Bound Sperm Sample

Description: My male patient is bound and unable to leave my clinic. he wears a strait jacket that i've chained to the ceiling. he is not getting away from my medical table! i have locked him in chastity as well. i tease him by grinding my ass on him. his cock throbs through the cage. i know exactly how i am using him today! i am going to take a sperm sample from him. i grind on him more to get him riled up before i unlock him from the chastity cage. i then use a pocket pussy to really rile him up. he orgasms in no time. i collect my sample easily. this is just the start for my male patient. i am going to collect sample after sperm sample, draining his balls.
