Hellrazer III: The Sacrifice.

Kicking off with a quote from Satanist Anton LaVey, this video plays up the whole "doom / by evil monks" thing to the nth degree, and stars smooth and cut 1999 Zeusboy Robert Black being boned by a horny devil. Gregorian chants, pentagons, body bags, chains, ritual, it's all here... and is played pretty, er, straight, when Black is . First he's subjected to hot wax (groaning and struggling in vain) and a whippin'. Then a hung, uncut, horny demon (Gallo) shows up and works the now happily enslaved Black over, licking him off (loudly spitting out the flakes of wax he catches) from neck to cock. Smoochin', reciprocation, and a loud and raunchy ass-suck fest follows, including a romantic interlude with a dildo.
