Re: Arilou_skiff..Oh you have no idea..
She's bar hopping; that she's going to be under the influence of alcohol is an entirely reasonable deduction. And though it's stated nowhere that the brother was under any similar influence, the fact he doesn't say no to this lass that's landed in his lap says to me he's out there in the club looking to hook up, and being in the club most likely not entirely sober.
Why bother putting the effort in repriming the situation when it's already been primed for you, especially if you just want a quick fuck? Both twins were hot enough and capable of saying the right things to get her knickers off and into bed. It's no different to someone claiming a different name or profession or wearing a push-up bra to make themselves seem more desireable.
No one's saying it's a crime to go out on the pull for some casual shagging. But it does make her a risk taker, and risky behaviour sometimes comes back to bite you in the arse
