As soon as he could think, Stiles words caught up to him and he grinned down at his mate, his hips still slowly moving, nudging his cock up against his prostate.
"You think you need to eat me out to get all worked up for you?" His hands drifted down from his shoulders, palms and fingers sliding through the mess he left on Stiles' skin and starting to slowly rub it in. Stiles might not have a mark yet, but Derek could damn sure make it so he reeked of alpha.
"You don't," he slurred out as he did a slow screw downwards onto his mate. "As much as I love your tongue, and as much as I'd love to have you fuck me with it," he leaned down to kiss his mate, slow and filthy, because it seemed like a damn shame not to show some appreciation to Stiles' tongue while they were talking about it.
It didn't stop him from doing those lazy little circles with his hips, and as soon as their kiss broke, he was grinning again. "All I need to want you is to have you close. Put you in my bed and I'm going to want to knot you." His hands skimmed along his side, following the narrow taper of muscles, thumbs brushing through the trail of hair south of his navel.
His muscles clamped down tight at the brush of the plug, his thoughts mirroring Stiles'. "You sure you don't want to put in me like this? Cause," he moaned as he straightened up. "If it was your knot, I'd keep riding you, see if I could get it just right and come again, and again, and again, like I'm going to do to you tonight. Fuck you slow with my knot, see how many times I can make you come while I get you pregnant."
His eyes were still glowing red as he teased himself up and down Stiles' length, waiting to hear what his mate wanted, because he was sure he could keep going and in another few minutes, come all over him again. It was already good enough that his toes kept curling up, and his cock, still hard and slightly swollen at the base, kept bobbing up towards his belly.
And then, as if to tempt his mate, he ground down slowly, that beautiful, wonderful cock stroking right up against his prostate and forcing out another splash of come as he moaned. "Fuck... Think how much come you'd keep in me if you came a second time."
