I've got high hopes for that, since there are plenty of other ladies around, and FMC has traded a favour for a service...
... until then, she was the only lady in the building who hadn't done such an act... I got high hopes indeed.
In Turning the Page,  the FMC first sexual act was flashing her breasts, followed by giving a reluctant handjob. It took a while from there to build up slowly.
I just hope that in this game, they wrap things up better, because in their last game, it did a brilliant build up, but it took too long to wrap things up.
