"Brian!  Take that out of my little Mary's cunt right this second!"

Flushed with embarrassment I slid the cucumber out of my sister's pussy, feeling her shudder in my arms as it slipped free.  Almost immediately Mary began to apologize.

"Carol!" Mary gasped.  "I'm sorry!  I... I can explain!  We were just--"

"Save it, Mary," Carol said sharply.  Her tone was sharp but her lips were curled in an almost amused smile, as if she would have expected nothing less than to find Mary disobeying her.  She came into the kitchen and approached us, ignoring me for the moment and focusing on Mary.  "I'm not interested in your excuses, you disobedient little slut."

Mary shut up as if she'd been struck.  In a way, I suppose she had been struck, if only by Carol's sharp words.

"I thought we had a deal," Carol said.

"We... we did," Mary said softly.  "I'm sorry."

"You will be."  With a smile Carol took hold of my sister's hair and pulled her head back sharply, drawing a surprised cry from her lips.  "I've warned you about this before, haven't I Mary?  About you being disobedient?"

"Ow!  Yes Carol, you have."

"I would have expected this kind of behavior from your brother.  After all, he's just a horny guy.  But I expected you to have more self control.  I trusted you, Mary."

"I know, I'm so sorry."

Carol reached down with her free hand and pressed two fingers into Mary's pussy.  "Remind me whose cunt this is, Mary."

"It's... it's your cunt, Carol," Mary said quietly.  "Please, it's--"

"Did I give you permission to play with 'my' cunt tonight, Mary?"

"No, but--"

"Did I give you permission to let your brother stick a cucumber into 'my' cunt?"

"No," Mary answered softly.  "I'm sorry, I was just--"

"You were weak," Carol declared with an amused smile.

Mary hesitated.  "Yes, I... I was weak.  Please Carol, it's been so long."

"And now it's going to be even longer.  Do you remember what we talked about earlier?  Before your brother came?  About your obedience?"

"You... you said if I was obedient, you might let me... let me fuck my brother tonight."  Mary's voice was soft, almost a whisper.

"And if you weren't obedient?" Carol asked with amusement.

Mary hung her head.  "Then you'd punish me."

"And what have you been?"

"I've been disobedient," Mary admitted reluctantly. 

Carol nodded, then turned to me suddenly.  "And you, Brian.  I should kick you out right now!  What makes you think you can come into my house and take advantage of my sweet little Mary without my permission?" 

"I'm sorry," I stammered, "I--"

"I don't care if she is your sister.  You had no right!"

"I know, I'm sorry."

"Give me one good reason why I shouldn't kick you out right now."

I couldn't think of a single reason for the life of me.  But before Carol could follow through on her veiled threat, Mary begged desperately.

"Please Carol, don't make him go!  I... I'll be good.  I'll do anything you want, just please let Brian stay."

Carol seemed amused by Mary's pleading.  "How about you, Brian?  Are you as eager as your sister to please me?"

"Yes," I assured Carol quietly.  I glanced at Mary but she was avoiding my eyes, her cheeks flushed with embarrassment.  The last thing on earth I wanted right now was to be sent away.  "Please don't send me away."

Carol chuckled.  "Would you like to stay and watch me punish your sister?"

I hesitated, unable to answer.  As arousing as the thought was, I couldn't bring myself to admit that I would in fact love to watch Carol punish my sister.  When I didn't answer, Carol moved close to me, smiling at me with amusement.  Before I knew what was happening she reached down and gripped my erection tightly through my pants.

"I'll take that as a yes," Carol told me with amusement as she squeezed my obviously-hard cock.  I blushed.  Hearing Carol speak so firmly to my sister had been shamefully arousing for me.  Now there was no hiding my arousal as Carol explored me with her fingers.  She gave my stiff penis another squeeze and then let go.

"Okay Mary, I'll let your brother stay.  If you're good and obedient and make me proud, perhaps I'll even consider letting you fuck him despite your disobedience."

"Oh, thank you Carol!" Mary exclaimed with relief.  "I'll be good.  I'll do anything you want!"

"Yes, I know you will," chuckled Carol.  "Now then, how many punishment points do you think you've earned with your little indiscretion?"

Mary was quiet for a moment.  I wondered just what ‘punishment points' were, but I didn't dare ask.  "Twenty," Mary suggested softly.

"Twenty!?" laughed Carol.  "I was thinking more like a hundred."

Mary paled.  "A hundred!?  Please Carol, not so many!"

"Would you like to make it two hundred?"

Mary gasped.  "Please Carol!  I can't take a hundred."

"How many then?"

Mary hesitated.  "How about fifty?"

Carol seemed to consider it a moment.  "Okay, fifty it is.  But you're getting off easy, Mary.  Remember what I did to you when I caught you fucking that man from down the street?"

"Yes, I do," Mary said.  "Thank you, Carol."

