Now lube up your cock again.
I want you to slide that dildo (or whatever) into your ass while your stroke with your dominant hand.
(If you didn't want to fuck your ass with the dildo just do the edging)
Stroke at a medium speed (roughly one up-and-down stroke per second) until you edge.
Once you get to the edge I want you to start to fuck your ass with that dildo for 30 seconds, then stop. At that point I want you to start stroking again until you reach the edge.
Keep repeating this until you've edged 5 times.
