Original Sin 3
If you preferred to fuck me, well I have some bad news for you - I was really horny and came really quickly. If it took you more than 25 strokes to edge then you fail.
If you preferred to fuck Slut, then you fail if you took over 90 strokes to edge. Give yourself 5 hard smacks on the balls for preferring this traitor to me.
Otherwise, you passed and may write down a success.
For your next contest, I want you to smack your balls about once every second. Smack them hard and do not count smacks if they are too soft. Continue slapping your balls for as long as you can manage - but stop counting if your smacks become pathetic and weak.
I'll be smacking Slut's pussy while you do that and we'll see who lasts longer before begging for mercy.
