You might think that I'm foolish for accepting the challenge but I thought I had a good chance. It all started with a conversation at the gym, I was pretty well built admittedly. My friend Dale and I were working out when we got into a conversation about those X-Change pills that are all the rage, laughing about voluntarily becoming women and the weird other effects they have. Anyways that conversation trailed off when Dale laughed and mentioned something brand new.

"So recently I got my hands on these new pills, their called the A-B pills, they are like a party popper" he laughed "basically they are known as Alpha Beta Pills, they match and when eaten the two people will have their bodies altered, the one with the alpha genetics becoming bigger and more buff, the person found to be the beta of the two becoming well a beta to be used by the alpha, supposedly it uses X-Change to guarantee some favourable changes" he jokes, I was honestly boggled by his unbelievable explanation, but I nodded along.

"So basically a couple unmarked party drugs that you think will make you a slut for me" I joked as I finished up my set and made my way home, Dale coming with me since we were going to chill out at my place. When we finally got there he mentioned the A-B pills again and I shrugged, thinking it was silly that an X-Change pill could tailor you to another person's interests since they are meant to just flip your chromosomes or whatever.

"Ok dude, I bet they are just party drugs or whatever, we might as well get high if we are chilling out anyways" I said as I accepted one of the pills from his hand. We both took the pills, washing them down with a quick drink. Then we fell into a long silence, usually we would be chatting about whatever but there was a curiosity in the air, firstly if they were genuine and secondly who the beta was.

I started feeling a sensation in my shoulder and chest, my core feeling tense as I started breathing heavily, I reasoned that I was gaining muscles and was the obvious alpha between us, my thighs feeling an intense strain as I reached me hand down to it to check, me palm sinking into the skintight pants as I looked down and saw a perfectly manicured hand, it was in that moment that my heart dropped, I realised the pills my has saw me as the Beta, I turned to Dale feeling the gentle sway of my growing breasts.

"You cheated somehow, I should be the alpha" I said in my feminised voice a soft moan escaping my lips as I felt my crotch pulling in as I had truly become female. My chest was heavy and huge now, I could tell I looked like a slut but catching white hair falling past my eyes prompted my hands to check up there only to find my ears had shifted into a tall pair of rabbit ears, I gasped hearing Dale laughing.

"Damn you really became a fuckbunny" he laughed reaching down towards my curvy rear, his hand stopping as his grabbed something unexpected and squeezed as a long erotic moan oozed from my lips, he was grabbing my rabbit tail, it was so erogenous I almost past out from the sudden orgasmic feeling. "Damn you really became a total Beta Bitch moaning like that when a dude squeezes your tail" he laughed as I felt my face heating up, I could feel myself blushing but his condescending words were getting me riled up and honestly the more I look at his tall, muscular and buff body I feel an unusual heat building in me. A blush came over my face as I realized I was fantasizing about what my 'Alpha' might do to me.

"Geez dude, how long do I have to be your little slut" I said my voice echoing a lust I wanted so bad to hide away, I found that I couldn't keep away from him, pressing my big breasts against his chiseled body, I knew that I was about to do whatever he told me to. He gripped the back of my head and pulled my head to kiss as he kissed me, my soft lips taken by his roughness I could feel my yoga pants growing damp. As he held me close I felt like what I could only describe as 'his little bunny', my mind shifting between why I so willingly called myself 'his little slut' and how amazing it would be to bed to be treat as his personal fuckbunny, thankfully I didn't' have to wait too long as his manly voice echoed through my body.

"Why don't you get on the sofa and show my how much of a little fuck bunny you are" he stated, it sounded like a suggestion but to my little Beta brain it was a command, I was panting like a dog in heat as I climbs on the soft and stuck my ass out for him. The fact I still have my yoga pants on didn't deter him as he approached me and tore a hole in the yoga pants pressing his dick to my pussy, I noticed myself gyrating against his dick trying to get it to enter but before I managed to make it happen myself he gripped my hips with his manly hands and forced himself deep into my wanting pussy. My tongue fell from my lips as he used me like the little bitch I am, the aggression making my legs feel weak but his strength kept me as his ideal height, I could barely control my mind as I vapidly took his dick inside, soon enough I felt a hot load filling my pussy, a sharp slap to my ass was quickly followed up with "now climb on and ride like the little breeder you are" he said laying back on the sofa ready for me.

I couldn't even attempt to think straight as I pounced his cock, pushing my pussy down on it to the base before pressing my hands against his hard chest and started bouncing on his dick like I wanted a full litter of babies, I honestly didn't even notice when my clothes had been removed but the way her was kneading my fat bunny slut tits just drove me over the edge as I whited out, my pussy full of his cum.

"Oh my little Beta Bunny Bitch is waking up" he laughed as I stirred from my sleep, I felt rotten, my head was aching, my body was sore, but thankfully I was back to myself, of course nude on my sofa next to my friend but I was myself. "You really got into it back there, so much for being an Alpha, the moment you took the pill you became a total cock whore" he laughed, it was annoying but I did feel good, the only annoying thing was that my dick was hard thinking about it and he could see it. "Thinking about taking another pill already" he teased, I blushed wanting to tell him to eat a dick but I think that I actually wanted to eat his dick, only after another A-B pill of course…
