[Chapter 4]

Kate pushed Rick onto the large king-sized bed, his legs ending up hanging off the sides. She sauntered over, kneeling down so that her face was directly above his. Kate was upside down from Rick's perspective. Lowering her head, she stared down at his smiling face.

His deep blue eyes were flickering with excitement, and he smiled at her, leaning up for a kiss. Their lips met, softly as first and then they slowly increased in pressure. It was kind of erotic kissing upside down, and Rick could quickly feel his body begin to respond to the heat of their kiss. He moaned into her mouth, and brought his hand up and rested it on the back of her head, forcing her closer to his needy lips. Kate could feel Rick's tongue trying to find its way into her mouth, and she caught it between her teeth, giggling.

His hands were roaming her body, coming to rest on her breasts and she moaned as he pinched her erect nipples through her shirt and bra. Kate broke the kiss and moved over so that she was now straddling him. She ravaged his neck, biting and sucking until there was a little mark. She smiled, and began to caress his bulge through his pants. Rick's eyelids fluttered closed and he moaned her name as she ran her delicate fingers over him.

She brought her fingers to the hem of her shirt, and pulled it slowly over her stomach. Kate shook her hair out as her shirt was finally removed. Rick ran his callused fingers over her silky bra, and finally slipped underneath. She threw back her head in ecstasy as he squeezed and teased her pert nipples. She looked at him with clouded eyes and began to slowly undo his pants, moaning in appreciation as his member was unveiled to her. He looked at her with eyes darkened with desire and Kate knew what was about to happen next...

He slowly brought her to him and went in for a kiss, kissing her lovingly and softly. Rick cupped her ass, earning a deep moan from within Kate. He tugged at her pants as their kiss, once again, became more intense. She lifted up her ass so he could remove the offending clothing keeping him from her center and he ripped off her panties.

Rick sucked on her neck, causing her to gasp and shiver in his arms. He bought his hand down to himself, and slowly guided his member into her warm crevice. Both sighed in satisfaction as he pushed his way into her. They sat there for a second; both too lost in the feeling of being one to move at all. Rick eventually began to move his hips, sliding himself in and out of her. Kate threw her head back and let out a squeak every time he thrust into her.

He then flipped them over so that he was now above her, and she instinctively wrapped her legs around his middle. Rick couldn't believe how wonderful she was. Her face was a mask of complete pleasure, and her little pink tongue would poke out every so often to moisten her lips. Kate was so wet, and he could tell that she was close to her peak. He was nearing his own, and every thrust would bring groans and screams from both of the lovers.

"Ooh...faster," Kate yelped, eyes shut and mouth agape.

Rick obeyed, thrusting faster and faster until she screamed. Her walls collapsed around him, tightening and convulsing. She rested her head on his shoulder as he pumped harder and faster into her, and finally he came.

He grunted loudly into her hair, "Kate..." He bit into her shoulder as his body was once more consumed by the power of his orgasm.

The two laid there, panting and sweaty still joined at their centers. A few minutes passed before Rick removed himself from Kate, pulling her flush against his chest as he yanked the blanket up.

"My God, you're incredible," he breathed, raising a hand to a strand piece of hair and tucking it behind her ear.

Kate smiled, "You're not so bad yourself, Rick." And she closed the distance between them, their lips meeting in a sweet kiss. Rick broke away first and stared at the woman in his arms, love shining through her chocolate brown eyes as she, too, stared at him. Her smile grew sinister as she huskily asked, "So...Writer Man," putting emphasis on man. "You ready for round two?"

Rick growled, "I thought you'd never ask." Repeating her words from earlier as he pounced her, attacking her mouth with his own.

The two lovebirds never left the bed for the remainder of the night. The cold snow storm was melting from all the heat coming from the bedroom...

"There's bound to be talk tomorrow (Well, think of my lifelong sorrow)

At least there will be plenty implied (If you caught pneumonia and died)

I really can't stay (Get over that hold out)

Oh, but baby it's cold outside."

There you go!
