"On the other hand", she said, "There is one more thing, which you need to know."
I nodded for her to continue. "We have discovered another side to this glitch. If you choose to go for the pregnancy class, we can modify the cum-replacement to stop this, but you may choose to do this instead." I motioned for her to finish her sentence, my new tits wobbling against my chest strangely. "
"Every 4 hours, your tits will grow a cup size. This, coupled with the side-effect all of you got causing the milkiness, you can enter the Human Cow class. Strangely, this particular part of the Glitch only happened to you, but now you have the choice to enter the Human-Cow class after your tits have reached the size of the normal Human Cow Students. On the bright side, though we can't stop the glitch, we found that it will cause you to stop growing after your tits reach ZZZ."
I then felt something happen on my chest. As I looked down, I was just in time to see my boobs swell, growing from KK cups to LL cups. "See, It's happening already", said Ms. Smith.
"OK", I said, "I'll go into Human Cow."
"OK, then, I'll make the arrangements. Would you like a serum to speed up the glitch's progress?"
I nodded, and she smiled, and left the room.
