Don pushed his finger as deeply as possible into Kelly's rear opening, causing her to rise up even further onto her toes. He moved his other hand around in front and began to lightly tug and roll her clit which was now extending out from its hood. He twisted his head around, lowered his mouth to her nipple, and began to lick and tug at it with his lips and teeth. Kelly groaned even louder and Don only increased his efforts. For ten minutes he kept up the teasing stimulation, frequently allowing his rigid cock to brush against her sensitive areas and push hard against her body.
Then suddenly he stopped everything and stepped back, bringing frustrated cries from his victim. But she didn't wait long. Don immediately picked up the cat with the soft leather flails. His first stroke across her rear was so soft it felt like a teasing brush to Kelly. It was repeated on her front and the soft leather slowly dragged up over her stretched tits. A half dozen times Don allowed the soft leather to just kiss her skin, not stinging, not tickling, just making her nerve endings stand completely on edge.
Then, suddenly, he slammed a stroke hard across her ass. It was done without warning or build up and almost together with Kelly's sharp cry, red lines appeared on her white skin. Five or six more followed, striking her ass at different angles and in slightly different places. These stung and wrung cries from the stretched woman. Soon her entire bottom was colored red and Don delivered the next stroke to her stomach. However, this was once again the light, teasing stroke, bringing no pain at all. Several times he lightly touched her flat stomach, the fronts of her thighs, and her tight breasts with the teasing leather. Then again without warning a sharp blow landed across both of her firm globes, the ends of the tails wrapping around to sting the side of her right breast. Again Kelly cried out at the surprise and the pain of the stroke.
Don whipped her front as he had her ass and soon it, too, was covered with red lines. Her nipples were standing out as large and hard as he had ever seen them and distinct trails of moisture ran down the insides of her thighs.
For nearly thirty minutes Don kept the girl tightly stretched and used the cat to both tease and sting. Kelly was feeling the strain in her muscles and the sexual arousal of the treatment was nearly driving her out of her mind. Tears of both pain and frustration escaped her eyes and trailed down her face, mirroring the moist trails along the insides of her thighs. Several times Don gave her especially hard and vicious cuts, mostly across her ass but some also to the particularly sensitive spots: her breasts, the inside of her thighs, and her pussy.
Kelly had become aroused beyond anything she had expected. More than anything, she wanted Don to take her down and fuck her, giving her the release she craved. But he seemed determined to prolong her agony of anticipation. Then, surprisingly, she felt herself start to near orgasm just from the whipping and her imagination. But before she could achieve her release, Don put down the cat and again began to run his hands over her abused body. "No!" Kelly cried. "Don't stop now! I need to come. Whip me harder, Don. Please!"
A little surprised, Don still didn't hesitate to comply with her request. But instead of the cat he picked up the "Swiss" paddle, the wood frat paddle with the half inch holes across its surface. From personal experience he knew that the sting of this instrument was tremendous. It could really hurt and the victim had to be warmed up to even begin to enjoy its sting. Well, Kelly was certainly warmed up. Now he raised this device and brought it down with considerable force across the red globes of her stretched ass. A scream escaped her lips and Don was at first afraid he had struck too hard, but instead of the safe word he half expected the cry from Kelly's lips which followed the scream was, "More!"
He complied. After two more of the vicious swats, each accompanied by a scream, Kelly started to convulse in orgasm, loud cries escaping her lips and convulsions jerking her taut and restricted body.
When her breathing began to slow somewhat, Don moved around in front of her and moved to give her a hug. But to his surprise she tried to press herself against him, rubbing her body against his, wrapping her legs around him so she was hanging completely by her wrists. "Fuck me, Lover," she cried as she broke the kiss. "Take me down and fuck me hard."
Surprised at her continued high state of arousal, but certainly not disappointed, Don lowered her arms. He released her wrists from the ceiling chains, but clipped the cuffs together in front of her. He picked her up in his arms and carried her over to where they had placed a mattress on the floor. The mattress was resting on a sheet of plywood with attached eyebolts at convenient points around the edges. Laying her down on her back, Don took her wrists and pulled them over her head and clipped them to one of the eyebolts. Then he placed himself above her and lowered down until his cock just touched her rhythmically winking pussy. At the first touch he lost any restraint he still possessed and plunged hard into the hot, wet tunnel which was eagerly awaiting him. Both of them cried out at the swift, single stroke of penetration and Kelly locked her ankles together behind Don's back. They struggled like ones possessed, and perhaps they were, as they drove their bodies hard against one another. Don reached under her and grasped the globes of her ass tightly in his hands, his fingernails digging in, pulling himself as deeply as possible into her. Kelly arched her back and clamped her heels together even harder as she drove back to meet each thrust. After what seemed to be both forever and far too short an instant, Don exploded, his balls contracting and spurt after spurt of his hot juices surging deeply into the demanding woman who was beginning her own intense climax. For seconds, or hours, both were lost to the world and then slowly they began to come back to earth.
"That was fantastic, Lover," Don whispered between still rapid breaths.
"Unbelievable does not do it justice," Kelly whispered back.
"An I squishing you?" Don asked.
"No. I want to feel your weight on me. Stay there and press me hard."
They lay together, Don's weight pressing down onto Kelly, until he felt himself begin to shrink. As he slipped out her, he rolled off the bound woman and reached up to release her wrists. He kissed her and asked, "Want to stay the night? You can go by and get some new clothes on the way in the morning. I won't dock your pay if you're a little late to work."
Kelly laughed at him. "Since you pay me the standard researcher's wage - about half of poverty - and I'm expected to work twice a normal work week, I suppose you can afford to be generous," Kelly teased.
"Oh, you exaggerate," Don answered. "You know I pay you far more than your wildest dreams anticipated, and look at the fringe benefits."
Laughing, the couple kissed once again, Kelly pulling him back down on top of her. "Oh, you demanding wench," Don complained. "Am I going to ever be able to get any rest when you move in here?" he grumbled.
"Not if I can help it," Kelly responded.
The next day Kelly moved most of her stuff over to Don's house and put up an ad up to sublet her apartment. She expected to find someone, but was still surprised when she got a call within two hours from a girl who turned out to be willing to pay the full rent. Kelly made arrangements for her to move in in two days and she and Don took an evening to clear out the rest of her possessions.
They settled into the new domestic arrangement with surprisingly few difficulties. Since both worked together, they rarely took more than one car to the school. They had already known that many of their tastes - from food to music to reading material - was similar. They found they seemed to have more in common than disparate. The only real problem which started to surface was also held in common: they wanted to spend all of their time at sex. After a little serious discussion, they agreed to somewhat restrict themselves so they could accomplish the necessary items in other aspects of their lives. Work at the lab continued on a regular schedule even though both would rather have spent half the morning in bed. They scheduled time for workouts - other than sexual - and Don tried to complete his teaching duties without the need of homework. Within a week they had settled into a most enjoyable routine.
Don had been a little afraid that spending all day and all night with Kelly might result in their getting on each other's nerves. He had often read or heard about similar problems from married colleagues who were both in the same field. But he and Kelly didn't seem to have that problem. They both loved their field, and both were good enough that they didn't feel the need to turn work into competition. Or when competition did infrequently creep into their professional careers, it was of a friendly nature and neither felt threatened by it.
At night and on weekends they continued to lust for each other as much as ever and satisfied that lust whenever possible. Generally they made love two to three times each day and usually spent time in the playroom two or three times a week, sometimes for short periods, at others maybe for most of a day. Kelly usually enjoyed the victim's roll, but Don also spent time bound to the frame and horse while Kelly wielded the whips and paddles.
