Kate and Rob were just dropping Amy off at her apartment. Rob stayed in the car while Amy walked her friend up to the door. A million thoughts were running through his mind as he watched his wife and her best friend talking for a few minutes at the entrance to the apartment complex.
Rob was worked up and all of the thoughts going through his mind centered on getting Kate home and to bed - but none of his thoughts concerned going to sleep.
The evening had been exquisite non-stop pain and humiliation for him as Kate had explained to her best friend Amy, that they wanted her to hold the key that unlocks Rob's chastity device. The device he had been wearing for the last month.
The depth to his humiliation went further when Kate was handing Amy the key, and Amy refused it from Kate. Amy handed the key back to Kate insisting that Rob be the one to hand her the key and that he must ask her directly to hold the key for them. Had he not been constrained, he knew he would have exploded and cum on the spot.
As he waited impatiently for Kate to return to the car, he watched the two women talking. Amy was facing out towards the car and Kate had her back towards him. It appeared as if their conversation was soon coming to an end.
Finally, he thought, he could get his wife home and up to bed. Amy leaned out a bit from their conversation. She was clearly looking back towards him as she smiled at him. Certain and knowing that he was paying attention and watching them talk, Rob watched as she said something to Kate that caused Kate to also turn quickly to glance back towards Rob, before returning her attention back to Amy. He was sure that he had been involved in the conversation in some way. He wondered what they might be talking about.
In that moment, one of his biggest fantasies suddenly turned to reality and he was very shocked as Amy leaned in towards Kate, embraced her, and the two beautiful women, the two best friends, began a very long and intimate kiss on the doorstep.
Rob could not believe what he was witnessing in front of him. His wife Kate was kissing and being kissed by another woman! As far as he knew, it was the very first time Kate had been kissed by a woman. His heart raced as he couldn't believe what he was seeing.
The kiss seemed to go on for an eternity and Rob's encased cock cried out to him as it tried to burst through the hard plastic enclosure that held it in check. In reality the kiss might have lasted a minute, but to Rob it went on for eternity until he saw Amy finally pull away, turning her face towards him once more, she gave him a short wave and smile, then turned to enter her building.
Kate paused a minute as she watched her friend enter the building before she finally turned and made her way quickly back to the waiting car and Rob. She opened the door and quietly slipped into passenger seat. Her short skirt rode up as she settled into the seat, allowing Rob a glimpse of her lacy black thong beneath her skirt.
Rob was speechless as Kate turned towards him. In the dim light he could see her lipstick - their lipstick - smeared upon her face. His cock sent needling pain through his body as his imagination worked double time. He simply stared at his wife in disbelief.
He was about to say something but before Rob could utter a word, Kate brought her finger to her mouth, shushed him and said, "Just don't say anything. Just get me home - now!" Rob did as he was told and they drove in silence. Both of them very caught up in their private thoughts.
Just minutes before they arrived home he watched as Kate lifted her hips off of the seat. He nearly lost control of the car when Kate reached her hands beneath her skirt and pulled her thong off, dropping it on Rob's lap.
They wasted no time. As soon as the car stopped in the driveway, Kate was out and heading for the door. Rob followed right behind her, clutching her lacy thong in his hand as they arrived at the front door at the same time. He could feel the wetness in the thin material of the thong. His wife must be dripping wet under her skirt, he thought to himself and fumbled with the keys.
Kate moved aside as Rob unlocked the door to their home and they stepped inside. To this point they had not spoken since leaving Amy's. That did not change now. Kate was inside last and closed the door quickly behind her, not bothering to take the time to lock the dead bolt behind her.
She stepped towards Rob, reached and pulled him close for a sensual and lust-filled kiss. It lasted no time at all as she pulled back, then pushed down on Rob's shoulders.
"Down on your back, Rob. Now!" Kate commanded of him, as he dropped to his knees on the hard tiled entry floor. For the past month now, with Rob locked in his device, Kate was regularly taking a more dominant role when it came to their sex. Clearly, in that moment, Rob was her sub. Kate became his Mistress and she was in command. He complied immediately.
No sooner had he managed to lay flat on his back, his wife Kate was lowering herself to her knees beside his head. In one motion, she raised one knee over his head and was straddling him above his face. The light material of her short skirt flowed over his head, immediately immersing him in darkness Kate's over-whelming and familiar scent of her sex. It was strong tonight. The strain from his containing device shot through him as he felt the warm skin of her soft thighs caress his face as she lowered herself even lower.
With his eyes shut, he instinctively lifted his face upwards towards her sex. His tongue darting forward until it made contact with her smooth, shaven and sopping wet folds of her pussy. He had never known her to be this wet and excited before. The lust and passion of the night was sweeping them both away. As his tongue and mouth feverishly worked over Kate's pussy, she squeezed her thighs tighter and moaned.
And combination of Rob's oral ministrations and Kate's urgency and need led to her pressing ever harder and faster into his face with her pussy. She forcefully allowed herself to smear her wetness across the entirety of his face. She used her body to force herself onto his face, his mouth and his tongue into her most sensitive spots - all of their combined focus on her sensitive clit.
Rob could barely catch his breath, and in that state of bliss, Kate couldn't care less. This was her need to be filled. This was her thirst to be quenched. His face was just an instrument for her. He was simply a breathing toy - her toy.
The wave began to swell within her. Kate was not being gentle. She pushed harder than ever, raking her hungry pussy across her toy's face. Using him, she felt the waves of orgasm inside her. The sounds of her excitement echoing in the room when the dam burst.
Rob began stealing breaths of air when he could. His face smeared and dripping with her juices. Kate's thighs trapping him. He felt the urgency rise within her too. He didn't care that she used him such a violent way. In the moment, his only role in life was to please and pleasure his wife. His only need was to fulfill her need, her desire.
