Our latest medical examination video, shot on the same day as part 2.

Three more Marine lads are made to get naked from the get-go, thanks to the well-imbursed M.D. who performs each exam.

Each Marine grits his teeth and allows himselve to be probed and handled, all in the name of medical science.

The finale of each procedure is the hands-on testicle examination, as the rubber-gloved hands of the M.D. toys with each of six healthy gonads in search of any surface anomaly - after which the attached Marine turns, bends over and is instructed to RELAX whilst his sacred sphincter is briefly violated by a latex-covered digit.

Ow!

60 minutes.
