Robin and Tommy

Lisa awakened first, leaving Mistress and me in bed. I knew right away that she was in full Domme mode by the way she immediately grabbed my boys, clutching them aggressively, and painfully I must say.

"You're mine today, bitch. Got it?"

"Yes, Ma'am."

"Did you enjoy surfing with the blonde girl?"

"Yes, Ma'am."

"Did you enjoy fucking her?"

"Yes, Ma'am, very much."

"Did you mention that Mistress and I want to get with her too?"

"Yes, Ma'am. She was quite eager for that. She's equally interested in sex with girls. She and Miss Claudia aren't exclusive, but they enjoy each other regularly it seems."

"Cool, she's really hot."

"She likes you too, said you're cute."

"I'll be happy to make her find out just how hot I am. Cute, hah."

I got an even harder squeeze to punctuate that and yelped appreciatively so she pulled hard on them to underscore her control.

"You probably didn't know Miss Barbara had Eric do some carpentry in the playroom while you were fucking Blondie. She told me to bring you down there as soon as we were awake. So, get up."

She didn't release my balls to drag me out of bed and led me to the playroom by them. She was relentless as she pulled me behind her.

When we reached the playroom, which was now beginning to look like a full-scale dungeon she led me to a contraption I'd never seen before other than in femdom porn. I believe it was called a ball stock. It consisted of two slim horizontal pipes attached by clamping threaded rods. She pulled my boys between them before tightening the rods to capture my testicles between them. I was well and truly imprisoned awaiting anything she might wish to do to her prisoner, me.

The door opened and Mistress entered looking gorgeous and flashing a very wicked look in her eye.

"Lovely, you've anticipated me perfectly, darling Lisa. Isn't he lovely with his big balls captive and presented so invitingly?"

"He is, Mistress."

"Begging for cruel attention."

"Very much so, Mistress."

Mistress handed Lisa a light flogger, raised an eyebrow with a grin and settled in a chair to watch the action.

"Care to do the honors?"

Lisa lit up, eagerly accepted the flogger, drew the tresses through her other hand while staring at me and subtly licking her lips. I knew my cock and balls were about to taste her whip and braced myself.

She softly drew the leather strands across my cock which curved down over my captive testes with a delicacy belying the evil gleam in her eyes. This was the version of Lisa that had surprised me when she first revealed it but which I had become very accustomed to as we delved into our switchy relationship.

With her free hand she caressed my cock and lifted it up to uncover her obvious target. The contraption that imprisoned me was dedicated to ball punishment after all. She continued to teasingly draw the tresses over my skin, adding a couple of prodding, painful pokes with the handle.

Mistress stared at the action, practically salivating, obviously eager to see how Lisa would choose to punish my captive balls.

Lisa spun the tresses artistically in the air, describing a figure eight pattern and creating ominous swishing sounds as they cut through the air. My eyes felt wide, and I'm sure reflected my misgivings about the pain I expected to endure imminently.

She leaned close and whispered.

"Are you ready, bitch. I think Blondie would be very aroused watching you at my mercy. Think she'd find this cute?"

"I don't know, Ma'am, she might."

"Has she got a sadistic streak?"

"Unknown, Ma'am. that didn't come up."

She grabbed my cock and tugged it hard, like she wanted to rip it out by the root.

"I bet this came up though, didn't it slut?"

"Yes, Ma'am it did."

"Did she suck it?"

"Yes, Ma'am."

"Is she a good cocksucker?"

"Yes, Ma'am, very."

"Could she take it all?"

"Yes, Ma'am."

"Really? She took your whole cock?"

"Yes, Ma'am."

"Wow."

"It was impressive."

"I thought I was the only one who'd ever swallowed that monster."

"You are still the best I've ever had, Ma'am."

She gave me a thin smile and delivered a sharp stroke with the flogger that shot a stinging flash of pain through my balls, then quickly reversed the arc to deliver a thudding strike to the underside that drew a grunt of pain from me.

"Did you return the favor?'

"Yes, Ma'am."

"Is her pussy tasty?"

"Yes, Ma'am."

"As tasty as mine or Mistress'?"

"No, ma'am."

I was definitely the recipient of her teasing games and knew that I needed to tread very carefully, particularly with my balls literally in a vise with her wielding the cruel flogger with evil intent. Mistress admired the scene sitting calmly and smiling like a cat eyeing her prey.

