I feel that this one might be bordering on an M rating, but it's not quite there yet. There's nothing graphic in it, but there very well could have been, so read at your own discretion. And don't blame the poor author if this leads to dirty thoughts.
Steamy Nights, Twilight
She gasped quietly as she felt his cold hand on her neck. He gathered her long, chestnut brown hair in his hands and swept it away from her neck and shoulders.
"Bella, I love you." he whispered as he pressed a light kiss to the bare skin of her shoulder. Bella felt a chill run down her spine. She tilted her head back, giving him better access to her neck. This is what she had been longing for.
"Edward, don't stop." she sighed as he continued to kiss along her neck and shoulders. She felt his hands running along the back of her dress, unbuttoning it slowly, his lips never stopping their path along her neck.
As Bella's dress fell softly to the floor, Edward's hands gently caressed her body, while his lips began to travel toward her chest. As he kissed the place right above her heart, she sighed softly, lost in memories of such a night, long ago.
Bella shakes herself out of her distant memories to concentrate on the joy of here and now. Edward's lips make their way back to her neck, his hands still passing a gentle touch over her stomach. Bella finds herself nearly melting at the feel of his hands against her skin. She cried out in a moment of pain as his fangs pierced the tender flesh over the vein in her throat.
The pain quickly fades, but she can feel her blood and life force slipping through her veins. She feels herself fading slowly, slipping into unconsciousness. Her heartbeat slows and her breathing becomes shallow. Edward tears himself away and looks at her with red rimmed eyes. The next second, Bella is alone in her room, clutching a hand to the wound at the base of her throat.
This is the last one I have floating around my hard drive at the moment, so now I'll have to rely on your prompts. So please send me some. Seriously, anything you want me to write about.
