PART TWNETY ONE

Stiles lay next to a sleeping Derek, again, and unable to sleep. He slowly got out of bed, and went to the bathroom. He flipped on the light and carefully padded in front of the mirror. He stared at his face in the mirror, dark brown eyes, and purple under them indicating his inability to sleep well. He placed his cold fingers under his eyes, trying to get rid of the purple swelling to no avail. He leaned away from the mirror, examining his naked torso in the mirror. He could see the scars of his love affair with Derek written all over his skin. He could see the bruises on his ribs from repeated beatings by the blonde whore. He saw the healed scars of finger nails in his hip, and the scars of the bite marks on his shoulder. He reached up and brushed the bite with his fingertips and looked away from the mirror. He was taking deep breaths, and braced his body on the edges of the sink.

Stiles closed his eyes and focused on the sounds of the house and searched for the sound of Derek's heartbeat. He found it, and let out the breath he was holding. His head snapped up when he caught the sound of the second heartbeat.

He shut the light off in the bathroom and walked into the hall, closer to the stairs and the sound of the heart. His bare feet made no noise on the wood floor, his steps crossing in front of one another swiftly and quietly. He picked up the scent of a perfume that was strangely familiar and he felt like a live wire, ready to pounce on the predator.

"You are stalking the wrong prey asshole." He whispered to himself, talking himself into the glowing green eyed beast he had been recently. He leapt around the corner, tackling the person down the stairs landing on top, pinning them to the ground. He realized that the person beneath him was a woman, but it was not Kate. She fought against him, trying to get her hands free, thrashing beneath him, creating friction which was strangely arousing.

"Get off me Stiles!" The shrill voice screamed the words as an order to him and he knew who he had trapped beneath him. The small girl beneath him was the red haired beauty, Lydia.

"What the fuck is wrong with you! You sneak into this house in the middle of the night and what? Scare the shit…what the hell?" Stiles shouted at her, not even trying to keep his voice down. He knew he was going to wake Derek and didn't care. He wanted Derek to come down and deal with this.

"You weren't in school!" She shouted at him. Her hair was in her face as she shouted at him through red lips. She was straining to get closer to his face, to taste him.

"Derek!" Stiles shouted over his shoulder, sensing when the older teen stepped to the top of the stairs and crossed his arms, taking each step hard and rough until he reached the bottom where Stiles still had Lydia pinned.

"Aww, no Stiles, throw this one back, it's poisonous." Derek sarcastically motioned at the girl.

Stiles laughed at the remark, and looked down at the now pouting teenage girl.

"It's not nice to taunt your prey you know." Lydia smart assed back at Derek, trying to seem tough despite her compromising position on the floor. Derek crouched down next to the teenagers. He stared at Lydia and then back at Stiles, whose eyes were still glowing green. Derek could see every muscle in Stiles was tense, the older teen admiring the chiseled body of the younger. Derek reached his hand out, caressing Stiles' shoulder and running his hand down Stiles' ribs, feeling the muscles in Stiles abdomen tense under his touch, watching the smaller teen shiver under his caress. He leaned over and planted a gentle kiss on Stiles' neck, making Stiles close his eyes and moan softly.

Stiles leaned his head to the side allowing Derek better access to his pulse point. He felt himself getting hard. He heard a cough and opened his eyes, suddenly blushing in the darkness as he realized Lydia was still beneath him. She was awestruck at what she was watching.

Derek stepped behind Stiles, snaking a hand around Stiles bare stomach, tucking his fingers into the waistband of Stiles' boxers. Derek locked eyes with Lydia, challenging her to protest at the intimate touching between the boys. Derek leaned down and placed his lips on Stiles' shoulder, on the scar of the last bite. He kept his gaze locked with Lydia, mesmerizing her.

Stiles released one of her wrists and leaned back into Derek's kiss. Derek sank down onto his knees, straddling Lydia's legs. Stiles reached back and pulled Derek's lips into his neck harder, moaning at the intimacy and need he felt in Derek's tightening grip on his stomach.

"Derek don't tease." Stiles moaned, unable to contain his lust. Lydia watched, still pinned beneath the boys, she reached a hand up and slid it from Stiles' knee slowly into his inner thigh, inching her fingers up slowly to Stiles' erection. She slid her hand up Stiles' boxers and rubbed the tender skin of his inner thigh. Stiles turned his head as Derek leaned in and claimed his lips, proving to Lydia that Stiles was his.

"You came here for him didn't you?" Derek asked her quietly, Stiles turning his torso just enough to be able to suck the pulse point in Derek's neck. Derek closed his eyes, he loved it when Stiles was eager.

"Mmm, let her watch, let he be jealous of what she is missing, let her join and feel the absolute pleasure of your cock, knowing she will never feel it. Ever. Again. Because you are mine Derek." Stiles was turning Derek on, wanting to prove that he was Derek's and that Derek was his.

"Is that why you came here? For the both of us?" Derek smirked, not sure if he wanted to share Stiles. Lydia bit a swollen lip, feeling the blood in her body rushing to her lips and groin. She pushed her hips up and into Stiles' body still straddling her.

"Yes." Lydia's response was short, heavy breath.

"Beg me to share him, prove to me you are worth it." Derek said to her harshly, turning his attention back to Stiles and dipping his hand into Stiles' boxers stroking Stiles' cock softly, and slowly. The younger teen moaned loudly into Derek's mouth, sliding his hands back to dig his nails into Derek's boxer clad ass.
