imagine going to confession and telling the priest guiltily about all the sexual fantasies you have, all the nasty things you imagine
and you expect to be given advice and some prayers as penance, but after a long, serious silence, all he tells you to do is come back tomorrow at a specific time
and of course you agree
but instead of ending up cleaning pews or helping with candles, the priest puts you on your knees between his legs in the confessional
"your penance," he explains, and forces his cock down your throat. "now, remember: think of how sorry you are for your terrible sins and be quiet."
when confessions are done, you're sitting in a puddle of your own mess, tears covering your face and drool all down your front, and he tells you that you did a very good job, but that you must come back next week to confess any further sins
you try to be good, to not sin, but all you can think about is the priest's cock in your throat, how it made you choke and throb and want
so the next week when you return, dutifully, you admit these thoughts. he demands you explain them in great detail, and then tuts.
"come again tomorrow."
and you do. this time, he puts clamps on your nipples before forcing you down on his cock, and it hurts, hurts so much you're crying, even though you do as your told and remain silent while he takes other people's confessions
and the cycle repeats.
you never do manage to overcome your sin, but the priest always knows exactly how to punish you, so you think it balances out
