I wonder... did you choose cum jackpot with speed of 170 now?
Your ass is so gonna regret that.
Just in case you were a coward and chose LOWER speed you will fuck your ass differently this time:
1. First tick of metronome, push the dildo as far in as you can
2. With every 2nd tick of metronome, push the dildo out, so it doesn't touch your ass at all.
Yes, that means FULL ass fucks (regardless of the speed you chose).
And if you fail at that task -10% to you final cum chance.
