Chunky Nerd in Spring (Patreon)

It's the end of the school year and you see Alison, the girl from your Network security class, who you watched go from skinny-fat to past chubby over the last semester. Its your last chance to become more than acquainted before the summer break, and maybe forever if she doesn't come back.
 You try to work up the courage to talk to her about something other than servers but you're once again distracted by how tight her dorky clothes have become, fully showing budding rolls and exposing a sliver of pale midriff when, oh-no, she catches you staring, and you make meaningful eye contact. You see surprised confusion in her eyes and look away, wondering how much she saw in yours and how she felt about it, afraid and ashamed that you've probably made a nice girl just going about her day uncomfortable. You try not to make it too obvious how desperately you are fleeing as you rush to your next class.
