"It can be anything you want," Jack said huskily, gripping her thighs as she straddled him. Kate rubbed against him and Jack growled

"Let's see what could we play ?" Kate asked innocently, running her finger over his chest. "How about we play a little dress up ?" she smiled and pressed against him.

"I don't have any costumes baby," Jack sounded dissapointed, although his finger's still gently massaged her thighs.

"You may not, but while we were getting Aaron back, I did a little secret shopping of my own and I got a few things I thought you'd like," she said running her tongue over his neck.

"Oh God, baby, get up those stairs and change right now," Jack growled and Kate smiled at him.

"You stay here and I'll be right down," Kate whispered and slid off his knee. She made her way upstairs and Jack sighed. He massaged himself through the denim of his jeans and sat back on the sofa. Jack heard a noise at the door and he looked up. His jaw dropped and he hardened even further in his jeans. Kate was leaning against the door frame in a short pleated skirt, a white, almost see through blouse and a tie. She was dressed like a schoolgirl. Jack walked to her and she wrapped her arms around his neck.

"I've been very bad sir," Kate said, and Jack's jeans became unbearibly tight. He ran his gaze along her body.

"Why's that ?" he choked out and Kate stepped away from him, her finger danced across her bottom lip and crossed the room to sit on the couch.

"Well I've been doing really bad in my homeworks. I don't really get the whole sexual intercourse thing," she said in a small girly voice.

"Don't you now ?" Jack asked huskily.

"No. I wondered if you could help me," Kate said.

"What do you need to know ?" Jack asked as his whole mouth went dry.

"Anything you can teach me Mr Shephard," she said fiddling with her tie.

"Well first of all let's get comfy," Jack said and he sat on the sofa, pulling her onto his lap. Kate moaned slightly as his erection rubbed her thigh and she straddled his lap. "Now, lets see," Jack said, sliding his hand under the skirt. "First I get to make you feel really good," he kissed her neck and cupped her under the skirt. One of his finger's slipped inside of her and Kate almost purred in pleasure, grinding her hips into his hand. Jack's thumb circled her clit and he added another finger inside of her. Jack pumped his finger's inside her and kissed her neck. Jack's fingers moved into her faster and Kate went over the edge, her muscles squeezing around his fingers. She cried out his name, her head falling onto his shoulder. The warm slippery fluids flowed onto his finger's and Jack removed them from inside of her. He brought his hand to his mouth and licked them clean.

"Please Mr Shephard, please come inside me," Kate moaned.

"Your learning quickly Katie," Jack said as he unbuttoned her shirt and unzipped his fly. Jack sighed in relief, finally releasing himself from the rough demin. Kate rose up and plunged down onto his hard member, engulfing him in wet heat. Jack groaned as Kate moved faster, grinding her hip's into his. Jack's hands went to her tender breasts, massaging them and causing Kate to gasp. Kate arched her body into his, rubbing against him.

"Oh Mr Shephard your so big," Kate purred and Jack thrust into her harder.

"Well baby your so tight. I love being inside you," Jack growled.

"I'm so wet for you," Kate panted, snaking her arms around his neck, to play with the soft brown hair at the base of his neck. Jack moved his hands under her thighs and lifted them up from the sofa, so that he was standing up, with Kate still impaled on his hard member. Kate slipped down further onto him and cried out. Jack moved to the wall pressing her against it.

"Why did you OH GOD ," Kate cried out as Jack moved faster. "Why did you do that ?" she panted as he hammered into her.

"Just wanted to," he growled into her neck. Jack's tongue flicked out onto a sensitive part of her neck and Kate moaned, tingling sensations running through her body as her orgasm began to build.

"Please baby come with me," Kate begged as Jack pounded into her. Kate started to move her hips in time with his, meeting his thrusts with small wet slaps. "Please Jack, baby please I wanna come with you," Kate cried. With two solid thrusts Jack exploded inside her, pumping his hot seed through her as Kate went over the edge, clenching her muscles and screaming his name. Jack's forehead dropped onto hers, their combined panting the only thing to be heard in the room. Jack kissed her, his tongue exploring every inch of her mouth. Kate pulled away and grinned at him.

"Did you enjoy our game, Mr Shephard ?" she asked.

"You bet I did," he laughed and slowly let down her legs so that she could stand. He pulled out of her and Kate whimpered slightly from the loss. They lay on the sofa and soon they were asleep.
