Sissy perks up

"Oh sissy, I see your nipples are hard and perky.
Let's see if I can get them harder. I have just the thing in my toybox."

(My cupping set I own)

"With the vacuum suction cupping, your nipples will get harder
and your little titties will get bigger, sissy."

"Oh it worked, sissy. And I see you're all excited

over your new bigger tits too. Good girl! Give Me a kiss."
