I was born and bred in West London, literally under the flight path to Heathrow. The planes were so low that I could see the pilots in the cockpit!. I didn’t even notice the noise and congestion until I went to University in a less busy city on the South coast. Having discovered a quieter less-frantic pace of life, I was not keen to return. My mother in particular was upset that I found a job about 40 miles or more away from home, about a quarter of the way around the M25 clockwise and north a bit.

After a few years of lodging with a landlady during the week and travelling home at the weekend, I managed to scrape enough together for a deposit on a nice upper floor one bedroom maisonette in a small town a few miles from where I worked. Soon after my younger sister, Diana, asked if she could come over for a long weekend along with her best friend, Carol. However I should have been suspicious when she asked if she could also bring Carol’s older sister, Sheena. I suspected that she had fancied me for years but the feeling was not mutual.

So early one Friday evening, my sister and the sisters rolled up in her small Fiat 500. Both were short and dumpy with Sheena being the taller yet still not even reaching 5 foot. Rounded chubby cheeked faces and short squat necks were complemented by short brown hair. Sheena’s was lighter in colour, styled in a soft bob with a fringe across the forehead and hanging over the ears. Each had a large pleasant cheery face with a full lipped mouth, a small sleek nose and small eyes, yet I was attracted to neither. To top it all, Sheena wore large rimmed glasses and reminded me of Velma, the short dumpy geek girl from Scooby-Doo!

Hi Jim, thanks for letting us stay Sheena said in a soft voice and a smile as I welcomed them. To my discomfort I found myself looking down at a short rather plump girl as she squashed me up against her rather large chest in a tight over-familiar hug. On her short frumpy body, her assets were fricking huge. Wide and full, they thrust forward like sexy bumpers covered in a white long-sleeved top. However to me she was just another short fat girl with big boobs. OK that was a bit harsh as she was pleasant, intelligent and cheery but she just wasn’t my type. Having said that, I did notice the way her jeans clung tightly to her short thick legs. Maybe it was just how plump they were but they stretched the denim into exciting curves around her thick thighs, swelling out at the back around her hamstrings and over wide chunky calves.

As they settled in I got the impression that my sister was trying to set me up with Sheena. It was small things like making us sit together on the sofa and pointing out things we apparently had in common. I didn’t want to be rude to my sister in front of her friends so just joined in without trying to show too much interest. In case you were wondering about the night-time arrangements, the girls brought sleeping bags so they could camp out on the floor of the living room while I took my second-hand single bed in the rather small bedroom at the back.

The following morning after we’d gone to the market to get in some provisions, Diana and Carol decided to drive to a historical aircraft and vehicle museum at a local airfield. However Sheena was going to stay ‘to keep me company’ fuelling my suspicion that I was being stitched up. You might as go with them I told her I’m just going to do some painting (I do oils) while listening to some music. You’ll find it boring but she just gave me a big smile. Shortly after the others had left she took off to the bathroom to freshen up. I had hoped that she had gotten bored watching me with adoring eyes as I painted. However when she reappeared, I didn’t know where to look. Wearing a low cut white top beneath an open checked shirt, it was so tight that her big nipples were clearly visible pushing up the material like studs. It was also low cut so I couldn’t stop my gaze from plunging down the deep dark cleavage between massive orbs of wobbling feminity. As she walked across the room, they bounced and swayed in a manner that went straight to my loins. Her jeans were replaced by a pleated skirt that came down just above the knee with her short chunky legs pushing it out in long deep curves hinting at large hamstrings and short thick thighs. Tan-coloured sheer nylons covered a very large pair of calves. Her ankles slim but the back of each leg flaring dramatically to a big wide curved edge mass. They certainly looked very sturdy but I dismissed it as just another aspect of being overweight.

I was sitting on the edge of my sofa with my easel before me holding my latest piece in progress. A box of paints and brush holder were on the floor close to hand. David Gilmour’s About Face was on the CD player. OK, not that heavy I know but a lot heavier than the pop music my sister listened to. Sheena walked over to the wide triple window that provided the front view from my top floor pad. I noticed that she was wearing a touch of make-up and along with her sleek little nose actually looked good with it. Standing side-on to where I sat, she gave me full blast of her side profile with her huge breasts thrusting out dramatically from the rest of her body. Seemingly lost in the music she began swaying with the rhythm. Orrrghhh what a pair! I groan mentally to myself unable to stop following the curves of that low-hanging frontage as it wobbled gently from side to side in a manner that was highly erotic and impossible to look away from.

