Blackmailed

My stupid wife Iren was blackmailed by her students, who threatened to spread her nude pictures over Internet. They brought her to a hotel, where except for sex, she had to pose fully nude out of the room. At the very end of the session she was ordered to run to the end of the corridor and back. When she was almost back, young bastards jumped into the room and locked the door leaving her outside. That was real fun for everybody, except for Iren. Enjoy.
