It's kind of messy and incoherent or something! First, she was full of it herself, and only then called her lesbian friend to make out with her. Wouldn't it have been more logical to invite a friend? And the boss spanked the employee, why not invite his girlfriend too - so to speak, to work both sides! And it would be interesting for him to watch, and the ladies would have fun. I think in this version of the reel would be much more interesting!
That the sister is interested in her foster brother's opinion is commendable. And assessing her worthiness from a man's point of view he can. But asking him to jerk off in front of her is kind of weird. He's going to get her, isn't he? Only this slutty girl is not scared at all - that's exactly what she wants. He ended up flushing a whole puddle on her tummy! Drove it.
