Mistress vs Shock Dildo - Who Fucks Better?

You little bitch never get enough. That's why I now have a new toy that takes the fucking work off my hands. The shock dildo only stops working when the battery is empty. Who has more stamina? The dildo or you? While the toy works your greedy ass cunt, I take care of your mouth. Finally I can fill both of your holes at the same time. So who fucks better?
