Yes, he wants her to have sex with other men, but he wants to know about it.
He never says this in the game (I looked it up but I guarantee this dialogue you talking about is not in the ga,e) so I assume you are talking about the fact that if you were in his shoes you would want her to tell you everything.
The MC is not you.. The MC is Tony
--------
As I said in another post, not every day they have scenes in TAC and each of them have their own jobs, so not every day they (Anne or the MC) have time to talk about sex..
Anne is out of home for job a lot of day weekly... They call each other in the night
up to the CH15 is clear ( and n any case the dev decided to rework to fix the error that can confuse someone like you)
The only one the MC doesn't know about is Martin (this is written in the game!).... this means that after days or weeks or just the night of the clarification at the barbados vacation they told each other everything....
But...
if Anne omitted to tell him about Martin.... I think the MC must have omitted someone important too...anyway the old version stops here so we have to wait until tacos will reach the point where the sttory was aborted!
As i said i can't wait to see how the story turns out
If the MC do not tell her everything i do not see way she has to tell him... it is a mutual relationship!
Tony is interested in watch her when fucking other guys
but
Anne is not that much interested in whatch him with other girls
SHE LOVES TO BE WATCHED BY HIM WHEN SHE IS FUCKING OTHERS
for example here are dialogs from the game when Anne tells him what she have done some day ago at the SPA!
He want t watch her
She want that he watch her so much
PERFECT MATCH COUPLE!
---------------
Cheating is not related with sex.. she has his permission to do sex when he is not present... sometime happens that she forget bc she is tired from ger job
BUT sex does not involve her loving the one who is fucking her because she loves ONLY her husband and she knows the MC likes to watch her cum....
Cheating in this game is only when the husband or the wife they feel a special love interest another man/woman
Or at lest that is how understand the storyline... they are in romantic relationship since many many years... at the start of the game they boyj decided to separate the sex life from their own mutual romantic love that is still strong on all chapters!
