And so it went, they kept running, whenever they desired to orgasm, their Vibe was turned off. When it looked as though they were past the point of orgasm, it went on again. I was satisfied with their paces now. I was sure they could both maintain it for the balance of their exercise. Each time the Vibes went on, it was shorter and shorter before they said they needed to cum. I'm sure the adrenaline, the constant pumping of their legs contributed to their arousal. At one point, Chantelle warned she was close to cumming within 15 seconds of the Vibe being turned on, so she got a longer stretch without vibrations when it went off. Zoe and Monique were doing a good job of denying them release. It got harder to maintain their current pace as they neared the twenty-five minute mark, so I allowed them to slow down to an easier pace. At thirty minutes, they were allowed to stop. They were both breathing hard and their legs were rubbery. Both Vibes were currently on though we had to turn them off shortly after they got off.
"Leg machines now," I ordered, and they both got on the leg spreaders. I set the weights to something I knew would be difficult even with fresh legs for the two of them. "Three sets of fifteen, go." Both of them started working on closing their legs against the heavy weights. If they seemed to need a little encouragement, the whip snapped against their breasts and cunts or against the soft insides of their thighs. I did note how difficult a time they had with the first set, and reduced the weights for the second, and even more for the third set. As before, Monique and Zoe were controlling the Vibes and they would be going off and on as necessary to keep the slaves stimulated to distraction.
They finished those sets and the machines were reversed and they had to struggle to open their legs against the weights. I continued to provide encouragement to both with my little whip even as their pussies were stimulated by the Vibes. For both slaves, the amount of time the Vibe could run without them nearing climax was brief.
Next came sit-ups, three sets of fifteen, holding a medicine ball. They were sweating profusely, mixing with the cunt juice running down their legs, or stomachs, the two were so wound up. Next up were squats, their pussies flowering as they worked their legs more and the Vibes kept them at peak arousal levels. Last came pull ups, both working their chest and arms. I knew both of them were near exhaustion, kept busy for the last ninety minutes. Chantelle was really struggling, and the whip was required to chastise her more than Marcia. She couldn't finish her last set and collapsed to the floor, totally spent. She could barely speak when telling us her orgasm was close. I had Monique put suspension cuffs on her wrists. Marcia managed to finish her last set, then slumped to the floor as well. I put suspension boots on Marcia's ankles and suspended her upside down from the chin up bar, her legs spread, her arms hanging limply below her. Chantelle was suspended from the same bar, right side up, her legs tied to the side to keep them apart. Each woman's face was in the cunt of the other. I pulled the Vibe from each of their over-stimulated pussies and put it in the others mouth, soaked in their libidinous secretions. I tied their bodies together, hips to chest. I took back the Vibes, licked clean.
"When you have both received fifty strokes of the whip," I said, "you may lick the other slave to orgasm, but not until then. You will each count for yourself."
They both reeked of sex and sweat, being sexually stimulated and run ragged for the last hour and a half. I'm certain the scent of the woman squirming beside them was intoxicating. Their bodies were slick and would slide easily as they wriggled under the lash. They would both be desperate to cum, knowing the source of their release was mere inches away. Forced to wait, while the heavy, moist perfume of the other wafted in their nostrils. I started their whipping, going from side to side, one to the other. Sometimes a single stroke, other times two or three or four before going to the next slave. The only disadvantage of this form of suspension was only their backs, buttocks and legs were available to lash. Trying to whip their cunts would bring the leather strands too close to a face and I didn't want to risk it. Their breasts were pressed against the hips in front of them and also unreachable. Fortunately, the wiggling of each of them would be enough to keep their breasts stimulated.
I finished with Chantelle and only had two more strokes to give to Marcia. She was panting, eager for the whipping to be over and finally allowed to cum. But I stopped. I ran my finger from her shoulders up, weaving it back and forth, tracing some of the red stripes on her back.
"Please, Master, finish my whipping. Let me cum," she said, shivering at my feather touch.
"You need to cum slave?" I asked. I lightly ran my fingers up her crease to the rosebud of her ass.
"Yes, Master. Both slaves need to cum. You have tormented us enough. I'm dying to climax, I'm so aroused."
My finger slowly penetrated her rectum and she relaxed her sphincter, allowing me to push into her dark cavern. She grunted as I moved it around inside of her.
"Please, Master. Let your slaves cum," Chantelle panted.
I took pity on them. I don't know the last time Chantelle had orgasmed and it was at least twelve hours for Marcia. I gave her the final two strokes and they were instantly on one another, both of them shivering in screaming surrender to the other within seconds. She wasn't lying when she said she needed release. Since the first was so quick, I allowed them to pleasure each other to climax twice more before ordering them to stop. I untied their bodies and lowered Chantelle to the ground. Since my back was to my mother, I unzipped my shorts and shoved my cock in Marcia's throat while licking her from above. Given the erection I'd had for the last two hours, I found it easy to cum. Marcia's upside down position made it difficult for her to swallow my load and cum was dripping from her mouth to her nose and eyes. I continued to lick her until she had a fourth orgasm before tucking my cock away and lowering her to the ground.
"Go shower, slave. You're a mess."
"Yes, Master."
Chantelle was sent to the showers as well. Brianna telling her to return when she was clean to please her Mistress.
"How did you like my punishment?" I asked Brianna.
"Very creative. I'm sure they're both exhausted right now."
"They should be. Their muscles should scream for hours. Perhaps we'll let them use the whirlpool tub in a couple of hours after they've suffered enough."
