'til the end of the line

It might be difficult for some to focus on the task at hand while Bucky has his mouth on them, his fingers inside of them, but Sylvie finds she can concentrate just fine. While what he's doing makes her shudder with pleasure, heat licking through her, her hips rocking against his face, she's never gone down on him before. It's rather easy, she thinks, to pour nearly all her attention into sucking his cock.

She pulls back, licking the head of his cock again, dragging her tongue around it, then sinks back down. Following her mouth with her hand, Sylvie's head begins to bob, slowly at first, taking Bucky deeper before backing off again, enough to suck just the head of his cock.

With her elbow braced on the bed, she strokes his balls at the same time, sinking onto his cock, swallowing around him, fingertips sneaking back further, behind his balls, stroking against the ring of muscle between his cheeks.
