It turns her into a nympho

The Doctor smiled. "I don't think so." He pressed a button on the remote.

Instantly pleasure shot through Max's whole body. All she could think of was fucking herself. She struggled to free her hands, but in vain.

The doctor hit another button, and she felt something sliding inside her! It was almost like a mechanical dick had been hidden in the apparatus. She writhed in pleasure, then stopped as the motion ended.

As soon as the device was turned off, Max, came to her senses. "You sick fuck! What did you do to me?"

"Max, we finally found a way to get you to conform to our breeding protocols. Soon this device will be fused with your body so there will be no way for you to remove it."