The swaying became more pronounced. It was practically a slow on-the-spot erotic dance with huge heaving mounds of womanhood that set my heart racing. My first interest in girls were those with big breasts and Sheena’s were larger than most. The sight of so much heaving female bosom was a black hole for my eyes. Hooked, I couldn’t stop staring, which I suppose was the whole idea. The way she moved that endowment was breath-taking and I was getting aroused. I felt awkward as I didn’t fancy her as a person and uncomfortable she was coming onto me like this. Forcing myself to look away and go back to my painting I resisted her blatant advances.

Not that she gave up. So deep, so meaningful she purred as Cruise came on still slowly dancing around while looking at my stuff on the units that took up most of the opposite wall. I tried to ignore her until suddenly an exclamation of interest made me look up. Put that down! I shouted in horror. Sheena was looking through an issue from my stash of American female bodybuilding magazines. This was a few years ago when it was not socially accepted in this country for women to flaunt muscular bodies and considered abnormal behaviour for a guy to get turned on by it.

I was mortified, knowing that she would tell my sister who would tell my parents and that would be the end of the civilised world as we knew it. To prolong my embarrassment she was looking at the pictures, while still swaying that wide low-slung chest seductively, with what appeared to be interest rather than open disgust. Interesting she remarked. Please Sheena. Leave that alone I was now begging. She flashed me a glance through her spectacles. Of course, Jim she said in a gentle sympathetic voice instead of shouting at me calling me a filthy pervert. Closing the magazine she returned it to the pile inside one of the units with much show of leaning forwards unnecessarily in my direction giving me a clear view right down the neck of her top and the titanic mounds clashing together beneath.

How do you talk with a girl who has just discovered your deepest darkest secret? Hundreds of different scenarios and conversations played out in my mind but none prepared me for what Sheena said next. It’s alright she said in a soothing voice I understand she smiled. You know that I’m a healthcare assistant she told me. I vaguely remembered Diana mentioning it. Well that means moving heavy beds and lifting patients she added as if that was relevant. In the next instant the over-shirt had come off and I couldn’t believe my eyes. It looked like she had tan coloured bowling balls in the middle of her upper arms. Was she deformed in some way? What were those strange rounded lumps? One answer was screaming at me at the back of my brain but I just couldn’t accept it. Pretty big, eh? she says in understatement with a smile then bent her right arm by her side. It was only slightly bent but, Oh My God! I swallowed deeply as disbelief turned to shock as that rounded mound became fricking massive and very solid-looking. As if to emphasise their true nature she pressed her right fist into her left palm. I gasped loudly as that huge shape twitched and bounced in an unreal manner that had my dick stiffening fast, now in no doubt that I was confronted by biceps of a truly tremendous size. Orrrrrrr wow! I groan in incredulity. Doing this job since leaving school has made me quite strong she smiled enjoying the shock on my face and reaction in my trousers as that melon-sized mass pumps and flexes in a sinuous slinky muscular motion beneath her smooth skin. I just can’t take my eyes of it.

My heart raced in anticipation as Sheena raised her arm in line with her shoulders. I knew what she was going to do yet still found myself holding my breath unable to believe that this was really happening. Slowly bending her forearm towards her head with the fist clenched, her upper arm thickened with a big solid mass sliding beneath the skin, swelling outwards as the hard-looking mass grew upwards in a beautifully curved solid peak. Opposite this, a long curve deepened sweeping along the underside of her short arm. The combination of Sheena’s wide-based forearm and deep triceps while a tall rounded peak of muscle soared upwards had me groaning in pure lust. As her biceps hardened into hefty steep-sided peaks of pure power my dick went rock hard as if set in quick-drying cement. I was completely blown away by the sheer size of that tan-coloured boulder on her upper arm and turned on by the implied power. Yet I still was unable to get my head around this being the short dumpy girl I’d ignored for so long.

Oh God they’re massive! So beautiful! I exclaimed along with similar dumb comments because my brain was stuck in neutral. For a young woman who wasn’t into any kind of sport, they were immense, occupying the full length of her upper arm with a mountain of muscle that soared to an amazing height. I was up on my feet before her trembling with excitement before I realised it with my dick so hard that it strained awkwardly against the inside of my jeans. I had often dreamt about what I would do with a muscle girl if I’d managed to get one alone but now that there was one standing before me I genuinely didn’t know what to do. A wide knowing smile spread on Sheena’s face Go on, feel them. You know you want to. She grabbed my hand and placed it firmly on top of her biceps. My hand visibly shook like a nervous schoolboy touching a girl for the first time as it felt that unbelievably huge mound. Jeez! I gasped in disbelief, stunned to discover that her biceps were so large that I couldn’t even cup them with both hands. Somehow I still expected the arms of the chunky girl to be soft but they were remarkably dense like iron and incredibly full. No matter how hard I squeezed I couldn’t make an impression. You must work out I gasped in awe. That’s years of lifting heavy cast-iron NHS beds and obese patients she chuckled as my dick hit new levels of rigidity. I’ve never seen the inside of a gym in my life she added. Feeling her mighty biceps, I felt intimidated because they were several orders of magnitude larger than mine. You’re interested now aren’t you? she chuckled.

