You get dressed with more than a little bit of difficulty. For starters, you hadn't been provided with any panties (not that you were all too keen on wearing those at this point in your transformation) and you learned very quickly that your own underwear simply wouldn't do. Boxers you tried were immediately shredded by your humongous ass, and any briefs you tried turned into a sort of thong. You did stop to admire your ass for more than a few moments, especially while your briefs were flossing inbetween your gargantuan cheeks. But after a little booty wiggle you shook off your enjoyment--it was a nice ass for sure, but not while it was on you. You were determined not to like this situation, and you really couldn't be blamed. Especially, it seemed, when you realized that you were going to have to forego underwear completely.
Sure, you didn't have any lady parts just yet (and you cringed at the word "yet") but having absolutely nothing between your amazing ass and a thin layer of spandex (which you knew would be stretched to where they were almost see-through) didn't exactly thrill you. Still, there was nothing you could do about it, so you took to the task of cramming your huge butt into a pair of black spandex pants. Once you had them on, you could immediately tell that the curvature of your new ass was just as visible as it was when you were naked, since the pants were damn near painted on. And just like you had guessed before, hints of your skin (which seemed to be slightly darker in tone) were visible all over. But of course there was the wedgie, which you quickly deemed to be the worst part. While it wasn't as bad as the briefs, you still weren't terribly excited about having one all day, especially when it made your cheeks appear even more prominent and defined. You pulled out the wedgie (no easy task) and took a few experimental steps around your room. A few things became clear: the wedgie was not going away, period, and you were going to have to become used to an absolute storm of bouncing, jiggling, and gyrating going on behind you whenever you made the slightest movement. Following up on that, you decided to see what it looked like when you bent over, so you positioned your ass toward your mirror (being very careful not to knock it over with your colossal rump) and attempted to touch your toes. The results were... less than ideal for you. The pants became all but transparent, allowing anyone who would or could look to see your big ass essentially bare. On top of that, the pants slid down a bit and more than a little bit of crack became visible near the top. You sighed. Nothing you could do about it.
As much as you would've liked to prepare yourself for your new life with the Hispanic junk now absolutely filling your trunk, you had to get to school. Your mom saw to it that you got there right on time, preventing you from trying to avoid people by coming either way to early or just late enough. You shuddered a bit while you entered the main hallway, but you quickly find that nobody even seems to notice your very noticeable ass. And it wasn't just that people didn't see you--you saw more than a few people look right at you and then simply go on with their day.
"Okay... so Isabella must've made it so people either think I've always had this... thing behind me or they just don't care. I guess I should thank her for th--" you start, but you're cut off a bit by someone pinching your ass. It wasn't all that gentle, either. "Well there's a lot of people here so someone might've mistaken my ass for their girlfriend's or something while they weren't paying attention. No big de--" Now, a squeeze. And not a little one, either. It was a handful, which on you meant a whole lot of ass. You keep walking, trying to deny what you now are becoming aware of. "No, no, no, this is not happeni--" Now, a smack, which sent a ripple of booty fat from one cheek to the other and elicited quite the gasp from you (which sounded more feminine than you were comfortable admitting). It seemed as though a group was starting to form around you, or, more accurately, behind you. What had been a few individual instances of people getting handsy was turning into an absolute grope fest. Your cheeks were being rubbed all over, squished together, bounced, squeezed, slapped and everything else you had ever enjoyed doing in your days as an ass man. You began to feel hot and dizzy, just as you had felt when Isabella cursed you. As everything became blurry, you managed to run into the bathroom.
As you saw your face in the mirror, you were shocked to find that you were actually blushing. You splash some water on your face and shake it off for a few minutes. After you seem to have regained your composure, you look in the mirror yet again. "I can't believe they were... grabbing my ass like that..." you trail off as you noticed that you were not only blushing again, but biting your lip (which looked a little fuller and more feminine).
At this point it was clear that Isabella was making you the same sex object that you had made her, and that the other students saw you (and, more importantly, your massive butt) as fair game. How do you react?
