A Revealing Confinement

Cumming is great, but it can get tiring. So i decided to take a nap while still trapped in my barren room. When i woke up, I found myself no longer in my room, but in the living room, with my arms and head atop what may have been a tabletop, and the rest of my body feeling like it was dangling midair. i looked down to discover that my head and arms were atop, in fact, a glass pane with a hole where my body was inserted. I looked up and came nose to nose with the ceiling. "Ah, you finally woke up." a voice below me said. I looked down to see my perverted brother Andrew, who was apparently holding some kind of metal pole with a handcuff on both ends. "Get me down AT ONCE!" i screamed at him. "Ah, that's for mum to decide. I'm just here to install your spreader bar." Spreader bar? I felt Andrew's hands on my ankles, pulling them apart, so i desperately tried to shut them, but he was too strong. He opened my legs with ease, and latched the handcuffs to my ankles, keeping my legs widespread, while i was hanging from the ceiling, making it so that anyone in the room could easily see my pussy, and if they wanted t touch it, i couldn't stop them. My mind went blind with panic and embarrassment for about an hour, and when i finally calmed down, i found a very big problem - i had to pee. My sister happened to be in the room and i reluctantly told her that i had to pee. She grinned an evil grin and said "Oh sis, i'll help you" and i instantly regretted my choice. She reached behind me and retrieved a plastic tube, which she proceeded to insert inside of me, spending much more time than needed feeling me up. I peed, and then my sister pressed a small button attached to my glass pane barrier. She quickly pulled out the tube and an instant later, a machine apparently attached to my barrier shoves a dildo inside me. "We installed that so you can sit down. As you see, it's not your average chair, and if you do decide to go against our wishes, there are some extra functions this 'chair' has. how about i show you one now!" She clicked a button behind me, and the dildo started thrusting and vibrating.
