Chapter 3
The rest of the morning felt like a slow torture for Diana, because every time she looked up from her plate, she found Keith watching her with that same heavy, knowing expression. Leo was still rambling on about his job and some drama with his coworkers, completely oblivious to the fact that his best friend was basically stripping his sister naked with his eyes right across the table. Diana tried to focus on her food, but she couldn't taste a thing, and all she could think about was the way Keith had pressed himself against her in the kitchen and the way his voice had dropped when he told her he wins every game he plays. She felt a constant, pulsing heat between her thighs that made it hard to sit still, and she found herself shifting in her seat, rubbing her legs together just to get some kind of relief.
Keith didn't make it easy for her, because he kept finding ways to bring the conversation back to things that felt like secret codes between them. He would mention how the house felt quiet or how he liked the way the morning light hit the room, but he always looked at her when he said it, making sure she knew he wasn't talking about the architecture or the weather. He was marking his territory without saying a word, and Diana felt herself sinking deeper into the role of the prey, though she was the one who had invited the predator in. She loved the danger of it, the risk of Leo finding out, and the way Keith seemed to enjoy the thrill of doing something forbidden right under her brother's nose.
"I think I'm going to head out to the garage and finish working on that engine," Leo said, finally standing up and stretching his arms over his head. "You want to come help me, Keith? I could use a hand with the heavy lifting on the transmission."
Keith leaned back in his chair, his eyes never leaving Diana's face, and he let out a slow, lazy smile that made her stomach flip. "Yeah, give me a few minutes, Leo. I just need to finish my coffee and maybe help Diana with something first."
Leo didn't even think twice about it, just nodding and heading toward the back door. "Alright, don't take too long, man, I want to get this thing running by the afternoon," he called out over his shoulder before disappearing into the garage.
The second the door clicked shut, the atmosphere in the room shifted instantly, and the playful tension from the kitchen turned into something much more aggressive. Keith didn't move for a moment, just staring at her, and then he stood up and walked around the table with a slow, predatory grace. Diana stayed in her chair, her heart hammering against her ribs, and she watched him approach, feeling the air grow thick with the scent of his cologne and the raw energy he radiated. He stopped right behind her, and she felt his hands land on her shoulders, his grip firm and possessive as he squeezed the muscles there.
"Now that the big brother is gone," Keith whispered, leaning down so his lips were brushing against the shell of her ear, "we can stop pretending for a little while, don't you think?"
Diana let out a shaky breath and tilted her head to the side, giving him better access to her neck. "I thought you wanted to see how long I could keep the act up," she murmured, her voice trembling. "Are you getting bored already, Keith?"
He chuckled, a low vibration that she could feel through her shoulders, and he slid his hands down from her shoulders to her chest, his palms grazing the fabric of her sundress. He didn't stop until his hands were cupping her breasts, squeezing them firmly through the thin material. Diana gasped, her back arching instinctively, and she felt her nipples harden instantly under his touch. He knew exactly what he was doing, and he enjoyed the way she reacted to him, the way she was completely at his mercy the moment he decided to take control.
"I'm not bored," Keith said, his voice sounding rough and hungry. "I'm just impatient. I've spent the last hour watching you sit there and pretend to be a good little girl while I could tell you were practically dripping for me. It's a very convincing act, Diana, but we both know what's actually going under that dress."
He shifted his position, moving one hand down to the small of her back and pulling her up from the chair and flush against him. Diana wrapped her arms around his neck, her fingers tangling in the hair at the back of his head, and she pulled him closer, desperate for the contact. He didn't kiss her right away, instead choosing to bury his face in the crook of her neck, inhaling deeply and leaving a trail of hot, wet kisses along her collarbone. Every touch felt like a spark of electricity, and Diana felt her resolve crumbling, her mind screaming for him to just take her right there on the dining room floor.
"Do you have any idea how much I've wanted to do this?" she whispered, her eyes closing as she felt his teeth graze the sensitive skin of her neck. "Ever since you came back, all I can think about is you touching me like this."