Carol smiled.  "I'll be right back.  You two wait here... and no fooling around this time."  Carol turned and disappeared from the kitchen.  I found myself following the tight, sexy sway of her bottom with my gaze and I blushed.

When we were alone I turned to my sister.  "I'm sorry Mary, I shouldn't have gotten you into this."

Mary smiled wryly.  "You didn't get me into anything, Brian.  Besides, it was so nice to feel your lips on me again.  And your fingers..."  She fell quiet, as if remembering.

"What are punishment points?" I asked.

"It's how Carol punishes me," Mary said softly.  "She's assigned point values to the various ‘punishment instruments' we have.  She'll use them on me until she's exhausted the number of points that I've earned.  Now shhh!"

Carol came back into the kitchen just then carrying two objects: a short metal spreader bar with leather straps on each end, and a slender black anal plug.  She handed me the spreader bar.  "Put this on your sister, just above her knees."

Without a word I knelt and did as Carol asked.  I'd never held or even seen a spreader bar before.  It was made out of shiny stainless steel and was about two feet long, with leather straps at each end.  I fitted one of the leather straps around Mary's left leg, just above her knee.  She didn't say anything, and I couldn't bring myself to look up and meet her eyes.  Without having to be told Mary spread her legs so I could position the spreader bar between her knees.  The second strap I fastened to her right leg, buckling it tightly.  Mary was now hobbled just above her knees, unable to close her legs or walk easily.  Together with her wrists being bound behind her back she was a vision of sheer, submissive beauty.  I had never found her so arousing before.

Now Carol held the slender anal plug to my sister's lips.  "Lick this good, Mary.  You know where it's going." 

Mary opened her mouth and reluctantly accepted the plug between her lips.  As she licked and sucked the slender black shaft, lubricating it with her saliva, my cock stiffened.  The look on her face made it clear that she didn't relish the thought of Carol inserting the plug inside her.

After a moment Carol withdrew the plug from Mary's mouth.  Without a word she teased the glistening tip of the shaft over Mary's lips.  "Tell me, Mary... whose mouth is this?"

"It's... it's your mouth, Carol," my sister told her quietly.

Carol smiled and moved the plug down between Mary's legs, teasing her pouting pussy lips with the tip.  She nudged the tip just barely into Mary's pussy, teasing but not penetrating.  "Whose cunt is this, Mary?"

"It's your cunt, Carol."  My sister's voice was almost a whisper and her cheeks were flushed with embarrassment.

Carol moved the plug back further, positioning it at Mary's tighter hole.  "And whose asshole is this, Mary?"

Mary hesitated.  "Please, Carol... you don't need to do this."

"Oh, but I do," Carol said with amusement.  "I know how much you dislike the plug, but you need to learn that your body is not to be penetrated or violated without my permission.  I want you to remember that as I plug you.  Do you understand?"

Mary's voice was barely a whisper.  "Yes Carol, you know I do."

"Good.  Now tell me, Mary... whose asshole is this?"

"It's... it's your asshole."

"And what can I do with 'my' asshole, Mary?"

Mary hesitated for a moment, obviously less than thrilled at what we both knew was coming.  "You... you can do anything you wan--uuhh!"  Mary's voice became a grunt as Carol pressed  the plug firmly into her bottom.  The plug penetrated her easily, sinking in deep on the first push.  I watched incredulously, my eyes wide and my cock stiff.  Mary had never before been interested in having her asshole played with.  Even now she looked like she didn't like having the plug seated so deep inside her bottom.

Carol must have seen my look of amazement because now she smiled and chuckled.  "Don't look so surprised, Brian... your little Mary isn't nearly as innocent as she was the last time you were with her.  She still hates to be penetrated anally, though.  That's why I use this plug as punishment.  It reminds her that I have complete say over who or what penetrates her, and where... doesn't it, Mary?"  My sister nodded reluctantly and Carol smiled.  "She hates to have her bottom violated.  The first time I let a man fuck her asshole she pouted for a week."

I was partly revolted but also excited by the thought of my sister allowing herself to be sodomized.  The mental image of Mary ass up on a bed with a man behind her, taking her where she obviously hated to be taken, made my cock stiffen even more.

I still held the cucumber.  Now Carol took it from me and studied it, encircling it with her fingers as if examining its size.  The thick green shaft still glistened with Mary's juices.  With a smile Carol brought the cucumber up to my sister's lips.

"Lick it, Mary.  Get it ready for your cunt."

Mary moved to take the cucumber into her mouth, but Carol stopped her.

"No, do it slowly Mary.  Make love to it with your mouth.  Pretend it's your brother's cock."

