A couple of days later, after Bruce had left for work in the morning, Yvonne found herself up in her bedroom going through the daily ritual and specific tasks for the day that Karen had laid out for her. She started out by anointing herself with ginger scented oil, which had the by now usual effect on her cunt. She took some of the arousal cream that Karen had provided her with and applied it to her clit. She took her kegel exerciser - a Lucite rod with differently sized metal balls encased inside it, increasing from smallest to largest from one end to the other - and applied some of the ginger lube to it. When Karen had first started having her do this she'd only been able to hold the small end inside her while supporting the larger end with her hand, but by now she was easily able to shove the large end inside herself and hold it in place using only her pussy muscles while she engaged in a series of deep knee bends. Bruce had certainly appreciated her increased ability to grip his cock with her cunt when he fucked her, and with longing she realized he'd now have to wait until the end of the month before experiencing that pleasure again. She wondered idly whether Karen's cunt was quite as tight as her own, and what Bruce thought of it, or if he thought of her while fucking Karen, then quickly banished those thoughts from her head.
Her kegel exercises complete, she laid down on the bed and picked up her rabbit vibe, applying some of the ginger lube to it, then switched both controls on full and shoved it deep inside her pussy. Her task was simple in theory but quite difficult to achieve in practice. Karen required that she pump her pussy 2000 times with the vibrator without having an orgasm. She was allowed to take as long as necessary in order to do so, as long as the 2000 pumps were completed by the end of the day, but any time she stopped the count was rounded down to the nearest 100. So if she stopped at pump 378, she would start up again at 300 when she resumed.
She was able to finish her assigned task in a single session, although it took her most of the morning to complete it. The arousal cream on her clit combined with the effects of the ginger had her quite turned on, and she was only just able to catch herself several times right on the brink of having an orgasm. In addition her head repeatedly and continuously filled with images of Bruce and Karen fucking in the bed she was now laying in. By the time she completed her 2000 pumps she was both physically and emotionally drained, and for reasons she wasn't fully able to articulate, she started to cry.

A few evenings later Yvonne was at Karen's flat, tied to the St Andrew's cross. Her body was oiled with the ginger oil, clover clamps were attached to her nipples, and a vibrating egg was in her ass, coated as usual with ginger lube. Yvonne had come to find that she now craved the burning sensation brought on by the powdered ginger, and considered it quite normal for either her cunt, her ass, or both to be burning most of the time. Karen had applied some of the arousal cream to her clit, and was now seated in front of her on a kitchen chair, holding an artist's paintbrush. More of the arousal cream was on the paintbrush, and Karen was slowly but incessantly tickling Yvonne's clit with it. Yvonne would need to endure 42.195 minutes of her tickle marathon, mimicking the 42.195 km in an actual marathon, without having an orgasm. Images of her husband and Mistress fucking had flooded Yvonne's mind in the days following the banquet. She struggled with them now, and that struggle distracted her from her ordeal.
For her part, Karen certainly noticed her sub's distraction, reminding her several times throughout to focus. So although Yvonne was able to get through the tickle marathon successfully, she wasn't at all surprised when Karen picked up a leather slapper and proceeded to use it on her cunt. The sensation was moderately severe, and not at all unpleasant. Although it still required some struggling on Yvonne's part not to orgasm from the effects of having her pussy slapped, she found the overall effect to be quite cathartic. From somewhere deep within her being, she began to weep uncontrollably. Karen set down the slapper and approached her, cradling Yvonne's head against her shoulder and caressing her hair. "There there," she said, "what's wrong?"
"I hate that you let Bruce fuck you," Yvonne whimpered.
"Really?" Karen asked. "In that case, why did you allow it to happen?"
