"Yes, ride that vibrator." Sakae says while slapping Kimi's feet while at the same time pressing the vibrator close to Kimi's clit.

Kimi squeals as she squirts all over the bed.

"That was the last time I'm going to be so liberal. Next time make sure you ask for permission to cum. Understand."

Kimi mutters, "Yes mistress." Through her o-ring.

"Good. Now let's move on to something else."
