"You're as beautiful as before," he said as he looked intently at her naked body.
The Doctor tried to regulate her breathing. He started at her feet and worked upwards. When he was done, he tossed the washcloth aside. She felt a sinking twinge of anxiety as he remained kneeling, stroking her thigh with one hand– she couldn't see the other.
He looked up and caught her eye. She let out a shaky breath, willing herself to make a decision.
Either accept that he's doing this because he cares about you or tell him to stop.
Okay.
"Don't–"
He leaned forward, unable to hear her surprised moan in detestation, and kissed her inner thigh. He caught her off guard.
Jack stood and held both of her hands in his. He touched his forehead to hers, "I missed you."
She hated when her friends and companions said things like that. Her face went numb. Their breath intermingled with the steam, bouncing off each others' faces, as Jack slowly closed the gap between them. He grabbed the back of her neck and kissed her.
As the kiss deepened, she almost felt as if didn't understand what was happening. Nothing was happening too fast; he wasn't forceful; she wasn't bound, hurt, or blinded; and, most importantly, he almost loved her. Yet she couldn't help but feel baffled by the entire situation. She remembered her first work assignment so long ago and fought the irrational fear of electrocution.
"Jack," she said between kisses, "I don't think I'm–"
She felt him sink into her, pressing himself against her, pushing her back to the cold tile wall. He was sure that if he could get her to relax, she would be back to the spunky, high-strung traveler he once knew and loved. The thought excited him. She felt his arousal on her lower stomach.
The Doctor looked past his shoulder and caught sight of a necklace hanging on the back of the bathroom door. It somehow snapped her back to the present. She was in her TARDIS, not the prison or some off-site work assignment. Her TARDIS, a fortress so far impermeable to every attack thrown its way. She would protect the Doctor just as she always had, all she had to do was ask.
"What is that?" She mumbled quietly to her TARDIS. Just as she finished the question she knew the answer. She remembered. It belonged to Yasmin Khan.
The Doctor pushed Jack backwards, eyes fixed on the necklace, and stumbled out of the shower. She darted straight to it and examined it closely, allowing water and suds to puddle on the floor. He grinned to himself; he'd seen this look before.
He stepped out and placed his hands on her shoulders, "Yours?"
The Doctor jumped. "Oh, uh…no."
Lost in her thoughts, she left for her bedroom and locked the door behind her. Jack sighed and grabbed a towel.
