Be a gentleman---volunteer to sleep on the floor

"Neither of those beds is big enough for two people," frowned John. "I'll just sleep on the floor; you two take the beds." He grabbed some extra pillows and blankets from the closet and began to arrange them on the floor between the beds in a makeshift nest for himself.

"You don't have to do that," Kate allayed, "Ilyana and I can fit on one bed..."

"Nonsense," he maintained, continuing his preparations. "I don't want to be any inconvenience. Just pretend I'm not here. In fact, if you need anything---anything at all---just ask. It's the least I can do to repay your hospitality."

Kate was silent at that, and after a moment he looked up to find her blushing furiously at some unarticulated thought. Before he could inquire, Ilyana came to her rescue.

"Problem solved!" she cried triumphantly, hauling out a fold-up cot that had apparently been uncovered by his removal of the spare bedding from the closet. Together they set it up between the beds. It just barely fit and was the same height as the beds, so the finished product looked a bit like one large sleeping surface. He kind of liked that idea, but hoped it wouldn't offend the girls' sense of propriety. Fortunately they didn't seem to notice.

"Well," Kate sighed after they had finished, "I know it's only 10:00 but I'm beat. I think I'm gonna get ready for bed."

"Me too," joined Ilyana, following her into the bathroom.

As he waited for the bathroom to become available, John set about the task of digging his various nighttime accoutrements out of his luggage. Toothbrush, toothpaste, sleeping shorts... Suddenly he realized he had a slight problem. He was accustomed to wearing just a pair of boxer shorts to bed, and hadn't even brought any other form of bedclothes with him. Scowling, he rooted through his luggage for some more modest alternative. Eventually Kate, who had emerged quietly from the bathroom while he was rummaging, interrupted him.

"Anything the matter?" she asked.

He looked up and his eyes almost fell out of their sockets. Kate had changed into a white, semi-translucent, babydoll nightgown that ended just below her hips. It swished slightly as she walked, constantly threatening to expose all but somehow just barely managing to avoid any obscene exhibitions. The neckline was fairly conservative, arcing horizontally below her shoulders, but below that it billowed outward following the contour of her breasts until they released it to drape the rest of the way unsupported. Beneath the sheer fabric he could just barely see the points of two petite, rosy nipples punctuating the smooth flow.

Even though John had secretly lusted after Kate from afar for as long as he could remember, and even though he'd had plenty of opportunity to admire her physically during meets and practices, he'd never seen or imagined her like this. Her wardrobe had always been so conservative. Even in a leotard, she always had everything tightly under wraps so that nothing showed or bulged or jiggled. But now, with her body free of the usual restraints, he was floored by her beauty. How had she managed to keep a body like THAT hidden??

After what seemed like an eternity of utter incoherence that he desperately hoped was actually just a few seconds, he tried to recover himself and remember what in the world she had asked him and what he was even doing.

"The matter? No, no, nothing's the... Oh uh well it's just that to bed I usually just wear these and I wasn't sure..." he rambled, holding up a pair of his own underwear like a complete idiot.

"Don't do anything different on our account," Kate responded firmly, studiously transferring her shirts to hangers. "It's like you said: No inconvenience. Just pretend I'm not here."

Yeah. Right.

Just then the bathroom door opened and Ilyana stepped out. "Bathroom's free!" she announced.

John's heart came to a second abrupt stop as his eyes fastened upon her. She was wearing an almost identical outfit to Kate, except all in black. Either the two girls had fantastically similar taste or they were shopping partners. Either way, Ilyana was ravishing. Her dark eyes, long lashes, and olive skin tone drew the sheer nightgown around her like a sensual cloak. Most of her torso was tantalizingly concealed, but two large, chocolate-colored areolae proudly enhanced her ensemble with bold, painted discs where her full breasts emerged to touch the fabric.
