Those quiet little pleas -- Derek knew what they meant (all of the above) and he tired, he tried so hard to give his mate just what he was craving.
In these moments, he didn't care that Stiles was on contraception, that he was too, that they were actively trying not to get pregnant. Every bit of him said that it was good and right to fill him with children, that it was something they both needed.
And his wonderful mate -- always so ready for it, letting out those little sounds, that cry as he arched up against him like an offering to take, and Derek couldn't resist.
Knowing how much his mate loved his claws and fangs, he rubbed the former up his sides, scratching without breaking the skin, a constant reminder of their length and sharpness. The former he dragged across his throat, hips still working steadily against him, knot still rocking slow inside.
He felt there first, in the squeezing of his muscles as he tried to clamp down around his knot and couldn't quite make it. Derek growled out his approval, not bothering to hold the sound back, not when Stiles enjoyed it so much. He held his mate through the tremble, the fresh burst of scent forcing him to rut deeper. Just a little bit -- his hands clutched at Stiles' waist, holding him still as he bucked in and came again.
He kept rocking through the aftershocks, making soft little pleased noises against Stiles throat.
His mate was so good, so good -- his arms slid under Stiles' body to wrap around him, and he pressed his face deep into the corner of his neck where it met his shoulder. "Mine," he rumbled happily, the tip of his ear flicking slightly as he listened to -- geez, Isaac.
Maybe if he tried a little harder he might be able to pick out the scents of his betas and what they were up to under Stiles', but he didn't want to. He wanted Stiles' scent for a little while longer, even as his fangs began to recede, and his more wolfy features faded back into his human ones.
"One more," he heard Erica say to Boyd from where she was bouncing on his lap, sounded like.
Mmm, one more he could do. He pressed a wicked grin into Stiles' skin and arched his spine, the tip of his tongue dragging down his chest to one pointed nipple.
