"Keys. Ten minutes?" Jake called, poking his head into his sister's room.
Elena nodded briefly, barely looking up from her phone. She waited until Jake had left before smiling from behind a wall of blonde hair, pleased that she was already dressed provocatively in her hip hugging pencil skirt. She touched the soft grey pattern material that enclosed her fit body and pictured how she might find her brother.
Elena spent the next ten minutes brushing her long blonde hair, applying discrete make up and slipping on black heels to further extenuate her height. She was now in the mood as she crossed the hallway into her brother's room.

Elena and Jake were both in their early twenties, Elena three years older than her brother. They lived together in the house they had inherited from their parents, neither of them having found a better option. They had been close growing up and like many siblings had enjoyed playing games. The attraction of tie up games, in particular, had grown with age.
The 'keys' game was a regular occurrence. One of them would use bike locks, chains and handcuffs to secure themselves, but like all self-bondage, that was easily escapable. Then the other sibling would arrive under the pretence of being a cop or prison guard and take the keys. There would be some teasing and tickling, but also time alone to enjoy the feeling of both power and subservience.
As expected, Elena found her brother lying on the floor wearing only grey cotton shorts. He had locked a chain around his ankles which in turn was locked to handcuffs behind his back. As always, every lock still had its key waiting for his big sister to arrive.
"Hog chained?" Elena observed, deliberately showing little emotion. This was supposed to be his treat.
"Yeah, quite tight." Jake's body contorted to accommodate the short chains.
"Even tighter without the keys..."
As she had done many times before, Elena sat on the floor, pulled each key from its lock and dropped them clinking into a pile between her legs.
"Thanks sis, I'll let you know when I want them back," Jake smiled.
Elena discretely shuffled closer; now sitting crossed legged by her brother's head, "Why don't I decide how long?" she replied, the smell of wine on her breathe.
"You?" Jake looked up, surprised by how close she was sitting, the dramatic spikes of her stilettos almost touching his face.
Slowly, she unfurled her long legs which ran down either side of her brother's head.
"El?" he stuttered confused. His sister and the keys would normally be back in her room by now, surrounded by pink sheets and lost in YouTube.
"What's restraining your head?" she breathed.
"These chains not enough?"
She watched as her brother rolled on to his front to hide his obvious erection. He was now like a stranded turtle and she happily exploited his predicament by slowly bringing her thighs together, trapping his head like a vice.
"El? What are you doing?"
Trembling with goose bumps, she shuffled forward until her brother's head slowly edged inside her pencil skirt. "Ellie?" he stuttered nervously as her scent became stronger. He tried to look up, but her skirt wouldn't accommodate, instead pulling him more closely into her thighs.
His head was now completely inside his sister's skirt, his face jammed hard against the inside of her soft thigh. It was a tight fit even before she crossed her legs.
"See if you can escape now," she breathed, her voice wobbling.
Elena had always been in charge. The older sister, an alpha girl, Jake had always been under her command. She could no longer control him physically, but her aura was still there and her desire to keep him as a doting brother even stronger. She may have had her brother wedged into her crotch, but in her mind, it was a game of cops and robbers and her prisoner was simply shut inside his cell.
"El?" Jake called, struggling against his chains. Fuck, he was hard and his arousal growing. He had to get out of his sister's skirt before he climaxed, but his struggles were only adding to his arousal and his sister's thighs were getting tighter.
He stopped and tried not to think of his sister's body, but that was impossible, it had been too intertwined with his puberty. He craned his head back to break the seal that his mouth had formed with her thighs, but his lips were now touching her underwear. 'Fuck', he was now too close and powerless to stop himself crying out as he came.
"Jake?" she called.
She could feel her mounting arousal as her brother struggled on the floor beneath her. His face brushing teasingly against her skin, the heat of his breathe fanning the fire inside her skirt. She had always loved his strong touch of his hands, but the feel of his lips on her thighs was something she had only dreamt about.
"I just wanted to make it harder for you to escape," she lied, trying to hide the fact that she was trembling, "Didn't think you'd do that!"
"I'm sorry El, just let me out."
"Yes, I think I should."
Her thighs were now tacky from perspiration and arousal, making it even harder for Jake's head to pull out of the tight confines. He looked up awkwardly as Elena stood above him.
"Unlock the chains as well," he stuttered.
Elena bobbed down to pick up the loose keys, "No way tiger! I need to control you."
"What?" Jake gasped; their games had always been consensual.
"You just orgasmed in my skirt sweetie."
"Maybe you shouldn't hold the keys."
"Fine, I won't," Elena stood up and placed the keys out of reach on a high shelf.
"Fuck El, I can't get out of here!" he panted.
Elena bobbed down on her haunches, her legs open as far as skirt would allow. Jake groaned.
"I'll clean you up."
