You seem to have a high pain tolerance so this should be fun.

Put a binder clip on each nipple and one on each pussy lip. Using a string, tie the one on your left nipple to your left pussy lip and do the same on the other side. Tie the strings as tight as you can without pulling the clamps off. Put toothpaste on your clit and attach a regular clothes pin. Coat your pussy with hot sauce, spread your legs, and insert the toilet scrubber into your pussy. Scrub it for 15 minutes. After 15 minutes, press your vibrator against your clamped clit and continue scrubbing until you orgasm. Once you orgasm, continue to hold the vibrator against your clit for another 10 minutes. You may then remove all the clamps. After you remove the clamp from each nipple, immediately pinch it hard and twist it.
