Deny her!

You decide to resist Alex! You jump back, and put up your dukes! However, you're surprised to see that Alex isn't frowning, but grinning instead.

"Oh, good. I was hoping you'd resist. We're running low on test subjects."

Alex reaches down to her pants, and a confused look runs across your face as a zipping sound echos throughout the room.

"And... I'm feeling kinda horny just looking at you. I'm going to enjoy fucking that mouth of yours, dearie." And with those words, Alex reaches down into her pants, and pulls out an ENORMOUS cock, semi-flaccid, about 2 feet in length. She throws off her uniform as well, and you watch in confusion as she strips herself naked, exposing her massive, perfect boobs.

"Ah... Now I'm ready to fight. Bring it, May! You'll soon regret your decision!"
