Ziva looked at Tony as her heart began to sink. The realisation that she had lost the bet, a challenge to Tony DiNozzo began to set in. He challenged her the day before on who could write up the most reports in one day. Normally she would have won. She always beat Tony at writing up case reports, but she knew this challenge he didn't want lose. They both agreed that the person, who lost, would be the slave for the other for a day. Doing whatever was asked. They even shook on it, and sealed with a kiss. She thought that she had the challenge in her hands, beating him easily at something she normally did well at but this time he had a motive to get going. As mcgee noted how many cases everyone had done at the end of the day, both he and Ziva came to shock to see Tony had done more than anyone. Tony looked to Ziva as they walked together to the elevator. He leant over whispering into her ear.

"Looks like your apartment tonight David"

Tony smirked at the pride of winning the challenge, and he knew exactly what he was going to put her through.

"Oh and Zi, I've got tomorrow already planned ready for you"

Tony smirked and leant back towards Ziva's ear. He quietly moaned her name causing her to fight her inner strength of control. Ziva moved on the spot trying not to give any hint away at what she was expecting him to do. Most likely pretend they were dating for the day in front of the team. Ziva chuckled.

"Oh don't worry DiNozzo. Nothing you can do will surprise me"

Ziva smiled thinking she would manage being his slave tomorrow. It's not like he could do too much. Though she did have a gut feeling he was really up to something. Ziva looked at Tony who was grinning, her cheeks slightly blushed. Instantly she shot to looking at the elevator door.

At Ziva's apartment

##### ##### ##### ##### ##### #####

Ziva slammed her door shut, looking around to see if any neighbours were being nosey. Luckily no-one was around when Tony followed her into her apartment. His face was filled with a smut smile. She walked over to her fridge knowing it would be mainly empty. She looked to Tony.

"Take away?"

Tony walked up to Ziva.

"Sure thing sweet cheeks"

Ziva turned to Tony, she grabbed his wrists spinning him around and shoved him against the wall.

"Don't you ever. I mean it Tony, don't you ever call me that name"

She looked to Tony frowning as he burst out laughing. She secretly loved it when he called her that name, she wanted to pull him into an embrace and kiss him but she couldn't let him know that.

"Ziva" Tony chuckled. "You lost the bet to me remember. You're mine until 8pm tomorrow night"

Tony leant forwards and kissed her lips. He smirked and leant back watching her face go still. Her cheeks looked like they were about to set alight from where she was blushing. Ziva looked at Tony in the eye. He just did something she wouldn't expect. She knew he's been crushing on her for a long time. He even proved his love for her when he came to rescue her from Somalia. He had risked his life for her. Ziva looked him deep in the eyes; she could tell he was trying to control himself.

"To-"

Tony brought his hand out of her grip and his finger to her lips. He smiled and pulled her close, pushing his groin against her. He was already raging hard. He wanted to get straight in her pants but knew he couldn't. He smiled whilst she was distracted he grabbed her and spun them around so he had the advantage of her against the wall. Ziva's eyes shot open as he leant forwards kissing her lips softly, both closed their eyes and let their tongues wrap around one another. Ziva moaned quietly as Tony's hand went up her shirt, wrapping his fingers around her left nipple. Squeezing them he kept their kiss going until Ziva pulled back for air. He smiled as she growled low in her voice. He knew she was starting to get wet as his hand worked her nipple. Slowly he removed her hand to Ziva whimpering. He smiled, he had the upper hand. He picked Ziva up, resting her on his groin with both legs around his waist. He smirked then thrusted against her trousers knowing he was causing friction in between her thighs. Ziva let out a slight whimpering moan as Tony's raging dick rubbed against her clothes in the right spot. She knew her body was raging for him to go further, she wanted him to go further. He carried her slowly through to her bedroom. Though it wasn't very feminine it suited Ziva a lot. Tony fell forwards against Ziva's bed causing his raging hard dick to press hard against her clit and knocked it as they bumped on her bed from landing. Ziva moaned at the same time as Tony. He smiled as he sat up slightly above her. Tony kissed Ziva's lips tightly as he moved his hand down and began to rub her thigh. Ziva moaned as Tony's hand ran up her trousers and rubbed slightly above her pant line. He knew she wanted his hand further. Tony lifted up a bit and began to slide Ziva's top off with her will. He smiled as she took off her own bra for him.

