Vasquez's body is warm and tight around him and he's being urged on, which Sweeney can only take as an indication he's not hurting him too badly, so he rolls his hips back and then forward again, sinking deeper inside of him.

"Fuck," he breathes. "Do that again."

Because the sting of pain he feels at his ass being slapped sends tingling pleasure down through his body, along his spine and into his balls. Shifting on the bed, he loops one strong arm around Vasquez, lifting him slightly, angling his hips and then sinking deeper inside of him.
