Stiles grinned as Derek nuzzled hungrily against him. That he was giving off a scent that his mate found so addicting pleased Stiles no end. He liked that he was a good mate. He was a good mate for Derek. He did everything a good omega should do.
“Hm,” Stiles purred happily at the thought of everyone knowing. That Derek’s pack would know he’d picked his mate and claimed him. The bite on his neck would be enough, but he wanted them to know Derek was enjoying his body, too. That Stiles was arousing and fertile and would be so good for the pack.
He didn’t resist as Derek moved them, knowing it wouldn’t be a good idea to move against the motion of his mate. He knew he was safe with Derek wrapped around him, he knew nothing could hurt him. Not only because they were alone, but his mate would keep him safe.
And God, he really hoped that Derek would be able to smell if he was pregnant. He hoped that his scent changed to tell Derek something had happened. The thought warmed him, and then Derek was wriggling against and Stiles moaned.
“Yes,” he sighed in agreement. “Give me everything-“
The brush over his nipples made Stiles gasp, muscles fluttering around Derek’s knot. He could come again. He wanted Derek to come again.
“Here, touch me here-“ Stiles whispered, guiding Derek’s hands to his chest, to both nipples and the (maybe slightly softening) area around them. He moved Derek’s fingers, making him grope, showing him just what he wanted. It was rough but sensual. At the same time he rolled his hips, pushing down against Derek’s cock, rubbing himself against his knot. Derek was right, with the distraction it wasn’t too much. No, it was good. Very good.
Stiles moaned happily. “You like this?” He asked, tipping his head to allow Derek more room to breathe in his scent. “You like me using you for my pleasure? Riding your knot, making you come, using you to get pregnant.” That wasn’t true, of course, they both wanted it, but Stiles wasn’t going to have a baby with anyone else. “Gonna make you come inside me again. Gonna make sure I have your child inside me-“
He bit down on his lip, then let out the cry he saw no reason to hold back. His hips moved faster, riding the thick knot inside him.
“Yes, Yes, Derek, right there. Right there, baby. Fuck- fuck, so good. I’m so close, so close- oh god.”
