I don't know what you aiming here.

. Why the fuck would we need to know who having sex life and who doesn't?
And this part is even Funny because we have the knowledge, Arieth is fucked pretty much by everyone, Tommy Fucked Tania, and Heather. and etc etc. Why the fuck we would actually have to see that? Even for one Fucking render or two. it is not important . waste of time .
Unless, MC is walking on when someone is Fucking and he Witnessed it.

Realistically speaking we should have not seen at least 60% of the game, because MC is nowhere near. Why would we need to See heather try to Deepthroat Tommy?

.
of course this same logic apply to Josy and Maya, or any of the Flashback actually. But these are loopholes , because it's connected to the MC or the story, where as a random sex scene involving Rio and a costumer, does add nothing beside porn. which is pointless waste of development time. If it's not involve us.

.
so let's say Jill find love, outside of MC , may be with Rusty, we go out of a "double date", and after MC and his girl, go to their room, and Jill and Rusty goes to their own
why would we need to see as Rusy fucks Jill in the ass ? Instead of the Scene with us the MC and His girl ?
It seem like you actually talking about NTR, otherwise
I don't know what you aiming at, may be my poor english
