First of all, congratulations for your vid. They´re all amazing!
I´d like to see the girls more often in tight skinny jeans like in the older videos. Its great to watch them shit in the casual street clothes they wear when they usually meet their friends. Especially Karina looks great in tight jeans.
The second suggestion is to work with 2 slaves. One swallows the shit and the second one just cleans the asshole.
