Ms Saki has been your teacher for a few years now, and you have both been dating in secret for about a year, nobody knows about the relationship between you two and you plan to keep it that way for a long time, since she started dating you, she has been gaining alot of weight, due to the fact that you confessed to her you enjoy bigger women quite a while ago and she decided to indulge, and she seems to like it too, not even letting her new figure distract from her teaching that class your in, although she does try to tease you alot in class, but not making it too obvoius so others figure out whats going on, things like whispering strange things to you, and moving in alluring ways, you couldnt stop thinking about her, you were currently in her class now, she was at the other end of the room currently turned around and writing stuff on the board while talking, sometimes looking back giving you a few flirty looks, since she knew alot of the class wouldn't be paying attention anyway
