Just about everyone at SVU had gone home for the day... everyone except Elliot and Olivia. They were in the gym working out together. They always worked out together. They enjoyed competing against one another on the bikes and treadmills. Olivia would spot for Elliot on the free weights and in return Elliot would help Olivia stretch. Olivia was getting very flexible and Elliot was beginning to have trouble controlling his body's reaction as his hands moved over his partner's perfect body.

That night, after they finished working out, Olivia headed into the women's locker room leaving Elliot to turn the lights out. She was straddling the bench in the middle of the room, with her back to the door, drinking water and letting her heart rate return to normal. She was breathing so heavily that she didn't hear Elliot sneak in. She was always fully aware of what was happening around her, but she let her guard down while she was in the police gym with her partner. Just as Olivia was getting ready to take another drink of water she felt two strong arms around her waist and her body was suddenly pressed up against someone else's body. Instinctively she grabbed at the arms around her waist and began to struggle but she was unable to break free.

"Liv," Elliot whispered as he gently kissed the side of her neck, just behind her ear.

"El?" Olivia asked, completely surprised. She stopped struggling. "What are you doing?"

"Liv, I want you," Elliot replied softly as he slipped a hand under her tight workout shirt and rested it on her stomach.

His hot breath on the back of her neck and the skin to skin contact made Olivia gasp as she tried to catch her breath. Olivia often looked lustfully at her partner, especially when they were working out and his top half was bare. Even though he had recently divorced Kathy she never thought their relationship would make it to this level. After all, there were rules against that. She wasn't sure what to think of what was happening but her thoughts were interrupted as Elliot pulled her shirt up slightly, revealing her tight, firm stomach, and then pulled her body even closer to his, his arms still firmly around her waist.

"Elliot," Olivia started to protest, until she felt his lips moving across the back of her neck. She let out a soft moan as she bowed her head forward revealing more of her neck to him. She started to feel moisture between her legs.

"Mhmm," Elliot hummed, as if to ask what, his eyes studying the back of her neck.

"El," Olivia was almost completely under Elliot's control at this point. She decided against trying to walk away from what she knew was going to happen. "El, I'm gross... stinky and sweaty from working out."

"Mhmm," Elliot moaned again, not wanting too many words to take away from the moment. He felt Olivia start to relax in his arms which was his sign to keep going. He let go of her waist as he grabbed the bottom of her shirt and gently pulled it up over her head. He studied his partners back, running his hands from the top of her pants, softly up her body until he reached her bra. He released her bra and then began rubbing her shoulders and massaging her back, placing kisses down her neck and back every so often.

Olivia arched her back as she let out a moan of pleasure. She put her hands on the inside of Elliot's knees, slowly running them up his thighs and under his workout shorts. They met in the middle as she grabbed his hardening cock through his briefs. Elliot let out a deep moan as he jerked his hips up and forward into Olivia's hands.

Elliot's hands made their way down Olivia's back, over the top of her thighs, stopping in between her legs. He could feel her squirm as he rubbed her, through her shorts, starting with the tips of his fingers and moving his open hand gently down her middle until he stopped with the palm of his hand and pulled it back up again. Olivia shrieked with pleasure and laid her head back on her partner's shoulder. Elliot kissed her cheek and used his free hand to pull her chin towards his, letting their lips meet.

"Liv," Elliot said between kisses. He tugged on the waistband of her shorts.

Olivia stood up, not even making him finish his sentence she removed her shorts as she turned around to face Elliot before sitting back down. She put her hands on his shoulders as her eyes feasted on his toned chest and abs. She moved her hands down his chest and across his stomach, taking her time. She found his cock and began rubbing it through his shorts, cupping it and squeezing it. She wanted it out. As if reading her mind Elliot stood up and quickly removed his shorts and briefs, Olivia's eyes dancing around his body the entire time. She reached out and grabbed his stiff cock and before he could sit back down she took it in her mouth.

Elliot, completely shocked by this let out a long, deep grunt. He took a step closer to Olivia as his hands found her cheeks and moved down her neck, finally resting on her breasts. He gently squeezed them, then massaged each, already hardened nipple. Olivia was taking her time on his dick. When she pulled it out of her mouth and began swirling her tongue around the head it was almost too much for Elliot. He backed away, not wanting to cum all over her face.

"Come here," he said, grabbing her hand and leading her to the couch in the powder room part of the ladies locker room. I finally figured out why women have these cozy powder rooms all decked out to look like someone's living room, Elliot thought as her chuckled to himself. He laid Olivia down on the couch, taking in her naked body before he climbed on top of her.

Olivia was already moving her hips towards him grinding against him, before he could line his cock up with her entrance. She was more than ready and she wanted it bad. "Whoa, slow down," she heard him whisper as she reached her hands between their pressed together bodies. She lined him up with her and started thrusting towards him.

Elliot was dangerously close to the edge, he started teasing his best friend. He held her hips down as he entered her part way and pulled out again. He leaned into her, their lips meeting again. God, he is such a good kisser, Olivia thought. He came at her with his mouth open; he started pulling on her bottom lip with his lips. She opened her mouth and let him in. His tongue took over her mouth as his lips massaged hers. He pushed his cock all the way into her. She let out a long, deep sigh into Elliot's mouth. Elliot's eyes rolled back into his head in immense pleasure. Elliot knew it wasn't going to be long for him, he didn't think it would take long for Olivia either. He reached his hands around under her, grabbing her butt. He stopped thrusting while he moved her body up and down and side to side against him.

Olivia started moaning and thrusting as Elliot still had control of her hips. Elliot knew she was close as he felt her body tremble beneath him. He started thrusting into her again and soon felt her contracting around him as he heard her moans and screams. With a few final direct thrusts Elliot joined Olivia in climax before collapsing on top of her.

"Wooow!" was all Elliot could say as he tried to catch his breath. He heard Olivia's low moans as she was still breathing heavy. He started to climb off of her to let her breath easier.

"Where are you going?" she asked, wrapping her legs around his backside, pinning him there. "Stay in me, please, just a little longer."

Elliot raised his eyebrow, looking at Olivia. He broke his smile as he went in for another long, passionate kiss.