Blushing, my sister extended her tongue and licked up the underside of the cucumber as if it were a penis.  She licked it again and again, despite it being covered with her pussy juices.  After a few licks she took the tip of the cucumber between her lips and sucked it gently.  I could see her nibbling at the tip with her teeth, ever so lightly.  Then slowly she took it into her mouth, inch by inch, sucking and licking as she did.  Halfway into her mouth, then back up and off.  She licked around the tip, nipped at it with her teeth, moved down to lick up the shaft, and then took it into her mouth again.  This time she sucked it in eagerly, taking it nearly all the way to where Carol's fingers encircled the green shaft.  With the majority of the cucumber in her mouth, Mary began bobbing her head and sucking.

"As you can see, Brian, your sister's become much more talented since you were last with her," Carol teased me as she held the cucumber for Mary.  It was true.  All those years ago Mary had been timid and careful the few times that she agreed to suck me.  Now she seemed comfortable and even eager to take the cucumber in deep and make love to it with her mouth.

"She might not get to fuck men very often," continued Carol, "but she gets a lot of practice with her mouth.  It's a shame, really... if you had been more respectful of my property you might have gotten a chance to feel her sweet lips on your cock before the night was out."

I felt a pang of jealousy and remorse.  Jealousy at the thought of Mary performing orally on other men, remorse at having apparently blown my chance to experience Mary's obvious talent at fellatio.  Carol saw the look on my face and laughed.  I was beginning to feel like she was playing with Mary just to arouse and frustrate me.

"That's enough," Carol finally said.  Mary slid her mouth off the cucumber almost reluctantly, as if she had forgotten for a moment that it wasn't a real penis.  Despite her flush of embarrassment I could tell she had enjoyed performing on the vegetable. 

Now Carol lowered the cucumber and guided it between Mary's thighs.  She nudged the thick tip between Mary's pussy lips, and then with a firm push she inserted  the saliva covered vegetable deep into my sister's pussy.

"Oooh," Mary moaned.  Her eyelids fluttered as Carol slowly eased the cucumber in and out of her pussy a couple times.  On the third up-stroke Carol left the cucumber buried deep and let go.

"You'd better keep that in," Carol told my sister with an amused smile.  "If it slips out, I'm doubling your punishment."

Mary whimpered and I could tell she was trying to tighten herself on the cucumber.  But with her legs forced apart by the spreader bar, I knew she would have trouble.  Sure enough as Mary's thighs tensed in vain the cucumber began slipping slowly, almost imperceptibly out of her pussy.

"I'll administer your punishment in the bedroom," Carol told Mary.  "Don't keep us waiting too long... and don't you dare let that cucumber slip out.  Now come along, Brian."

Carol turned and headed for the doorway.  I started to follow and stopped.  Mary was watching me with a helpless look. By the looks of it, the cucumber had slipped out an inch or so.

"Brian, please help me?"  Mary's voice was a hushed whisper.  "It... it's slipping out."  I looked over my shoulder and saw Carol disappear through the doorway, her back to me.  Unwatched for the moment, I quickly reached down and pressed the cucumber back into Mary's pussy.

"Thank you," Mary said quietly.  She took a couple tentative steps, whimpering as the cucumber began to slip out again.  Without being able to press her thighs together and retain the slippery shaft inside her, I knew my sister was going to have trouble avoiding a doubling of her punishment.

"Brian?" called Carol.  "Are you coming?"

"Yes, ma'am," I called back.  The "ma'am" part just slipped out.  I was beginning to think of Carol as my dominant as well as Mary's, if only for the weekend.  With a sympathetic smile to my sister that I hoped conveyed that I was sorry to leave her in such a predicament, I turned and hurried after Carol.

  *    *    *

I followed Carol to their bedroom.  The bedroom appeared entirely normal, until I turned around and saw the pictures on the wall.  There were seven or eight of them, artistic looking black and white photographs of a woman whose face wasn't visible.  I gasped in shock.  The woman was Mary!  Even without seeing her face I knew it was her.  She was in various positions in each of the photos, standing in some, sitting in others, in a couple kneeling in very submissive positions.  In one photo her lips were wrapped around a man's erect penis.  I could tell it was her just by her lips.  I felt a pang of jealousy at seeing her sucking another man and I quickly turned away.

I looked around the room and realized it wasn't quite as normal as I had first thought.  The four poster bed had several steel rings discretely gracing its posts and frame, obviously attachment points for bondage.  A pair of paddles and a riding crop graced the wall in one corner of the room, located so as to not be visible unless one entered the bedroom and looked around.  In another corner of the room sat a strange looking bench, waist high and about three feet long with a padded leather top.  The top of the bench was narrowed toward one end, for a reason I couldn't fathom.  I quickly deduced that what I was looking at was some sort of punishment bench.  This all was far and beyond anything Mary and I had contemplated in the innocent little "tie me up and spank me" games of our youth.  Obviously Mary had matured in more ways than one.

"Would you mind bringing that over here?" Carol asked me, pointing at the punishment bench.

