I remember that I had a lecture in an About 45 minutes. I turn off the PC and unplug the machine, I hurry to put to put on a pair of size-XXL pants to cover up my udder and my womanhood, I put on a loosely hanging white T-shirt and a hoodie. I grab the machine and my laptop in case I find a way to fix my "problem", I put on some socks and shoes and call out to my room-mates, "I'm going out guys, be back soon", "ok, see ya" one of them replies. I hurry to my car, put my stuff in the passenger seat and drive off. As I'm driving, I feel I slight tingling but I just dismiss it and keep driving. Little did I know that I was still changing. I reach the auditorium with about 5 minutes to spare. I rush inside and notice that there is a seat at the back next to my best mate, Darcy, Just as a I reach him and sit next to him he looks at me and says, "hey Joan, you just made it, thought you weren't coming, how were the jocks?", "pretty ok" I reply as I get comfortable for a boring lecture, and just when I get comfortable our history teacher, mr Shultz, walks in and begins the lecture, about 10 minutes into the lecture I feel the tingling sensation again, but instead of all over my body, this time just on my chest. I put my hands to my chest only to feel them swelling from an A-cup to C-cup breasts and almost instantly I feel the tingling move to my butt. "Please don't grow" I think as I look at Darcy, he had not noticed any of this. Luckily the tingling did not change my butt, but it did change my legs, I feel the tingling go down my legs and finishing at my feet. My legs become instantly stiff as I feel my legs and feet slightly expanding, I put my hand to them only to feel that under my pants was pure muscle. I feel a strip of fabric appear on my breasts, I put my hand down my shirt only to feel a soft light bra on them. I begin to thirsty, Darcy seems to notice this and hands me what looks like a straw on one side that splits into four near them end, "here" he says very quietly with a smile "It's a self drinking/milking straw, I was going to give it to you later but here". I mouth my thanks to him, I pull out my udder and attach the four sided side to each of my teats then I put the other end in my mouth and begin to suck on it and at the same time feel myself being milked, waves of happiness flood over me as I feel myself being "relieved".
