While engaged in her morning routine in the bathroom, Sosha pees in her pajamas in this video.
This video takes us inside the bathroom with Sosha as she gets ready in the morning. She brushes her hair, and then starts working on her makeup. From the way she is fidgeting, however, it seems as if she badly needs to pee.
Instead of using the toilet though, she simply lets go in her pajamas. As she puts her makeup on she wets herself, soaking her pajamas and making a puddle on the floor. Afterwards she takes off her wet pajamas and exits the bathroom.
