A vibrating egg

Vaggie gapes as Charlie holds up a cordless, egg-shaped vibe. "Why!?" She squeals, jerking uselessly in her restraints.

"I told you, it's practice!" Charlie assures her before sliding the vibe into Vaggie's spread pussy. With a click of a remote, the egg starts buzzing loudly and Vaggie moans until it fades to a lower setting. "I want you to be a good girl while I'm gone. That means that you'll drink all your juice and you won't cum until I say you can. If you're a good girl, I'll give you plenty of rewards when I come back. If not, well, let's try not to find out, okay?"

"But, but, ah!" Vaggie sputters and moans as the egg's vibrating kicks up again.

"That's the spirit!" Charlie cheers. Pecking Vaggie on the cheek once more, Charlie quickly walks away while waving. "Love you, gotta go, bye! Remember to drink all your juice!"

"Fffuucckkkk," Vaggie moans loudly as the egg buzzes even harder while Charlie's footsteps recede.
