"Kyle, we really should stop," the woman said with hesitation between soft moans. "I shouldn't have let this get this far. This isn't who I am! I'm your professor, for god's sake!"
"Are you really sure about that anymore? You don't look very much like Dr. Peters to me." Kyle smirked as he thrust harder, wrapping his arms around her. The woman stammered, unable to protest with the intensified distraction.
"No really," she gathered her resolve again. "This will all be over as soon as I get the parts for the machine..." Her eyes rolled back as she felt his tongue on her breast.
"Oh please," he laughed. "You could have fixed it weeks ago. You're having way too much fun in this hot new little body of yours. It's time to stop pretending, Professor. You should just admit that this is what you were after all along and we can just have fun with it."
She couldn't think straight enough to bother denying it. She felt the last of her resistance crumble away, and came harder than she ever had before.
