As soon as Sam pushed that finger inside of him, something hitched up tight inside Sasuke's chest released, and a low, long moan spilled out, pitch shifting just a little as Sasuke's head fell slowly back. His hips rolled back, pushing back onto the intruding finger, wordlessly begging for more of this touch. The crooks and wriggles of the other's finger inside him earned a series of quick twitches, low grunts. And when the second pushed inside, the moan that it incited was loud, higher-pitched, shuddering out as both hands shifted again to dig nails at the wall.

The touch of teeth again, coupled with this deep, searching touch, had dark eyes rolling back under half-fluttering eyelids. A soft, too-high little note like an aborted keening noise found its way out between gritted teeth when Sam spoke. "Please..." he heard himself say it only distantly, and immediately clenched his teeth hard shut again. Fuck.
