Toilet Slaves Scatology - Scat Study!

She is part of a medical experiment and she needs to submit a sample of her scat. Before her is a box where she needs to put her shit. So she takes off her pajamas, bends over, and asks someone to stick his finger up her ass. After that, she stimulates it further by jamming anal dildo up her anus. After a few minutes, she squats on the floor and ejects clumps of solid shit, hopefully enough to satisfy the requirements for the test.
