Getting ready for the beach

Samantha waited for her sister to come out of the bathroom trying to accept the fact she was going to the beach while dealing the fact that her bottoms concealed two dildos, one in her ass and one in her pussy. She was standing awkwardly trying to find the position that stimulated her the least but each shift pushed them in or out causing a deep moan that she feared her sister would hear. She looked down and watched as juices leaked out the leg holes of her bottoms and wondered if just accepting being a pet was better than this. However if her sister actually intended to keep her promise she knew she had to survive this to show she wanted to be treated as a person.

Her sister walked out of the bathroom wearing sandals and a long shirt concealing a bathing suit with a beach bag over her shoulder.

“Okay, here’s the deal, I know you really think you’re a person but I also know what you really are. So if at any time you decide you want to go back to being a pet all you have to do is yank your bottoms off and that’ll be your signal that you’re ready for a full commitment to your true self. I know you might be tempted to keep them on just for your own pleasure but don’t worry I have ways to help you with that when you’re a pet too.”

Samantha just nodded as she could barely focus. All she really understood from that is if she wanted to stop being double penetrated she’d be telling her sister she accepted being a pet essentially trapping her in a horrible situation to avoid an even worse one.

“Okay, let’s get going.” Said Tiffany.

Samantha’s eyes shot open as she frantically pointed to her own small chest. She hadn’t been given a top yet.

“Yes, I know you have small boobs if they can even be called that.” Said Tiffany.

She winced and placed her hands over her breasts on her hard nipples and flipped her hands out then back trying to imitate putting a top on. She moaned from the lightest touch given how stimulated she was from her double penetration.

“what are you trying to tell me?” Asked Tiffany smiling.

Samantha dragged her hand over her chest again trying to imitate putting on her top. She moaned again.

“Oh I get it, silly. It’s a clothing optional beach. Not that you would need a top either way.” She said chuckling.

Samantha didn’t know if it was clothing optional but she also knew even if it was people didn’t go their already in a state of undress; they wore their outfits there and then stripped down at the beach. Still she could barely focus with her pussy and rectum completely filled and wasn’t sure if she could trust her own doubts or anything she thought for that matter.

Her sister held out her hand.

“Come on let’s go, Samantha.” Tiffany emphasized her name to stress she was being treated like a person but only if she went along with this.

Samantha realized she would be going to the beach topless, collared, and impaled in both her ass and pussy if she really wanted to meet her sister’s challenge.
