When you are horny and think about engaging in an
extremely sinful,
degenerate sexual act, so you have a fap to avoid
committing a worse sin than "just" fapping
Yesterday, I suddenly had the horny urge to engage in bestiality while having a large sausage shoved in my ass, so I did a Salvation Fap for
damage control.
"May I ask, what sins did you confess at church yesterday?"
"Well, I had a short
shower wank, to avoid going to the whorehouse again"
"Oh, so you had a Salvation Fap?"
