Brianna felt a little guilty about the underaged drinking incident a couple of weeks ago, since she was the one who introduced those naughty lawbreakers to each other in the first place. Genie reminded her that the end of this month was their special biannual anniversary time. So, they invited the unsuspecting Heather and Perry over for a little chat.
This will teach Perry not to let his cock guide him all the time, and it will teach Heather that there are some substances she shouldn't put in her body. It will also teach the neighbors to turn up the music really, really loud when Brianna and Genie have company, but that's acceptable collateral damage.
