Correct me if I'm wrong, but not only is there no sexual interaction depicted between one of MC's in-game conquests and another male without MC's permission, there is no such interaction depicted without MC's presence.
Yes, and no... sort of.
Whilst I'd forgotten about John's ED problem, (cheers for the reminder
@Skaldy ) Rick (Julia's BF/ex-BF) has been "seen" with Emma (putting a terrible "performance" in for a young guy) and it's safe to assume he'd already been with Julia sexually, since his insistence in Julia putting out for anal with him is Jason's "in" for actually progressing sexually with her.
Whilst I don't remember Julia explicitly stating that they had sex, I'd say it's a safe assumption over all.
Kevin had already been, at least, getting some action from Rebecca at school (nothing beyond oral since she tells Jason she's never been with anyone other than her husband sexually), and obviously is getting action with other women that we've yet to be (if ever) introduced to, outside of allowing a hardcore shoot with Julia and a follow-up threesome + DP shoot with Jason being involved at the same time.
I'd say that she's probably still sexually active with her husband when he's at home, whilst enjoying sex and her time with Jason more.
With Rachel, I'd be more inclined to go with sexual relations between her and her husband are more on the decline/not as often as she'd like, for whatever reasons. She (funnily enough
) is much more interested in Jason's "magical sexpertise" than with her husband.
It probably helps that Jason (for the most part) comes across as a more caring character than what most of the women have been written to deal with (possibly except Janice, because we don't really know much about John and Janice's history).
Given the backlash from some in this thread alone at the "introduction" of John, the man who is married to Janice, and has been as much a father to Jason and Julia as Janice has been a mother, I kind of want to see the other husbands be introduced... just to see the ego induced "rage-splosions"XD
I do kinda like the idea of MC corrupting Mom so much that he's effectively pimping her out to his school bro. It's an interesting twist (ha!) that's sort of unique to this game.
Whilst I personally avoid that path (I detest Billy in general) I do like that it's handled in a way that doesn't come across as particularly malicious on the part of Jason, and Janice seems pretty fine with it.
Of course, given some of the things Danielle has said about her sister, I think Janice probably is probably happy enough with that kind of thing in general.
On an unrelated side note here, I find it amusing that Danielle is the only member of the family without a "J" name.
Janice, John, Jason, Julia... Nice to see variety.
