James was stunned. It wasn't that Nicole was an overly dominant woman, or that she wouldn't gladly try sexual things for him, but being a willing slave was something else entirely. "Are... are you okay, Nicole?"
"Yes, my master!" she answered cheerily. "My master is doing well, and..." she shook her hips and tensed some unseen muscles, sending a momentary surge of pleasure through James, "and has rewarded his slave by allowing her to continue to have her warm flesh around my master's beautiful penis."
The vixen's cheery tone finally was enough to stir Joanna. The half-dragonness pushed herself clumsily to a sitting position. She blinked, staring at her clawed hands. Slowly, her expression became a smile, as she stretched both her arms and her massive wingspan. She tilted her head back, making a deep purring sound. "I can't begin to describe how much that hurt," she said, her voice deeper since the change, "but this is worth it." As her wings folded back away, she looked around. There was one more fox-woman than she remembered, but nothing else drastic seemed to have changed. "Looks like I didn't miss too much," she smiled. "Whose turn is it?"
James tossed the dice wearily at the board. He didn't want a slave. He wanted the give and take of real love with the real Nicole, and part of him knew that he no order he could give his slave would give him that. The dice skidded across the wooden surface, coming to a rest with both dice showing ones, just before falling off the far side. His next square was green. Animal changes. James realized with a start how lucky he had been. He was still human, after all. In fact, the only change he had experienced was the knot that tied him to his girlfriend. Until very recently, that had even been quite a bit of fun, he had to admit. But now, he thought ... now that would change.
A roll of two is snake eyes,
of that there is no doubt.
Yet it will not be your eyes that change,
but how you move about.
And change he did. James could feel a sort of sticky sensation between his legs, like trying to get up from a cheap plastic chair in the middle of summer. Nicole could clearly feel the changes, too, although she didn't say a word as James's genitals shifted, the knot dwindling away to nothing as his one length became two, and then retreated into a newly-formed vent. Maybe she thinks I'm punishing her, he managed to think. The sticky sensation intensified as his legs fused together, bones melting away and then being rebuilt in a more flexible form. He writhed on the ground, still largely held down by Nicole's weight above him. His new tail began to lengthen. The sensation was neither pleasure nor pain, but a strange feeling of become liquid and being poured into a new mold. Blue-green scales began to push through the skin, forming a protective surface on which he could slither, then spreading over the whole of his tail, and up past his waist. There they stopped, save for a few patches of scales that popped up like freckles about his arms and upper back.
He took a moment to take stock of himself. He could feel the power in the muscles of his new tail. They would support him, move him ... crush his prey, if he so desired. He was still James, to be sure, but James now sat atop twenty feet of reptilian power. He let a hand slide down past his waist. There was a slit there, a gap between scales pressed closed by powerful musculature. He slipped a finger inside and could feel the twin tips of a serpent's sexuality, as well as the deeper passage that had once had his ass as its home. Cloaca, he remembered, dredging the name for his new biology from some half-forgotten freshman course.
"Nicole," he quietly asked the vixen, as he slid himself out from beneath her furred form, "do you still love me?"
"My master's slave is his no matter how my master changes," she replied.
"Better than nothing."
