If the girls keep being like Tracy and Jessy, then I think this feels like this is going to be more of a casual sex game with the biker plot being the main focus. No main love interest, just the women playing a part in the plot and the sex being a secondary idea in the game. I actually think that would be rather interesting.
But who knows, we haven't met the third girl on the banner yet (who I'm guessing is this Angie that Jessy was talking about).
Going the biker route, Tracy could end up being his "Ole Lady." While not a truly serious relationship, it's one that the MC would kill for should anyone attempt to harm her. But, it leaves him open to mess around with pretty much anyone. Now, should this story follow the "rules of the road" she'd not really want to know about ALL of his conquests, but is open to bring someone into the bedroom with him, or SHE could even offer up a friend for a night of fun.
However... if this follows the 1% rules, then if he becomes a prospect, Tracy and Jessy would then be property of the Club until he become a patched member. Meaning that anyone sporting a rocker could come and have their fun with either of them and there isn't jack shit that the MC could do about it unless he wanted to ... leave... the club. And if you know anything about Motorcycle Clubs, you don't just walk away. But, that is if Dimitri goes with actual biker etiquette and whatnot. Needless to say, with some of the lingo used so far, both military and biker, I have a feeling that our Dev isn't ignorant in the ways of either. Well, that or he's done an absolute metric fuck-ton of research... So I am extremely interested in how this will play out!!
