Well, he must be doing something right to get that sort of reaction. Not that he doubted his capability, of course, but more that... Again, he wasn't sure that Rosie thought of him any sort of way. But to know that she does and that he can please her sufficiently, well-

He had more thoughts follow that but they're tugged out of his brain as soon as she makes contact with him again. Her forehead tips against his and gives him a good angle to bring their lips together for another kiss. Then, it's his turn for his lips to stray as he brings his teeth to scrape against the fair skin of her neck. He doesn't bite harshly, but suckles strong enough that it will leave marks. All the while, his fingers continue to pump in and out of her needing cunt.

When she asks for harder, it isn't difficult to oblige. Dimitri always tries to mind his strength because he knows how easily it can get away from him but- In this? He's never regretted following the command for more and neither have any of his paramours. "Gladly," he answers, muffled against her skin. He follows what not only feels right as she guides him but with whatever draws more noise from her. His other hand, meanwhile, acts as both anchor against her side but also reaching his fingers along the expanse of her ample chest where it can.
