Send Tina home while you find some more slaves.

"Tina" you say

"Yes Mistress"

"I want you to go home and put on the sexiest panties you have, the ones you think will please me the most. I then want you to go over to my house and wait for me in my bedroom, here's the key so you can get inside. Once you get there you may masturbate if you wish, but you must not allow yourself to climax until I give you permission. Do you understand?"

"Yes Mistress" says Tina taking the key and hurrying off.

Having one **** is really fun, but having some more will be even better and you know a few people who deserve to be enslaved by you a whole lot more than Tina. Taking the book you go looking for the most deserving ?
