It would be much better if he could actually take time to help her finish off when they are having sex.
As far as being clean, it's like night and day comparing to the previous tenants in this apartment.
Each time they go out to balcony first thing they do after they come back is go to the bathroom to wash hands/mouth. They spend a lot of time at home but Dasha keeps herself busy with various activities
either reading, knitting, cooking, cleaning, masturbating and not just watching TV all day. Good for her.
