No not as plump as your weight of 250 lbs, your sister had put on a considerable amount of weight since the transformation. She wasn't wearing glasses, nor did she really need to, but you could tell by her choice of attire that your sister had made several developments, along with the rest of the universe. She was decked out in rather geeky attire, with an anime related shirt pulled tightly over her pudgy frame, leaving little to the imagination despite the fact her cleavage wasn't showing. Her jeans were nothing special, not designer or fashionable, and were, for all intents and purposes, betraying her inner fan girl.
"Oh, there you are!" your sister stammered, rising hastily and clumsily to her feet as she approached you, a smile adorning her round, cherubic cheeks, "Listen, Melissa, I hate to ask, but do you mind if I borrow your boxed set of Evangelion tonight? A few friends of mine are coming over, and we wanna see it."
"Uh, sure, no prob."
"Great. By the way, great party last night."
"There was a party?"
"Well, if ya can't remember, I'm not surprised. I did have to carry you home. Not easy, I'll have you know. Ya need to stop packing on weight."
"You're one to talk."
"Only because Jackie loves my love handles."
"Jackie?"
"Geez, you are zonkered, arent you? My girlfriend?"
So not only was your sister a fat geek, but she was also a lesbian! This universe had it's perks, and Melissa wondered whatever interesting surprises awaited her at school.