With her forearm raised I saw how exaggerated it’s shape was. Very wide and rocky at the base, it tapered in towards a slim but sturdy looking wrist. I grabbed hold of her wrist with both hands and pushed against her raised arm to no avail. Her arms were as solid as iron pillars and wouldn’t budge no matter how hard I pushed. Strong aren’t they? she asked needlessly with a smirk at my useless efforts. Sheena was no athlete but a natural plump plain girl next door type yet plainly very much stronger than I was. Rather than feeling humiliated, I was truly turned on to an extent that I’d never felt before.

If you like that then this will blow your socks away Sheena laughed. The smile pushed up her chubby cheeks in amusement as her small brown eyes fixed me through her glasses beneath her wide floppy fringe. That’s when she raised the other chunky arm and let me have it with both barrels. Orrrrr! a loud sigh of yearning left my lips and my dick lurched in my pants. I didn’t stand a chance! How was a man expected to handle that? Not only was I right up close to a truly massive pair of dense bulging muscles like a pair of flesh coloured melons but her wide low-slung breasts now rose up like twin beach balls inside her tight top to form a massive double mound with a deep valley between. They stood proudly swollen peeking over the neck of her top as firm as if she were wearing a push-up bra several sizes too small. As if they were trying to break free, the edges of her brown areola peeked over the sides of the v-neck in a highly erotic manner that set my cock thumping so hard I feared it would wear a hole in the front of my trousers. God! I’d never seen anything so sexy.

Don’t just stand there with your mouth open she laughed. Feel them. Go on. Faced with massive swollen breasts and huge bulging biceps, she didn’t have to ask twice. Running my hands over both raised arms, I gasped in awe at their immense size, hardness and warm latent power beneath my hands. Now feel my tits she laughed. My hands darted right for that thrusting shelf of feminity and was amazed by how firm they were. Pretty big too, aren’t they? she sniggered as I began moaning like an idiot as my hands cupped and caressed her mammoth firm breasts with rising lust. What do you prefer my big tits or my big biceps?. I lost it completely. Taking hold of her waist, although unable to pull her close, I began kissing her lips passionately. My hands dart between feeling her massive hard biceps and huge firm breasts while my dick lurched frantically in my trousers in pure unadulterated lust. Oh God! It’s like worshipping a Goddess as she stood with a bemused expression flexing both arms with her bust swelling like two balloons. Oh Sheena! Oh Sheena! I moan like a lust-drunk imbecile begging for her while unable to get enough of her big muscles or big boobs.

She laughed at my intense lust-crazed attention as I slobbered all over her like a horny dog. Then those mighty arms lowered and to my astonishment wrapped themselves around my middle. All of a sudden I’m very much aware of how developed her shoulders and traps are and how large her upper arms were as they embraced me. I’m truly shocked by the feeling of fearsome strength emanating from her thick arms. Feeling enclosed and claustrophobic trapped in a wide sea of huge female muscle, I realise I’m completely out of my depth. Orrraghh! I moan in discomfort as those big arms pull me against her body. Oaargghh! I’d never realised how hard a girl’s body could be, even one as buxom as this. Oh, I know how to handle the occasional unruly patient Sheena chuckled as she bodily lifted me right off the floor crushing me so hard in a bear-hug I could hardly breathe. I was stunned that a girl I thought of as plain and boring was lifting me into the air and squashing my middle like a tube of toothpaste. Sheena’s biceps bulged with raw power as I struggled helplessly in arms so thick and swollen with hard muscle that I was genuinely afraid that she would break me. Beads of perspiration soaked my forehead as I repeatedly tried to wriggle and prise myself free but it was useless. It was as if the ground had opened up and swallowed my body up to the chest in concrete. Ooh-hh! Too much! Her arms were just too much, her superior strength totally overwhelmed me and that really shocked me. Even though she was much shorter than me, I felt tiny and weak in her massive bulging arms. Everywhere I put my hands was huge rock-hard muscle. Straining against that vast dense rippling landscape entrapping my body was intimidating yet exhilarating at the same time and, yes, I was still very much erect and growing stiffer all the while.
