Time for your ass to have some pleasure or pain, depending on the speed you chose previously!
This is HOW you are going to fuck your ass:
1. At first tick of the metronome you are going to push the dildo in.
2. At every 2nd tick of the metronome you are going to push the dildo out, leaving the tip inside (unless you are told otherwise).
So one could say, that you fuck your ass with half the speed of the metronome.
Now,
Fuck your ass for 30 seconds with the metronome speed you chose.
Pick new speed and take a guess what's on next page.
