It started out as a typical day in class, with you sitting in the lecture hall along with your 50+ peers, trying to pay attention to the professor at the front.
The only difference that slowly dawned upon you was that you were sitting next to a different girl than usual. Of course, there aren't assigned seats, but usually people stick to the places they chose after the first day.
It would have been menial and nothing to think about, but it seems this girl was acting a bit... off. You recognize her from somewhere, but you're not exactly sure where from at the moment. You're sure that she was a fairly slim and attractive girl, but now she seems to have gained some weight as her belly was clearly showing skin as it pressed against her shirt.
Her behavior was odd as well, as you could hear her grunting and snorting under her heavy breathing as she wrote in her notebook. Thankfully, you usually sit in the back corner, so no one else noticed her sounds.
Without attracting her attention, you carefully and quietly lean to take a peek at what she was writing down. It comes to your surprise that she wasn't paying attention in class, as her notebook was being filled with 'oinks' and 'squeals'
That's when you remember that she actually lives in your neighborhood, specifically in the other house next to Butch and Trevor's house. Her name was Sarah and she used to be in a few classes with you in high school as well.
'I guess she's had more interactions with them than I have. Must have taken a liking to them.' you think to yourself, not wanting to disturb class. To avoid bringing any attention to yourself, you decide to pay attention back to the lecture, although it was a bit hard to focus with the quiet grunts and snorts coming from her.
