First Excuse that she can think of

"I'm not ... on the pill." Sandy desperately tossed up the first thought that might dissuade an amorous man. Clearly it was the wrong one, as Kelly responded with a peal of laughter.

"Oh ... that's good..." Kelly chuckled, her hands slipping down to pull Sandy against her harder. "Don't worry, baby, I'll take care of you..."

"No, that's not what I meant." Sandy stammered, feeling a surge of moisture running through her lower body as Kelly's hands roamed over her still clad ass.

"Mmm ... I see we're thinking the same thing though." Kelly grinned as she nipped at Sandy's neck with her teeth. "You want to take this to the bed or fuck me right here?"

The feel of naked flesh on her fingertips caught Sandy's attention as Kelly guided her hand along the exposed cleavage of her top.

"I want your cock, in my pussy." Kelly enunciated each word, drawing the maximum amount of sexuality out of each of them. "I want you inside me."

Sandy began to panic as she felt Kelly's hand sliding around her hip, aiming to cup at her crotch. She stepped back, her hands coming free of Kelly's clothes.

"Too hot." Sandy panted, taking a second step back, so that she pressed against the wall of the room. "I need ... need to cool off for a second."

"Were you ... You were just about to come, weren't you?" Kelly giggled. "Oh, my god, you have no idea how sexy that makes me feel."

"Can I ... I need to use the bathroom." Sandy breathed out, her breath still coming in deep, hot heaves. She could feel her nipples straining at their confines within her shirt, and hot moistness between her legs.

"Mmm ... and this costume's a pain to take off..." Kelly grinned. "Tell you what, you get ready, and I'll get comfortable."

"Ok ... ok..." Sandy nodded, stumbling backwards. Her feet found the tile of the bathroom, and she rapidly closed the door, pushing the small button that locked the door.

She breathed heavily for a few moments, amazed by how hot she was. She could feel her body primed, ready for contact. If Kelly had pushed just a little bit harder, Sandy was certain that there was no way on earth she could have resisted. With a final breath she dropped her jacket to the floor, followed by peeling the cartoon festooned t-shirt over her head.

With a soft scrabble at the tags holding her bindings into place, she quickly unwrapped her upper body. She was instantly aware of how little of her lung capacity she had been using for the last few minutes as the deep breaths she indulged in were nearly as pleasurable as the cool air on her erect nipples.

"And I have to ... Oh god, I really don't want to rewrap to go out there." She mumbled to herself, running a hand across her exposed body.

She ran a small amount of water in the tap, which helped clear her head of the fog of sex which had permeated it. Anything to get this arousal out of her system. She couldn't ... there was no way in hell she could sleep with Kelly and NOT have her secret exposed. It just wasn't possible. Well, short of racing home to get one of her hidden toys to serve as a substitute of course. Even then, she probably wouldn't get away with it, as Kelly had already exposed her love of risky sex play. There was no way she'd be satisfied with a fake orgasm.

At the thought of a fake orgasm, Sandy realized what the proper course was. While it might not get her out of sharing a bed with Kelly, it would at least serve as a plausible excuse why she couldn't go all the way with her.

How long did it take a man to roll over and go to sleep? A minute, five minutes? Sandy recalled from her own experiences that the general time frame was pretty short, so she quickly began to repair her appearance. The familiar tightness returned as she rewrapped herself again, and covered it with the t-shirt. She slipped her feet out of her boots, and held them in one hand, her arm draped with the jacket. All she wore now were the jeans and the t-shirt, in a passable appearance of masculinity. She tried to recall the dopiest expression she could, in the hopes of presenting a convincingly embarrassed visage of post-orgasmic male relief.

She swung the door open, to find that the light was still on, and that Kelly's costume was scattered over the floor, each garment leading towards the bed, where Kelly had snuggled beneath the remaining covers. Kelly looked up as Sandy exited, one large and fully erect breast very visible as she reclined on one arm.

"Hope you don't mind my playing a little while I waited for you." Kelly purred, her other hand not visible, but the gentle movements of the covers making it very clear exactly what she was doing.

"Kelly, I uh..." Sandy began, trying to inject apologetic embarrassment in her words. "You got me so hot that I ... well, when I was cleaning up..."

"Yeeees..." Kelly grinned, her hand moving slightly faster now. She placed her free palm on the bed and pushed up, the covers falling away from her luscious breasts. Sandy could tell exactly how aroused she was from one glance.

"I kinda ... in my pants." Sandy grimaced. "So I can't really..."

"Really?" Kelly grinned. "Well, that's good news."

"Good news?" Sandy asked, dropping her jacket and boots on the floor, and sitting on the edge of the bed. She tried not to stare at the exposed figure of Kelly, and found her gaze drawn to the other bed, where Nathan still slumbered.

"Sure. As soon as I get you ready again ... All night long, baby." Kelly leaned back, and with her free hand gestured to Sandy with a crooked finger. "C'mere."

"I don't think ... I don't think I can." Sandy repeated, hoping to dissuade Kelly. She hadn't thought this through well enough.

"It really is your first time, isn't it?" Kelly sighed. "Ok, stop worrying, and just come here, and kiss me."

It certainly wasn't Sandy's first time. She had just never been with ... Her mind started to panic as she lay down on the bed on her side. Kelly was so close now, and all she had to do...
