It was some time after dawn when Sarah awoke. In her early Saturday morning haze, she hadn’t the presence of mind to check the clock. She was barely aware of anything for the first few minutes, just the sound of the birds outside and the wind rustling in the trees outside the house. A cool draught wafted in through her open bedroom window and tickled at her extremities. The satin bed sheet was folded messily across her middle, leaving most of her uncovered.

She rose slowly, shaking off the lingering drowsiness, and made for the door. By now breakfast would surely be ready. She wouldn’t want to be late.

Before leaving her room, however, she paused in front of the mirror to marvel at the sight of herself.

Her new sleepwear was every bit as lovely as Taffy had told her when they’d picked it all out, as it should be; she’d been on quite strict orders to that effect. Sarah blinked away the last of the haze and took a good long look at herself, smiling at her reflection. It seemed like only yesterday she’d been half as tall as she was now, and her body had blossomed into quite the appealing figure. She put both hands under her bosom and pushed, giggling at the effect.

The outfit she’d finally decided on was a two-piece number much like its predecessor, but far less innocent in nature. The petite scrap of a top was barely long enough to reach her belly, with a neckline cut rather conservatively close to her collar and loose-hemmed sleeves that reached her elbows. Thankfully, much of the front was cut away around the tops of her breasts and then down her sides so that only the back reached the edge of her ribcage, and her rapidly growing womanly charms were always on display. Just the way she liked it. The soft pink satin brushed against her with every movement in just the right way.

Feeling quite mischievous this morning, she watched herself closely in the mirror as her fingers wandered around the incredibly low waist of her matching shorts. Down they slid along her thighs with a whisper, and she stepped out and kicked them off onto the bed. A skirt replaced them, matched with the rest of the outfit, but definitely not intended for sleeping as its pleated hem skirted the tops of her thighs in the front and didn’t even come halfway down her buttocks in the rear.

Sarah looked at herself again and giggled.

Coming down the stairs towards the kitchen, she was brought to a halt by the sound of hushed conversation. Two voices drifted through the open doorway and up to her ears; one soft, sultry and sweet, the other low and sensuous in tone.

“Well it might take me a while,” said the first, replying to something she’d missed.

“Are you trying to suggest something?” Sarah recognised her adoptive sister’s voice in a particularly erotic mood. The sound made her thrill even more at the prospect of being discovered.

“Suggest?” The other voice laughed high and sweet, and Sarah knew that laugh straight away. “I’m not suggesting anything,” Taffy explained, “I’m just saying that there’s quite a lot to work with.”

“Are you saying I have a big butt?” Rachael sounded faintly perturbed, but far more horny.

Sarah slipped in through the kitchen door to see her elder sister leaning up against the breakfast table with her tail raised, tip flicking impatiently, pointing an irritable expression back over her face that failed to hide her early morning lust. Her manner of dress was far more plain, but her current favourite black jeans were mostly tangled around her knees and her underwear, a tiny little sliver of silvery-white fabric, was halfway down her thighs.

“Quite large,” agreed Taffy without a hint of apology. In fact, she seemed in good humour despite the redness in her face. The fact that she was wearing only her sky blue apron and a smile might be the cause of that. “But I like you just the way you are, sweety. That includes your big ass.”

“Morning!” Sarah bounced into the room with her usual energetic smile right on time. She found her sister’s eyes on her just as Taffy’s nose went down beneath that squirming tail. Before she could say anything, or react to the sudden presence of her barely-dressed young charge, Rachael was assaulted by the sensation of a hot, smooth tongue twisting and pushing slowly into the ring of her anus.

“How…ah…many…” she began, and trailed off immediately. Between the sight of Sarah’s shameless exhibitionism and Taffy’s incredibly talented tongue, she practically creamed herself unconscious. She collapsed over the table with a breathless sigh.

“What a wicked young girl,” Taffy remarked as she rose from kneeling on the kitchen floor, dusting off her apron. “You really shouldn’t do that to your poor sister. You know she doesn’t like it.”

“Nobody told you to stop.” Now Rachael’s voice was coming through clenched teeth.
Taffy obeyed without question, back down on her knees in no time and pushing her nose between those gorgeously round black cheeks. Her cute puff tail flicked back and forth as she worked in a way that made Sarah want to go over and squeeze it. Her ears were half-cocked, rising up high and then curling over to either side so that the ends brushed both sides of her head. They twitched slightly every now and then as she worked diligently on Rachael’s backside with her tongue.

Sarah slid around the room to stand up against the refrigerator. After nabbing herself some juice, she lifted the edge of her tiny little micro skirt up and started slowly masturbating the way Taffy had showed her, making sure her sister was watching.

“You’re heading for one hell of a spanking later, missy.”

Sarah just laughed.
