Saturday morning.

I awoke to the exquisite feel of soft, gentle lips on my penis.  I smiled and groaned contentedly, not opening my eyes.  Just feeling.  Enjoying.  Whoever it was, it was just her lips... and they felt exquisite.  Mary, I wondered?  Or Carol?  That thought brought back to mind yesterday's events... and the bitterness I felt.  Not for what had happened, but for how it had happened.  For how Carol had made my Mary her own.

With a contented groan I opened my eyes and smiled down at... Mary.  She looked so sexual, so submissive kneeling there between my legs, her lips wrapped around my stiffening cock, her eyes wide and fixed on mine.  She smiled around my cock when she saw me looking at her.  I felt a flood of excitement.  Mary had her hands clasped submissively behind her back... no doubt something Carol had taught her.

"Good morning, little brother."

I groaned.  "Oh God, Mary... don't stop!"

Mary giggled and put her mouth back on my cock.  I gasped as her lips slipped over my swollen glans.  She watched me intently as she slowly, teasingly took me into her warm mouth and began sucking.

A moment later she stopped again.

"Did you sleep well?" she asked with  a smile.

I groaned.  She was teasing me, damn it.  "Like a log," I smiled.

"Yes, I can tell," Mary laughed.  She nipped teasingly at my stiff erection.  "A beautiful, lovely log..."  She took me into her mouth again, only this time she nibbled my shaft ever so gently with her teeth.  I stiffened and gasped.

"Oh God..."

She fellated me leisurely, not hurrying, just sucking and licking and nibbling for the longest time.  She looked impossibly beautiful, her soft blonde hair almost shimmering, her eyes wide and filled with love as she watched me intently.  As the morning sunlight crept across the bedroom she sucked harder, her eyes locked on mine, her lips sliding oh-so-deliciously on my shaft.  And then my stomach growled.

Mary giggled and slipped her mouth off my cock.  "Hungry?"

"Starving!" I laughed.  I hadn't realized before how hungry I was.  "What time is it, anyway?

"Almost noon."

Noon!?  I couldn't remember the last time I had slept so late.  Yesterday's activities must have taken more out of me than I realized.  Which brought another thought to mind: Carol.

I felt a pang of bitterness.  As much as I had enjoyed yesterday, seeing what Carol had done to my sister – how she had taken such control of her – had stirred inside me bitterness and jealousy.  It was strange, feeling such lust for Carol and yet at the same time such resentment.  I had always thought that what Mary and I had shared growing up was special – and I knew it was – but seeing her with Carol, seeing her do all those things for Carol...

"Where is she?" I asked softly.

"Downstairs," Mary said as she absentmindedly stoked my chest.

"So... we have a little time to ourselves?" I asked hopefully.

Mary smiled.  "A little, I suppose."

A little was all I would need, as horny as I was!  I coaxed Mary up to lie beside me and kissed her gently as I reached for the hem of her nightie.

"Brian, wait."

I smiled.  Mary was blushing now... playing timid.  And I felt like a wolf.  I coaxed the hem of her satin nightie up and...

...and stopped.  A strange leather belt was fastened around Mary's waist, the leather panel front of which dipped down between her legs and concealed her pussy.  It looked like a very sturdy pair of leather panties, complete with little padlocks on the sides.

"Mary, what's that?"

My sister blushed and pursed her lips.  "It's... it's my chastity belt, Brian."

I stared at her.  "Your what!?"

Mary's voice was almost a whisper.  "Carol makes me wear it when... well, when she doesn't trust me to abstain from sex..."

My heart sank with disappointment.  And at the same time I felt a surge of bitter resentment at Carol, that she should have locked my sister up like this.  I examined Mary's predicament with dismay.  The triangle shaped leather panel at her crotch was deceivingly small, but it completely covered her pussy.  There was a narrow slit in the leather, just wide enough, I imagined, for her to pee through but not so wide that I would actually be able to penetrate her with even so much as a finger.  I tugged at the leather contraption, but it was fastened snuggly in place.  I tried to slip my fingers underneath, but it was too tight.

"I've already tried that," Mary said softly.  "Many times."

Well, even if I couldn't take my own pleasure, perhaps I could give Mary hers.  I put my hand on the front panel of the chastity belt and began rubbing it around gently, putting pressure where I knew her clit to be.

"It's no good, Brian," my sister said wistfully.  "It's... it's shaped just so... cupped, sort of, so it doesn't touch me... you know, there."

I eased my rubbing.  "You won't be able to cum?"

Mary smiled.  "No.  And I've tried... believe me.  So many times!"

I moved up and lay beside my sister, resting my hand on her belly.  "I hate her."

"Me too!" Mary giggled.  "At least at the moment."