I hesitated, then moved to the bench.  It was heavy and constructed of solid wood.  I supposed that it had to be sturdy, to not collapse under the weight of a person.  Thankfully it had wheels on each of its legs.  But even so it still took quite a bit of effort for me to drag it to the middle of the room where Carol indicated. 

As I straightened up from my task Carol moved intimately close to me.  I could smell her sweet perfume and I realized with a start that it was the same alluring fragrance that Mary used to wear when we fooled around.  Coincidence?

"If you're good," Carol teased me, "maybe I'll let you help me punish your sister."

I didn't say anything, though the idea aroused me.

"And if you're very, very good, maybe I'll even let you fuck her."

"Anything," I stammered hoarsely.  "I'll do anything!"

Carol laughed at my eagerness.  "I know you will, Brian.  Now put your hands on your head."

It was a strange request, but I did as she asked.  As I stood with my hands on my head, watching her breathlessly, Carol moved close and ran her fingers over my chest and down to my belly.  "Mmmm, nice," she commented softly.  I didn't say anything.  She ran her fingers lower and suddenly squeezed my crotch.  I was still hard from watching her chastise Mary earlier.  Carol smiled, as if amused by my arousal.  She squeezed my cock a moment longer and then unzipped my pants and fished my erection out.  As her fingers encircled my stiff, naked cock I caught my breath.  Oh God, if she would just stroke me a little I would be in heaven!

But Carol didn't stroke me at all.  Instead she let go of my erection and stood back, admiring me with amusement as I stood with my stiff cock poking out the front of my trousers.

"You're too hairy," Carol commented, eyeing my bushy pubic hair.  "I like my men shaven smooth... just like my women."

I was about to ask what she meant when Mary came into the bedroom.  She was moving slowly, her steps awkward since she was still hobbled just above the knees with the spreader bar.  I glanced at her and felt my heart sink.  The cucumber was no longer buried in her pussy.

"I... I'm sorry," Mary said softly even before Carol could comment.  "It slipped out.  I couldn't help it."

"Where?" Carol asked simply.

"In the hallway."

"Do you plan on just leaving it there?"

"No, I–"  Mary hesitated.  "I'm sorry, I'll get it."  She turned to go, but Carol stopped her.

"Wait."  Carol went to Mary and untied her wrists.  "Crawl," she told my sister with a smile.  "Bring it to me in your mouth."

Mary slowly dropped to her knees and crawled.  I felt a stab of arousal as I watched her shapely bottom disappear through the doorway.  A few moments later she was back, this time with the cucumber in her mouth.

"I'm doubling your punishment points, of course," Carol said casually as she took the cucumber from Mary's mouth.  "That makes one hundred points that you've earned."

"Thank you," Mary said softly, obediently, though I could tell she wasn't happy in the least about having her punishment doubled.

Carol took the cucumber from Mary's mouth and stroked her hair lovingly for a moment.  Then she turned to me.  "Now, Brian, if you want to remain a guest in our house – and I think you do – I need to know that you will do anything I ask."

"Yes, anything," I offered quickly.

Carol smiled, amused.  "I of course require complete obedience.  Your sister understands this, more or less... though as we've seen tonight she doesn't always do as I would like."

Mary blushed but didn't say anything.

"How about you, Brian?  Will you obey my instructions without question?  Will you do anything I want?"

I nodded.  Right now, I thought I would do anything for Carol.  "Yes," I said softly.

"You'd eat my pussy?"

The thought of being allowed to pleasure Carol orally was incredibly arousing.  "Yes, of course."

"You'd fuck me?"

"Yes!"

Carol laughed at my obvious excitement.  "What if I decide I don't want you to have sex with my sweet little Mary?  Would you obey me and remain chaste while in our bed?"

I hesitated.  I wanted no such thing, but I also knew I had no choice but to agree.  "Yes," I answered quietly.

Carol smiled.  "I wonder if you're serious about that.  Well, perhaps we'll find out later."  I didn't say anything, but I desperately didn't want that to be the case!  Carol continued.  "As you can see, Brian, your sister is shaven bare below her neck.  I like smooth bodies.  Would you be willing to let your sister shave your body for me?"

I had never before considered shaving my body, and I probably wouldn't have now except for the fact that Carol was suggesting my sister do it.  I nodded.

"Wonderful!" declared Carol.  "I think you'll like it, Brian.  I know I will.  Mary, take your brother and shave him in the shower.  Prepare him for our bed.  Understand?"

"Yes," my sister said quietly.

"Make sure you do a good job," Carol added with a smile.  "For each hair that you miss, I'm adding ten points to your punishment.  And be sure that you two stay out of trouble this time.  I would hate to have to double your punishment points again."

Mary gasped, wide eyed at the thought.  As Carol chuckled, Mary quickly took my hand and led me toward the bathroom.
