Mrs. Tan!

The gorgeous Mrs. Tan is lying in Donna's bed, while the intended occupant is curled up in a ball on the floor. You'd love to hear this story.

You share a look with your sibling and she prepares to restrain Donna. You get your ball gag ready to quickly silence the teacher when you wake her up.

You pull back the covers on the bed slowly, revealing the woman's figure. She is wearing only a bit of black lingerie. It's shiny and latex, revealing a bit more about her. Her breasts and pussy are uncovered, as the only piece that she is still wearing is the garter belt itself.

"Stop struggling or this will get worse," you say, looking her right in the eyes, "That goes for both of you. Got it?!?"

Both Donna and Mrs. Tan nod in obedience.

"Now then, I hear a rumor that Mrs. Tan makes all of the girls who are failing class to naughty stuff to her," you continue, "Is that the case here?"

Donna nods somberly, trying to look away. Your sister straightens her gaze out, however, forcing her to look you in the eyes once again.
