John a new dentist, learning about this unique perk

"Okay, Amber, I think we're done here." You say to your patient, an 18 year old girl who's come in to have braces put on. It was your first time doing it on your own and you'd found yourself getting distracted by the young woman's curvy body, but the installation had gone smoothly.

"Aren't you forgetting something?" Your assistant Monica askes. "You know, cuming in her mouth?"

You look up at Monica horrified. "What!?" You gasp.

"Ugh, I've been dreading that part." Amber says.

"Now now, it's not so bad." Monica says patting her shoulder. "And it's really good for your teeth. Especially right after a procedure." Then she looks at you and asks, "Do you want some privacy?"

"Y-yeah." You mutter disoriented by the conversation. You stand there awkwardly as Monica walks out closing the door behind her.

After a long pause Amber clears her throat. "I don't mean to rush you, but I have a volleyball game to get ready for. Do I need to help you get off?"

You stare at the beautiful young woman in shock, your cock twitching in your pants. Even sitting in the dental chair under fluorescent lights she looks amazing. Her bronze skin shines, her pretty round face is framed by long wavy brown hair, her body is curvy and she her smooth slender legs are on display in a pair of cut off denim shorts. "Yes." You say but the moment is so surreal it feel like someone else's voice.
