Arf! Arf!

Her phone buzzed an unfamiliar sequence, and on instinct Elizabeth blurted out "Arf! Arf!" Megan grinned wider, and felt herself get wet. "That's what I want to hear!" She dangled the truffle over Elizabeth's face as she barked playfully, "Arf! Arf! Arf! Arf! Arf! Arf!" Her barks got more and more shrill, until they sounded almost perfectly like the yips of a little excited dog. Megan could feel an arousal building in her, holding a treat over her sister like an owner and a pet. Eventually she dropped the truffle into Elizabeth's mouth, and **** a laugh as her sister munched it happily. "Good girl, Ellie, good girl." Elizabeth beamed unironically, the truffle sending endorphins into her system.

It was a busy next few days after that for Elizabeth. She lost track of how many times her sister asked her to get something for her. She hardly read the texts, she just felt a sequence of buzzes and knew what she needed to do: come here, sit down, fetch something, beg, speak, good girl. The phone had a slot in the back for a strap to go through, so she'd just put it on a lanyard around her neck to make it easy to carry, and she could still feel the vibrations. A few times Megan didn't even want her to fetch anything, just sit at the desk and keep her company. There weren't any other chairs in the office, so she grabbed one of her new pillows and sat on the floor.

She couldn't explain it, but it just felt really, really good every time Megan would call her a 'good girl'. So good that she'd started to get a familiar feeling between her legs, which she'd tried to ignore. She didn't feel that way about her sister, it just felt really, really good to obey her for some reason. Unfortunately, she was following enough tasks for her sister the last few weeks that the feeling of arousal was now constant. With no man nearby, her impulse had been to purchase a dildo while she was out fetching something at the mall. She kept it in her room, hidden under the pillows. She used it a couple of times a day.

That coupled with very weird dreams she'd been having. She only half remembered them, but every time she would wake up from one, she could swear her phone was buzzing at night. She'd been sleep walking as well, and found herself waking up all over the house: on the kitchen floor, at the foot of her sister's bed, in the bathroom; everywhere she was either lying down, or woke up as she was on all fours. She'd lost her phone one night, it had slipped off her neck while she must have been sleep-crawling. After that, she'd taken to doubling up the lanyard so the phone hung almost at her neck. It made it impossible to see the screen, but she didn't need to read it anymore anyway with the vibration sequences.

Her new phone buzzed around her neck in a sequence she didn't recognize, and it took her a few minutes to unclip it to read the text. It took her forever to read the tiny writing, especially with the constant flickering. She found herself having to sound out the words.

"Who is it?" Her sister called from the bathroom.

"It's my... husband." She called, hesitation in her voice for a second.

"What did he say?"

She read the message. "It looks like the post office called him, they might have lost the package with the key fob. So I might have to stay here a little longer. Maybe a few weeks."

Megan's heart leapt. "Well of course, this is basically your second home now anyway, Ellie. We need to do something about that lanyard though, its basically **** you."
