Surprise!

     I was minding my own business one day and then my sister Lauren came in my room with a silent giggle that worried me. She locked the door and that's when I tried to run away...with no prevail of course. She tied me into a chair and then taped my mouth shut. She pulled a large mirror in-front of me and smirked, "Guess what little bro? I'm going to turn you into a girl!" I panicked a bit and screamed under the tap, but no sound came out. 

     She poked my forehead and I saw my body suddenly shrink as my face became quite feminine and girlie. She stepped behind me and poked my hip as they bucked out and a loud slurping sound came out as I felt a lot of pleasure between my legs. I could tell that my manhood was gone because the bulge vanished where it was supposed to be. She then slid her finger across my chest as breast pushed out under my shirt. I started struggling to get away as she laughed, "Now I have to punish you for resisting!" 

     She groped me from behind and my breast grew slightly. The pleasure made me moan but nothing came out because of the tape, I panicked a bit not knowing how to deal with this as she just laughed louder. She ran her fingers through my hair as it started to grow down until it stopped below my shoulders. She poked my nose as my eyelashes grew more in length. She giggled and poked my chest as a black dress formed that cut off at my mid thigh. 

     I thought it was over as she hugged me from behind, with a sly smirk, she uttered on last thing, "Let's make this permanent, Little Sis!" I struggled to get away as she poked my forehead one last time. I felt a tingle go down my body. I went wide eyed, I knew what she did. I'm now a fully fledged girl...
