Japanese cute girl, Yui, is very sadistic girl unlike her pretty appearance.

Yui cruelly sinks her strong teeth very deeply into the skin of a poor man, who is blinded and bound.
He moans with acute pain, but Yui doesn't stop biting him.
She leaves lots of her huge and deep teeth indentations on all over his body!!

Enjoy Yui's cruel&powerful biting man's body!!

*In this part, she bites back, sides, nipples of the man.
