"Do you really have to gag me with THOSE?"





Heather held her head back as her sister Kate held a pair of dirty panties to her head, gagging on the horrible odor the dirty laundry was making. To make matters worse, she was already tied up to a chair in her catsuit, so she had nowhere to run.





"Sorry sis, but you agreed to let me gag you if I won the bet. And I won, so I get to choose the stuffing." Kate said with a grin. The bet in question was a test of endurance, who could stay awake the longest while listening to Heather's daughters talk about science stuff. Heather lasted a full 30 minutes before shutting her eyes.





"I know I lost, but do you really have to gag me with that? It's so bad, everyone in the house can smell it!" She recoiled in horror as the panties moved closer to her mouth.





"That's what makes it so fun, so don't fight it sis." Kate reassured as she jammed the panties into her mouth. 





MMMMMPH!!!" Heather screamed, the panties tasted as bad as they smelled. Before she could spit them out, Kate cleave gagged her with a bandanna and wrapped duct tape around her head, effectively silencing her. 





"There, that will keep you quiet for a bit, my loud mouthed sister." She teased while removing the top of her catsuit, revealing her bare breasts. "While you clean my panties for me, I'm going to get some paperwork done downstairs. Don't worry though, it shouldn't be too long and in the meantime…" Kate pushed a button that activated Heathers dildo vibrators. Heather screamed as Kate closed the door, leaving her with the dirty panties and coming.





As Kate walked downstairs, she ran into Jennifer in the kitchen. "Hey aunt Kate, do you know where mom is. I wanted to talk about some new advancements with the latex suit I made."





"Sorry, she's a bit tied up at the moment." She said grinning. "So where is everyone, I feel like you're the only one here besides me and Heather."





"That's because I am. Dad and David are out on a weekend camping trip, while Jenny is at work with some friends in the archeological department. Didn't mom tell you?" Jennifer chastised.





Kate thought for a moment. "No she didn't, I definitely would have remembered if we had the house to ourselves." She said as a thought came to her. "But now that you mention it, you want to help us play another game?" Jennifer raised an eyebrow, smiling.





About 30 minutes later, Heather and Kate were hogtied and gagged downstairs. Kate made a new bet with her sister, double or nothing, win gets to play with the loser all night long. Heather, who enjoyed the idea of punishing her sister, couldn't say no. Jennifer walked in with the kitchen timer. "Alright, whoever can get free or make the most progress with their ropes will win. And to spice this game up, at the 10 minute mark, I'll add a knife in the room. Good luck." She said as she started the timer.





Instantly, both girls started to roll around, moaning at the tight bondage. "When I'm going to get out of here, I'm going to stuff 3 dirty panties in your mouth and fondle your tits all night. Maybe I'll ask Jennifer for her panties as well." Moaned Kate.



"Once I get free, I'm going to cram your mouth with dirty panties and socks and I'll make you come all night! See how you like it, my gagslut of a sister!" Heather moaned in retaliation.





Jennifer continues to work in the kitchen as the two sisters struggle on the floor, moaning threats at one another. "Well as long as they are busy, I can work on my new latex prototype." She said as she looked at her blueprints for the suit, it was a full latex bodysuit with a mask lense that resembled Spider-Man and a spider like logo on the chest. "I finally get to put my secret comic nerdiness to use." She told herself. Unlike her sister, she read a bunch of comics and bought some new ones at the local comic shop. She mostly reads spider-man, as well as some other Marvel and DC titles.





She passed the groaning sister's as she went to the basement, "Since I'll be working in the basement, I'm going to give you the knife early, have fun." She said as she placed a pocket knife on the coffee table. Both girls looked at eachother and began to inchworm towards the table, both eager to win and have fun with the other.







Meanwhile…





A phone rang. "Hello, what can I help you with?" A woman's voice asked. The voice at the other end of the phone talked to her in a hush voice. "Of course I can add you in. Anything for my favorite client, just send me the details and we'll take care of them." She said as she hung up the phone. She then pulled out her cell phone and began to text. "Hey, get to the meeting room asap. Got new job."





The woman walked in a Japanese styled meditation room. She had a curvy frame with G cups and black hair in a bun. She wore a black kunoichi outfit that looked like a swimsuit, she also had a red scarf that covered her face. As she sat down, 2 other girls walked in. One had purple hair with a ponytail, she was dressed in a black uniform that had a V-top, revealing her cleavage. The third had loose blonde hair, wearing a bikini outfit with a mask.





"This had better be good, I was having fun with our newly acquired toys." The blonde said.



"Don't worry Yoko," the purple haired one said. "I'm sure she has a new job well worth our time."



"Indeed I do Shi. I just received our next target." She pulled up an image on her phone, it was Heather and Kate.





"Such big breasts." Yoko admired. "They will be fun to play with and break. We will get to play with them right?"





"I'm afraid we have a deadline. They want it done by the end of the week, that's 3 days from now. But if we get them early, then we can do whatever we want to them." The leader said, making Yoko smile.





"There's no address in the briefing file, how are we going to aquire them sensei?" Shi asked.





"Don't worry, our clients will contact us with details on how to capture them. Until then, make sure you practice your techniques. These are well trained agents, and I want us prepared for anything." The leader said as she walked out of the room.





The Shibari Sisters will strike soon...
