. It was exquisite and so tight and hot. I went in about 1" then stopped mum putting her hands on my bum to stop me forcing myself. "Are you ready Becky," She asked the panting sweating preteen beneath me. "God yes mum," She panted. "Do it Ben," Mum took a hold of my slender hips and pushed and my cock sliced through my sister's virginity and soon I was 6" balls deep in my sister who gave out an ear shattering squeal then a grunt. "Ok Bex?" mum asked. "Hmm!" she grunted. "Bit sore but feels good," "Good girl," mum soothed her stroking her hair which was all over the pillows behind her. "Start fucking her slowly Ben," mum told me. She came and put her hands on my hips again and helped me get in a slow rhythm before nature took over. I starting fucking Becky slowly and steadily knowing I would not last long. Mum got up on the bed beside Becky and disguarded her pants and was soon diddling herself and telling me to go faster and as I did Becky bucked back up towards me soon I felt my little balls boiling and I knew I was going to spurt. "Mum, Becky, I'm gonna blow," I gasped my hips becoming a blur our flesh slapping together sweat pouring off both of us. "Do it son," mum hissed her own hand a blur in her own cunt. I suddenly felt jet after jet of hot spunk flying into my sister's little body and Becky squealed and shook as she had another orgasm at the same time. After seven spurts I slumped forward onto my sister my little hips still thrusting in spasm. Mum them grunted beside us and came violently like Becky. We lay like this for a few minutes and then I slowly withdrew from Becky my cock tinged with pink from Becky's deflowering but still erect. Mum pulled Becky over onto her and kissed her telling her she was clever. Becky starting kissing mums boobs and slowly slid down until she was eating mum's pussy. Becky's cute little tanned bottom and cunt were pushed up towards me as she licked mum. I gave my cock a wipe on the bed sheet and couple of strokes and then got behind Becky on the bed opening her legs I could see my previous deposit running down her legs. Mum smiled at me and nodded as I entered my surprised sister from the rear my cock sliding into her well lubricated little cunt. She turned her head slightly her face coated with mum's juices and smiled at me as I gripped her hips and started fucking her again. I took a hold of her beautiful hair and used it like reins as I fucked her. Mum shook to another 'cum from Becky's licking's and then pulled Becky to her as I fucked her more forcibly lasting longer this time. I as I felt my balls boiling mum told me to pull out and shoot all over Becky's little bum so I pulled out and wanked myself like crazy and shot 5 ropes of 'cum all over Becky's golden tanned bum I then fell backwards on the bed exhausted my cock still sticking up erect but red. I must have fallen asleep for a few minutes I woke to find mum licking my spunk off Becky's bum and licking her cunt from behind as Becky held onto the headboard. Mum saw me awake and told me to lie still she had one more birthday treat if Becky was willing. She pulled my little erection and felt my balls smiling saying "Still got enough left I think," "Gotta 'cum mum," Becky gasped from the headboard. "And you will my little angel," she said to her stroking her bum. "Come and sit on your brother's stomach," My beautiful little sister crawled over my prone body until she was straddling me her bottom brushing on my twitching cock head causing me to shiver. "Becky's going to be a cowgirl," mum told me slowing cupping my balls in her hand. "And you're going to be her horse," "Wow!" Becky sighed. "Brilliant," I said loving the feeling as mum massaged my balls. "Becky how would you like to try something different?" mum asked my naked sister. Becky was slowly massaging my cock with her little cunt lips and clit as mum spoke. "Yes anything," she panted "This is sooo much fun," "Ok," said mum and she reached for some cream on the bedside cabinet she then took some cream which was cold and rubbed some on my throbbing cock the rest she put on the entrance to Becky's poop chute and Becky gasped at the cold liquid. Becky them squirmed as mum's finger must have pushed into Becky's bum. "Oh that's nice mum," Becky gasped, "Different but nice," "Good dear," mum said as she carried on finger-fucking Becky's bum. "Now Becky lift your bum up and I will position your brother's cock at the entrance to your bottom then slowly slide down onto it. It will be tight but we should make it," Mum and Becky moved into position and I felt mum's hand rubbing my turgid cock and it come into contact with Becky's bottom the slowly and exquisitely there was a tightness then my cock slipped passed he anal ring and I slowly slipped into my sister's