But doctor can you explain what my neck pain has to do with your fingers on my ass?

Today i have a consultation with the doctor and without really understanding why he tells me to take off my pants and get down on all fours on the table. i only came because of a pain in the neck but i am not able to protest when he starts to put his fingers in my ass without stopping. every time i like it more and it makes me more horny his way of fucking my ass without stopping with his fingers. i end up on my knees and with his cock in my mouth moaning like crazy.
