Jim groaned low at the sight of Bones coming undone like this. He shoved down his jeans, stroking himself once before pouring more lube over his cock. It was easy to lean over Bones, lining himself up and pressing himself in. Bones was always so tight, so hot around him, that it never failed to make him lose himself in it, staying still and buried.

"Fuck, Bones..." He leaned forward, knees spread, holding onto Bones' sides to keep himself up.
