Cautiously and prudently, at first

Linda twitched in surprise, but took a deep breath and **** herself to be calm. She had no idea where her doppelgänger had come from, or how she'd ended up in her bed, but the obvious way to find out was just to ask. And that meant waking the stranger up.

She reached over and shook the other woman's shoulder. As she did, the world seemed to shift around her; this was a really bad hangover. She lost her balance, and fell, her head striking a glancing blow more surprising than painful, and with that, she woke up.

Linda's first assumption on feeling properly awake was that she'd be alone in her bed, but instead, once she'd sorted out her eyes and limbs (was she still seeing double?) she saw two of herself: the stranger with the amazing body, and another one that looked more like she was used to. Were there suddenly three of her, or...

She raised a hand, and formed a fist. She saw herself do it, but also watched on of the other bodies do the same thing at the same time. So, she somehow was in control of both of these bodies. On the one hand, that meant she wasn't any closer to answers, but on the other hand, it meant she was alone and she didn't have to be shy.

She threw off the covers and looked down at her cock with four eyes. Suddenly, a fog descended over part of her mind; it was like part of her had forgotten how to think.

Linda found herself mostly in her new body, staring at her original body, which had gone blank-eyed and drooling. She tried to remember how she had moved parts of that body, but the mental fog damped her efforts. As she strained to **** her body to do something, she made out a droning refrain, a thought, perhaps.

"Obey... cock... Obey... cock..."

Well, nothing else this morning had made sense, perhaps her cock was hypnotic, whether she wanted it to be or not. The most sensible thing to try, speaking loosely, would be to test it out. "Um, get on your knees."

The mental fog thrummed with energy. An order! And one that felt simple and natural to follow!

Linda watched her original body fall to its knees and look up blankly at her. The sensations brought on by such a simple exchange were unexpectedly intoxicating; Linda felt both sides of it, the absolute submission of her original body, and the utter dominance of her new one. This was so fucking hot, and her dick was painfully hard. She walked up to herself. "Suck."

Her erection was enfolded in a warm embrace. She was devoting her being to the only thing in the universe that mattered. She was all-powerful. She was free of the miserable burden of choice. She was about to get the orgasm she deserved. Her needs were irrelevant and insignificant.

"Oh yeah, take it! Take—" the fog lifted, and she was in control of both her bodies again. Blushing, she walked her new body to the bathroom, to clean up her now-soft dick, and get a towel or something to cover up with.

Well, she wasn't sure what to make of all that. At least her cum tasted all right.
