So, the sister is a experienced? Which means a slut? Yeah I am gonna pass on it. No harem, experienced slut womens are not my cup of tea.
The girls are not sluts! Just the female cop TBH...
She had a strong desire
over younger men, and she took advantage of you & the situation.
About sis,
She haven't experienced
sex before.
But, in the story she knew how it's done. It's not something new to her like just heard of it.
She must've heard or learn something somehow, and that's give her ideas on what to do.
* When i say i didn't want to introduce her as a
virgin. It was a developer preference not a fact in the story.
She doesn't really have to be inexperienced wasn't an absolute answer.
