He was sitting on the sofa opposite the door, reading by the light of a lamp on the table next to him. Other than that, the room was in darkness. It made her shiver; she didn't know if that had something to do with the fact that he wore nothing but a pair of loose slacks or that she was in nothing but a bathrobe. Rosie was asleep at that moment and Sienna thanked whatever higher power there was that her friend was a deep sleeper. Jason didn't know she was here. He had come back from the gym, taken a shower and gone straight to his room. But she knew he watched her constantly and she was smart enough to know that his eyes darkening when he had seen her slip out of the pool only hours before had not been a trick of the light.

She took a deep breath and reconsidered her idea. It was reckless and stupid, but she was tired of being so careful. Even now, she was squeezing her thighs together to control the feeling she got just by looking at him. Sighing, she ran a hand through her hair and walked through the open door with her head held up. His eyes shot up to meet hers and he raised an eyebrow.

"Sienna?"

She didn't answer, merely strode up towards him and planted herself in his lap. His mouth fell open, specially when her robe parted slightly to show her lack of clothes. His eyes strayed there and became transfixed. Sienna smirked to herself.

Her nails were long. She trailed them over his muscled chest, slightly harder than necessary, enjoying the marks they left behind. Her hands shook slightly, but he had not noticed. He finally tore his eyes away from her chest and opened his mouth to speak, but Sienna promptly readjusted herself so that she was straddling his lap. He shut his mouth abruptly. She winked. "Hi, Jason."

"Hey," he had to force himself to sound calm. "Uh, what's going on?"

"Oh, nothing much," she continued to trace his muscles absently. Her thumb brushed against his nipple and it hardened deliciously; she had to resist the urge to lick it. "I was just wondering if you could do me a favour."

"A favour?" His voice was steady now. She felt his hands grip her waist and reposition her so he could see her face. Sienna almost gasped. The bulge now pressing against her core had become incredibly prominent. "Depends on what it is."

"Oh, its nothing too big," she assured him. Then, with a wicked smile. "Actually, it might be."

She didn't know where all this courage was coming from. She had always been incredibly tongue-tied in front of Jason since they were children. Her 12-year-old school-girl crush on him had evolved, however. It now comprised of raw, sexual attraction. Maybe that was where her new-found bravery had come from.

"The bigger the better," she almost fainted when he winked at her. She bit her lip and saw his gaze linger. "What did you have in mind?"

She didn't respond. She didn't think she could. Removing her hands from his chest, she undid the belt of her robe. Before she could do anything else, his warm hands were pushing it off her shoulders. His face neared hers and her eyes fluttered close. His scent was overpowering. She felt his hands palm her chest. Her nipples were so hard they hurt; he pinched them and she moaned quietly. He chuckled in her ear.

"This what you had in mind?" He whispered. One hand continued playing with her tits but the other went lower, towards her stomach. "Or maybe something like this?"

She was surprised he couldn't tell how wet she was. She groaned when his hands left her. "Don't stop," her voice was breathy.

"I have no intention of stopping," his hand caressed her stomach. "But you're going to have to tell me what you want."

"I'm sure its obvious," she gasped out as his hand brushed against her inner thigh.

"Maybe, maybe not," he had parted her thighs slightly and was running his fingers up and down the inner sides. It was making her crazy.

"Jason…" Sienna moaned as his hand came dangerously close to her wetness. She heard him chuckle.

"You're so wet for me," his voice dropped to a whisper again. "Is this all for me, Sienna?"

"Yes," she shut her eyes as his fingers pinched her nipples again.

"Good. And what do you want me to do with you?" he pinched her harder. She moaned quietly. "That's not good enough, babe."

"You know what I want," she murmured.

"Trust me, I know," he pressed her hard against his chest, crushing her breasts against him. Sienna released a shaky breath. "I know exactly what to do with you."

"Then do it," her eyes opened to see his expression. He wanted her, she could tell. "Do it, Jason."

He dug his fingers into her inner thigh. Sienna's eyes rolled back into her head. Everything he did to her felt so good. His breathing was coming in shorts gasps now, but his warm breath against her collar-bone surprised her. "Say it, and I'll do whatever you want."

She couldn't hold back anymore. "Fuck me," she breathed out.
