Jealousy

The sun was shining in through the window, too bright to be deterred by the curtain covering it. Dean stared down into his lover's eyes. This wasn't the first time he'd lured Buffy Summers into his bedroom, but this time was going to be different.

If she said yes.

Right now she wasn't saying much of anything, other than "Oh god."

The door opened slowly, and Sam walked in, looking uncertain. Dean turned his head to look over his shoulder, then nodded to his brother. He slid a hand under Buffy's back and rolled with her so they were laying on their sides, her left thigh pinned under his waist, then continued rocking against her.

Sam laid down behind Buffy and ran his fingers down her back.

She shivered in surprise and her eyes flew open. "What-"

Dean kissed her mouth quickly. "Shh." He told her. "Say no if you want." His gaze lifted to his brother's eyes, then looked back into Buffy's. "But Sam wanted..." He laughed nervously. "We both wanted."

Her eyes widened. She turned her head to look up at Sam.

"Please?" Sam asked quietly.

She surprised herself when she nodded in agreement.

Dean exhaled in relief and pulled her hips more tightly against him, groaning as he slid deeper within her. He turned her head toward him and kissed her.

Sam kissed Buffy's shoulder as he eased into her slowly. Despite his caution, she nearly shrieked.

"Jesus christ, Sam!" Buffy panted. "That's...you didn't ask me for that!"

"Where else was I supposed to..." Sam mumbled, embarrassed.

Dean gave them both amused looks as he pulled the upper half of his body slightly away from Buffy's and brought a hand up to fondle her breast. "You girls are so cute." He smirked.

"Fuck you, Dean." Sam snapped.

"Aww, Sammy. Aren't you busy right now?"

Buffy barely noticed that they were talking. Her body felt like it had electrical currents flowing through it. She closed her eyes and bit down on her lower lip as she started moving against both Winchesters.

Sam looked startled for a second, then picked up Buffy's rhythm and began thrusting.

"Mmm. Yeah." Dean moved his hand out of the way and pressed his chest against hers again, grasping her thigh and pulling it up toward his ribcage.

Buffy's breath caught in her throat, and then she was babbling incoherently as she kissed everywhere within reach on Dean's face, then looked into his eyes even while she was speaking to his brother. "Sam."

"Hmm?" Sam murmured.

"Sam." She said again, and wiggled impatiently as she turned her head toward him as best she could, given the way she was positioned.

"Oh." Sam lifted the upper half of his body and twisted his torso while he leaned down toward her. He kissed her gently, then nearly growled when her tongue slipped into his mouth.

Dean felt his stomach muscles tense up, like he was ready to attack someone as he watched his brother and his lover practically panting into each others' mouths. She was his, and this idea had been stupid. He moved toward the edge of the bed, pulling her hips to keep her with him, then rolled her onto her back and loomed over her.

Buffy looked up at him, a confused expression on her face.

"Get out, Sam." Dean snapped, not looking at his brother as he put both of his hands on the bed, above Buffy's shoulders. This had turned into something he didn't want at all. When he heard the door click shut, he leaned down to whisper in the ear of his slayer. "You're mine. You know that, don't you?"

Her mouth suddenly dry, Buffy's voice sounded funny to her when she spoke. "Uh huh."

"You ever let my brother near your lips again, I'll remind you who you belong to." He said darkly, starting to thrust within her again. "Me. Only me."

"I thought you wanted..that." Buffy gasped.

He licked his lips and gently tugged on her earlobe with his teeth. "Doesn't matter what you thought." He rested his weight on his legs as his hands slid under her hips and pulled them up from the bed. "Mine." He looked down at her with a smirk on his face. "I can feel you getting close. You gonna come for me?"

"Yes." Buffy blurted, not sure what had happened to her boyfriend, but she wasn't about to complain. She liked seeing him this way.

Dean slowed his pace, then. He needed control.

Buffy whimpered and thrust her hips against his. "Dean." She pleaded.

"That's the name that should've been coming out of your mouth a few minutes ago." He glowered.

"I'm sorry, Dean. Please."

"Tell me you're never going to do it again." He prompted.

"Never."

He started driving into her, hard and deep. "Turned you on." He breathed. "All that talk of you being mine. You love it."

"Love you." Buffy blurted, her eyelids growing heavy with need. They shot open a second later and she nearly screamed at the feel of release. "God, yes."

As her last wave hit, Dean's movements were frantic. "I'm gonna...." But that was as far as he got before his body shook with his own orgasm. He laid on top of her while he caught his breath, then pulled out and moved to her side, laying on his back.

Buffy closed her eyes, basking in the afterglow, until Dean spoke again.

"Love you too."
