Anastasia Marinina sex with Mads Mikkelsen as her son interrupts them

Anastasia Marinina naked astride Mads Mikkelsen in bed as they have sex, most of her butt visible as she rides Mads Mikkelsen and we see her breasts.
A boy then enters the room and interrupts the couple, and Anastasia gets out of bed to close the door behind him. We see her butt as she then returns to bed and reclines while smoking a cigarette.
