Doctor does urethral sounding on patient's penis untill he cum

Description: My play partner finally visited my clinic to became my patient! i didn't sound him for a loooong time, so i decided this will be what i'll do to him. i took 4 different sizes (size 5, size 6, size 7 and 8) and sounded him using them one after another. in the end i took a long, beaded one and sounded it until he cummed. and i gave his penis a small kiss at the end - well, in the end, he is my play partner.
