Wolve's Mate

For: Arashi Wolf Princess (her birthday is today (Aug. 30))

Derek stared at Stiles not speaking. STiles laid on his bed, froze in shock.

"You could have waited." Derek said.

Stiles's face slowly became red. Derek moved over to him and pulled his hand away from his ass. Stiles moaned in loss and embarrassment. Derek smirked lightly as Stiles squeaked when he rubbed two of his fingers against Stiles's hole.

"Tell me what you want." Derek said, applying a small amount of pressure.

Stiles pushed against him; Derek moved back, repeating what he had said. Stiles whined, wiggling his ass in front of Derek.

"Finger me." Stiles whimpered.

Derek moved back toward Stiles, circling his middle finger around his hole before pushing it in. Stiles moaned and arched his back.

"You're always so tight." Derek muttered, adding another finger.

Stiles gripped the sheets under him. Derek's fingers were bigger than his, stretching him more. He groaned as Derek added a third finger. He pushed against Derek's fingers, moaning as the pushed against his sweetspot.

"N-no more, I want your dick now." Stiles whimpered, grabbing Derek's hand.

Derek took a step back and removed his shirt. Stiles was at his jeans quickly, removing them and the boxers. He sucked slowly as Derek fingered him.

Stiles pulled back with a pop. He kissed the tip before laying on his back and spreading his legs.

Derek moved between them. "You're like a cat in heat."

Stiles slightly blushed. "I can't help that I like your cock in me."

Derek smirked and pushed in with one swift thrust. Stiles arched off the bed. His arms wrapped around Derek's neck and moved to sit in his lap.

Stiles bounced in Derek's lap, panting and moaning as Derek held his hips and helped him move. This was one of their favorite ways to be close.

Derek's hands ran up and down Stiles's body, enjoying the soft feel of Stiles's skin. He could tell be the was Stiles was moving, he was close.

Derek wrapped his hand around Stiles's cock. "Come Stiles, all over my hand."

Stiles shivered as he came, arching his back and clenching around Derek's cock. Derek groaned Stiles's name as he came inside Stiles, his claws coming out and clawing at Stiles's body.

Stiles yelped as something swelled inside him. Derek pulled Stiles close to him, rubbing his thumb back and forth in Stiles's hair.

"W-what is this?" Stiles whispered, shifting uncomtable.

"It's a knot." Derek answered.

"Why's it happening?"

"My wolve's choice for a mate is you."

Stiles moaned softly in happiness, joy filling his chest even with the pain of his ass. Derek nuzzled his neck and kissed it.

"I love you." Stiles said.

"I love you too, Stiles." Derek said, leaning against the pillows behind him and bringing Stiles with him.

Stiles snuggled against Derek's chest as Derek wrapped the covers around them.