Keith pulled back just enough to look into her eyes, and the intensity in his gaze was almost overwhelming. "I knew you wanted it," he said, his voice a low growl. "I could see it in the way you looked at me, the way you tried so hard to look away. You've been craving this for years, haven't you? You wanted the one guy you weren't supposed to have."
Diana nodded, her breath coming in short, jagged gasps. "Yes," she admitted, the word barely a whisper. "I wanted you. I still want you."
Keith's expression darkened, and he suddenly gripped her waist, lifting her up and setting her on the dining table, pushing the plates and glasses aside with a careless sweep of his arm. Diana let out a small cry of surprise, but she quickly wrapped her legs around his waist, pulling him into the cradle of her thighs. She could feel the hard ridge of his erection pressing firmly against her, and the sensation made her moan, her head falling back as she looked up at the ceiling.
"You're so desperate," Keith murmured, his hands sliding up her thighs, pushing the fabric of her dress up until he reached the tops of her stockings. "I can feel how much you're shaking. You're practically begging me to ruin you, aren't you?"
"Please," Diana whimpered, her fingers digging into his shoulders. "Please, Keith, I can't take it anymore. Just touch me. Please."
He didn't give in immediately, instead choosing to torture her a little longer. He slid his hand higher, his fingers grazing the edge of her panties, but he didn't go inside. He just rubbed the fabric against her clit, using a slow, circular motion that made Diana writhe beneath him. She was sobbing now, the pleasure becoming too intense to handle, and she began to buck her hips against his hand, trying to force him to go deeper.
"You want it that bad?" Keith asked, his voice sounding cruel and seductive at the same time. "You want me to stop playing and actually give it to you?"
"Yes! God, yes!" she cried out, her voice echoing in the quiet room.
Keith let out a dark laugh and finally slid two fingers past the lace of her panties, diving deep into her warmth. Diana screamed, the sudden intrusion sending a shockwave of pleasure through her entire body. She was soaking wet, her walls clamping down on his fingers as he began to move them in a fast, rhythmic motion. He wasn't being gentle; he was pushing deep, hitting her spot with a precision that made her vision blur.
"Look at you," Keith whispered, leaning in close so she could see the triumph in his eyes. "Look at how you're reacting. You're not a shy little girl right now, are you? You're just a dirty little brat who wants to be filled up."
Diana couldn't even answer him, her mind completely gone, replaced by the raw, physical sensation of his fingers inside her. She felt the tension building in her stomach, a tight coil of energy that was about to snap. She gripped his arms, her nails scratching into his skin, as she felt the first wave of her orgasm crash over her. She let out a long, loud moan, her body shaking violently as she climaxed, her internal muscles squeezing his fingers in a desperate grip.
As the waves of pleasure slowly subsided, Diana lay there on the table, her chest heaving and her eyes glazed over. She felt completely undone, stripped of every defense she had ever built. Keith didn't pull his hand away immediately, instead staying inside her for a few more seconds, feeling the aftershocks of her release. He looked down at her with a mixture of possessiveness and hunger, and Diana knew that this was only the beginning.
"You're mine now, Diana," he whispered, his voice sounding like a promise and a threat all at once. "You might be able to play the innocent sister for Leo, but when you're with me, you belong to me. Do you understand?"
Diana looked up at him, her eyes filled with a mixture of love and fear, and she nodded slowly. "Yes," she whispered. "I'm yours."
Keith finally withdrew his hand and stepped back, adjusting his clothes with a calm efficiency that contrasted sharply with the chaos he had just caused in her body. He looked at her one last time, a smirk playing on his lips, before he turned and walked toward the garage.
"I'll be back in a while," he said over his shoulder. "Make sure you clean yourself up before Leo comes back inside. We wouldn't want him to wonder why you're breathless and shaking."
Diana stayed on the table for a long time after he left, her body still humming with the remnants of the pleasure. She felt a strange sense of peace, knowing that the secret was finally out, and that she didn't have to hide her desires from him anymore. But she also knew that by giving in to Keith, she had entered a game where the rules were written by him, and she had no idea how it would end. As she slowly slid off the table and began to straighten her dress, she could still feel the ghost of his touch on her skin, and she knew that she would do anything to feel it again.
