In the dimly lit barracks, the sergeant leads a secret training session. He watches, stroking his enormous cock, as the recruits tentatively explore each other's bodies. Their inexperience is evident, but the sergeant's commands are clear. He guides them through their first gay threesome, teaching them to worship each other's cocks and assholes. The room fills with the sounds of slurping, moaning, and wet flesh slapping against flesh. The sergeant joins in, his big dick stretching the recruits' tight holes, until they're all covered in sweat and cum, panting and spent on the cold, hard floor.
