The thing that makes me smile the most is that people create stories in their heads, and convince themselves that theirs is the absolute truth, about a story that they are not telling.
The only truth is that Stefany and Oliver are a couple, who after having had an unpleasant moment, mutually decide to try out their erotic fantasies.
Yes you are right, she feels pleasure when she fucks Arnold or Erik, but I don't understand why she shouldn't feel pleasure? When the husband fucks Mrs Sayuri and Jasmine, he feels pleasure, but no one protested and called him a cheating slut.
But you are very wrong when you think that she does it just because she wants to fuck with anyone, because what makes her enjoy it the most, is seeing her husband very very horny, while she is fucking with someone else, that's why she behaves as a slut only when her husband can enjoy her sexual games, obviously except for her way of dressing, let's say slightly provocative.
So trying to pretend that she's a slut who just wants to fuck everyone who breathes is just a waste of time, because that's the furthest thing from reality, wife and husband get along better than ever before, and just as he likes watching her play with others, she likes it too watching him play with others, as happened several times during the story, and for me this is not cheating but sexually sharing the partner with other people.
Regarding what happened at the spa, it is explained very clearly by Stefany that she had not noticed that the video call had failed, also because in previous video calls, Oliver was more inclined to enjoy the video rather than talk.
I hope that my ideas on the continuation of the story are clear enough, if not I will be more explicit, this is and will remain netorase.
Maybe in the future I'll try to do other stories where wife and husband aren't so close (who knows what the future holds), but this story isn't like that.
See you
