Under Lock and Key

Without a word, Megan walked up to her and gently pushed her onto the bed. She pinned her arms above her head and gazed into her eyes as she knelt down on top of her, Amy's thighs held prisoner between her own.

"You'll have to earn your freedom," Megan informed her, "regardless of how long it'll last this time."

_This time?_ thought Amy. How many times did she think there would be? How long could she possibly keep this up? The thought of being Megan's slave for even longer should have scared her, but it only made her even more wet. She forced her head up to kiss Megan, but it was instantly pushed back down onto the pillow by the force of Megan's desire as she plunged her tongue into Amy's mouth, forcefully exploring her.

Megan let go of Amy's arms, still kneeling on top of her. Amy sat upright, wondering if Megan was really going to go ahead with this after all. Before she knew what had happened, Megan had slid her arms behind her and unfastened her bra, throwing it onto the floor. It was still only the second time Amy had been exposed to Megan in a sexual context, and she reflexively folded her arms over her breasts.

"Don't be ashamed," encouraged Megan. "You look good. You look..." She searched for the right word, and her eyes visibly lit up as she said "inviting."

Before Amy could object, Megan slid her hands up to cover her breasts and gently squeezed them. It was the first sexual contact Amy had received in months, and she couldn't help letting out a whimper.

Megan continued groping Amy's breasts as she started to flick her tongue against one of her nipples. Shocked by the sudden burst of pleasure, Amy let out an approving moan, which intensified as Megan eagerly sucked at her areola. Without even thinking, she undid Megan's jeans and slid her hand inside, pressing gently on the briefs encasing her labia.

Megan stopped fondling Amy for just long enough to take her own top and bra off while Amy pulled her jeans down. Amy gently caressed her inner thigh, slowly moving her hand up and down her smooth skin, sliding everso slightly closer to her briefs each time. Before long, she was gently sliding her hand along the outline of Megan's labia. She looked up at her for a reaction, pleasantly surprised to find an expression approximating a mixture of happiness and excitement on her face.

Amy tentatively drew her hands to Megan's hips before tugging at her underwear. Megan shifted position to let her drag them all the way down her legs before throwing them behind her. Amy was a little surprised to find her lightly trimmed. Somehow, Megan never struck her as the trimming type. She couldn't help but wonder if she'd only done it after seeing her naked the previous night.

Amy felt her heart race and her breath quicken as she carefully slid her finger into Megan, causing her to gasp. Megan shifted her position again, spreading her legs, and Amy slowly slid her finger in and out of her, building up a steady rhythm.

"Yes," whispered Megan as Amy gradually increased her speed. It was her turn to moan approvingly. As the moans turned into loud, enthusiastic gasps, Amy could tell she was on the brink of orgasm.

"Stop!" ordered Megan suddenly. Amy quickly withdrew, licking her finger as she looked up at Megan to see what was wrong. "Lick me out like the slut we both know you are," she ordered. Amy swallowed hard, and quickly gave up trying to articulate a protest. She certainly felt like Megan's personal little slut, performing on demand.

Amy edged her way down the bed until her head was between Megan's thighs. Her smell was intoxicating. She carefully prised Megan's labia apart as Megan lowered herself onto her face. Soon, her tongue was lapping away at Megan's clit.

Megan seemed somehow even more confident in her moans now. She forcefully grabbed Amy's head in both her hands. Amy could tell she wasn't going to let go until she came.

The intensity of Megan's moans increased as Amy kept moving between her vagina and clitoris, constantly exploring and caressing. Eventually it was too much and she had an orgasm louder than any Amy had ever heard her have when she was with a guy in her own bedroom. For a second, Amy actually felt proud of herself; confident at something she knew she could do well.

"So," said Megan, sliding her briefs and jeans back up, "what would you most like me to do to you right now?"

"I don't know," said Amy, her voice trailing off. Megan crawled back on the bed, still naked from the waist up, to sit behind her. Amy only managed to turn her head half way around in an attempt to look at her before Megan started groping her breasts from behind. Amy let out an involuntary whimper. She was putty in Megan's hands, and Megan knew it.

"Be honest," said Megan, alternating between caressing Amy's areolae with her index fingers and squeezing her breasts.

"I really can't think of anything offhand, there's so --" Before Amy could finish her sentence, Megan firmly pinched her nipples. She gasped in pain.

"You're holding back," said Megan sternly. "Just say the first thing that pops into your head." She went back to squeezing her.

"Well," stammered Amy, "you know I only really get off of sex if I'm tied or gagged." Melting in Megan's playful hands, she added "or both."

Megan abruptly stopped fondling Amy and got off the bed. "Get out your favourite items," she ordered before putting her bra back on. Amy scrambled off the bed, pulled out the cardboard box from the wardrobe and started rummaging around. By the time Megan had got her spaghetti top back on, Amy was eagerly awaiting her. She was kneeling on the bed, still in her boots and hold-up stockings. In front of her were a head harness and a single sleeve.

"What are these?" asked Megan.

"This is the head harness you were looking at earlier. It's a ball gag held in place by these straps that lock around my head using three little padlocks," explained Amy as she pointed to the first item. "It stops me from being able to talk," she clarified. Picking up the second, she said "this is a single sleeve. You can use it to force someone's arms behind them, so they can't touch anything."

"You mean _your_ arms," corrected Megan.