"Isn't it frustrating?"

Mary laughed.  "Frustrating?  You don't know the half of it!"  She was quiet for a moment, her smile giving way to a serious, wistful look.  "You can't imagine how much I want you right now, Brian," she told me softly.  "How much I need you..."

I didn't have to imagine.  I knew.  Because I needed her too.  I stroked her cheek gently.  "Why do you let her, Mary?  Why do you let her do this to you?"

Mary blushed.  "I... I let her do lots of things, Brian."

I was beginning to see that.  We lay together for a long time, not talking, just lying together and stroking and touching.  "Where does she keep the key?" I asked softly.

Mary laughed.  "If I knew that, Brian, we'd be fucking right now!  For the third time!"

I traced circles around her left nipple though the sheer nightie.  "Maybe we could torture it out of her," I suggested.

"Yeah, right," Mary giggled.  "I'd like to see that."

I would too, more than I let on.  I really was bitter at Carol... twice as bitter now than before, now that I was so horny... and so denied.

"When is she going to let you out of it?" I asked.

Mary shrugged.  "Probably after you go home.  She said last night was a special treat for you."

I groaned.  "Oh God, Mary... I have to have you again!"

"Well, you can't!" Mary giggled.  She watched me a moment, her smile fading.  "Besides, you'd probably rather have her anyway."

I propped myself up on my elbow and gazed down at my sister.  "Why would you say that?"

Mary blushed.  "Come on, Brian.  I saw how much fun you had last night.  How much you enjoyed what she did.  I know she's so much prettier than me.  And her breasts--"

I leaned down and kissed my sister gently on her lips.  "She doesn't hold a candle to you, Mary," I told her softly.  "I'd give up a hundred fucks with her – a thousand... ten thousand, even – just for one chance to make love with you."

Mary blushed in the morning sunlight.  "Well, you're sweet to say so anyway."

"No, I'm serious Mary.  You're the sexiest, most beautiful woman I've ever met."

"What about Carol?"

I slipped my arms around my sister, drawing her close.  "You're ten times more beautiful than Carol," I told her softly, truthfully.  "And so much sexier."  I kissed her gently.  As I gazed into her eyes I felt my smile fade.  "But now Carol has you."

Mary nodded slowly.  "Yes, she has my body," she told me quietly.  "But you have my heart, Brian.  You're my brother, and you were my first."  She blushed lightly as she said it.  "And my best.  You'll always be special to me, Brian.  More than anyone."

I was quiet for a long moment.  "She doesn't have to, you know," I said quietly.

Mary frowned.  "She doesn't have to what?"

"Have your body," I teased quietly.  "I could take you back.  I could re-claim you for my own wicked pleasures."

Mary smiled.  "I'd like that, Brian," she said softly.  "A lot."

I kissed her gently, stealing her into my arms.  I liked the idea too.  But first we'd have to do something about her chastity belt...

*    *    *

While Mary lounged about lazily in bed I went in search of Carol.  I really was horny.  Waking to my sister's lips had brought me to the edge and now I needed satisfaction, both of my more pressing need and also of my bitterness.  I had done everything Carol had asked last night, and more.  And now she locked my sister up, so we couldn't be together?  I frowned.  That bitch.  I would find her and demand that she relinquish the key to my sister's chastity belt to me... and I wouldn't take "no" for an answer. 

I found Carol downstairs in the kitchen, standing at the counter with her back to me.  She was making a salad, the trappings of which were laid out on the counter: lettuce, a tomato, even a cucumber, which brought back to mind our escapades in the kitchen yesterday.  I paused in the doorway, my cock stiffening at the sight of Carol, my bitterness momentarily forgotten.  She wore a flowery white top and an exquisitely tight pink skirt that came just barely to mid-thigh.  Below that her legs were bare -- not even stockings -- and to top it off she was barefoot.  She looked so sexy, her backside so inviting, that I couldn't help but lust for her.  I stood watching her until she turned around and smiled at me.

"Well good morning, sleepy head!" Carol giggled.  "Did you and your sister sleep well?"

My bitterness swelled again, despite my lust.  "What's with that belt!?" I demanded.

"What belt?" Carol asked innocently.

"That one you put on Mary!"

"Oh, that one.  That's just to help her."

"How on earth does it help her!?"

Carol smiled.  "Because, Brian, if I didn't put that belt on her, you two might have been tempted to do something you're not supposed to.  And I'd hate to have to punish her again so soon after yesterday."  She came over and stood before me tantalizingly close, smiling at me so sweetly.  "Were you tempted, Brian?"

I didn't say anything, only glared at her.  The bitch.  She knew I was.  How could I not be?