A flick of her wrist made the ends of the tresses bite cruelly into my captive scrotum and dig into my trapped balls. I let out a yelp and heard the women react favorably to my discomfort. Lisa followed that blow with a series of swinging lashes delivered in a figure eight pattern that caught each testicle in turn from the sides.

By the time she'd delivered five such blows to each, my balls throbbed severely, and I panted from the pain.

"Did you empty those naughty balls into Blondie?"

"Yes, Ma'am."

"Did you enjoy it?"

"Yes, Ma'am."

"Doesn't your cum belong to your Mistresses? Except when you have permission to give it to clients or for Miss Robin's or my pleasure?"

"I'm sorry, Ma'am, I thought that since you both knew that I was going with Katje today that I had permission, considering I already serve her every week."

"Did she pay you for use of our cock today? And isn't her Mistress Claudia your actual client?"

"She's not Miss Claudia's slave or sub actually."

"That actually makes it worse, wouldn't you say, Mistress?"

Mistress rose from her seat and approached me. She took my imprisoned balls in her hand and looked me in the eye.

"You broached the subject of her joining us for a frolic?"

"Yes, Mistress."

"And you said she was receptive to the idea."

"I would say she was eager, Mistress. She thinks you are gorgeous, and that Lisa is very cute. She said she'd love to get together and how hot that sounded."

She delivered a hard smack to the underside of my balls, then stroked them softly.

"I suppose I should arrange that with Claudia. Lisa, release his balls and attached him to the cross facing out. I promised to teach you a couple of tricks and I know you've been very eager to use your slave again."

Lisa freed my balls and led me by them to the St Andrew's cross where she cuffed my wrists and ankles, leaving me bound and available for anything either of them wished to do to me. Once I was captive again, she began fondling me roughly and stroking my cock to a full erection.

As roughly as her hands worked me, my arousal was building steadily and her hands cruelty demonstrated the pleasure I had learned that she derived from hurting me sexually, particularly when the pain revolved around my cock and balls. She loved handling me and as I discovered recently had apparently begun imagining using me like this even when I was nothing more than an adolescent fantasy hanging on her bedroom wall.

Whenever she Dommed me it fueled my desire to turn the tables on her next time I held the metaphorical whip hand. We'd had a hot relationship from the beginning, but when we began switching the blistering passion between us had blossomed into a firestorm. I must say that her increasingly sadistic use of me inspired my inner sadist to aspire to new heights. It was becoming tit for tat, almost a competition and I was contemplating some exciting treatment for her tits.

Mistress watched her working my genitals with avid attention, her breathing became deeper and the gleam in her eyes illustrated how much she enjoyed the same things as Lisa was indulging currently.

A look passed between the women that let me know I was in for increased intensity of the play I was enduring.

"I think he's ready. He's beginning to produce precum. That's very useful for penetration. Tease the opening with the tip of your pinky, using the precum to help you in."

Lisa teased my pee hole with the tip of her right pinky. She worked into me slightly with a reciprocating screwing action until she had penetrated almost a quarter inch. As I had become used to the stretching it felt very erotic and something Mistress had taught me to crave.

"This is exciting, Mistress. I'm fucking his cock."

"It's cool, isn't it, taking control of him this way?"

"I love it."

"Slip your finger out and lube yourself so you can go deeper, that's where the real fun is. Don't worry, he loves it, see how deep you can go. I'll plug him while you lube, I've found that really helps get him going. Open and stretched in both openings."

"Kind of like when both of you fuck me."

"Wonderfully similar."

Mistress spread my cheeks to expose my asshole and slathered me with lube, inserting two fingers to get a generous amount deep inside my rectum. She followed her fingers with a medium butt plug that she inserted fully in one push. I gasped at the invasion, and she gave me a hard slap.

"You know you love it, my little slut."

"I do, Mistress."

I was barely used to the intruder in my anus when Lisa returned to resume attention to my cock with her now thoroughly lubed pinky.

She took a firm grip on my thick, hard shaft in her left hand and brought her right pinky tip back to my slit. She resumed the screwing motion with the lube added to my precum facilitating the insertion and quicky she had her finger inside me to the first knuckle.

The feeling was familiar, very much like Mistress' similar insertions with an added component of who was doing it being an emotional change. My adoration of Mistress Robin actually began with the first time she took ownership of my cock in this very manner. My love for Lisa was more complex, rooted in its purely sexual beginning that deepened as our relationship morphed into heavy BDSM switching.

