Derek never thought he would find someone so compatible with him sexually. He knows that he can get a little intense, a little rough and bitey sometimes, but Barry seems to love it. He meets everything Derek gives him and asks for more, and Derek cannot believe how lucky he is.

Except maybe right now he can, because Barry is naked saved for the boxers tangled around his knees, groaning and writhing against Derek's body. He's just as desperate for it as Derek is, and he sucks another bruise at the junction of his neck and shoulder before tearing himself away. There's lube in the table near the sofa, and Derek retrieves it before stripping himself of the rest of his clothes. Barry's underwear goes flying somewhere and Derek grips the backs of Barry's knees, sliding them forward so Barry has little choice but to rise up onto them and lift his ass into the air.

Slick fingers tease at Barry's entrance, and Derek presses his blunt human teeth into Barry's hip as he presses one in. Tight as he is, Barry's body opens for him easily, and it's no time at all before he has two fingers working in and out of him, pressing in hard on the spot that makes Barry shake. "Mm, you gonna vibrate for me once I get inside you? I want to feel it around my cock."