"I thought so," Carol laughed.  "Besides, you're not exactly discreet about it."  I wasn't quite sure what she meant until she reached down and gripped my penis.  I was still erect, both from Mary's sucking earlier and from my lust at seeing Carol.  Now Carol began milking me slowly, gently, her slender fingers feeling sooo luxurious as she stroked my erection.

"Did my little Mary suck you?" Carol asked with a sly smile.

I pursed my lips but didn't answer.  I wanted to challenge her notion that Mary was "hers", but her fingers felt so damn good.

"You don't have to tell me," Carol chuckled.  "I know she did."  She squeezed my cock tighter.  "But she didn't finish you off, did she Brian?"

"No," I admitted quietly, reluctantly.  Now I wished I'd let Mary finish.  Oh God, if only Carol would stroke me a little faster, a little harder.  But she didn't, and a moment later she took her hand off me completely.

"Good.  Because my pets remain naked and chaste while in my house, Brian.  I'd hate to have to get a chastity belt for you too, so I suggest you learn to live by the same rules as your sister.  That means no clothes, and definitely no messy little orgasms... at least without my permission.  If you're good then maybe -- just maybe -- I'll let you have one more before the weekend's over.  Maybe even with your sister.  Do you think you can remember that, Brian?"

I nodded.  I wouldn't like it, but I would remember it.  Anything for another chance to be with Mary.

Carol frowned.  "I couldn't hear you, Brian.  Can you remember that?"

Oh.  "Yes ma'am," I answered softly, recalling resentfully how she'd instructed me to respond yesterday.

Carol smiled.  "That's better.  You're going to be an obedient little boy for me, aren't you Brian?  You're going to do anything I ask..."

I gritted my teeth.  Yesterday such a suggestion would have had me stiff with excitement.  It still did, even now, but now it was accompanied by a flush of jealousy and bitterness.  "Yes, ma'am."

Carol pressed up against me, her large, soft breasts flattening against my chest.  She moved to kiss me, but when I started to meet her kiss she pulled her head back teasingly.  "Because you'll do anything for another chance to be with your sweet sister... right, Brian?"

The bitch.  She was teasing me!  I nodded and tried to kiss her -- she was so damn close! -- but again she took her lips away from mine at the last second.

"I'll bet you're hungry, aren't you Brian?"

I nodded.  I was very hungry.  I hadn't slept this late in a long, long time, and yesterday's activities had left me with quite an appetite.

"Well, I have something I bet you'll like."  And with that Carol coaxed me down to my knees, right there on the kitchen floor.  With a smile she pulled the hem of her pink skirt up, revealing a pair of white lace panties that were so tight that they clearly showed the bulge of her shaven labia.  Before I could protest that this wasn't quite the type of "hungry" I had meant, Carol put her hands on the back of my head and guided my face between her legs, pressing my lips to the crotch of her panties.

"There you go, Brian," she giggled.  "Eat to your little heart's delight!"

"Mmmph!"  I tried to pull back but Carol held me tight.  Her taste was strong, even through her panties.  My stiffness swelled.  I put my hands on Carol's thighs, but instead of pushing her away I pulled her tighter to my face.

"Oh!  That's nice Brian, just like that!"

I nibbled her through her panties, licked her, sucked her.  My bitterness was momentarily forgotten, replaced by my arousal and desire to have her, even if only with my lips.  But it wasn't enough just to suck her through her panties.  I wanted my lips and tongue on her cunt, without anything in the way.  I reached for her panties, to pull them aside, but Carol giggled and batted my hands away.

"Oh no you don't!  That's only for good little slaves who have earned it."

I groaned and tried again.  This time Carol captured my wrists and tried to push me away, laughing.  "Okay, that's enough.  If you're not going to listen, then breakfast is over."

But I wasn't to be denied.  She'd given me a taste, and now I wanted more, damn it!  It wasn't fair for her to let me go this far and then stop me!  But when I pressed my lips to her panties again Carol pulled me back by my hair.  "I said that's enough, Brian!"  I came away from her pussy with a reluctant groan and she giggled.  "Besides, there'll be plenty of time later for you to worship my pussy.  You and your sister both."

That bitch!  She was teasing me!  But even as biter as I was at Carol, the thought of worshipping her pussy sounded good... though I'd rather it be my sister's, of course, and I'd rather it be with my cock instead of my lips.

"In fact, why don't we go upstairs and find your sister right now," Carol suggested.  "I'll bet she's as hungry as you."  And with that she coaxed me to rise.  She took my cock in hand again, squeezing me tightly, and then used my erection as a sort of leash to lead me toward the stairs.

"And don't you dare go soft on me, Brian.  That's a new rule, just for you: my male slaves are always to be erect when they're around me..."
