Centurians of Rome (1981)

Caligula's empire ... Ruled by Passion! Destroyed by Lust!

Roman countrymen are sold into slavery for not paying their taxes during Caligula's reign as Emperor. Orgies take place and include: a guard being rimmed by a slave who is being sucked by another, shooting into faces, mutual masturbation, and more. Other encounters also include spanking and butt-fucking, chains and sweat.
