I woke, laying on my side, cock semi hard inside the warm folds of Susan's body, her back pressed to my chest, her tits in my hand. I lay there for a second until it repeated; a warm wet tongue stroked my ear, hot breath and the nibble of tiny white teeth against the sensitive lobe.
I turned my head, pulling free partially, but Susan barely stirred, even as my cock stiffened slightly now that I was awake. I could see a pale figure in the darkness above the bed, the lone candle that had lit our lovemaking long since burned down.
"Owner... I need to go potty." Came a familiar voice, not entirely happy sounding, the resignation that I had heard when I'd put Marie to bed was gone now that she was somewhat rested.
I led her downstairs, not missing, but ignoring, the tiny whimper of protest when we passed the bathroom at the head of the stairs. I led her down, out the back door, to her usual spot by the pool, taking the key from around my neck to unlock her belt.
"I..." she gasped as the belt came free, or at least the strap between her legs did. "I... have to crap." She looked down. I blinked, I'd already considered this, but I hadn't quite... you know... considered it. The bent waist pose I was teaching her for urination worked fine for that, but for this? I considered making her pee first, but discarded it.
"Can't I just... go inside?" she pleaded. "For this at least? This time?" bargaining now. I shook my head slowly, indicating a patch of grass near the fence and some low scrub bushes that was out of the way.
"Squat over there." I told her. Dinner sat badly with her, obviously, the smell and explosive voiding was disgusting, she cried the entire time, her legs shaking. I had her hold the pose over the mess so I could hose her off, cleaning her efficiently, washing away the worst of the smell as well. I walked her gently over to the light so I could inspect her; clean her more thoroughly with a wet rag. I was worried about irritation from the belt, but aside from a bit of chaffing from the belt and a little reddish irritation there didn't seem to be anything to worry about. I applied some oil to the prongs, and a little lotion to my pet's skin, hearing a faint sigh of pleasure at the touch. Had she not been bound I would have handed her the strap to see if she'd put it on herself, but she didn't fight as I gently pushed the tips inside her, locking her sex up once more.
I put her to back to bed without further ceremony, returning to Susan's bed, slipping behind her, slipping my air cooled shaft into her warm wet slit, hearing her sigh in her sleep, cuddling back into me like I'd never left.
Despite the interruption I woke at the usual time, Susan stirring to a sleepy half wakefulness this time, disappointed that I was leaving her. I considered ending the night with a bang, certainly my cock would enjoy it, but the reality of the situation was that I couldn't constantly satisfy all four, or even three, of the girls full time... I had to restrict myself to 'necessary' sex. Once Marie was trained, maybe I'd organize a daylong orgy/marathon... maybe I should arrange for a prescription of Viagra now?
There is a pattern to these things, a necessity of sorts. I didn't really want to deal with Marie, with her training right now. I wanted to enjoy my privacy, the quietness of an empty house. Normally I'd even head to the Gym on a Sunday morning, maybe swim in the pool... I was too sore today.
But training takes precedence over personal comfort. I woke her gently, helping her up off the bed. She bitched that she wanted to stay in, that it was Sunday... I would hear nothing of it, of course. I led her downstairs towards the backdoor.
"I don't have to pee, Owner." She protested behind me.
"You will pee, even poop, when I tell you. I don't want you soiling yourself, of course, but just because you are good 'right now' doesn't mean I want to listen to you whine that you need out later. Potty training, pet, its basic, even baby steps." She groaned, shrugging her shoulders in irritation.
"Will my Owner at least free my arms for this? My shoulders are killing me." I shook my head sadly, pushing her gently before me, rubbing her shoulders to help keep circulation going. Not that they were under that much tension, the cuffs weren't particularly tight, it was just an unfamiliar posture.
I led her to her 'potty spot' by the pool, had her adopt the potty stance, legs as wide as she could handle, even wider than she was really comfortable with, head down, resting her face on a piece of floaty foam I placed for her, I'd handle a more permanent solution later.
Once she was set I undid the chastity strap and massaged her lower belly. It took a while, she really didn't have to go exactly, and the eventual trickle was weak. Once she was done I wiped her clean once more and reattached the strap.
"Now what?" she asked abruptly once she'd stood. I ignored the tone. Once.
"This was a short lesson, Pet. You are, of course, free to do as you please until I want you for another lesson."
"Free? I'm bound and strapped and fucking naked!" she snapped. I shot her a look, it was all it took, I was impressed. She crumpled immediately, dropping to her knees in the grass, nuzzling my thigh, my cock with her face. "Forgive me, my owner." She begged earnestly. "I'm grumpy, I forgot." She continued her delightful rubbing, a nice touch.
"I forgive you, but perhaps another ongoing lesson?" she almost wailed. Of course she would worry, the first two kept her in a constant state of bondage, needing my help for the most basic of tasks. I tsk'd. "Trust, my pet. I think that your constant misbehavior is a result of your excessive hubris. A little humility... no more 'I' or "me', pet. You will only refer to yourself when absolutely necessary, and then only using the terms I use for you." I looked down at her.
"Your pet understands." She stated earnestly, looking up at me with fearful eyes. I patted her cheek.
"Very good, pet. Very good." I rewarded her with my own pleasure at her progress. It had worked before and I was certain it did again; she closed her eyes and rubbed against my stroking hand. I was really regretting not waking Susan fully with a belly full of cum... "Come with me, pet, I would like to show you something." I led her back to the house, and as last night, she stayed on her knees until we reached the patio, with no word from me on the matter, her method of showing her earnest desire to not be punished.
Understand that there are levels to discipline. First you have to establish dominance, even breaking the will of the animal you are training. Then you teach basic obedience skills. At this point the pet works purely on earning rewards and avoiding punishments. I suppose a great many people stop training their pets there and assume they've done something great. Those people have no idea what they missed.
