Bruce's train ride home was one of the longest and loneliest trips out of London he'd ever taken. He'd liked Karen, and felt comfortable that they'd lucked out in finding her to help realize Yvonne's fantasies, but it was nonetheless an odd thing to do to hand one's wife over to someone else to have sex with. Many different thoughts coursed through his brain simultaneously, all competing for his attention. He worried about whether Yvonne would be all right, that she'd be safe and well taken care of, and that she hadn't gotten herself in over her head. Then he worried that she might enjoy herself too much, and would no longer have need of him and the activities that took place in their marital bed. He thought about what Karen and Yvonne might be doing together, and those thoughts caused his cock to harden. Feelings of arousal and jealousy swirled around in his brain, mixing with feelings of concern. He knew that from this night onward their lives wouldn't be quite the same, but as yet he had no way of knowing what form and manner the changes would take. Above all he hoped he'd done the right thing - for her, first and foremost, but also for himself, and for the two of them as a couple - in setting tonight's events in motion.
Finally arriving home, he unlocked the front door and let himself in, then flicked on the hall light and took himself up to bed. It took him a long time to fall asleep that night, unaccustomed as he was to not having Yvonne in the bed next to him, and his conflicting thoughts still swirling around in his head. On another night he might have been tempted to masturbate in order to help himself sleep, but Yvonne had asked him not to, and he felt compelled to honor her wishes. Once he did finally manage to sleep, it was fitful at best, as he tossed and turned a lot and woke several times in the night, realizing anew each time he did so that yes, he was indeed alone, and that yes, his wife was at that very moment in London, submitting to and having sex with her dominant female American lover.

Yvonne awoke the next morning to the sound of a toilet flushing, looking around briefly to take in her surroundings and recalling where she was. Daylight was peeking around the edges of the drapes, and she could faintly hear the sounds of traffic wafting up from the streets below. As she stretched she detected a faint odor of ginger still emanating from her own body, on account of the oil that Karen had rubbed into her skin the night before. The memories triggered by the scent caused her sex to moisten as she recalled them one by one.
Returning from the loo, Karen smiled at seeing Yvonne awake, and climbed up on the bed in a kneeling position, straddling Yvonne's face. "Eat me," she commanded. Surprised and pleased, Yvonne proceeded to do exactly that, eagerly complying with her Mistress's order and taking pride in her newfound ability to get her off with her tongue.
After Karen came she led Yvonne to the bathroom, and the two of them climbed into the shower together. The bathroom was done up in marble tile on the floor and walls, and the shower stall, which was more than big enough for the two of them, had glass doors and dual shower heads, one on each end. They took turns shampooing each other's hair and washing one another's bodies, sneaking in lots of gentle caresses and light kisses as they did so. They kept up a light conversation all the while, both of them teasing and gently commanding the other to "turn around", "close your eyes", etc. Once they'd toweled off, Karen took Yvonne back to the bedroom and bound her, spread eagled on her back, to the four bedposts. Karen fetched the strap-on dildo and its harness from the drawer in the nightstand, and fastened it in place around her hips, placing the small end of the dildo inside her own pussy. Lubricating the dildo with some more of the ginger lube, she then knelt between Yvonne's legs and fucked her. The burning sensation brought on by the ginger sent Yvonne over the edge almost immediately, and in no time at all she was moaning in pleasure.
After they both came several more times Karen untied her and put the dildo away, then fetched a white bra and matching boy short knickers from one of the drawers of the dresser, followed by a pair of blue Capri trousers and a grey hooded sweatshirt from another, all of which she put on. Turning towards Yvonne, who was still lying naked on the bed, she asked if she'd like some breakfast, and the two of them engaged in a brief conversation about what they were both in the mood for.
Karen phoned in their order to a local takeaway place, with a request that it be delivered, and turned back to Yvonne. "That will take a while to arrive, so while we wait I'd like you to follow me out to the front room. I think it's time we gave those tits of yours a proper flogging."
"Ooh, yes please!" Yvonne exclaimed, jumping off the bed at the prospect. Karen led her out to the front room and secured her once again to the St Andrew's cross, this time facing out into the room. The flogger she used had thinner tails, which had more of a sting and less of a thump than the one she'd flogged Yvonne's shoulders and backside with the previous evening.
Yvonne was enjoying the sensation and found it arousing, although it didn't cause her to spontaneously orgasm the way having her bottom caned had. Karen was still flogging away a short while later when the doorbell rang. She set the flogger down and opened the door, telling the deliveryman to set the order down on the table. He stepped inside and did a double take upon seeing Yvonne, naked and bound to the cross. Yvonne felt utterly slutty, and very aroused, at having Karen expose her and put her on display like that, and she was sure the deliveryman would have quite the story to tell his mates at the pub later.
After the deliveryman left, Karen untied her and put the kettle on for tea, and the two of them ate their breakfast, Karen clothed and Yvonne still naked. When they were done, Karen fetched Yvonne's clothes for her, and rang for a company car and driver that she had the use of to give Yvonne a lift home. When the doorman rang to let them know the car was out front, the two of them lingered in a kiss at the doorway for quite some time before Yvonne finally took the lift down and began her journey home.

Bruce was in the kitchen making his second cup of tea when he heard the car pull into the drive, and then Yvonne's key in the latch a few moments later. He set the cup down on the counter nervously, not knowing what the next few minutes would bring, and what it would all ultimately mean for his marriage.
