Stiles didn’t know if the feelings he had, the feeling of completeness when Derek was so deep inside him, the warmth that settled over his body and whole soul- they could have been to do with that bond, or just the love he felt for him. But God, he felt so complete the moment Derek’s hips were flush against his bottom.
The praise was almost too much for him. He loved it when Derek spoke to him in such a way. He purred, hearing that sweet noise he’d only started making since they’d come together, “Always. All this for you. Want you to be proud. Want other alphas to know how much I want you-“
He cried out when Derek pulled back, the drag, the following emptiness- the slowness was incredible. They never went slow, but it had Stiles on edge, desperate, hungry for more friction. He’d tell Derek next time. Tell him next time they were in this position. Because now Derek was moving again, fucking him, knocking moans out of Stiles each time.
He hadn’t taken his pills yet. He hadn’t- this would be the third time they’d knotted within hours, he hadn’t taken his pill-
Derek had growled it into his ear and hadn’t stopped. He hadn’t stopped pounding into him. Stiles sobbed, twisting his fingers in the sheets, his erection leaking heavily. And Derek continued talking, talking about their child, about impregnating him now. That tomorrow, by tomorrow, he could be making their child.
He hadn’t taken his pill, that was irresponsible, but it was impossible to feel guilty about that now.
Stiles bowed forward, lifting his bottom higher, changing the angel. Derek’s thick head rubbed his prostate with every rough thrust, and he could feel the gradual swelling of his knot as Derek slammed into him.
“Can feel it-“ He panted. “I can feel it, Alpha. You’re stretching me open-“
Alpha. He didn’t call Derek that, only to tease. It came so naturally in the moment. He cried out, another sobbing sound as Derek finally caught, his knot finally too big to pull out.
“Yes, Yes, please- oh- oh god, Derek-“ Stiles whimpered before another orgasm rocked through him. Tears prickled in the corners of his eyes. “Don’t stop. Don’t . Give me everything.” His clenching muscles made Derek feel even bigger, his rim squeezing around his mates knot, holding it against his prostate and prolonging the pleasure.