Amy felt her heart miss a beat. All her sexual fantasies were about being dominated, and it was finally happening again. "_My_ arms," she agreed. "It also makes my breasts stick out more with the forced posture, and this D-ring --" She held up the metal ring at the end of the sleeve. "-- can be used to tether me to anything, like a chain connected to a hook in the floor or wall."

"See?" said Megan. "You can think of what you want me to do to you, after all."

Amy cast her eyes down at the bed, realising just how open she had suddenly become.

"You can't use that, though," said Megan. "You'll need your hands relatively free. Put it back."

"How free?" asked Amy as she put the single sleeve back in the box.

"Enough to masturbate, should you choose to do so," replied Megan, smiling.

For the first time, it occurred to Amy that if she caved in, Megan would see her masturbating. She just knew that Megan wouldn't be repulsed by the sight. Hell, she would probably even enjoy it. Feeling superior for not being as horny all the goddamn time. For Amy, it would be more embarrassing than she could bear to contemplate. She knew that in all honesty, Megan didn't love her. It wouldn't be like a lover fondly gazing at her so much as someone observing her with a clinical curiosity.

Amy pulled out a pair of lockable wrist cuffs, held together by a short yet very sturdy looking chain. "I can only just about grope and finger myself with my hands tied behind my back with these," she said, offering it to Megan.

Megan grinned. "Perfect."

Amy looked up nervously at Megan, who simply smiled back down at her. Megan swung the five keys around her finger. "Don't move, I'll be right back," she said as she left Amy's bedroom. Amy had, on her order, strapped the head harness on herself, then padlocked all three straps of it firmly shut on her insistence. Megan had then tied her hands behind her back and locked both cuffs securely shut.

Checking her secure bonds in Megan's absence, Amy was still feeling a wave of conflicting emotions. How had one night spent drinking with her roommate escalated into this? More importantly - and the thought made her shiver, but she wasn't sure whether it was with fear or excitement - how far would this go?

Megan returned, wearing a single key on a necklace. Amy guessed which key it was immediately.

"Let's see how much of a helpless slut you really are," said Megan, excitement shining in her eyes. "Get on the bed, my little slave."

_Slave!_ That word alone, when used to refer to her, made Amy's labia tingle.

Megan got behind Amy again, fully clothed this time, her legs stretched out either side of her. Amy let out a long, approving moan of satisfaction as Megan started to play with her breasts again.

"You _really_ like me doing this to you, don't you, slut?" asked Megan as she stroked and teased Amy's areolae.

Amy let out a nervous whimper while nodding. She would have done just about anything for the first sexual contact she'd had with anyone in months to continue.

"Do you want me to go further?" asked Megan. Almost reflexively, Amy nodded again while moaning enthusiastically.

Megan got off the bed and motioned for Amy to stand up beside her. "Come on, up you get," she ordered while reaching for the key around her neck. She didn't take the necklace off; instead, she knelt down to face Amy's gleaming prison. She carefully slid the key into the lock, opening the device before sliding it off her and carefully placing it on top of the bedside table. Turning around to face Amy again, she looked her up and down, taking in the sight. Amy wondered what she saw in her. _Did she really look that cute?_

"Now I've given you your body back, you should put it to good use," suggested Megan. "Take off those clothes," she ordered before starting to rummage around in Amy's lingerie drawer. Moments later, she threw a garter belt and a pair of stockings on the bed. Amy had managed to slip off her boots and hold-up stockings as instructed despite her hands being tied behind her back, but Megan decided it would be easier - and more fun - to dress her up herself. She hugged Amy's waist to put the garter belt on her, and unravelled the stockings up her legs one at a time, gently caressing her thighs as she clipped them in place.

"Kneel down on the bed and spread your legs apart," she ordered. Wide-eyed with excitement, Amy obeyed her.

When Megan got behind her this time, she had full access to her. She started to grope her as she had done before, but before long, one of her hands had started wandering slowly down her body.

Megan started to everso gently caress Amy's labia, finally exposed and glistening wet inside. Letting out another nervous whimper, Amy pressed her groin forwards into Megan's fingers, trying to make the contact more than just a faint touch.

"Uh-uh, sweetie," warned Megan in a voice somehow still playful yet resolutely firm. "You'll have to do that to yourself, and you know the price."

Amy did know the consequences, but she couldn't hold out much longer. With every passing second that Megan groped, caressed and teased her, she grew everso slightly closer to giving in. She wondered just how long Megan could keep it up for.

Then something changed. In a fleeting moment of clarity, Amy realised she'd had enough of Megan's evil mind games. She tried to escape from her embrace.

"What do you think you're trying to do?" asked Megan sternly. "I've already hidden the keys to your gag and wrist cuffs. You're not going anywhere until I've finished with you." Her voice was devoid of its previous playful tone. She pinched Amy's nipples, harder than before. This time she was serious. Amy shouted out a muffled yelp from the pain.

It was too much for Amy to take. Megan was dominating her in the kind of way she'd always fantasised about. Even if her intentions weren't pure or even romantic, it was exactly what she craved. She moved her hand down her back, between her thighs, and plunged her finger deep into her cunt, covering it completely with slick precum. Finally, she would be able to orgasm. She didn't even mind the consequences. She was even looking forward to it, growing closer to being someone's real slave again. Sliding her finger in and out of her glistening cunt, she accepted her fate.
