I awoke the next morning, feeling surprisingly relaxed. I had warm and pleasant dreams about Marisa; the two of us laughing, smiling, running around, playing tag, building snowmen together... All in all a wonderful experience. I yawned and stretched, preparing to greet the day. I moved carefully, expecting to feel pain in my testicles as I rolled to the edge of the bed, but to my surprise it was nowhere near as bad as I anticipated.
I kissed my sister good morning and we had a shower as we prepared for the day. I was a little sad that I couldn't say good morning to my daughter, as she was away at band camp and wasn't permitted electronics, but in a way it was sweet. It made my heart long for her more. In a lot of ways it seemed that modern society was totally neurotic; instantaneous contact with anyone you like always at your fingertips. There was not the same opportunity to pine, to miss, to wonder. The feeling was like something from the days of old, where a letter traveling several weeks might separate lovers. It made me wonder if Marisa was longing for me in the same way. The sensation was delectable.
Another divine thought occurred to me - Karen and I were home, free to express and celebrate our sexuality together as we wished, in private, without fear of discovery. I knew, thanks to my devious sister, that Marisa masturbated thinking of me. Would she attempt that at camp? In a room filled with beds all containing other girls on all sides of her? Would she bring herself to climax quietly, motionlessly, thinking of me?
My dick was getting hard.
Karen noticed. She smirked. Then proceeded to tease me. Oh well, there would be no release for me. Until tonight, for good or for ill.
I thought of Marisa back in her bed last night - was she suffering the same way? Was she too shy to please herself? Lying there, yearning, needing, throbbing... Dying to touch herself, to caress her tingling labia and clitoris, to tease herself, pleasure herself, and bring herself to orgasm, thrusting and grinding against her fingers, sighing softly in lust - but unable to? Was she, like me, denied pleasure and release?
Oh, fuck, now my dick was like steel. Rigid and bobbing in the air. My nuts were starting to tighten uncomfortably - Ok, enough of this. I would see Marisa tomorrow night.
...And she was having that damned sleepover!! Oh hell, the J girls, Julie and Jamie, would be over. A flash of indignant anger swept through me. Partly out of jealousy - I wanted Marisa all to myself. And also partly because they had fed Marisa that Valium. Well, maybe they hadn't fed it to her, but they gave her access to it.
I put the whole thing out of my mind as best I could and got on with my day.
Work was nowhere near as uncomfortable as yesterday. My nuts were still a bit sore, but every time I thought of the ridiculous lengths I had gone through yesterday to obtain relief (without jacking off) I felt a flash of embarrassment and shame. Thank god no one had seen!
Each time my eyes brushed past the picture of Marisa on my desk, I felt a pang of longing, or a surge in my loins, or both. She was so beautiful! And her smile was dazzling! She was truly the apple of my eye. I couldn't wait to get her alone, hold her in my arms, kiss her soft lips, dance my tongue down her neck, between her breasts... Whew! Hard to concentrate on work. At a couple of points I was tempted to put the picture into my desk drawer so I could concentrate, but no way. She was my joy, my inspiration. There was no way I was going to try to symbolically put her out of my mind like that.
I worked, phoned, scanned, emailed and scribbled my way through the day. I was in good shape. One more day of this and I would be ahead of the game enough for a four-day weekend at the lake with my sister and my daughter. Heaven.
I finished up, closed up, and headed down to the parkade, feeling good. Then a cold sweat hit me. I had promised Karen that she could domme me tonight. And she had told me straight up that she was going to be rough on me. Then I thought about why. I had lost the bet that Karen could get Marisa's mouth around my dick. Hell, for that I'd let her domme me for a week straight! I was getting off light.
I drove home, Karen and I greeted each other with a kiss and some groping, and we had dinner out.
It was fairly rare, even now that Marisa was eighteen, that we had a full evening and night to ourselves, so we decided to make a bit of a date out of it.
Dinner was lovely, and Karen and I felt very free and flirty. It definitely seemed like some of the excitement I was developing with Marisa was spilling over into our relationship as well. Everything was wonderful. We refrained from drinking any wine, because we both wanted to be sober for what was to follow, but we both felt buzzed nonetheless.
When we arrived home, there was plenty of kissing, and squeezing, and pawing, and in general bawdy, lusty behaviour. We both wanted each other terribly badly. But games were in store, so I resisted the urge to throw her down to the kitchen floor and fuck her senseless.
