My sister and Suzy were sat out chatting on the balcony, enjoying the sun and the view with cold drinks in hand. I had been cleaning up in the en suite after my humbling as their human toilet. My cock was still engorged as my mind replayed their delightful, disgusting debasement of a mere man.
"Finished sweetie?" My sister offered me a drink and gestured at the spare chair the other side of Suzy.
"Oh gosh, you are fucking hard again!" Suzy couldn't help but notice my tumescence as my cock bobbed and wobbled at her eye level. It wasn't an accident that I slowly shuffled to the seat displaying myself to her. It was always a thrill to be naked in front of people, she was still a fresh face and cunt just today.
But adding to the thrill was that despite we knew, as our friends Carols' daughter, she was 25 she could easily pass for years younger. She was blessed with and had looked after a baby doll face and body so looked more like a uni fresher than our prospective interior designer.
Our mistress mother dominatrix had made her deputy for the tour of the site, our prefect pro tem. To mark our obeisance mum had fitted us both with bondage dog collars, giving Suzy the leashes. As a symbol of her dominion over us, mum had given Suzy a bondage crop, which rested on her lap.
I passed my leash to her and nodded humbly, still under an order of silence that she had not lifted.
"You, we told him not to speak, prefect." My sister reminded her. Suzy's eyes widened and she smiled in delight.
"Ooh yes!" She gave an involuntary shiver. "I can't get used to just how fabulously kinky you people are. This isn't what I expected today, it's so much more, more...pheeeewwww." She just puffed out her cheeks to express the wonderment she couldn't express in words. Her yes flicked between by nodding cock head and low, weighted balls, each testes clear to see under the thin, stretched skin of my veined, smooth shaved scrotum.
"I have never seen a man...a man so clearly, each one so..." She reached forward to brush each index finger over their respective testes, which made me stand upright a little more. Realizing she didn't need to stretch, she gave the leash a sharp tug to make me step in closer to her, my prick's eye level with her eyes, balls hanging under a heavy, stainless steel ring. She shuffled her feet apart as I stepped closer to her, proffering my throbbing length just a couple of inches from her face.
Suzy stared a little cross eyed at my cock head, her eyes moving slightly as it bobbed with each pulse. She sighed and licked her lips in a most alluring fashion.
"God you look fucking magnificent!" One of her hands came up to cup my low hanging balls, taking the weight of each, enhanced by the heavy metal, and feeling it in the palm of each hand. I gasped with the thrill of her touch, looking down as she lightly tested the heft of my balls. I gasped as she squeezed each slightly, enjoying the intense vulnerability of having the very essence of my manhood in the palm of this girl-woman's hand.
"God you feel magnificent!" She added in a low, husky murmur. "May I?" She didn't look up from her fondling fingers which she flickered suggesting she wanted to squeeze my testicles further. I let a low breath of anticipation, in a growing, rising thrill at this most intimate touch. My cock managed to harden just a little more, making the bobbing more pronounced with each heartbeat.
"You don't need to ask, prefect, he is yours in submission, to have and to hold. Make him really feel again who his mistress is today." My sister leant over to again reassure Suzy she was, for now at least, the mistress dominatrix of her brother. "Hands behind your head sweetie, leave yourself to the girls!" She ordered, we had worked out that was the way to stop me trying to direct the action.
"Fuck! I thought like their balls are so super sensitive I can't, shouldn't ever touch!" Suzy said, just lightly testing each testes with her fingers. My sister knew better, leant over and put her hands over Suzy's and squeezed, much harder. I Let out a puff of breath from the extra thrill of sensation and a drop of precum oozed precociously from my urethra. "Oh wow! They are so, oh so squishy!" Suzy squealed excitedly as she took over the fondling of my masculinity.
"Mistress bought a device, prefect, a clear plastic ball crusher, she gets them almost flat." My sister flicked a finger to scoop off the precum just as it was about to fall. "And that's not to be wasted." Jeez it was so fucking hot stood there before these two gorgeous women, my manhood palpated in their hands. It got even sexier when my sister lifted offered my sticky precum on her finger to our friends lips. Suzy at first hesitantly and then eager,y licked it off.
"Oh you lot just...just make me want..." Suzy licked her lips as they opened suggestively as stared fixedly now at the eye of my cock, palpating and squeezing each testes on her own now. I was instinctually stood up a bit straighter with my hands behind my head, pushing my groin and genitalia forward. Her enthusiastic massage was making me groan from the exquisiteness of being made to dance on the very edge of agony and ecstasy. Under my sisters tutelage this gorgeous young woman was caressing and crushing my testicles beyond thrillingly.
"Take it, prefect." My sister used one hand to lift my cock up as she gently pushed Suzy's head forward. Slowly I admired the exquisite sight of my cock easing into this woman-girls mouth. "No, keep squeezing them, my brother loves it and will cum harder." Oh my sister knew her brother alright. "Oh, and try not to swallow, prefect, so we can kiss and share!" Oh fuck yeah, she knew me and my perversions far too well for a sister, that was for sure.
Well, I really wanted to grab Suzy by her corn blond hair and pump her face onto my cock like a living fleshlight, but for now I would reserve that for my sister. Suzy looked up adoringly at me with my cock deep in her mouth, her tongue tentatively tickling as she explored my gloved glans. She looked the submissive one and fuck she looked, and it fucking felt, picture perfect like that. But just as I thought that and steadily holding my gaze she gave my nuts the strongest, sister assisted crush yet.