I groaned in a mixture of pain and pleasure as her finger found its way deeper inside my urethra and the look in her eyes as they widened in amazement and excitement with every millimeter of progress she made filling my hole and taking ownership of my cock.

Mistress looked over her shoulder, beaming with pride at her pupil and her progress filling my cock. She cradled my balls, complimenting Lisa's focus on claiming my cock and her other hand toyed with the knob on the end of the plug in my ass, rotating it like a video game joystick.

I found myself with a surge of endorphins triggering me into the deep black velvet of sub space. As I drifted into the transcendental realm I relaxed into the bliss and gave myself totally to the experience.

When I returned to the reality of my two Dommes working my holes, I found myself still possessed by their hands working my holes and Mistress sensually working my testes. My thought gradually coalesced on an overwhelming desire to worship both of them. I realized that Lisa's finger was now fully two knuckles deep in my cock and the plug Mistress was working in my ass was powerfully stimulating my prostate. The combination was fueling an impending ejaculation.

"I think he's about to cum, Mistress."

"Slip your finger out so he can blow it all out. Take it in your mouth, but don't swallow. When he's done feed it back to him."

"MMm, I like doing that. He likes to eat it straight from my mouth like that. Don't you, slut?"

"Yes, Ma'am."

When she withdrew her finger suddenly from my urethra, Mistress squeezed my balls and shoved the plug forcefully into my rectum and I began shooting a series of powerful sperm jets into Lisa's mouth. There were six separate expulsions of cum before Lisa removed her mouth and leaned toward me to met my lips. Her kiss allowed her to flood me with my own ejaculate. It had felt like I'd cum extravagantly, but as it filled my mouth it felt like an even greater pool.

"Don't swallow it yet savor it, hold it in your mouth."

Mistress instructed me as she continued playing with my balls. Lisa bent down to lick the last cum dripping down my shaft and happily enjoyed the last of my extravagant explosion.

"You may begin swallowing your cum slowly, slave. Savor it, make it last. You like eating your cum for us, don't you, slut."

With a mouth full of cum I could only nod in response and mumble.

"Mmm hmm."

Mistress continued working my balls as I gradually sipped the wad of cum Miss Lisa had returned to me.

"Take him to the bed, Lisa."

Lisa released me from the cuffs and led me to the bed where she lay me face up and bound my wrists and ankles in restraints that were attached to the legs of the simple bed. Once she had me arranged, she took my cock in one hand and my balls in the other giving them a firm squeeze. She stroked my cock and rolled my balls in her fingers until my cock returned to life and stood proudly at attention before shifting to straddle my face and settle her pussy onto my lips. Her cunt was drooling nectar, and I drank her present in happily. I couldn't see but felt Mistress mounting me and sliding her hot wet pussy onto my cock. She wriggled her hips, gradually working my full girth inside herself and finally let a contented sigh escape when she had finally fully impaled her hot pussy on my entire length. She was wonderfully tight around me, they and I gloried in being buried deep inside my beloved Mistress while licking and sucking Lisa's sweet opening.

It was amazing, such a joyful position they had me in. Being ridden by the two magnificent women I adored, offering myself as their human sybian, glorying in providing them pleasure by being used for their orgasmic release, repeatedly over the next half hour.

Lisa was at her greediest, punishing my mouth by grinding her pussy aggressively on my mouth and nose. I lost track eventually but I'm sure she came at least four times, leaving my lips bruised and swollen when she'd finally had enough.

Mistress rotated her hips and posted up and down, drawing back then dropping back down to drive my cock deep into her hot, grasping cunt. I know she came twice and there were shuddering sequences between her major explosions, like little aftershock that made her quiver and shake.

For my part I exploded twice, filling Mistress with what felt like quarts of cum deep into her womb to her delight, judging her exhortations to, "Fill me with your cum, slave, flood my pussy."

We all collapsed in a sweaty pile, idly caressing each other. Mistress held my cock in her hand possessively as it slowly deflated. She allowed the last of my ejaculate to seep into her palm and brought it to my lips, then climbed into the position Lisa had formerly occupied to allow the cum I'd shot inside her to slide out and into my mouth as she instructed me to clean her out.

