"All the power of that weird machine, and this is all you do to me?" I asked, feeling very odd, but that was probably due to the fact that I'd been just minutes ago. I looked up at John, WAY up, and felt another odd tingle, "The only crazy thing about this body is that I'm so short! Just how short am I anyways?" We'd been playing with the weird machine we'd found a few days already. We took turns, one person using the outside panel to design a shape, the other going inside and pushing a button, then POOF! transforming into that shape! When it had last been my turn, I'd used the machine to turn him into a dog for an afternoon. Obviously John making me a woman was some kind of payback, but I'd really been expecting for him to reciprocate in kind and for me to be a dog right now.
"Short enough." John walked over and stood behind me, making me feel truly, incredibly small. When he put his hands on my belly I shivered, but didn't pull away. Of course he wanted to touch. I'd pet him when he was a dog, so this seemed only fair.
"Now don't go getting too handsy. That would be weird." I said, shivering again. My whole body was tingling in a way that was making me a bit nervous.
"Weird huh? Like when you had me go for a walk and made me poop in public?" John's hands slid up my torso, bringing my shirt with it.
"Hey!" I protested, but still didn't resist. The tingling was more intense now.
"See, it was embarrassing, but I learned some things from that experience. Like how as a dog, if I didn't think about it, it really didn't bother me to poop in public. Just like how if I didn't think it about it, it didn't feel weird that the whiff of every bitch we walked past gave me a half a chub. That got me to thinking about how best to get back at you..."
"Wha-wha- what are you saying?" The tingling felt good, intensifying whereever he touched, and also...
"You feel it, right? Like you're not really you. Like you really are a tiny little woman who wants to be taken by a big strong man..."
"N-n-n-" Holy shit, I realized when I couldn't say the word. I DID want it, just like he said! The tingling... I was hornier than I'd ever been!
Without another word John carried me to the bedroom and stripped me naked. He rolled me onto my hands and knees, and I felt something MASSIVE probe at my drooling wet pussy.
"It's too-" I tried protest, but was cutoff when John thrust forward, proving me wrong. His cock wasn't too big at all!
He fucked me and I moaned desperately. Part of my mind roared that this was wrong, but I couldn't resist it anyways. It was wrong, but I wanted it. Why did it have to feel so good!? Why did getting fucked as a woman have to be the greatest sex I'd ever had?!
He flipped me to a new position and began to thrust more rapidly into me as he held my legs open. The pleasure I felt just kept building and I was sure I was about to scream or go mad - maybe both!
"Tell me you love it!" John demanded.
"I love it!" I screamed quite honestly. The feelings were so intense, it's not like I could've said anything else even if I'd wanted too. "Fuck me, fuck me, don't stop fucking me!" I begged, needing more!
My whole tiny body rocked with every thrust as I finally came. It was incredible. I couldn't breathe. I couldn't see. My whole universe was just to exist as a tube of slick flesh spasming around cock.
He thrust deep in me and I felt warmth fill me. Only as I slowly came down from the greatest sex-high of all time did I realize what that meant. He'd cum in me.
"So I take it you liked my revenge." John finally spoke as we both gasped for breath.
"I'm going to have to come up with something even better for you." I muttered, but already I was feeling something odd. The pleasant tingling was already coming back.
I was already getting horny again!
"But first..." I knew I needed to feel that way again, and I would do anything to do so. I rolled over and started sucking his cock, desperately trying to get him hard again.
His cock felt huge in my mouth. It tasted like pussy and sweat and cum and all of that blurred in a delectible sexual melange.
He was a bit surprised, but his cock eventually responded accordingly.
"I'm ready for you to get some more revenge..." I said when he was hard again.
Several intense rounds of sex later and I was barely able to walk. My legs felt like jello and my pussy burned with a dull ache when I tried to pull my knees together. I was more satisfied than I'd ever been in my life though. I almost felt bad to turn back to myself, but that was the deal so we went back to the machine for John to switch me back to normal.
... Only the machine didn't respond.
I was going to be stuck in this tiny, horny body for a long, long time...
