Ragnar's hands are on Sinric's hips, pushing and pulling and angling so they find a rhythm together that is the most pleasurable to them both. Despite being in the throes of pleasure himself, Ragnar still aims for Sin's sweet spot -- whatever cut off his balls did not rip out the prostate as well, and Ragnar knows that Sin can feel pleasure inside. He shall have as much of it as he can, even if he can't come again, as a woman would.
