His mate didn't have to beg for Derek to keep him full, but Derek loved hearing it, loved knowing that he and their kids were wanted so badly by Stiles that he'd do that.
And even under his roar, he could hear that cry, feel the shudder that ran though his mate when he came, the burst of salty-sweet that meant Stiles came. But his mate wasn't stopping -- his beautiful, fabatasic mate that wanted their kids as much as he did -- was still rolling his hips up, teasing at his knot and Derek growled against his shoulder. Stiles still needed -- his mouth opened, teeth setting against his shoulder as he shoved in, knot throbbing as more of his come pulsed out to fill him.
There were tears, but nothing in his scent, only the spicy sweet of arousal and pleasure. "Okay?" He asked even as he rocked in hard enough to nearly push Stiles flat against the bed with a littl rumble.
Whatever was going on between them, the need that he couldn't shake to stay buried deep and keep Stiles full of his knot, or the one to provide whatever he needed -- Derek wasn't in a place to resist. He wanted it, wanted Stiles full, pregnant, provided for, happy. His free arm came up to wrap around his chest, keep them flush as his hips edged forward, rutting his knot into the slight swell of Stiles' prostate.
"Love you. Mine. Mine. My mate. My Stiles. My Mieczyslaw," He crooned in return, the words sloppy around his still enlarged teeth. He nursed his nose against the healing bite mark on his throat, and breathed out noisily, shuddering as the muscles gripping him worked another pulse of come out.
