@BorisKitten,
I have a truly evil one I cruelly did to my then beloved.
Said beloved still had a friendly and happy relationship with his most recent ex., who was a very nice woman.
It was the seventies, and anyhow, I had a pretty tolerant view re the odd sexual adventure by partners.
Anyhoo, the ex decided to move to another city to get a qualification she could not, then, get here.
Beloved turned up at my place one night unexpectedly, looking kind of guilty.
He was very loving for a while, and then announced he was just dropping over to see the ex, and would be back in a couple of hours.
It was absolutely clear that the visit to me was a kind of guilt/worry thing, because, also clearly, he and ex had planned a happy bye-bye bonk.
I actually thought that was sweet, but decided to be devilish and pretend I hadn't caught on.
How I tormented that poor man!!!
"What a lovely idea" I said..."I'll come too!!! I'd love to say goodbye to her!"
Anguished excuses about why that, while a great idea, wouldn't work on this occasion from beloved.
Innocent queries about said excuses from evil dlowan.
More desperate wrigglings from beloved.
Finally, I had mercy, and waved him off.
The return: "I'll just have a shower before I go to bed" We all know what the quick shower upon return means!!!
I decide to have more fun:
"Darling, don't be silly, you're fine...just hop into bed."
Declarations of especially vigorous work activities that day from beloved, talks of evil odours, couldn't possibly inflict himself upon me smelly etc.
Protestations that I found his body odour enticing.
Eventually, I couldn't torment the poor man any more:
"I do hope the bye-bye bonk was a great one?"
Confessions I had known all along and had just been teasing him.
Poor fella, after initial intense embarrassment, joins me in hysterical laughter.
