Athrun closes his eyes and breathes. He presses his forehead into the crook of her neck and feels rather than hears the sharp intake of breath when he presses a thumb to her swollen clit. Her legs spasm around his hips as he pumps her faster, and he presses a wet kiss to her warm skin.
The sounds she makes are glorious. "Ath—" she begins before the sound is caught in her throat at a particularly forceful thrust of his fingers. Clawing at his back, roughly enough to leave scars the next day, Cagalli throws her head back, arching into him and pressing her full breasts against his chest. She bits her lip and tries not to beg.
"Let me hear you," he says against her skin, licking his way up the column of her throat.
"N-no," she answers defiantly, but it's useless. His skilled fingers have her writhing underneath him, mewling and whimpering at his touch.
He learns close to her ear and whispers, "Come, Cagalli. Come for me. Let me hear you roar."
Not a moment later and she shudders her release, pawing at the raw skin of his back and howling his name. Smiling, Athrun hums with satisfaction as he pulls his hand out from between her legs and brings his fingers up for a taste. Cagalli, chest heaving as she tries to catch her breath, glares at him in vexation. It would have been much more effective, he thinks, if she weren't red-faced and naked beneath him.
"That's a good lioness," he says gleefully.
"Fuck you."
"Oh, I will, don't worry," he speaks before stealing a kiss.
