"Okay" I said. "So what's this idea you have?"
She walked up to me, swaying her womanly hips and biting her lower lip. If I had a cock at that moment it would be standing at full attention. "I want to dominate you" she purred. "I've always dreamed of being powerful and towering over my lover. I want to be over six foot tall and built like a truck."
I focused on the wish, trying to get it just right. She'd been more than willing to help me explore my lesbian fantasy, so I figured giving in to hers was only fair. Besides, I was curious as to what she had in store for me. She grew to almost seven feet tall with the muscles of an Olympic athlete. We both rubbed her arms and legs to feel the firmness of her new build.
Suddenly, she pinned me to the wet ground. In my female form, I was just about five foot even (when I wasn't having fun shrinking). Cassy leaned in and started agressively kissing me, holding both my arms to the floor with one of her huge hands while the other fingered my still dripping slit.
"One more thing, sweety" she whispered in my ear. "Make me a man so I can fuck that little pussy you've given yourself". I gulped. On the one hand, I was still a man in my mind. I didn't mind her having a little fun with me, but I didn't know if I was willing to go that far. On the other, I had made her far stronger than me and she had me in a position where I couldn't really resist her physically. I decided to just give in and go for it. The experiences I was having in this female body were turning out to be better than my wildest dreams, so why not enjoy it to its fullest?
"I Wish Cassy would transform into a guy" I finally said. Cass let go of my arms and stood up. Her breasts receded into well toned pectoral muscles. Her hips pulled in and her shoulders wiedened, but the biggest change came with the eight inch cock that slid out of her. I laid there, mesmerized by the glistening appendage of the cheerleader as her transformation reached its conclusion.
She picked me up and moved me back to the benches by the lockers. My heart was pounding like a jackhammer. Maybe it was the hormones my female body was generating, but Cass had turned into a total hunk, I had to admit. As she, I mean HE sat me down on the bench and raised on of her powerful legs, that massive new tool was presented to me.
With the slightest hint of hesitation, I took it into my hands. Cassy gave a very masculine grunt as I started jerking the shaft. It was odd pulling at one from this direction instead of from my own crotch. I remembered a bit of discomfort from some of my past girlfriends being too rough with my cock, so I stopped for a moment to spit some saliva onto my fingers.
"So this...Ungh. This is why you guys love this so..ungh...muuch." Cassy said huskily. Her voice as a man took a bit to get used to. It was deeper and more gravely than I thought it would be. I didn't have too much time to think about it because I felt a large hand press against the back of my head and draw me towards that waiting cock. My lips parted of thier own accord and I felt the tip of Cass' cock against my tongue. I tried to remember how I had liked getting sucked off and remember how one ex I had had in particular used to be able to drive me wild with her mouth. I continued to work Cass' (Or would it be Casey's now?) tool with one hand while massaging his balls with the other. Once we picked up some tempo and I was able to get more in my mouth, I was thankful that I had wished us both devoid of pubic hair seeing as I would otherwise have his bush in my face as well as his cock down my throat.
Suddenly the phallus was withdrawn from my mouth with a pop and I was pushed onto my back on the bench. It was surreal looking down over breasts and a pussy from this direction. I'd experienced lesbian sex just minutes before, but the big, bald throbbing cock being placed at my entrance made it really hit home that I had become a woman. I braced myself against the bench as Cassy slid into me. Bells and whistles were going off in my mind like the fourth of July as I was truly fucked for the first time. After the first few thrusts the initial discomfort subsided and a wave of feeling came over me that made my recent saphic escapade pale in comparison. Cassy was grunting with his eyes almost roled back into his head and a big silly grin.
"I kept hearing somemone saying "fuck me, fuck me, fuck me!" over and over and it took me a moment to realize it was coming from me. I started bucking my hips and grabbing his ass trying to get more of the cock inside me. I was a woman possessed. I wrapped my legs around him and drew him into me just as he started spurting his warm goo deep inside me. I looked up at Cass and pulled his head down to kiss me.
Then we noticed faint whistles and catcalls coming from the locker. Looking up, between the ventilation slots of the door, I could just make out the other cheerleaders from earlier watching us. Cassy opened the door. The diminutive cheerleaders had managed to get out of the box. One of them, Amanda, I think her name was, was knelt down between another's legs, lapping at the girl's pussy before casting a glance back at us.
"Mmm, looks like you two are having fun. Why don't you change us back to normal size and we can join in?
