Need

Kitty felt Kurt's hands on her hair. He was tugging her upward and toward his mouth. She dropped the tattered remains of her shirt and bra beside him and dragged his own t-shirt up with impatient hands. His chest was lean without the bulkiness that Scott and Logan had. His arms and torso were tightly knotted with muscle and there was barely an ounce of fat on him. The short fur that covered most of his body wasn't fine like a cat's but slightly coarse beneath her fingers. She kissed his chest and ran her tongue over one of his nipples before reaching his lips.
When Kurt kissed Kitty on the mouth for the first time, he felt like he was sticking his tongue in an electical socket. A sweet, soft electrical socket, but one charged with enough voltage to make him feel like his hair was standing on end. He kissed her with a deep hunger that echoed her own. He loved her dearly, he had for as long as he'd known her, in one way or another, but both of their actions were completely unexpected. He had never felt more out of control than right now.
Kitty allowed sensation upon sensation ile ile up until she felt like she was drowning. Kurt's lips and hands were doing amazing things to her and she never wantem tom to stop. It was the sound of the danger room doors opening that broke them both from their passion induced fog. Tightening his arms around her, Kitty felt Kurt tense a split second before the world dropped out from under her. A moment later, she felt a hardwood floor beneath her knees. Kurt had teleported them to his bedroom in order to avoid discovery. He didn't break stride. She was a little unnerved by the sensation of teleportation, but it was driven from her mind by what he was doing to her neck and breasts.
Kurt was whispering endearments to her in German. Over the years, she'd picked up a few phrases, and what he was saying made her blush. He pressed her onto her back and kissed his way down her chest, stopping at each breast to suck and nip. Then he moved down her belly and to her shorts. He pulled the damp lycra down her thighs and discarded it. Then he grabbed and ankle in each hand and pulled her onto his lap wrapping her legs around his waist. Her damp and naked flesh came into contact with the cotton of his sweatpants. She could feel the hardness of his erection throbbing through the material that separated them.
Kurt's tail brushed lightly down Kitty's delicate spine and traced the cleft of her buttocks, giving her a thrill when it moved underneath her to stroke at her moist opening. She kissed his neck and ran her tongue along his ear. Then she sucked the lobe into her mouth, illiciting a savage growl from him. Kurt was on his feet in a second, but instead of heading for the bed, he only made it as far as wall, pressing her back into it.
"Liebchen." He gasped, "I cannot wait any longer." Kitty nodded frantically, feeling the smooth wall against her naked back.
"I'm on the pill, it's okay." Letting out a groan, Kurt used his tail to stimulate her while he pushed down the front of his sweats. Gripping her buttocks tightly, he placed himself at her entrance. Kitty tightened her legs around his waist and waited, holding her breath. He eased the tip into her snug dampness and sweated with the strain of holding back. He allowed her to slide down onto him with agonizing slowness that had her writhing impatiently for the fullness shavedaved inside. Feeling her stretch around him was too much. He caught her lips with his own and hooked his arms under her knees, spreading her legs wide. He braced his hands against the wall and began to thrust.
Slowly Kurt moved in and out of Kitty's tight sheath. She moaned against his lips.
"Please Kurt." She begged, "I need you, I need….faster." He buried his face in her neck and obeyed. He began to pump harder and rocked his hips upward in a fast rhythm that had them both gasping and panting like they had been in the danger room. With his tail, Kurt continued to rub her clitoris until he felt her begin to contract around him. Kitty's nails dug into his shoulders with a pain that sharpened his desire. He bit her neck again, though not as deeply as before. The contractions he felt around himself were more than enough to drive him over the edge. He called out her name and pounded into her fiercely as he came, pumping his substance into her with each spasm.
When Kitty's vision cleared, She felt Kurt's damp head resting against her collarbone. He was breathing as heavily as she was. Slowly he lowered her legs until her feet touched the floor. His shirt was bunched up under his neck and she absently tugged it back into place. Kurt withdrew from her slowly and Kitty felt the sticky wetness between her legs that resulted from their primitive coupling. Not knowing what to say, she cast her eyes downward. She hadn't planned any of this, but it was done now and there was no going back. She rested her hands on his shoulders as she waited to se if her aching legs would support her. Kurt cupped her face in his hand and kissed her firmly on the lips. Then he backed away.
Noticing the smear of blood on his wall from her shoulder, Kurt's stomach fell and he immediately felt ill from how violently he'd taken her. He turned from her and opened one of his bureau drawers and pulled out a clean t-shirt. He pressed it to the wound on her naked shoulder. Kitty's forehead wrinkled as she felt real pain for the first time. Earlier the bite had barely manifested as just one of the sensations that she'd been feeling. Now all of the aches and pains she'd endured during their session in the danger room were coming back to her as the sexual adrenaline wore off.