"To-"

"No Ziva. Quiet"

He smiled as he began to kiss down her neck until he reached her right nipple. He wrapped his mouth around it with his teeth nibbling on the nipple softly. He smirked as he pulled her trousers off, along with her blue thongs. He looked up to Ziva whimpering. She was looking down. He smiled then pushed her up the bed into a sitting position. Ziva looked at Tony confused, he had sat her up. But why? He smiled and opened her legs softly. He kissed her lips then kissed lower and lower until he reached her pant line, he then began to kiss down the inside of her left thigh, up again then the same with her right. Moans slowly escaped Ziva's mouth. She looked down to see Tony diving in between her legs and felt something brush along her clit causing her to buck. Tony smirked as he looked up to Ziva who was looking at what he was doing wide eyed. He knew it added more to the pleasure making her watch what he was doing to him. Ziva moaned as Tony's tongue rubbed across his clit then began to suck on it. She groaned as she arched her back and put her head back but Tony pushed against her stomach from stopping her from arching too much. He smiled as he used one hand to force her head forwards forcing her to watch. She felt her body shudder as it was getting close to climax. She moaned as Tony's tongue slowly entered her dripping pussy. The feeling was intense and sending her wild but she couldn't buck or look away. It was entrancing watching Tony's head work her like that.

"Oh god Tony!"

Ziva screamed his name as she was forced forwards from the orgasm shuddering through her. Ziva moaned louder as she began to cum in Tony's mouth. Even though she was cumming he continued to keep licking, but lifted his hand towards her stomach and began to work her clit. Instantly Ziva moaned as she was forced into a second. This time Tony stopped and looked at her. He smirked as her face was flustered, full of pleasure. Ziva's mouth was wide open, panting and breathless. He smirked and knew this was the opportunity to get her whilst recovering. Before Ziva could react she closed her eyes and leant her head back trying to get her breath. When she felt something warm… solid against her thigh she leant forwards eyes open to see Tony had stripped and had his raging hard dick against her wet slit. She tried to move but before she could Tony thrusted slowly into her. Painfully slow. Millimetres by millimetres. He smiled as he knew it was painfully teasing him as it was for her. He smirked then was surprised when Ziva bucked forwards throwing herself quickly onto his dick. Shoving it all in her at once both groaned at the pleasure. Both Ziva and Tony began bucking against one another. Feeling their bodies driving out of control, causing them both to buck, moan and cum at one another.

Next Morning

##### ##### ##### ##### ##### #####

"Tony I am not having that!"

Tony smirked. He had Ziva on her back, legs up over his shoulders and her hands trying to push her up.

"Oh yes you are Ziva. You agreed, mine for the day"

He smirked as he pushed a remote control vibrator and Ben Wa Balls into her pussy. Though it was slightly dry he knew it wouldn't last long. Tony smirked as Ziva bit her lip and arched her back.

"You're too keep them in at work, no removing them or hinting at people you have them in"

Tony smirked. He had the remote control to the vibrator, and attached a bit of string to the Ben Wa Balls ready to attach to her belt so he can have a lil tug when he wanted. Tony smirked. Today was going to be fun. He pressed level one on the remote control and tugged the string a little.

"TONNYYYYY"

Ziva's voice rang in his ears. Pleasure and horror. Ziva couldn't believe what Tony was doing, he had gobsmacked her and now was going to tease and torture her throughout the day. It was bad enough last month when he teased her to the point she had to finish herself off in the toilet and almost got caught. Now she was at his mercy.
