Yes

The next girl that appears above you has red hair falling below her shoulders. She wears dark glasses and has freckles across her nose and cheeks. She has a nervous laugh that bubbles out and reveals only her top front teeth. She climbs the steps to reach you and removes her robe to display a very pale naked body. She has tiny tits.

"Now go ahead and sit on his face like we talked about," the lab tech says near your table.

She looks down at you and showis her bucked teeth and lets out a giggle. Then she turns and you watch her pale thin ass lower. She pulls her butt checks apart as she mounts on your open mouth. Your hypnosis kicks in and without thinking, your tongue begins lapping at her anus. It is bumpy like all the rest, but not dirty like most of the girls. You feel her shake slightly as she giggles above me.

"Now dear, this is serious," the lab tech says. "Pay attention to the slides and listen to the audio in these headphones."

You watch her place the headphones over her ears and the lights dim in the lab. Your tongue works and works on her asshole while she watches the slides. It seems like the process is taking longer or perhaps it is just you wanting this to hurry up and get over with. Then the lights come up and you hear the lap tech speak.

"Sorry dear. Something went wrong with the slides. We'll have to start over. Are you ok with this?"

You watch her head nod yes and realize no one cares about your opinion as you continue to fervously lick this girl's anus.
