"Well Gabe," Alexis says in a haughty tone, "I did say I planned on making you kiss my ass. So that's where we should start right? We can figure the rest out later. Good thing you're in a prime position!" she laughed, somehow pulling her g-string even tighter against your body.
You felt yourself pressed against the snob's anus and knew exactly what she wanted you to do. You shuddered at the sight and sheer size of the rich girl's back door. The last thing you wanted to do was kiss that thing, especially when it meant giving Alexis exactly what she wanted right away.
You tried to squirm your way around the g-string to find a way to freedom, but your captress felt your struggles against her sensitive backside and pushed a finger between her cheeks, pinning you to her anus.
"Nuh uh. You don't go anywhere until I say so. And what I say now is that you kiss it," she commands.
You shudder and hesitate.
"If shrinking further isn't enough of a threat for you, I'm sure my hungry ass will be more than happy to host you for the night if you don't want to listen like a good little pet," Alexis commands, putting more pressure on your back.
You grimace at the thought of being forced into her anus. At your size, and with the ability to shrink you further, you knew she would be able to make good on that threat. But you knew that if you gave in now, there was likely no limit to what other torturous games Alexis would force you to endure.