We dragged the rubber pad out of storage, put some towels down on top of it, and I assembled the X-frame and attached it to the anchor points which were part of the book case frame. We'd had some time and thought put into this arrangement.
I took a pee to make sure my bladder was empty, as I was sure I wouldn't be free for some time once locked in.
I shed my clothes, and stepped into the X-frame as Karen locked the wrist and ankle cuffs, as well as the belts to hold my chest and hips in place. My heart was beating fast and my cock was at full attention.
Karen laughed as she secured the last lock. "Now I've got you right where I want you, Big Brother!" she cackled. I grinned back in spite of my fear. She looked me deep in the eyes and grasped my cock, stroking it rapidly. "This is what I want," she breathed huskily. "It's right in there. That load. I've been dying for it for the last two days. And now it's gonna be mine. All mine. You can't do a thing about it. You're totally at my mercy, helpless to do anything. Except give me your load. And you will. You will."
I moaned as she jerked me. Was she going to just go for my load right now? I gasped and twisted, and she kept up her pace. She stroked her hand up and down the shaft of my penis, up and down, up and down, as I writhed and struggled for breath, her eyes locked into mine.
I felt my load start to rise. My spine was tingling, my balls contracting and throbbing. Karen grinned and stroked even faster, yanking hard on my dick. I was moaning helplessly in her grasp, getting closer to orgasm, closer, closer...
Then she stopped dead. Releasing my throbbing prick with a laugh, she turned and left me, thrusting and groaning in lust and frustration.
"Not yet, Bro," she teased. "I want to get dressed first. Then I want to play with you for a bit. And then," she paused, coming in so close I could feel her breath on my neck, "I'm going to Suck. You. Dry."
I was panting as my heart pounded in my chest. I had no words. I just stood there, shackled and helpless with my engorged erection throbbing straight out, as my sister turned and strode upstairs, her ass swaying sensuously and deliberately with each step.
I was so turned on I couldn't think. That was probably for the best, because whenever I did, I kept trying to conjure up scenarios of what might be in store for me. No, better to just go with it. I was powerless to influence the situation at this point anyway.
I hung there and waited. My pulse rate was accelerated and my dick was hard as steel. I couldn't wait to blow my load.
Long minutes past as I stood shackled to the X-frame awaiting my little sister's mistreatments. I hoped she would let me cum first, then get up to whatever deviltry she assuredly had in store for me.
My penis was bobbing at half-mast when Karen descended the stairs again. Instantly, my dick roared to full attention when I beheld her visage. She had on black stiletto heels, thigh-high stockings with a garter belt, black lace panties and a black corset that was comprised of lace and faux-leather. She had bright red lipstick on, and her eyes were heavily made up. She looked wickedly divine and wore a facial expression to match.
Oh god! What was I in for?! She ambled towards me wearing a smirk, her hips swaying in exaggerated fashion with each stride.
She reached down and tickled the underside of my penis and chuckled as I shuddered. She lightly ran her finger up and down, gently tracing the bottom of my rigid, throbbing member and grinning at my reaction. A big glob of precum was glistening at the tip of my helmet. My sister flashed me a wicked smile, and knelt down and kissed the tip of my penis.
She looked up at me, her face a mask of dominance, lust, mischief, menace... my cock, already pounding in arousal, surged even harder with desperate need. She withdrew her lips from my dick slowly and deliberately, and a thin streamer of my precum joined us still as she drew back. It broke and swung down, streaking her lower lip and chin in a glistening, thin, clear line.
She then, ever so slowly, bent forward again to kiss the head of my prick. She made contact with my helmet, placing tender, loving kisses directly on the tip. Then she kissed more deeply, sucking gently, taking the precum I had produced into her mouth. She looked up at me again, the flame of possessed lust in her eyes. Slowly, carefully, deliberately, she ran her tongue along her glistening, parted lips, then closed and swallowed.
"Mmmmmm," she purred. "That was soooo delicious, Big Brother... you can't imagine how badly I want to eat up every drop of cum you've got built up in those balls for me... speaking of which, how are they doing?" She giggled at her query.
"They're actually doing ok..." I replied. "There was some... discomfort... but I think I'm over it now. Now they just feel full. Real full. Like I need to blow a load. Like, urgently," I added, chuckling a bit.
