Our TG Caption

Your roommate tells :
"- This isn't extreme enough yet. You don't even have big boobs ! You need at least a D-Cup and sexy lingerie !"
You gasp as you see the "Breast Size" section of the card changing from A to D. You then feel a pain in your chest. A pair of big boobs suddenly comes out of it. You're schocked but you suddenly feel cold and realise that your clothes turned into just a bra and a pantie. You feel really exposed and you don't like this.
You start to fear that your roommate will turn you into his sexual slave so you try to find a way to stop this shenanigans.
