Molly whimpers as he sucks hard on her nipple, her hips shifting again. It's torturous in the good way but she's impatient for his mouth to slide slower.

A couple things run through her mind as he tells her about his mastubatory history. One is that Sherlock knows the average number of times he masturbates in a year (of course he does) and two, Sherlock is actively telling her about it to turn her on. This is Sherlock Holmes doing dirty talk and it's wonderfully still him, not forced or something he heard in a porn. And it's working.

"What is it the kids say 'sorry, not sorry'?" she jokes, in between breathy pants. "You know, generally when you become involved with a sexual partner, you end up masturbating less."

Although she supposes that doesn't take into consideration having to be aware from your partner for any length of time.
