*Include behind the scenes 1) SIL is already in the bathtub as you walk in. She immediately addresses you as MASTER. You hold up something for spanking and naturally she stands up and bends over - by now she knows what's going to happen when you have a spanking object in your hand. You give her a few spanks and this is where the camera switches to your wife starting to masturbate. She tells you to spank her sussie harder and you do so. So basically the camera switches a few times between each act. The spanking on her wet ass leaves extremely red marks. - this is perfect in concept, and would ask that as the switching happens my wife needs to show she is getting more and more turned on as her sussie is worked over harder by me at her direction. Need to see that bit of creeping in from my wife, maybe she masturbates harder or moans more when she sees the welts develop. Additionally if you are up for it can the spanking also include back of thighs. That's just a personal favorite area for me, but up to you. 2) The next act can be your sil turning around and lean over the edge of the tub and you fucking her mouth/throat/face. This goes on to her being vaginally fucked while she's sitting on the tub seat. I would tweak it in that here too would be great to have my wife interject as she wants it be harder and more degrading on her sussie and this is what gets her even more turned on and worked up as she continues to masturbate and watch. And you guys are extremely good at the ""throat"" fucking roughly so no guidance from me on the how. ;) As to the vaginal fucking the same point of my wife is now crazed with seeing her sussie completely degraded and destroyed which again I'll leave to you guys. 3) This goes to the extreme where your wife tells you not to finish inside her sussie but to make her cum while her sussie watches as you cum inside your wife and have your sil clean off your cock. - This is a perfect ending.