While I accepted the return of my cum from my sweet Mistress's beautifully pussy, I felt Lisa's fingers begin toying with my cock and caressing my balls. There was no end to my bliss and the exultation I felt from the shared passion and the joy of the desire these magnificent creatures had for me.

Eventually sleep overtook us.

Come morning my enslavement to Mistress Robin escalated when she raised her head from the pillow.

"Lisa tells me she began training you to serve her through light latrine duty. Is that true, Tommy?"

"Yes, Mistress. She did start training me to accept her pee. It was awkward at first and I wouldn't say it came easily."

"Will you learn to take mine?"

"Yes, Mistress, I will serve you that way proudly. I think until I've had more practice it would be better to confine that act to the shower. I still had trouble containing every drop. I would feel very ashamed if I let any escape in the bed or onto the carpet."

"I would like your goal to be able to accept it without losing a drop every morning. And any other time I need relief. Shall I have Lisa instruct you further?"

"That would be fine, Mistress. I would like to earn your trust so I can accept your urine whenever you choose to give it to me. That will be a precious gift."

She stroked my cheek softly, looked deeply into my eyes and brought her lips to mine, giving me a gentle loving kiss.

"My sweet, Tommy. I do love you. Now come."

She took my hand and led me to the bathroom, had me lie on the floor of the walk-in shower and gradually squatted above my face before lowering her pussy down to my mouth. I gave her a lick to separate her folds and worked my way in, finding her pee hole and surrounding it with my puckered lips.

"Ready?"

I gave her a thumbs up gesture and a slight nod. She stroked my hair back affectionately, spread herself further using two fingers, and released her stream into my mouth. The hot, acrid fluid filled my mouth, welling up quickly and while I tried to swallow her entire bitter gift, I couldn't keep up, choked and coughed a bit up letting it spill out over my cheeks and some even washed into my hair.

She continued peeing until her bladder was empty and I licked her thoroughly, cleaning any residual pee from her folds, and finished by giving her clit a gentle kiss.

.

"Thank you, Mistress."

"You're welcome. You will work with Lisa to improve your ability to take everything she has to give and when she deems you ready you will begin serving as my urinal."

"Yes, Mistress, I will do my best to be ready very soon for you."

"I know you will. It will be a big achievement when you can serve me with worship and granting me relief in this way every morning. That will please me greatly."

"Yes, Mistress. I will be very proud to provide those two services every morning."

"Excellent."

"Good morning, Mistress. Did I miss any fun?"

"Tommy just had his first taste of my pee."

"Nice, did he do well?"

"Not too bad, but some did spill. I'm sure he'll gain skill with practice."

"I'll be proud to train him for you, Mistress."

"Exactly, you said you began training him in latrine duty and I'd like to continue with that. I'd like him to become comfortable and easy to use for light latrine duty whenever I require it, particularly first thing in the morning as part of his morning devotionals."

"Yes, Mistress."

"I will require him to worship me front and back and accept my morning pee and I would have you train him for that service until he is skilled at that trio. Now I am going to allow him to worship my ass with you watching to observe any flaws in his technique. I know you excel at anal worship."

Lisa beamed at the compliment.

"Thank you, Mistress, I do enjoy pleasuring your ass."

"Teach him your skills. Now Tommy, let Lisa watch you trying to please me. I quite enjoy having a hot tongue deep in my ass. You can do that for me can't you?"

"Happily, Mistress."

She straddled my face in reverse cowgirl aspect, pulled her cheeks apart to offer her beautiful starfish and lowered herself to meet my mouth. I started with a couple of long, slow licks, then teased around the puckered flesh with the tip of my tongue before beginning to insert the tip into her tight opening.

She took my cock and balls in her hands, caressing my shaft and rolling the boys in her fingers.

"I do love how hard you can stay even when you've just cum. My beautiful big cock makes me very proud."

I caressed her perfect firm ass cheeks and stiffened my tongue to gain deeper penetration inside her tight opening and with every millimeter I gained, the sweet sounds from her encouraged me and my efforts intensified. The feeling of pride that I always felt at pleasing her swelled in my heart.

"That's it, Tommy. Deeper, yes, that's so good."

Her flooding pussy was making a slick on my chin. Her hands had worked me to rock hardness and her thumb stroking my swollen glans was driving me toward an impending explosion. I could tell from the way she was working on me that she wanted to make me cum as much as I wanted to please her.
