No, you're not gonna give her the satisfaction. You refuse to kiss her ass again.

After a couple minutes of rubbing her ass in your face, your lungs start to burn. You feel like your drowning between her soft cheeks.

She laughs as she bounces up and down again, taunting you for your failure.

"You're pathetic. Too pathetic to be my slave, in fact."

As she starts swaying her hips again, your flailing grows weaker, you realise you're probably going to die under here if you don't do what she says.