bottom. Becky growled with lust and told her to slowly move up and down until she felt more comfortable and mum showed me how to diddle Becky's throbbing clit with my fingers as she started bouncing on my lap. Becky's bum felt so tight but soon she was bouncing like a rodeo and I couldn't keep diddling her so I held onto her hips as she bounced and groaned. Mum climaxed again beside us. Becky was bouncing wildly my cock started to boil "Cum Ben Cum!!" Becky hissed at me her hair flying everywhere. That did it my balls boiled over and I had the most intense orgasm ever and I emptied myself deep into Becky's bottom. She squealed and came again forcing her bottom deep onto my quivering cock ne last time. She collapsed onto me panting and very slowly I felt my cock slipping from her bottom. We all lay exhausted Becky on me and mum beside me. What a birthday I thought to myself. We all drifted off to sleep and didn't waken up until the next morning in a sticky pile of soiled bed sheets. Mum was already up in the kitchen I could hear. Becky had slipped off me in the night and lay sleeping like an angel albeit a well fucked angel. My cock was raging but I didn't want to waken Becky so I padded down the hall to the kitchen still naked. "Hi mum," I said. Mum was naked and busy making breakfast. "Hi stud," she glanced around. "God the that cock of your is still not satisfied," she said looking at my morning erection bobbing in front of me. "I know mum," I bleated. "And it hurts and Becky's still asleep, and I've got football (Soccer) this morning," "Come and sit up on the worktop and let your mum fix it," mum said playing along with my "poor me" routine. I sat on the workshop my legs dangling my cock nearly touching my belly button my balls aching. Mum eased me forward until my balls hung over the worktop edge and she spread my legs and she leant forward and started sucking my cock. Due to my size she could swallow all my cock and lick my balls at the same time which was some turn on. Soon I was humping her face and she back off a little and I slowed down. Soon my balls boiled and I grunted to her that I was gonna cum but she kept on sucking and I filled her mouth with five jets of my boy cum, and she swallowed it all. My cock remained hard as she released it from her mouth but very satisfied. "Thanks mum," I gasped. "That was awesome," "Sit there a minute," she said and got up and went out of the room for a minute returning with pair of white pants and my football shorts. She slides the pants up my legs and shorts and told me to lift my bottom which I did she then pushed my little erection into my pants and shorts. "That'll keep that out of harm's way," She laughed. "For the rest of the morning," I jumped down my shorts tenting slightly. I pulled on my football shirt, and mum produced cereal and I sat and ate my breakfast as normal as anything. As I was finishing my breakfast a naked Becky walks into the kitchen her little body still glistening with trails of dried cum from last night and her pussy lips were puffy red. "Shower young lady," Mum tells her. Becky turns and heads off scratching her cute bum as she goes. "Don't get any ideas," Mum tells me as she sees me eying Becky's bottom. "Time for that later or you'll be late for football," "Ok" I say. "Becky hurry up," Mum calls after about ten minutes. "I got to take Ben to the football and you've got to come," "Mum," Becky appears wearing a my little pony t-shirt and nothing else naked from the waist down stroking her hair with a brush in one hand and rubbing her cunt with the other her little clit standing proud like a little soldier on guard at the gates to heaven. "Becky put some pants on and leave your pussy alone," mum tells her. "But mum it's sore," Becky tells her. "It's bound to be sore your brother fucked both your pussy and your bum last night and you came goodness knows how many times," mum sighed at her. "Just put these on don't worry about panties," Mum hands her a short skirt with a blue and white pattern. Mum slips into a set of joggers and we head out to the car. Mum makes me sit in the front as she doesn't want us touching each other up on the way. Becky sits legs spread rubbing her pussy nearly the whole journey despite mum telling her not to, and I struggle to keep my erection in my pants. At the football pitch I see my mates and my erection wilts to save my embarrassment and I'm glad for the moment. Becky shuts her legs and I kiss mum good bye. "See you later," mum says. "Pick you up at 12:00," "Ok!" I say and run off. I hear mum start the car and drive off in the background. On Tuesday and Saturday's I played football for our local under 12 school team and mum drove me to the games and collected me after while Becky was at ballet classes.
