It hadn't been a dream; her brother was still between her legs. Her damp thighs had been wrapped around his neck all night and his crushed and distorted face still nestled against the front of her pants. He was asleep, his hands hugging her thighs, as if trying to escape from them had been the last thing he had done before drifting away.
She had orgasmed in her sleep, a wet dream, and she wondered whether her brother had been awake to witness it. Had he watched her come, unable to escape her heightened arousal, or had he slept through it, unknowingly driving his sister to ecstasy.
Elena interlaced her fingers behind her brother's head and ground him gently against her. She was almost there when Jake's eyes cracked open, dreamy and confused. She could not be stopped; she simply crossed her ankles and tightened her grip as she continued to work his beautiful face against her vagina.
"Stay, please," Elena moaned as she came down from her high, her body trembling and her long lashes fluttering. Her big blue eyes closed.
Jake was dazed and confused. Exhausted from long periods of arousal, hot, dehydrated and with barely enough oxygen to breathe. Despite this, he hugged her thighs closer, dreading the moment when his sister let him go. That wouldn't be for a while though, as her breathing slowed and her grip tightened, and she fell back into deep sleep.
Jake reached for the towel that he had hidden by the side of the bed and wrapped it around his cock. With one hand on the towel and the other tracing the shape of his sister's bottom, he ejaculated for the fifth time that night.

When Jake next opened his eyes, he was alone in his sister's bed. Elena was sitting on the large wooden trunk wearing a white lace nightdress that plunged more than elegantly between her breasts. She sat with her legs crossed, watching her naked brother slowly awake.
"Do you remember when I used to put you in his trunk," she smiled playfully.
"Yes..." Jake croaked, sitting up and covering his embarrassingly hard cock with her sheet, "I remember all too well."
"Did you like it?"
Jake had never thought of it like that before. He pulled off the sheet and knelt down by his sister's feet. She had often trapped him in the trunk when he'd misbehaved, but thinking back now, it had really been only when he hadn't obeyed her.
Now close enough to smell her perfume, he reached up and tried to lift the lid that as always was held firmly closed under his sister's weight. She slowly recrossed her legs, first leaning to one side to reveal her white thong, and then rolling down so that her cheeks settled back on to the wooden lid.
"Fuck, what chance did I have?" Jake breathed, now even more obsessed with his sister's body.
"None at all... want to go back in?"
Elena uncrossed her legs and pulled her brother back between her thighs. She had long since known why she liked to put Jake in the trunk and a few more deep breathes beneath her nightie and Jake would feel the same.
She stood up and lifted the lid. She moaned out loud with pleasure; this was the first time that her brother had willingly climbed inside, but the end result would be the same.
"Its tight now," he breathed, his face barely below the iron rim of the reinforced box.
"I can make you fit..."
She was now a provocatively dressed woman, aroused by her brother's predicament, yet the look in her eyes was strangely familiar as was the fear in her brother's eyes as the lid banged shut. Very little had changed as she weighed down the lid and listened to the pleas from below.
"Can you cum for me?" she called.
Jake's childhood memories were flooding back, but now they made more sense. He touched himself and moaned gently into the underside of the lid. He heard a shuffle above him, and his sister moaned in unison.
"Oh fuck, let me touch your body..." Jake panted, caressing the underside of the lid.
Elena's eyes were dilating.
"Please, let me go down on you!" he cried.
With her vibrator moving silently between her legs, Elena closed her eyes and breathed deeply.
The same feeling of complete helplessly was back, but this time it was pleasant. The image of a bratty older sister sitting on the box was replaced by the thought of a beautiful woman to which he was happy to submit. Slowly and rhythmically, he climaxed and flopped down motionless inside the trunk.
Elena came moments later, warm breath of a contented sigh as she daydreamed about their new relationship.
"Will you tie me up now?" she whispered.

It was an hour later when Jake walked into his sister's room. She was sitting on the floor with her back against her bed and her hands handcuffed behind her back and around the heavy wrought iron bed frame. She was wearing make up as if she was going out, but was she wearing only her white lace nightdress and thong.
"Key?" she mouthed.
Jake trembled as he edged forward and removed the small silver key from the handcuffs. His big sister was now his prisoner, her aroused body on display with parted lips and dilated eyes.
Previously he would have left her to struggle, but the rules of the game had changed, and she was now his to enjoy.
Elena pulled at the cuffs, twisting her body in an attempt to escape. Her breathing was getting slower and deeper as her legs spread further and her hips moved in time with the quiet atmospheric music.
"You okay?" Jake asked innocently.
His sister smiled and nodded and gazed intently into her brother's eyes. Yesterday had been a trap, literally and metaphorically, and Jake had fallen for it. His acceptance of her touch and her body had opened the fantasy floodgates in her mind.
She was buzzing; helplessly chained up, alone with a man. With anyone else this would have terrifying, but with her younger brother, she could be lovingly controlled.
"Maybe I shouldn't have put you in my skirt yesterday," she goaded, her legs spread, longing for his touch, "trapped in your own sister's pants..." She trembled as her brother took the bait.
He ripped off his tee-shirt and pulled off his jeans to reveal his penis pushing to escape his black boxer shorts. Elena cried out and tried again to escape the inescapable cuffs.
"Trapped between my sister's legs all night," he whispered, "... ground into her crotch?"
"Want to know what I dreamt about?"
"I know," he whispered.
Jake was overawed. This must be how his sister was with her lovers; beautiful yet intimidating. He knelt to kiss and massage her feet, unsure of what to do with the rest of her body.
"Well, I'm your prisoner now," she trembled, the cuffs creating red rings around her wrists.
Jake still looked overwhelmed by his sister's hungry eyes.
"Nothing you've ever wanted to do to me?" she smiled with sisterly love.
Despite being handcuffed, she still felt in control. She sat back in hot damp underwear silently hoping that her younger brother would take advantage. He was on his knees and prowling closer to her. She closed her eyes and flicked back her hair to fantasize.
"Sorry... I've always wanted to..." Jake spoke cautiously as he leaned forward and gently kissed his sister's breasts that were only partly covered by white lace. Goosebumps formed on her excited body.
