Eventually

Samantha scurried side to side on all fours as it was the closest she could do to pacing which was one of her nervous habits. She was cold, naked, and a mess as she was trapped in a ditch with her leash attached to a branch above her holding her in place by her collar. She went as far as the collar would let her but she couldn’t free the leash and if she tried to stand her collar would shock her so painfully she immediately fell back down. Still she tried it several times and each time her legs gave out and she’d land roughly on her ass. Tears ran down her cheeks as she realized her sister was loving all of this.

As more time went by and the cold became more unbearable she gave up on trying to free the leash and went into the fetal position laying on her side, trying desperately to get warm. Her stiffened nipples pushed into her knees as the cold air wrapped her body on one side and the wet mud was under her on the other. Her only hint of what time it was the sun above the trees and it seemed to about mid-day. She shivered hoping no one would find her as she felt the air tickle her pussy and asshole. She couldn't believe she had masturbated earlier as she was now horrified by her pussy's wetness in this situation.

She heard the sounds of twigs cracking under shoed feet and held her breath hoping they'd turn around or give up. She pushed herself as far as she could against the wall of the ditch trying to make herself as small as possible.

“I’m sorry, but you might want to call security or something because your dog is very lost.” Said one man yelling back towards Tiffany.

Samantha contemplated exposing herself to these men and begging them to save her in anyway she might communicate but for all she knew Tiffany would tell them this was some sick fetish she was into and that her resistance was all for show as she let them tag team her. She couldn't risk it. She could only rely on herself.

"Aw, I guess I'll have to. Thank you for trying you're both very sweet." Said Tiffany.

"Happy to try to help, miss. You know after our round we'll be heading to the bar in the lobby, might we see you there?"

It was an obvious come-on but Tiffany just answered in her sweet voice "You just might."

The sound of the men turning around and heading back to the concrete path was the closest thing Samantha had had to a win since this whole day had started. She continued to hold herself in the fetal position until the she couldn't hear their steps anymore. She got back on all fours and tried a few more times to free the leash from the branch it was stuck on but limited to not being to stand up she couldn't get it to budge. She went back to pacing and tried to think of any recourse she might have.

It seemed like an hour had gone by when she heard the twigs begin snapping near her. She hoped it was another animal and a friendly one at that. Then she reminded herself she was not an animal and was hoping it was an animal unlike her who was a person. She held her breath.

"Oh sister, you had me so worried."

It was Tiffany and her voice was thick with malice. Samantha began to cry again as she knew she wasn't going to help her get out of this situation and was actively enjoying it. She looked up at her sister who stood on top of the fallen tree she had tripped over earlier.

"I saw the leash on the branch when the men were here but I had no intention of letting them actually find you. Just was having a little fun. Then I gave you some time to think about how you shouldn't be hiding from your sister so I went and had some dinner."

Samantha's stomach gurgled as she realized she hadn't eaten all day. She realized that on top of everything else she would need to rely on her sister to feed her if she so chose.

Tiffany hopped down and grabbed the leash from the branch freeing it easily with her full range of motion. Samantha knew she trapped but she felt she had to try fighting back. She dove at her sister's legs who dodged her easily and was now standing behind her.

"With all that mud I can still see that wet puss and pink b-hole. I don't think most girls would be wet in this situation, slut."

Samantha sobbed knowing she might be right, but she couldn't control her body's reactions. She started to turn back towards her sister when she felt her right nipple grabbed and twisted. She yelped and felt a terrible shock and her face fell forward towards the ground.

"I have done everything for you today and you think you can attack me?!"

Holding her twisted nipple Tiffany then spanked Samantha with five quick smacks on her ass. Holding her mouth shut as tightly as possible Samantha just let the tears roll down her face to not get shocked. Her sister then kept holding her twisted nipple on her small breast but began caressing her sister's bare ass which was actually a small relief from the spanks.

"there, sweet girl. There, there. Now let's get you a bath."

Samantha did want a bath but she wanted freedom more. She wanted to be clothed and not collared, and she wanted to forget any of this had ever happened. Tiffany released Samantha's nipple and stood over her with a firm grasp of her leash. She began walking and Samantha had **** but to follow on all fours as she was led back towards the concrete path through the bushes that would poke at her and when she pushed them out the way would often whip her across the tits. Tiffany would look back and snicker as Samantha was trying not to bawl for fear it would result in a shock if she made any noise.

Once on the path she looked frantically to both sides to make sure no one could see her naked mess of a self and they started to go towards the bathhouse. Tiffany was now walking behind her and Samantha in front and Samantha knew that was so she could leer at her ass and pussy.

The trees started to become less prominent on each side and Samantha knew that meant less coverage and potential exposure. She tried to control her breathing as the rough concrete under her hands and knees made her all the more aware that she was stuck like this maybe for the rest of the vacation, or maybe even forever. She just focused on the bathhouse and kept moving.
