After the beam hit me I began to feel very strange. First of all it felt like a numbing sensation throughout my entire body followed by a feeling like pins and needles. The feeling started from the top of my head and spread all the way through me until every inch of my body felt like pins and needles. The feeling started to get more intense and I began to get concerned. Was it supposed to feel like this? I felt a sudden sharp pain in my chest then to my surprise movement. I looked down and could see that my chest was expanding!
My pec muscles must be growing I thought to myself but then I was horrified as I could see that I was growing what looked more like… boobs! “I think something’s going wrong!” I shouted out to Steve. My voice sounded strange all of a sudden, like it had become slightly higher pitched. Steve had a strange sinister grin on his face while he just stood and watched on. I was just about to shout out to him again when suddenly an immense surge of pain shot through my entire body like a jolt of electricity. I threw my head back before letting out a shrill scream higher than I ever had before. I fell to the ground on all fours.
I could feel the boobs on my chest hanging down. The pins and needles feeling in my body had turned into an unbearable throbbing and aching sensation. Suddenly my scalp felt incredibly itchy for some reason. Then I realised that my hair was growing! I could feel it growing past my ears, moving down my neck then spilling across my shoulders. What the fuck was happening to me? I looked up at Steve through the strands of hair that had fallen down in front of my face. I was confused to see that Steve had a very sinister grin as he watched on with immense satisfaction. He didn’t seem concerned at all, quite the opposite in fact. Why was Steve smiling? Was this normal? Was this all part of the plan? It sure didn’t feel right…
More pain shot through my body and I winced then screwed my eyes up tight as an unbearable sharp stabbing pain rose through my lower body. I could feel my hips expanding outwards as if they were getting wider. I let out a loud high pitched scream as the pain was excruciating because I could feel my bones moving and expanding. I knew Steve said the process would be painful but I never realised it would be this fucking painful. I felt faint, a film of sweat formed on my face and I could feel my long hair sticking to my forehead. This wasn’t right. This wasn’t right at all.
I began to feel a tingling sensation in my hands and fingers. I opened my eyes and looked down to see my hands shrinking! The hair on my arms was falling off too for some reason. My face felt colder as well, I saw all the little hairs on the ground below me and realised to my shock that my beard hair had fallen out! I felt my face with my hand, my face felt completely smooth and my hands seemed much dantier. I let out a gasp as a disturbing thought entered my head. The hair, the smaller hands, loss of body hair, wider hips and fucking BOOBS! I’m not turning into a body builder, I’m fucking turning into a WOMAN!
I looked up at Steve who was grinning devilishly and was almost salivating at the mouth eagerly watching my transformation. Oh my God. He was enjoying this. He was getting off on this! He wasn’t turning me into a bodybuilder. This was his fucking plan all along! The fucking bastard! “Steve, what the fuck have you done!?” I cried out in a completely feminine voice. I was startled by my voice, that wasn’t my voice, but it was the voice coming from my mouth. “What the fuck have you done to me Steve!? I cried out again partly in anger and partly because I wanted to hear the voice again, the woman’s voice, MY voice that didn’t sound anything like my voice. This was bad. Very fucking bad.
I began to feel a swelling sensation in my lower body then I realised that my ass cheeks were growing and expanding along with my thighs. Strangely my belly also began to grow fatter and I could feel it hanging down along with the boobs. Holy shit I felt fucking huge! My entire body felt heavy, I’d never been this big before. I reached behind and ran my hand across my ass, it felt massive! I didn’t recognise my body at all anymore. Fucking hell, how could this get any worse? Then it happened.
The pain was beginning to subside throughout my body and I thought it was all over. All of a sudden, I felt a surge of pain in my crotch as if I’d just been kicked in the balls. Next I could feel movement, it was as if my dick and balls were shrinking. Oh God no! I reached down and could feel my junk shrinking inwards then felt like it was splitting in half. I yelled out in absolute agony as I fell to the ground on my back. The pain was too much, I began to lose consciousness. I stared up at the ceiling as it began to become blurry. Then Steve entered my line of vision and looked down at me smiling lovingly. He softly said “Don’t worry babe you rest now. We have a big day tomorrow.” Then all went black as I passed out.
