Fearing more pain, Sumire took the cock from Ryuki's hands and started to fuck the cock slowly inside her ass. She felt two harsh blows across her ass cheeks.
"Not like that Slut, push back against it with your body so that you can bury it all the way inside," she heard Ryuki say.
Once again she was being forced to do things that she has never even thought about in her entire life. "Why am I doing this for him," Sumire wondered to herself.
Just then, Sumire felt the artificial ball sack hit against her cunt lips and she realized that she had the full length of the cock inside her, which she never thought was possible. The realization that she had a black cock buried in her ass caused her to begin to convulse in the initial stages of orgasm when she said, "Master R, I am so close to cumming. May I cum, PLEASE?"
As Ryuki watched his teacher slut fuck her ass, he could only smile.
Ryuki then told her, "Slut you can cum, NOW!"
