The increasing pace has Sweeney feeling like he's stumbling forward, even while laying on his back. He's constantly trying to catch up as every muscle in her is pulling him along. There's no way to quiet the moans or winces as she claims him, but he does manage to shift his hands a little.

One slides a bit further back, as the other drifts forward, allowing him to feel like she's still steady on him (not that that was ever an actual risk) while urging his thumb over her clit. The pressure isn't cruel, but it's firm. He doesn't stroke her actively; Sweeney just makes sure it bounces in echo with each stroke she steals.
