Work Text:
Jack and Nikki were bantering and roasting each other from their desks at work. Nikki came out with something really smart which had Jack raising both eyebrows briefly. She'd said, just to be cheeky, "Who knows? Maybe you won't always have a nervous effect on me when you make those facial expressions". He said, "Come over here and say that to my face. Without the "protection" of hiding behind your computer." Feeling bold, Nikki got up. She walked over to him slowly as he stood up. "I said, maybe you won't always- oh heck! No!" She gasped and quickly turned around. He'd made that face at her. Just as she'd turned around, Gabriel walked in. He saw Nikki looking flustered. "Are you okay?" She nodded. "Just Jack being Jack." Jack was smirking as he sat back down. Gabriel continued. "Can you go and see our victim's parents? They need some closure around the cause of death." Nikki nodded.
As soon as Gabriel left, Jack gave a deep chuckle. Nikki glanced up at him as she picked up her stuff. He did it again. She cleared her throat loudly and hurried out as he laughed. Discovering this facial expression had happened very randomly about 3 years prior. He was being cheeky with her one day when he just happened to do it. But with the way she'd reacted, blushing and unable to look at him to the point of turning her body away, they both realized it was a massive weakness of hers, much to his advantage. And he'd certainly used it to his advantage ever since.
After returning to the office a few hours later, Nikki had forgotten about what had happened a few hours beforehand. She and Jack packed up for the day and headed home. She sat on the chair whilst typing on her laptop, Jack sat opposite her, reading something. After a few minutes, she felt Jack's eyes watching her. She glanced up, and he did it again! She immediately glanced away, quickly saving the document and shutting her laptop when she saw him get up. When she saw him walk over to her, she leapt up and ran behind the table. She was unable to make eye contact with him. He was walking at a steady pace as she followed him with her eyes, walking away in the process. He spoke up. "I will catch you, you know." She smirked. "Good luck." She walked briskly towards the hall. He sped up his steps, prompting her to run back into the lounge. This time, as he walked towards her, he side stepped to block her opportunities to get around him. When she made an attempt to duck past him, he swiftly caught her by her upper arms and backed her into the wall. She was giggling as she attempted to push him away. He maneuvered her to the sofa, laying her on her back, preventing her from getting away. She looked up at him, an innocent look on her face. As soon as his facial expression changed, she looked away again. He decided to tease her. He sat on her waist, holding her wrists above her head with one hand and held her chin with the other hand.
He chuckled when she screwed her eyes shut. "You're trapped now. And I'm not letting go unless you look at me." She reluctantly open her eyes, only to see him with that same expression. She whimpered and shut her eyes again. She tried wriggling. He spoke deeply in her ear. "You're not going anywhere. Look at me Nikki." Unfortunately for her, his expression was the same and she shut her eyes again. He spoke with command. "Don't shut your eyes. I want to see you melt." She opened her eyes. Jack saw her heart racing on the side of her neck. She was whimpering within a few seconds. "If I release your wrists for a few seconds, do you promise not run off?" She shook her head. "No promises." She was smirking. He very quickly removed his shirt. She attempted to leap up, but he pushed her back down, holding her in the same position. When he said, "I'm not letting go this time", she gasped and whimpered when his facial expression returned.
This was torture, albeit pleasant. That facial expression, plus his defined and muscular form right in front of her, plus his overpowering strength, it made her body react within a minute. "Jack Jack Jack! I need to get up!" He knew exactly why, but shook his head. "No no no, you're staying there. Watching you like this is amazing!" Seeing her response to him, including the fact she was bright red and perspiring, was simply glorious. She reacted multiple times before she became exhausted.
He scooped her up and lay next to her. "I'm too tired to be intimate now. I'm sorry." He shook his head. "Don't be sorry darling. Why are you apologizing?" She said, "Because I feel guilty for not giving you anything back." He looked at her. "Nikki, I give you pleasure because I want to, not because I expect anything in return." She spoke. "But I haven't given you anything back." He looked confused. "You literally just did." "How??" "By simply reacting to me looking at you the way I did. And your reaction was pleasurable to me. Nikki, giving me pleasure doesn't always mean having sex. It's also seeing the way you respond to me." Nikki cuddled into him as he wrapped her in his arms. She kissed his chest. "I love you." He kissed her head. "I love you too." They had a quick shower, Jack washing Nikki was pleasurable for him. They ate then went to bed, asleep in each other's arms.
