The basement was quiet and its air sultry. Elena's laptop beeped occasionally, its screen throwing light on Elena's discarded pink jumper and other clothes and shoes that she had left casually lying around.
Her desk chair was still standing on the metal hatch with an imprint still in the leather seat where Elena had sat all afternoon. She may not have been sitting there now, but the hatch beneath it was secured by a bolt that Elena had slid across and locked with a padlock that Elena had squeezed shut between her fingers. There was no sign of the key or any indication that the woman who held it would be returning until morning.
Beneath the hatch, in the small concrete drainage pit, Tom was in almost complete darkness. He lay on his back, his feet casually pushing up against the underside of the steel. It was his first night in the inescapable cell and the helplessness of his situation was playing with his mind.
He knew it would be a long night. Elena had locked him away early in the evening, and he knew that she was going to the beach with friends before starting her research the next day. He had no way to communicate with her as she lay in her bed two stories above him, let alone when sand was sticking to her bikini-clad body as the sun rose the next day.

Upstairs in her bedroom, Elena's sister, Kate, had tossed and turned for a few hours before tiring of her own touch. She kept thinking back to her time locked in the pit with Tom. Her fear had quickly turned to excitement and then arousal, and she was now obsessed with the thought of Tom still locked inside. Impetuous as always, she threw of the sheet, bounced to her feet and ran off in search of her sister's captive.
Dressed only in white satin pyjama top and shorts, Kate bounced from room to room collecting up every key that she could find before slinking bare foot back down to the basement.
"Tom!" she hissed; her bobbing thighs spreading as she crouched surreptitiously on the metal hatch.
"Not this time, Kate," Tom called back, "Your big sis has taken precautions."
"Yeah, I see," she growled, aroused and breathy as she gripped the padlock that secured the hatch.
Kate felt hot from excitement, despite her seductive nightwear doing nothing to stop the slightly cooler night air blowing across her goosebump covered body. She tried each key in turn in the lock and when that didn't work, she jammed a screwdriver into the keyhole, her slim arms shaking in frustration as she tried to force it open.
"Stupid thing. Why won't it open?" the breathy blonde cried.
Defying the self-entitled woman had always had consequences, and the padlock soon had to withstand the force of the head of a hammer as she swung it down in her horny desperation. Kate was incensed and was now kicking anything in sight with her bare feet as she pictured Tom's body and cock inside.
"It won't open!"
"You need the key," Tom called, surreptitiously thrusting his hips as he pictured Kate's pent up body above him.
"I don't have it!" she moaned.
"Neither do I."
"But I want to come in. It was fun earlier and I'm so ready for you!"
Tom sat up, the heavy chain around his neck clattering as he pressed his face against the underside of the hatch, less than an inch below Kate's petulantly stomping feet. He had long since fallen for Elena, but there was still something sexually animalistic about her crazy sister.
"Ellie doesn't want you messing with her research," Tom panted, the pit now feeling hotter and more airless with Kate standing above.
"Yeah, right. So, what will the results show if I fill the keyhole with superglue and sit here and masturbate while it dries hard?"
"Run out of men again?" Tom called.
"Fuck you, lab rat," Kate giggled, enjoying their banter as she now tried to break open the padlock by crushing it beneath her bare feet, "but yeah... and I liked being trapped."
Now standing on the hatch, Kate pulled the waistband of her pyjama shorts, enjoying how the satin drew taut between her cheeks and against her vagina. She spun around to look at herself in the mirror, bunching her blonde hair into different styles as she posed. Finally, and with a new plan and a smug grin on her lips, she danced away, up the stairs and tiptoed into her sister's bedroom.

Once upstairs, Kate slipped into bed and snuggled up to her older sister. It wasn't the first time they had cuddled together, but Kate's wondering hands made Elena's eyes blink open in surprise.
"Katie?"
"Let me play with Tom," Kate begged, "I'll put him back afterwards."
"No!" Elena shouted with big blinking brown eyes, "That's why I had to use a padlock."
"Well just give me the key. Please...I've searched everywhere." Kate whined, manipulatively blinking her big brown eyes, "Or at least lock me in there with him."
Realising that she wasn't going to get any sleep with Kate in this mood, Elena whipped back the covers and paced towards her sister's bedroom. Wearing just a white cotton tee-shirt and her new, secretly bought white silk underwear, Elena strode into her sister's pink painted room and picked up the handcuffs that always hung from Kate's steel framed bed.
"Ooh! Are you going to lock me in my own cuffs?" Kate teased.
"Well yes I am!"
"Cuff me to Tom, please?" Kate giggled, rolling down on to her bed and smiling seductively like a 1960's sex kitten.
Ellie knelt on the bed, her knees indenting the soft mattress as she climbed on top of her sister and pinned her hands to the bed. She had once let Kate handcuff her to the same metal headboard and she had stayed that way for hours until their mother had returned and unlocked her. This was payback.
Elena was gripping tightly with her thighs, but Kate wasn't resisting, instead she was grinning as she strained her neck to kiss Elena's knee. Years of sisterly rivalry made Elena determine to seize this victory and she edged her knees further up the bed to pin her sister in place, while sending Kate's kisses further up her inner thigh.
"You smell nice," Kate whispered, her nose tickling her sister's soft skin.
Elena looked down in surprise. If only her little sister had always been this easy to control.
"You're cool," Kate continued with breathy, almost silent red lip as she lay panting beneath her on the bed.
Elena glowed at the unaccustomed compliment. Her body was tingling, and she mischievously edged closer to give her sister's lips full run of her warm curves. She then playful opened and closed her thighs as if playing peek-a-boo.
"Are you really going to lock me in my own cuffs?" Kate purred; her hands already stretching through the bars of her metal headboard, waiting patiently for the one-way steel ratchets to clinch down on her skin.
Elena was confused. This had only started out as a way to get Kate out of her room, but it had morphed into a strangely intimate and seductive moment, and Kate cried out in delight as Elena squeezed the cuffs shut.
"Wow! I can't do anything," Kate breathed, thrusting her hips and rattling her cuffs.
