Molly kisses him back, feeling a shift in him from playful to thoughtful in an instant. But it feels like good thoughtful, not 'get out of your head, Sherlock' thoughtful. She can taste herself on his lips and it amazes her the shades of him she's able to see in mere minutes - from a bloody frustrating sexual prodigy one moment to a friend she can joke with the next, and on to a tender lover in the next. She thinks it's exactly what it should be like - this comfort level. It makes the next question easy and not awkward to ask.

"You have some choices to make here," she leads with as her hand searches and easily finds his erection between them, circling around it. "We can either have intercourse - you on top this time if you'd like - or I can perform fellatio. Or whatever you like, really....Well....within reason."

She's not sure how far his research has gone yet and if he's discovered any sorts of kinks. She imagines Sherlock will have kinks. He seems the type. Molly has a couple herself.
