Russian slut chokes on cock until she cums hard

A woman kneels on a stool while a man stands behind her, thrusting into her from behind. She leans forward, gripping the stool, as he holds her hips. At one point, she takes his cock deep into her mouth while he continues fucking her from behind. The setting is a simple room with a bed and open closet visible in the background. Her body tenses and relaxes with each thrust, showing clear physical reaction to the act.
