Yes - I have .

With a sigh, I quickly finished breakfast and hurried to Professor Ren's office, hoping not to be late for class. I entered the office, deciding to demand he remove the curse.

"Well, Granger, I see you've been enjoying the curse. I notice you haven't reversed the side effect yet," said Professor Ren.
"Wh-what side effect?" asked I.
"Can't you feel it?" he asked.

I thought to myself, seeing if anything other than my boobs felt different. Then I realized what it was. My boobs. Both of my boobs were vibrating as if they were going to burst. Ren took bottles from under his desk and looked at me.

"Each time you get cummed in, your breasts fill up with more milk. So we're going to have to milk you. One drop more in that pussy of yours and I can guarentee your breasts will shoot a large amount of milk into your bra and you'll be completely wet and stained," said Ren, as if it was not his fault one bit.

"Now, I will remove the curse if you allow me to put a new curse I just developed on you. Of course, if you like the curse, you can always keep it but either way I will be adding more," said Ren, passing me the bottle. I sighed as I derobed myself exposing my breasts and put a bottle on my right breast. Giving it a slight squeeze, at once milk began shooting out into the bottle. I quickly filled two bottles with each breast, my breasts decreasing back to the enlargened stage they were at when I woke up.

"Now, since I don't have any class right now I'll have to empty my load in you and add that new curse," he said, and I sobbed as he began sticking his hand in my underpants.

I breathed heavily and writhed under his expert touch, and before long I found myself stripping him and initiating sex without him even asking.

After several minutes of screaming pleasure we both came and I felt my breasts become slightly heavier.

"Now for the new curse," said Ren.
