Use a wooden spoon or similar for all spankings
Spank your pussy 50 times
Clamp your nipples extreme
spank pussy 50 times again
use your best vibe until you cum
Take off the clamps
spank each tit 25 times
Roll 10 dice. On 60, you're done. Otherwise start again
Next time, 59 or less to stop, then 58, etc
for bonus points, do the dare standing in your highest stiletto heels