Mom said, "You really do use and punish your slave all the time, don't you."
"Oh, yes. My main job when I'm her Master is to ensure she gets lots of sex, has multiple orgasms, and sees to my needs as they arise, constantly. If I were a woman, she'd be a very busy little girl keeping me satisfied. Fortunately for her, I'm not. I have to rest once in awhile, but I like Marcia to enjoy her time as slave and keep her happy. I'd like this to continue as long as possible. It's why I don't mind her having sex with other women. I'm incapable to having sex as often as she can, and she loves it so much."
"You think she enjoyed being sexually aroused and tormented by her sex toy, being denied her climax, hung suspended upside down and made to lick another woman to orgasm?"
"I believe so, but you should ask her yourself. She cannot lie to you. You're a Mistress and lying is a punishable offense. I think your presence made it even more arousing to her. She likes being used in front of others; it satisfies her exhibitionist streak. Doing it in front of you adds an extra element of humiliation, although I'm not sure it's the right word. Having sex in front of others she knows is more exciting than sex in front of strangers. Having loved ones know she's a sexy slut is worse and better than strangers knowing as she may never see them again. She's going to have to look you in the eye again knowing you see her for what she is."
"Yes," Mom said thoughtfully, "I can see where it would be more," she searched for a word, "something, knowing I've seen her suspended and whipped before she licked and was licked to orgasm by another woman. She will see that knowledge in my eye every time she looks at me."
"And get wet thinking about it."
"Is it the same for you, Brianna?" Mother asked. "Do you use your slaves the same way?"
"As much as I can. They are submissives and crave to be dominated. I use them for sex all the time. Other times they are punished, sometimes for no reason other than my desire to punish them. I have many slave girls, and all of them put demands on my time. Some can be delegated. Monique and Adele are senior slaves who will help discipline and control my junior slaves, but this service to me is contrary to their nature. They do it because they must in my service, but I must dominate them more to compensate for their wielding power for me. Monique craves to be punished regularly, as do others, but they wish to be petted afterward. Adele and Zoe do not crave corporal punishment as much, they wish their submission to be in servicing me sexually without my returning their affections. To give sexual release without getting it in return. That is the form their submission takes. They will seek release from others, seldom me." She reached down and stroked Zoe's hair.
"Having Sam here helps in a way. He can and does discipline my slaves when I ask and removes the responsibility from myself, Monique or Adele, as he did Chantelle this morning. Chantelle often enjoys discipline from a heavy hand and around here; no hand is heavier than Sam's. As long as he does not seek sex from them, they are content to undergo discipline because they know it comes from me. On the whole, they would be offended for him to use them sexually or for me to allow it, except some like Chantelle who loves cock as much as she loves cunt."
Chantelle returned and her Mistress spread her legs so Chantelle could bring her to an orgasm. Marcia arrived shortly afterward and she was walking awkwardly, her legs stiff and sore from her forced exercise. She knelt at my feet. Brianna reached her climax within a few minutes and I was hungry so we went to the dining room to eat. There was freshly cut vegetables and dips, finger sandwiches, salads, hot homemade soup and other healthy lunch choices. It was hard to gain weight at Brianna's; they ate sensibly and I expended more calories than expected having sex. I allowed my slave to eat at the table and serve herself. Soup got so messy if I tried to feed her.
After we were finished eating, Mother wanted to know more about how Marcia felt being a slave. I suggested going to the pool, but Mom said it was still too sunny and she'd prefer to go to the nursery and go to the pool after supper. I agreed we could go to the nursery. Before we went, Mom asked to see Marcia's back and bottom. You could still see striping but it was rapidly disappearing. The ones on her breasts and front were already gone.
"Her whip marks are already disappearing," Mom said, touching Marcia's bare flesh.
"She's going for her drug test and medical exam tomorrow. It wouldn't be within our agreement if she went bearing marks from her punishment. All marks of her slavery must be gone before then," I said. We started for the nursery.
"Master does nothing which would leave long term bruising. Nor does he want me to suffer extensive pain beyond the period of my punishment. It's been an hour since he finished. I feel nothing from the whip anymore, though my muscles are still sore from the exercise. Even so, if I were exercising myself, I would still feel the burn from it now, though probably less than Master made it. But vigorous exercise would be no cause for others to be alarmed at my state. He's not exposing my submission to others."
We looked in on the twins and they were still napping, though they would likely wake up soon to be fed again. They were eating, sleeping and pooping machines at present. Mom sat in the chair, Marcia and I the rockers. I put my hand on my slave's thigh. She smiled at me, a smile which never failed to warm my heart.
"Did you enjoy being punished?" Mom asked Marcia.
"I did, though not like you think of enjoy, Jane. It's painful, but not so painful as to be harsh or injurious. His use of the Vibe was twofold. By stimulating me sexually, he was flooding my body with endorphins, which are the bodies natural response to pleasure and a normal antidote to pain. I'm often stimulated sexually before I'm punished, so it will never be as painful as it might appear. My Master has found ways in which I orgasm even during the punishment, pleasure from pain. The second reason is to keep me on the edge of climax, which is a torment in itself. For ninety minutes, I was kept as close to an orgasm as Zoe could without stepping across the line. To be kept there for so long is both a torment and a joy. You need not climax to feel good from the sexual stimulation. It feels wonderful to be so excited, yet your body cries for the little push over the brink. To be kept right there is both extreme pleasure and sexual torture."
