A favorite of aggressive and sexually adventurous medical students everywhere, the storied Rob Job consists of a twofold stimulation of the human male.
The partner first inserts his/her fist into the Rob Jobee's rectum in order to roughly stimulate the prostate and seminal vesicles while using the other hand to simultaneously excite the glans penis.
The ultimate goal of the ambitious Rob Job is to achieve synchronous expulsion of bodily fluids and/or matter from both the urethral and rectal canals.
