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?"
