Maybe it was because he had no memories implanted of Rose and The Doctor doing anything like this, or his mere hours of life so far, but it took John a bit longer than it should of to guess what she was up to.
This was seduction, he finally realised with surprise. But why him? Why now? He quickly searched in the jumble of information he had inherited for how he was expected to react to this.
There were deeply buried memories shut away and hidden. Images of unwanted kisses, of submitting to caresses from others that were not welcomed but rather endured for the sake of not hurting their feelings or out of fear of losing them.
There was nothing to prepare him for the touch of the woman he was born to love.
He knew this was supposed to be pleasurable, and something to be enjoyed but it didn't feel that way. He felt uncomfortable, uneasy and the urge to push her off and run from the room made his head pound.
Rose sensed his hesitation and let up her assault on his mouth. Propping herself up on her elbows she looked down at him, "what's wrong?" she asked, a frown on her face. She had never had any man not fall under her spell when she set about working them into a frenzy.
Scrolling through a series of replies John finally decided on the truth, "I don't exactly know what I'm supposed to be doing."
Her jaw dropped and she stared at him for a moment in silence. Just when he felt about two centimetres tall and wanted to crawl away and hide, she started to laugh, "I forgot! Now I feel kind of like a paedophile," she giggled. She rolled off of him, "I'm sorry, maybe we should just forget it."
Feeling a mixture of relief and fear that he had somehow disappointed her, John said nothing.
Then Rose reassumed her position of lying on top of him, "or you could let me teach you.." she smiled widely, her eyes shining down at him, "and with me to guide you, I think you'll be a quick learner."
This time she was more gentle, not as insistent. Wanting to awaken passion in him, not make him shrink back into the bed as he had done before.
When she kissed a trail of warm, wet kisses down his long neck and took the soft flesh where it met his shoulder into her teeth for a teasing nip she heard him take in a sharp breath and she smiled. It was working!
Pushing his red tshirt up to expose his chest she fixed her mouth on one of his nipples and he arched up with a gasp, almost unseating her. She locked her legs around his thin waist and held on tight.
Glancing down she noticed that his hands were clenching and unclenching at the sheets tangled around them, deciding those long fingers needed to be put to better use, she grabbed his wrists, and guided them to her breasts, to cup her.
Again he didn't know what she wanted of him, which she found both frustrating and if she were honest a bit thrilling, She covered his hands as much as she could with her smaller one and gently squeezed them around her.
The look of surprise as she did this made her want to giggle, but knowing that it could be misinterpreted as laughing at his inexperience she swallowed it down. Leaning back she rubbed herself against him, wincing once as her thigh hit his sharp hip bone.
Mistaking her expression of discomfort as being the result of something he was doing, John let go of her and started to apologise. She put a finger to his lips, "I just forgot how skinny you are," she replaced her mouth for her digit and thrust her tongue inside him. Try as she might, she could not ignore his initial reaction to this; he jerked back and made a slight gagging noise, but she was not going to let this stop her.
She laced her fingers in the soft hairs at the nape of his neck and held him in place. Her tongue plundered his mouth, while her other hand snaked downwards and rubbed at the not-yet-hard part of him, hoping to change this and finally get what she wanted.
