It doesn't take long--not like this, her knees at his rib cage and her fingers at her clit (and, uh. McNally with her hand between her legs--that's something he might actually have a kink for, so). Sam groans, works himself deeper, until--

"Sam," she gets out, around a gasp. "Sam, you gotta--Sam."

Sam laces their fingers together, shoves himself down one more time, and then--

(oh god, oh jesus--)

He keeps his eyes open when it happens, watches her come apart underneath him. He wants to see this happen, if he can.
