Under the watchful eye of their demanding drill sergeant, a platoon of seasoned soldiers undergo an intense anal training session. Bare-assed and vulnerable, they're ordered into doggy position, presenting their tight, hairless anuses to the unforgiving sunlight. One by one, they're penetrated by massive, rigid dildos, grunting and groaning as they're stuffed full. The sergeant, a former porn star, ensures each soldier takes every inch, pushing their limits in this brutal, raw initiation.
