A crutch for my pregnant sister

I fucked my heavily pregnant big sister. At the time she was twenty six and I was a shy pimply faced twenty year old more comfortable handling books than girls. I was forever horny and spent a lot of time jerking off after or while reading sex novels and magazines. This was before the time of internet porn. I’d had two girlfriends but had never gotten past the kissing and feeling stage. The last one was a year before this incident. But I had done some fucking, having mustered the courage on about half a dozen occasions over the past two years to invest saved up pocket money on cheap prostitutes.

My big sister Melody had moved back into the family home after her fiancé, with whom she’d been living for two years, had migrated to the USA. Two weeks after her fiancé’s departure she discovered that she was six weeks pregnant. Her pregnant belly grew rapidly, amazing everyone who saw it. By the time she was seven and a half months pregnant she was huge, looking as if she was ready to pop, and moved about slowly, as if she was sick. She often solicited my help to get up off a chair, or to move about the house, especially when climbing the stairs to her room. She called me her crutch.

Prior to her body’s ballooning, Melody had been an agile, thick, five foot eight volleyball player with massive round ass and full, high firm breasts. She was light caramel, a couple of shades lighter than my rich brown, with close cropped curly copper colored hair and spots of freckles on her smooth pretty face. She had full pouting lips and big shiny mid brown eyes. In other words, sexy as fuck!

Due to the discomfort of her huge belly, and accompanying pregnancy complications Melody’s fiancé had urged her to quit her job when she was five months into her pregnancy. He sent money for her support. During the day the two of us were the only ones at home, as I was awaiting entrance into university, and my other sister who was twenty three worked out of town and came home only on weekends. Mom and dad who were both teachers got home around five o’clock every day. Melody and I soon became very much attached, even more than we were before, now that I had to assist her. I even accompanied her to maternity clinic at times.

Melody had never been one for modesty where dressing was concerned, and now that she was pregnant and always complaining of feeling hot and restricted, wore very little around her ample body, especially when mom and dad were not around. During her teen years our dad whose favorite she was, jokingly nicknamed her ‘quarter yard’ which he said was the amount of material needed to make one of the skimpy outfits she favored. I had always been sexually attracted to pregnant women and usually experienced massive hard ons just from looking at or thinking about them. Now with Melody waddling around the house and sitting or reclining on the sofa wide legged I was constantly aroused. Due to the short or loose stuff she wore, not a day went by without me getting flashes of her fat crotch and ass or exposed boobs. Aware that she was my sister I at first tried to fight against the swelling in my pants when I looked at her, but after always failing to control my rampant cock I gave up trying. She had to be aware of my state when around her; for on a number of occasions I’d caught her taking furtive glances at my crotch. But she didn’t seem in any way put off or concerned about the obvious bulge that greeted her eyes. I welcomed the times when she would cling to me to go upstairs, or stretch out a hand for me to help pull her up from a chair or sofa. I relished those soft brushes of her ripe body against mine.

It soon reached the stage where I was mad with lust for my sister’s pregnant body fuelled by the fact that as the days went by she became more and more careless how she sat or lay around while I was about. Sometimes I’d be sitting opposite her chatting and she’d unabashedly open her legs wide giving me a prime view of her fat pussy barley covered by thin underwear. Or she’d be lying on the sofa with one leg bent at the knee causing the short dress or over sized shirt or whatever she was wearing to ride all the way up to her splendid crotch. At times she’d have on a short robe or nightie that should be knotted at the front, but instead was left open all the way as she moved around doing whatever she was up to. It seemed that she felt secure in those states of dress because I was her brother. If only she knew how badly I wanted to fuck her. It got to where I would sneak up to her room and touch or sniff her sheet and pillow or her worn blouses, bras and panties. I love the rich musty smell of her panties crotch, and would even lick or suck on them sometimes.

One day we were sitting drinking fruit juice and chatting idly about music and other light stuff. She happened to be wearing only a loose blue open front silk robe that couldn’t stretch enough to wrap around her swollen tummy while she was in a sitting position and pink sheer panties the waist of which folded up below her belly, barely covering her crotch. She suddenly stretched out her hands for me to pull her up. I got up quickly to oblige her, unmindful of the swollen cock lurching in my soft track trousers. As she straightened up she seemed to lose her footing, and fell forward onto me, almost knocking me over. I quickly threw my arms around her and steadied our bodies. I felt her belly’s softness pressing against my hard erection.
“That was close,” she said. Then suddenly stepping back and looking down at the front of my track trousers, she brought a hand up to her mouth and stared wide eyed at the big bulge.
“Whoa, bro, what you trying to do, give me a C section or something, is that a big knife in your pocket?” She broke into giggles.

I was lost for words, and before I could recover she waddled away in the direction of the kitchen. I looked after her departing body, at the hefty ass bouncing under the thin silk robe and the smooth rounded back of her thickened thighs and legs. I made up my mind right there that I was going to make a move on her very soon. To hell with the consequences, this was too much; I wanted to get lost in my beautiful sister’s sweet plump body and I was ready to take the leap. I wanted to feel those big, round ass cheeks and magnificent boobs in my hands. I wanted to kiss those sweet full lips and suck on her long nipples. I wanted to lick her clit and tongue her hot love tunnel till she shook in orgasm against my face.

The next day, around mid-morning, she came downstairs wearing just a white cotton vest which failed to make it over her distended stomach, or to keep most of her lush boobs from falling out the sides. Below that was a white lace thong that also failed to do its job which was to cover her entire swollen pussy; instead it had slipped into the hot crack, leaving exposed two folds of smooth shaved pussy flesh hanging out for my hungry eyes to devour. I stared open mouthed at the sight approaching as I lay on the low sofa.

“What you watching at?” Melody asked, “Checking to see how much of my tummy you sliced away with your big knife yesterday?” she walked pass me grinning and giving me a good view of her bouncing, huge, slightly dimpled ass, the crack of which completely hid the string of her thong. She bent over a low table to pick up the TV remote and I nearly died at the sight of her fat lump of pussy peeking out at me from between her thick smooth rounded thighs.
“This is it.” I thought as she walked back to the sofa and plumped down next to me, smelling of sweet body lotion. “I must nail that pussy today. She is practically offering it to me, even without my asking.”

About five minutes later she asked me to fix her a snack which I did. For the next hour and a half we sat watching a movie, which for a morning film had a good dose of steamy scenes. She was constantly fidgeting, her bare thighs bracing against mine. Sometimes at a tense moment of the movie she would lean heavily into me, often throwing an arm around me, causing her soft partly freed breast to crush against my arm. I knew she wanted it as much as I did, but neither of us wanted to take the really big first dive into dark taboo waters.
