Gummi...Bis Der Arzt Kommt, 56 min

She has two slaves. She uses ones as her own personal doll, hanging him up to dry. The other, she bends over and plugs his asshole with a big, rubber strap-on. In the next scene, she can be seen in a sterile environment. The slave is carted in, and is left open to her many ministrations and any other tinkering she can think of.
