Because they are here for money and they know how RLC audiences work.
They have some experience on this.
They avoid overdoses although, today, Sasha showed he is a champion in bed, when motivated.
I only remember V at the end of 2017 when she was with M&S in the bathtube and bedroom. It looked that Sasha didn't want the threesome. Because V was drunk?
At the beginning V also wasn't nude at M&S. Surely these 3 know each other for some time and they know what, when and how to do things in order to earn money.
