Give the to one of Emma's friends too

As you are preparing to spike Emma's drink with her first batch of Slave4U, you get a thought. You do want to give it to Emma, but now the thought is coming of also giving it to one of her friends, so you can have two slutty slaves that you can alternate between, so it doesn’t get too boring.

As she is taking her drink, you decide it is a good idea, and figure you could use Emma to the other girl you want. Ordering her to do so after she's taken Slave4U should be simple enough, after all. You might need a bigger stock if you do that though.

All goes well for the first week of giving the to Emma, and your relationship immediately improves thanks to all the sex you are now having. Emma is dutifully, doing anything you tell her, entirely submissive to you. You decide to get the bigger stock, and finally, order Emma to invite her chosen friend over for a girl's night, and spike her drink, which she dutifully does. Before the night is over you have a new for your use.
