Stepsister Maya

Me player has a older wasian step sister Maya, we always help each other a lot. Last month she helped me getting over my ex, she truly did me a huge favor. We are currently living together mainly because she does cosplaying for living. She posts her anime cosplays online making us a fortune. I do all the photoshooting and image editing for her. Her beauty does a lot more my editing could. She has this beautiful long brown hair, beautiful face, big eyes, average boobs like a C cup i would say, slim waist, juicy belly, her butt is thick not big but thick complimented by her thick thighs that create a heart shaped back side, long legs to be fair i have a little crush for her. Well she still has not been to a cosplay con but i can just see how much she wants to go so she asked me for a favor. She wants to do a duo cosplay with me, but i will need to take the new gender transformation pill that will transfom me into wasian baddie as well. We are talking tall figure with beautiful long straight black hair, beautiful face, big eyes, big boobs really big that keep their firm shape even without support, thin waist creating a hourglass figure, big butt that pops out with big thighs that could pop a Mellon creating a heart shaped backside, long legs, puffy vagina and lips. After i take the pill my body will take 3 days to fully transform. We will be cosplaying two characters in their bech episode bikinis. And so i accept. But what she won't tell me it's that we aren't going to just a normal anime cosplay con. We will be going to a porn anime cosplay con. Basically you go cosplaying as a character a then get fucked in your cosplay in your own boot they select for you for like 4 hours by people that payed for experience of fucking cosplayers, basically me and step sister will become free use.( The transformation of the pill last exactly one week but if i enjoy myself too much on it my transformation extends by a lot, and if i enjoy it even more than my male experience it becomes permanent. She will only tell me about the truth of the cosplay con right after we enter the boot. I want you to describe my inner thoughs, experiences and feelings during everything that's happening. Also describe each step and day of my transformation, because during those days we will be preparing the cosplays)
