The gradual tempo as her hips roll against his, that ripple of pressure that he can feel as she squeezes her muscles just so around his cock -- damn it all she's good and he's loving this. Jack is unrestrained in this appreciation, too, breathing out a heavy moan and feeling a shiver tremble its way through his entire body. His hands work on her breasts in the meanwhile, massaging and caressing, brushing shapes over the sensitive flesh of her nipples.

Then her pace picks up and he can't seem to focus on that anymore; his hands drop down to her waist and fingers dig into her, pressing her body down harder with each pump of her hips into his, breaths now just shallow gasps for air.
