Becoming one

"Oh god, don't stop!" Lisa moaned as Jack's tongue continued its dance with her citreous. Encouraged by her moans, Jack knew from experience she was close, very close. Suddenly her head snapped back and she screamed in orgasmic bliss, "Oh god Jack, yes, Yes, YES!!!!!!!!"
Jack felt her body snapping taunt like a steel spring. Her back arched, her toes pointed and curled, her finger nails drove into the sheets of the bed, her hips spasmed and soon her entire body began to shudder. Jack eased back, knowing anymore stimulation now would be to much for her. He untangled himself from her legs and moved up onto the bed with her. She was spent. Her eyes were glassy, her hair was disheveled and her entire body seemed to glisten from her arousal. At that moment, he had never seen her look more beautiful.
Lisa's eyes lowly focused up on her husband and she smiled at him serenely.
"That was the most amazing thing I've ever felt." She whispered with an honesty that frightened her.
Jack leaned forward, their lips meeting and instantly their tongues meet. Lisa tasted her own arousal in her mouth.
"This is what Lisa tastes like." A part of her mind thought as she felt Jack's hands on her body. "No, this is what I taste like." She thought feeling Jack's hands on her breasts.
She felt Jack shifting his weight so that he could be on top of her, and she remembered how wonderful that had felt the night before, but she gently redirected him so that he was on his back. It was now her turn to be on top, so she swung her leg over him, straddling him. Looking down at Jack, she felt power and control, and most of all need. She leaned forward and kissed him long and deep, and as she leaned back, Jack hands fondled her breasts. Reflexively her hips rolled forward and slide along the shaft of Jack's erect member, eliciting a moan from her lips. She reached down for his member, but fumbled with it and slid along it again. Sudden panic flashed through her mind realizing that for all intents and purposes she was a virgin, and she didn't want to let make a fool of herself. Not here, not now. She rose up her weight on her knees, hoping that Lisa's muscle memory would take over somehow, before Jack could notice anything was different. Reflexively she reached her hand down, gently clasped Jack's member and guided into her as she sank back down.
Both Jack and Lisa moaned with pleasure as their pelvis meet and Jack sank into the core of her being. She shuttered and tingled with excitement, feeling this new and delicious sensation. She was so lost in the feeling of it that she didn't eve realize that her body had now taken over, instead she was just enjoying the feelings she was receiving.
Rhythmically, she road Jack, feeling the delight of it. She felt perspiration forming on her body, running down her back. Jack had moved his hands to her butt and was now partially controlling her rhythm, encouraging her to go fast, which she was happy to comply. Her breasts bounced and swayed and she heighted her pace. Clasping her hands to them, she squeezed them eagerly and moaned as she felt the orgasm building inside of her. As she rode, her legs began to ache, but she wouldn't stop, she wouldn't slow down or even hesitate for a second as she felt the 'bubble' inside her about to burst.
Suddenly Jack tensed up beneath, moaning loudly, his hand firmly holding her hips as he thrust upwards, into her. She looked down at her husband and as if on cue, the bubble burst and she screamed out in ecstasy as the orgasm rocketed through her body. Panting and sweaty, she continued to ride him, slowing her pace as the waves of bliss faded from her body. She lay down on top of him, making sure to keep him inside of her, kissed him. She felt Jack becoming flaccid inside of her, until she let out a soft moan of disappointment as he finally slipped out.
They lay in the wet and sticky afterglow, staring into one another's eyes, smiling. Jack's eyelids started to look heavy and she smiled as they slowly closed and he feel asleep.
She lay there for a time in Jack's arms, feeling complete in a way she had never felt before. She had certainly never felt this way when she had been James.
Suddenly a cold shiver ran down her spin and she turned to look over at the digital clock next to the bed. It read 6:58. The numbers became blurry and she blinked and felt tears running down her cheeks. She blinked again and more tears ran down her face as the clock changed to 6:59. She leaned forward and kissed her sleeping husband, fighting back a sob.
Slowly she worked her way out of his arms and silently slipped out of bed. Hurrying to the bathroom, she cleaned herself up, making sure to brush her hair and make herself look presentable, but the tears continued and weren't stopping. She washed her face and quickly got dressed.
She had to go meet with Lisa. She wasn't sure what she was going to say. She was prepared to beg to remain as she was, to stay Lisa forever, but she was terrified by the very real fact that Lisa would most likely want her life back. And so she'd have to go back to being James again. Would that even be possible? Could she go back to being a man, especially after what she had just done? If she couldn't be Lisa, what would she do? She'd still have the medallion, so maybe there were other options, but the thought of not being with Jack was tearing out her heart.
She washed her face one last time, got into Lisa's car and headed 'home' to James' place.
