Eris stuck out her neck for the next man. It seemed as though her professor simply had a repertoire of handy men just standing by. She supposed as long as she played the good slave, she'd get rewarded.
He measured her neck and nodded, "I'll send it over when it's done," he smiled at Eris as he left.
David looked at her, "What a good slave... You deserve a little reward."
He knelt between her legs and fiddled with the vagina plug. He finally found a button and tapped it. The plug sprung to life and started vibrating inside her pussy. He pulled her a little bit forward and found the button in the ass plug and let that one vibrate as well.
"But no cumming," he kissed her breasts quickly.
He picked her up and carried her to a room that looked torturous. A pile of blankets were in the corners. Tables with leather straps and stirrups, chains hanging from the ceiling, chairs with dildos attatched, he smiled.
He pointed at the blankets, "That's your bed when I don't come home at night; I'll be grading tomorrow night. Your other bed is in my room so you can suck my cock if I need it in the middle of the night."
