Notwithstanding the fact that I had come three times in the last couple of hours, I was hard and ready. This was hotter than any fantasy that I had ever dreamed up and I wanted it to go on and on. I lifted the cat significantly. "Do you two think you have been punished sufficiently?"
Kristie answered, "I'm sure we need more so we will really remember it." Katie vigorously nodded her head in agreement.
"Then I guess we'll have to see what we can do about that." I took Kristie back over to the hanging chain. The few minutes rest, I was sure, had reduced the strain in her arms, but now I intended to strain them even a little more. I pulled her up until her feet couldn't remain flat on the floor and secured her wrist cuffs. Then I brought Katie over and fastened her in the same position, back to back with her sister. Both girls kept shifting around to maintain their balance - not that they could have fallen, chained as they were - their toes almost dancing as they shifted back and forth. Their backs and asses were pressed together and their entire bodies were taut with the strain of almost all their weight hanging from their wrists.
I left for a few seconds to retrieve a couple of other items from the closet in my bedroom and soon returned with a one inch dowel about four feet long. This had a number of holes drilled at two inch intervals along its length and eyebolts installed through a pair of them. I moved the eyebolts so that they were spaced about two feet apart and then knelt to attach each twin's ankle cuffs to them. This had the effect of stretching the pair even more, leaving only the ends of their toes touching the floor. I loved the effect this had on the muscles of their flat stomachs and the shape it imparted to their firmly muscled legs.
I stood and began to circle the pair, stopping to caress or lick or nibble at a sensitive part of their exposed antonymy. I sucked and tweaked their nipples, ran my fingers up their wet slits, and tickled their stretched stomachs. Their nipples were rock hard and sticking far out and I decided to see how they liked the feel of clamps. I had brought in two pairs of clamps, each set connected by a short chain. These were flat metal clamps, one pair with rubber coverings and one without. Both had adjustable spring tensions. But before I applied them I decided to further stimulate these lovely targets and began to lash them lightly with the soft leather cat.
I struck hard enough to sting and was rewarded by gasps and small cries or yelps. After maybe twenty strokes divided between the two girls, I stopped the whipping and held the clamps in front of their faces. Two pairs of deep green eyes opened wide, but neither twin said anything. I took the rubber covered pair of clamps and, after rolling her nipple between my thumb and forefinger, let one close on Katie's left tit. She sucked in her breath, but didn't object. Then, instead of placing its mate on her right tit, I pulled it around and clamped it on Kristie's right. The second pair had no rubber to pad the metal clamps, but they were smooth, not serrated, and when I let the first close over Kristie's left nub she only made a soft moan. I brought the other end of the chain around and let the second clamp close over Katie's remaining tit, bringing a similar groan from her.
Both twins were obviously very aroused and their juices were running down their legs. I stepped back and admired my sexy captives. Then I raised the cat and brought it down diagonally across Kristie's stretched stomach and on around her left hip, the tails just reaching far enough to strike her sister's hip also. I began to move around the two, lashing at irregular intervals, not severely but gradually increasing the strength of the blows. Mostly I concentrated on their stomachs and hips, but spread some of the blows along the outside of their legs. Then I began to add some to more sensitive areas: the undersides of their clamped tits, their shaved mounds, and the insides of their taut thighs.
The twins moaned, cried out and jerked under this treatment, but obviously were enjoying it. I continued, never striking hard enough to do any real damage, but always enough to sting. They couldn't hold still even when I wasn't striking them and were constantly twisting and rubbing themselves against each other. After about twenty minutes of this sexy torture I stopped and moved beside them. Using both of my hands I reached around and stroked a finger between swollen lips and penetrated into two sopping slits. I continued to play in this double fashion for two or three minutes, running my fingers in and out and stroking and squeezing hard clits. Suddenly I felt Kristie start to be shaken by a series of hard contractions which seemed to immediately set her sister off on her own orgasm.
I continued to finger them even after they began to come down and soon they were starting to come a second time. This time when they began to recover I moved around in front of Katie and knelt to begin licking at her super sensitive flesh. After a minute I switched around to lick her twin. I continued to move back and forth between them, eating one hot pussy while using my fingers on the other. I kept this up for several minutes until I couldn't take it any more myself. I was sucking at Katie when desire overwhelmed me and I stood up in front of her. With the girls spread and stretched in this fashion, my cock was at the right height and I shoved it into a very willing Katie in one long slide. Reaching around them, I held tightly to Kristie and began to rhythmically thrust against the hot body against my front while squeezing the hot body under my hands. As Katie and I neared climax I moved my right hand down and into Kristie's wet tunnel and began to stimulate her directly. I felt Katie start to convulse, squeezing my hard member with her internal muscles and almost immediately began to spurt my load into her. Our action - and my busy fingers - pushed Kristie over the edge and she joined us with her own climax.
I held tightly to the two girls as our breathing returned to more normal. The twins twisted their heads around in my direction so they could just catch eye contact with each other. I had the strong feeling they were about to quote a rating number again and decided to beat them to it. I quickly looked from one to the other and said, "Twelve."
All three of us laughed and I began to release them. After removing the spreader bar I took off the nipple clamps to the accompaniment of cries at the pain of returning blood. I then unclipped their wrist cuffs and they groaned as their stretched arms came back down. I helped them remove their cuffs and put an arm around each. "It's nearly midnight," I said. "Why don't we all go take a quick shower? We can use the bath in my room - it's larger."
Still with an arm around each naked twin I led them down the hall and into my bedroom. This had been the master bedroom and had a large bath with a tiled shower nearly five feet square. We rinsed with a lot of extra feeling around and then we all helped each other dry off. As we headed back towards the porch I said, "I think I should keep you tied up tonight. And the plugs should definitely stay in place. How does that sound?"
Again I saw sexy shivers from the pair and Katie said, "We'd like that. As long as you do more than just keep us tied."
I grinned at them. "Don't worry. I'm not sure I can manage it quite yet, but don't count on sleeping through the night. And I'm sure you'll need more attention by tomorrow morning, too."
I took a couple of long pieces of rope and ran them under the mattress from top to bottom. After putting the cuffs back on the girls I had them lie down on their backs, one on either side of the mattress. I attached their cuffs to the ends of the ropes, not tightly but enough so they couldn't move their hands down more than a few inches. Then I blew out the candles and climbed in between them.
