Fulfilling an old fantasy..

This story is completely fictional! NEVER try to do it in real live!

My mother called last night and asked me to stay for a week with her and my 12 year old sister Heidi. She said that my father was going away to Japan for a week-long business trip and she and Heidi were afraid to stay alone because there has been some burglaries in their exclusive neighborhood lately. I was only too glad to oblige.

I spent half the night thinking about mother. She gave birth to me when she was 16, two years before she and father married. It was 18 years later that Heidi was born. Although Mom is 40 years old now, she still kept her blonde magnificent 38D-26-38 figure. I remembered how it all started right after Heidi was born. I had begun to show great interest in women's bodies and my by then 10" long cock was in a constant state of arousal. She always breast-fed Heidi in front of me causing a big hard-on and one day while sitting next to her nursing Heidi I hit upon a great idea! I pretended to play with Heidi and I brought my mouth next to mom's breast, pulled it away from Heidi and started to suck on it. Heidi fought back to reclaim her rights and pushed me away. Mother laughed, offered me her other breast and said: "You don't have to fight. Here, I've another one for you." I accepted gladly and started to suck and bite her nipple.

Greedy Heidi tried with her little hand to push me off the other tit which gave me a chance to knead the big mammaries and to rub my cock along my mom's bare thigh. Soon Heidi went to sleep and I was left with both succulent globes. Mom caressed my hair as I mauled her tits with both hands while I sucked and chewed on her nipples. I was by then held tightly between mom's full thighs while my hard shaft, its helmet now above the rim of my shorts, rubbed hard along her lightly covered pussylips. I could not contain my youthful excitement and soon my hot cum oozed between us. She hugged me tightly to her as felt the hot sticky stuff penetrate her thin dress and touch her skin. I was totally exhausted and I slept like a baby on top of her.

From then on she was more aware of my constant hard-ons and she helped me discretely relieve them. In contrast to her normal conservative dressing style, she began to dress scantily when we were alone around the house showing her ample breasts and long sexy legs. Summer mornings were the best. I would set at the kitchen table and watch her prepare breakfast dressed in a short transparent night gown and panties.

I could clearly see the dark nipples on her huge tits and the blonde batch of hair covering her mound. My hard cock would appear down the leg of my shorts and I would start rubbing the head gently in anticipation of more delights to come. After breakfast is finished, I'd pretend to help her with the dishes while taking every opportunity to get behind her and hug her to me and rub my cock between her soft ass-cheeks.

She'd then turn around planting a motherly kiss on the corner of my mouth while I rotated my hips to increase the friction between my cock and her ass and cupped her tits through the thin silky nightgown. Sometimes my hard cock would escape down the leg of my shorts, left her gown and wedge itself between Mom's warm thighs. She would then clamp her massive thighs shut around my cock while I slowly fucked between them, freed her tits from the gown and mauled them gently.

Later she would go in her room to take a shower and change, leaving the doors open. I would sneak in the bathroom after her, pick up her wet panties from the floor and start to jerk off while sniffing the musky aroma of her pussy and watching her through the semi-transparent shower door. I would hear her moan loudly while one hand moved between her legs and the other caressed her breasts. Sometimes we would reach a mutual orgasm, she trembling under the warm shower while I emptied my load in the crotch of her silk panties. Then she'd acknowledge my presence and ask me to pass her a towel.

I liked to help her dry off her tits and bum while she dried her hair with another towel. She'd bend over the sink to give me a excellent view to her great ass and enabling me to access dry her pussy from behind. That is how I came in contact with her enormous clit for the first time! It was over an inch in length and as thick as a thumb and I noticed that she trembled, bent her knees and goose bumps covered her skin whenever I came in contact with it. I learned to hold it between my thumb and forefinger, through the towel, and twist it gently while she trembled, panted and groaned and her pussy and asshole opened and closed rapidly, her juices running down her thighs. She'd lose herself for a few minutes, breathing strangely, before she regains control and take my hand and pull me to her, hugging and kissing me feverishly while I cupped her soft buttocks.

But the best happens after lunch, when we go for a dip in the pool. I would start a water fight with her and we'd end up wrestling in the shallow end of the pool. The slippery water presented an opportunity to grope her huge tits and to cup my hand over her hot cunt, coming in contact with her large clit. Sometimes a couple of my fingers would slip inside her bikini and caress her pussy lips and tweak her erect clit. She would hold my balls tight in her hands and run her fingers along my hard cock until she reaches the exposed head. Then she would close her fist around it and say to me in her husky voice: "Mmmm... my. How you've grown. You're already bigger than your father. I'm so proud."

We'd usually end up at one corner with her pinned under me, my hands kneading the huge tits hanging out of her bra, her legs wrapped around my hips and my cock-head pushing her bikini inside her pussy before it meets and duels with her protruding clit. Then she'd pull my face to hers with one hand and kiss my mouth gently while her other hand would run all over my back and buttocks until her body convulses in orgasm.

Later she would ask me to rub suntan lotion on her back by the pool side. I always took the opportunity to roam my hands between her thighs, over her buttocks and along her sides reaching for her huge tits. On these occasions she would lie on her stomach in her string bikini, remove her bikini top and spread her legs wide so I can sit between them to administer the lotion. I would apply copious amounts of lotion to her ass and manipulate the thin material of her bikini until it is wedged between her pussy's shiny lips and until her rosy asshole is partially visible.

Then I'd pull my cock out, grease it with suntan lotion and lean forward to apply the lotion to her shoulders, placing my by then hard prick between her hot salient almost bare buttocks. I would slide it along the crack of her ass while kneading her shoulders. she would moan softly and push back ever so slightly. I would contrive to bring my cock in contact with her asshole and rub it against her slippery anus. I reached my climax in this fashion quite a few times and rubbed my cum over her ass cheeks before jumping quickly into the pool to wash the evidence.

Sometimes, during my father's frequent business trips, she would ask me to share her bed at night. She'd wear her skimpiest and sexiest silk lingerie with half-cup bras and G-string panties. We would French kiss and frolic for a while with me massaging and sucking her enormous tits while my rampant cock slid between her massive thighs and along her pussy. Her flimsy silk panties were no match for my lance and it would push the material inside her cunt until the head is completely inside. We'd fall asleep with her back to and my hard dick under her panties, her pussy-lips entwined around it.

Early in the morning I'd wake up before she does with the usual morning hard-on lodged between her wet, hairy cunt lips and I've pushed it inside her wet hole on occasion, fucking her gently as she pretended to be asleep until my balls cramp with cum. I usually pull out and bury the tip between her buttocks, about a half-inch inside her puckered asshole, and release my hot cum only to feel it gushing out over the tip of my cock. Some days it would be my turn to pretend to be asleep while my mother slid under the sheets and swallowed my dick until I come deep in her mouth.

When I was 16 she began to take dancing lessons and often asked me to practice her steps with her. By then I was four inches taller than her 5' 10" frame and it was more difficult to hide my adolescent hard-ons. Those practice sessions would invariably end with a slow dance, she holding me tight, her tits crushed against my chest while my hands glided over her ass. I grow bolder with time and started to knead her buttocks and pull them apart through her dress.

One particular evening we were alone in the living room, Heidi asleep and my Dad working late plotting his latest takeover strategy. She put on a CD and asked me to dance with her. She was wearing a thin summer dress that came halfway down her thighs and covered very little of her large tits. Her nipples protruded invitingly and I'd noticed earlier the she was wearing her sexiest French hip-hugging panties I was wearing a T-shirt and light cotton pants with an elastic waist-band, without underwear.
