I think the arrival of the MC is coincidental, Jenny did not plan the arrival of a seducer male, but the letter from the father of the MC and the similarities between him and his Dylan convinced her. The rest, like strip and sexual flattery, should simply be contextualized, we are in a game for adults.
But one thing is true, we know for sure that two girls had sexual problems, Valery was abused as a young girl, and Jade was a prostitute, perhaps not in the true sense of the term (paid sex), but still used the sex as an instrument of barter. In both cases it can go towards the debasement of sexual intercourse, perhaps that's what happened to the girls. It cannot therefore be ruled out that Jenny's aim was to show the girls that sex is not a sin or a means of bartering. If that were the case, the characters of Jade and Rebecca, at least for me, would earn points. The first seems to be reluctant to give up that way of life, to the point of offering a blowjob as a reward and using the attractiveness to keep the MC close to her, while Rebecca would become a mystery, if she too had problems in the sexual sphere, what they could be, apparently she seems a naive girl, I would even say a virgin.
Then there is Aurora, she too could have had sexual problems, in her case it could be a commodification of beauty, her work as an actress seems to suffer a lot from her beauty, to the point that I expect her to turn up that to have a part has, or should have, sexual relations with any individual.
In general, however, all the girls seem to have major problems of insecurity. And not just the girls.
Even the 2 male characters, Vicky's brother and Eric, also here seem to be problems of insecurity, Eric does not like the place he is in, but I think he feels uncomfortable, out of place, I think he will become our friend in the future. Vicky's brother also has that rude and aggressive attitude that is often found in those who are actually deeply unsure of themselves.
