Comic Con gone wrong

Today was the start of Comic Con and I couldn't have been more excited. I even went all out in my cosplay as spider Gwen! I just couldn't wait to get inside and show off.

That is‚ until I met a woman cosplaying as Captain Marvel‚ who went out of her way to give me a firm slap on the ass as she passed by me. "Nice ass‚ but that's all you really got, it seems." 

I glared at her and followed her inside the Comic Con building. "Hey! The hell is your problem? Slapping me on the ass and talking to me like that?!" She smirked and walked into the side room not being used‚ which I stupidly followed her in to.

The moment I was inside‚ I got kicked from behind and onto the floor‚ as she closed the door and locked it. "What the hell?! You have problems bitch!" I got back up‚ but gasped when I looked up at her.

"What's the matter? Haven't you ever seen a shemale?" She smirked while stroking her flaccid cock in her hand‚ completely taking me by surprise as I was left speechless at the large size of it. "Don't worry‚ I'll let you play with it~"

She walked towards me and I was shaking‚ as my loins started to grow wet from both fear and arousal at the sight of this hung shemale cosplayer walking towards me with that fat cock swinging like a pendulum.

I finally managed to move and took a single step back‚ but that was a mistake as she immediately closed the distance and put her arms tightly around my waist and kissed me deeply. I wanted to pull away‚ but she held me still and stared into my eyes as we began to French kiss like we were lovers.

I was starting to melt into the kiss‚ as my eyes glazed over a bit as I felt her throbbing cock pressed up against my lower abdomen and making my womb ache in the process. As I moaned into the kiss‚ I felt so empty, helpless and aroused now.

She broke the kiss with just a string of saliva connecting our lips now. "Mm~ You're going to be fun! Do you want me to fuck you?~ Just screw your brains out?~" I was panting heavily after the kiss and hearing these words had me grinding my thighs together.

"S-Shut up..! You're some kinda shemale freak..~" I struggled to remain strong‚ but when she held onto her cock and jabbed at my lower abdomen with that large tip‚ I moaned shamelessly like a bitch as my pussy squirted juices out from a spontaneous orgasm.

She walked up behind me while I was still recovering and ripped open the back of my suit‚ down by my thicc ass. "W-Wait don't.. I have a boy-Ahh!!~" My eyes rolled back as she shoved her fat shemale cock up in between my ass cheeks and deep inside my asshole.

"Gah!~ T-That's my ass..! Wrong hole w-wrong hole!~" I cried out in pain and pleasure‚ but she shut me up by hugging my waist and rapidly jackhammering up into my snug anus. My luscious lips only had moans leave them now as she thrusted with such force up my ass that I was actually barely touching the floor‚ my toes curled from the brutal ass fucking I was receiving.

I barely could think straight as she kept ravaging my asshole like her personal plaything. "I knew your ass was your best feature! Tch‚ I don't think you need to be a woman~ You'd be better as a cute femboy~" I didn't understand a single word she said,‚ as I was just lost in the sensation of her fat cock stretching my asshole out.

Soon, with each thrust, I was shrinking slightly‚ as my chest slowly receded into a petite A cup pair of breasts and small light pink nipples that poked slightly through my tight suit. She even reached up and started to tweak and play with my sensitive nipples, which made me whimper and moan like a total bitch.

"Heh~ And let's get rid of that pussy~" I went cross-eyed when she started to thrust harder then ever and have me leaning back against her with my feet completely off the floor now‚ stuck on her fat cock. My crotch grew soaking wet and I started to violently squirt juices through my suit's crotch,‚ making a mess on the floor as I had the strongest orgasm in my whole life. 

Little did I know‚ I was actually purging my body of estrogen‚, making me grow slightly smaller still with my ass being the only thing unaffected as it stayed nice and thicc as she fucked the woman out of me. 

I threw my head back as with a wet popping sound‚ I had birthed a small set of balls and a cute dick‚ as my womanhood was no more. "Ahh!!~" I moaned loudly as my new dick started to spew out ropes of watery cum‚ thanks to her cock bashing my new prostate. 

"I knew you'd make for a cute femboy!~" She moaned into my ear as she started to give my ass a hot cream filling‚, making me black out from the sheer euphoria. 

-a few hours later-

I woke up on the floor of the empty room all alone‚ groaning softly as I slowly got up and bit my lip as I felt my exposed ass jiggle. "Oh fuck.. it wasn't a dream~ Ooo~ I wonder if Erin will still be my boyfriend with me like this... I hope so~"

Whoever that shemale was,‚ I sorta felt angry‚ but also weirdly happy at the same time. Maybe it was my mind still trying to move past being fucked into a femboy‚ or me just being much more submissive now. Either way, I left the Comic Con with a smile on my face and ass jiggling out in the open still.

When I got home, it turned out Erin had a femboy fetish‚, so I went from being slightly worried to moaning his name as he pinned my smaller frame down and fucked my asspussy with no hesitation in a mating press position. 

I wished I could've thanked that shemale.. oh well, my life has been better since that day. Now I live happily as my boyfriend's femboy boitoy~
