"When you are ready to admit that you were wrong I will be happy to accept your apology and stop."
He gave her a few seconds before announcing that the next dozen would be delivered with greater force but not escalating further. He again used his left hand to caress the area and even ran it along the length of the divide until he nearly reached her pussy. He could not see the start of her pussy but those standing closest were fascinated to see her pussy lips slightly open and slightly moist.
Her reaction to each spank became more pronounced as each one landed. It was hard to understand what each sigh was trying to convey. The squeezing of her cheeks in time with the rhythm of the spanking seemed more an attempt to welcome the contact rather than to avoid it. It also involved the contact with his leg increasing as she moved up and down it. As he delivered the last of this dozen he could no longer deny the possibility that she was using his leg to masturbate herself.
He wasn't sure how to deal with this. As much as he wanted to humiliate her he had to confirm his suspicion first and then decide how he proceeded. He lent his head down as close to hers as he could and whispered for her to stay still. He slipped his left hand discreetly past her left hip and found what he had expected. Her pussy was soaking wet and he very quickly located her swollen clit. His head was now spinning, did he expose her arousal or did he indulge her? He whispered in her ear.
"If you concede defeat now I try and hide your arousal from the others."
To emphasis this he teased her clit with two fingers before slipping them just inside her excited pussy. Now he knew the nature of her earlier sighs, as they became louder. The sighing was interrupted long enough for her to whisper "no not a chance."
He removed his left-hand and without warning started to spank her again. Now he reduced the force and the time between each spank. Immediately her response changed dramatically. She tried to pretend to herself that her blatant fucking of his leg would not be noticed by anybody, other than possibly him. What she was certain of was that her body was betraying her in the worst possible way. It would not allow her to think of anything other than achieving orgasm. She felt crushed by her body's' demands as she was totally under his control.
There were at least two people who knew exactly the control he was enjoying. He was so confident at this stage that his left hand went back to her clit as he spanked her with his right. His fingers were not visible from the group now huddled around them. What was visible now was part of her dripping pussy and her anus as she relaxed her buttocks. The combination of the view of her bottom and pussy pumping up and down his leg and her noisy panting left those interested loving the spectacle.
Bob was now focused on causing her to orgasm from the insistent spanking and she was focused on cumming in whatever way possible. As she past the point of no return she wailed as if in agony. He spanked her harder and quicker wanting this to be the catalyst that triggered her orgasm. The two fingers rolling her clit added to the stimulation. When her body eventually slumped in exhaustion he stopped the spanking.
He asked if someone would cover Clara. She appreciated his gesture until she felt his right hand slip between her spanked cheeks and located her anus. Using his other hand he pushed her upwards against the finger that penetrated through her sphincter and deep inside her. The two hands worked skillfully in tandem and she was shocked that her body responded again.
As he felt her approaching orgasm again he asked her whether she wanted him to stop. It was no more than a whisper as she said.
"Please don't stop just finish me off I need to cum again."
This orgasm was short but very sweet. It took her more than five minutes after it ended before she was back to her powerful bossy self. Those who witnessed the events of that evening saw her in a different light. The stories recounting that evening became more and more extreme as time past by. If you have heard the rumors they are fundamentally true but also contain some pure fiction.
