Erotic escalation

The butt stays still while the man licks it all over.

To the left, it hears a woman quietly whimpering. Silly woman, butts don't whimper.

The butt, now very well covered in saliva, can't help but notice that the licking all begins to focus in a single area.

Soon enough, the man behind the butt is very specifically licking the butthole.

The butthole feels weird. The butthole feels... Good?

The butthole isn't supposed to feel anything, but the butthole does feel good.

Mayashita closes her eyes and grimaces, trying to focus.

No, not Mayashita. Just a butt. Just a butthole, getting licked... Oooh, yes, the butthole likes it right there...

The tongue gets more and more aggressive, first digging inside the butthole, and then punching back and forth, in and out, like a minature, and very wet penis.

Mayashita isn't an anal virgin, but has never received this kind of treatment before. It's actually much nicer than anal sex.

She wants to indulge in it, to experience it fully, as a human, engaging in a full experience.

But no. She must remember. She's not a woman cheating on her husband. She's nothing. There's just a butt, and a butthole, that's feeling oh so lovely.

Still... It's not so easy to remain in this state of disassociation when something so delightful is happening down there. She's glad they can't see her face, because her facial expression is doing a very poor job of hiding how much it's turning her on to be treated like this.
