This was an older story that I rewrote to create a version that caters a little bit more to the apparent likes of this sub. The original, which involves two males, is also posted here.

Double or Nothing (Version II), by whosbiggernow

"Play a game?" She asked with a nod towards the pool table. I had been minding my own business at the bar, throwing back beers and whiskeys when I first saw her come in. I had flashed her a sly smile before playing it cool and returning to my drink. It hooked them every time. In a matter of minutes the busty red head had sauntered over.

​

"Sure, yeah I guess..." I said, still playing it cool. As I got up from the stool I realized I was a little deeper into my drinks than I had realized at first. It was probably just enough of a handicap to make the game fun. My college years in the frat house hadn't gone too much to waste - I still could dominate the table. Lusty thoughts of dominating her swept through my alcohol-addled mind.

​

I saw her watching me out of the corner of my eye, so I grabbed my drink and threw it back to finish it off; making sure to flex in the process. My biceps knotted up tight under my fitted polo.

​

"Ladies first," I motioned for her to break. She shook her head.

​

"Suit yourself," I said coyly and lined up the shot. The balls scattered with a loud crack, the red and blue solids dropping into the far corner pocket. We went back and forth through our turns, a round or two, and after she couldn't even sink a stripe I began to think that this was a hustle. Still I played on and in short work I was angling behind the Eight Ball.

​

A beautiful woman like her; I knew she probably didn't come her to play. I'd been through this routine more times than I could count. They "oo" and "ah" as you work circles around them and then throw themselves at you for your skill and prowess. It wasn't much work for an lay, and I was needing one. I took in the sight of her, standing at the far end fo the table hovering just over the top of the ball. She was a gorgeous thing. Almost too good to be true. Usually the ones that pulled this kind of stuff were sixes or sevens, but she was a solid 10. She wore a flattering blue dress that showed off her neck and collarbones nicely. She had a decent build, athletic; not too gaunt or too heavy.

And a rack that was, well, better than the one that had been on the table most certainly. Absentmindedly my tongue licked over my lips as I had a momentary dream of ripping her dress off and railing her against the wall. The whiskey must have been working its black magic, because despite the lustful thoughts my member barely twitched. I shook my head to clear my thoughts and lined up the shot. I was going to need to stall, give my body some time to right itself. "Eight Ball, right corner pocket" a called out before tapping the ball. I had intended to miss the shot but it seemed like I was too good for my own well being - It rolled a bit and dropped in.

​

She looked crestfallen, and I crossed the table and rapped an arm around her. I made sure to pull her in tight so she could feel the hard, corded muscles beneath my shirt. She didn't resist.

"Don't feel bad," I offered gently. She leaned her head back and looked up at me a little bit. She came up right under my chin, which meant she must have been about five-six or so. "Undefeated champ since '09 right here," I barely whispered as I felt her hand come up under my shirt and run itself across the deep ridges of my abs.

​

"Undefeated, huh?" Her words were sultry, "Want to play one more, maybe give me a few pointers?" I nodded, and started racking the balls. Already I could feel the effects of the drinks beginning to wane. "You want to make it interesting?"

​

"What did you have in mind? I'm not just going to take your money" I replied with a wink.

​

She chuckled mirthfully. "No no big boy. Nothing like that." She had turned from me to look me in the eyes. "I know what you want." Her quick glance downward told me all I needed to know. "But you look like a guy who knows his way around a gym." I nodded. "If I win, you can be my personal trainer, of sorts. Help me pack on some muscle. How about it, seem fair?"

​

It did seem fair enough. It actually seemed like a really good deal, even if I might get hustled. A win-win. "Deal" I said and we shook hands. I broke again, this time with a striped green falling into a pocket. It wasn't as great of a start as last time, but I made it work. At first. But then it seemed like I just couldn't get a shot. Not like I was being hustled, I just couldn't seem to get my shots to line up. Before I knew it, the mysterious red head had all but one of his balls socked away while I still had four on the table. My attempt to put the Nine into the end pocket failed but left her with a perfectly lined up drive for the Seven to fall into the corner with a gentle tap. And just like that the Eight fell as well. I smiled, genuinely pleased with the game despite the outcome. "A deal's a deal," I said, sticking out my hand.

​

"Indeed it is," she replied. "And I think I'd like to get started now," she quickly grabbed my hand and shook it. I felt a sudden wave of dizziness overtake me, followed by an unusually warm, tingling sensation. I hadn't let go of her hand, but as I tried to move I realized I couldn't. The tingling started to spread even more as it seemed like paralysis set in.

​

Then, perspectives started to shift. First thing I noticed was that the woman I had been ogling all night seemed to be rising up on tip toes... only she wasn't. She was actually, truthfully getting taller. But then I realized it wasn't only that; suddenly the dark wood trim of the bar around me seemed to be getting higher, the ceiling moving away from me as I stood, frozen, shaking hands. She wasn't just growing taller, I realized, I was getting shorter. Fear shot through me but I was helpless. If it was fear that I was feeling at the realization that we were now almost eye to eye, it must have been true terror that ripped through me when I realized the arm I was shaking was now bigger than my own.

Glancing down I found my body collapsing into itself under the polo that had previously been pulled pretty tightly across my wide chest. Biceps that had once clung tight to the sleeves of my shirt now felt cold and drafty with all the air that could circulate around them now. But what had begun as fear, and turned to terror, now became panic and dread as I felt my jeans slip down my hips. Becoming increasingly baggy, the weight of my belt pulled them towards the ground while tugging at the elastic of my boxer briefs that were also too big. But the worst part was the feeling of emptiness in the crotch as I realized not only my body but my very manhood was becoming severely diminished. I glimpsed a puny penis that could not have been more than an inch or two before my shirt, now totally oversized, hung down far enough to cover it.

​

Suddenly I feel a shadow fall over me. Caught up in my own transformation, I hadn't realized that I could move again. Or what had happened to the woman. The towering red head loomed over me, the blue dress that had fit so well now stretched and bulged. I could make out some tiny tears at the seams, where her bust had expanded substantially.

"Oh yeah," she said, flexing a bicep that bunched up even larger than mine had, "what a great lesson." The power in her voice made me shiver.

"What... What did you do to me?" I asked in a voice that was a high valsetto imitation of my previous bass.

"Only what we agreed on." She smiled at me from what felt like the stratosphere. She went back to the rack and pick up two pool cues, brandishing them in my direction. "What do you say, double or nothing?"
