I know the whole punishment thing is very exciting, but if you haven’t yet got the hanging of even doing one edge then what you need is practise, not punishment.
Try and edge yourself three times in an hour, without cumming. And keep trying, until you can do it!
Once you’re actually capable of edging, THEN we can look at punishments for failing.
Fail? Just get up and try again, or do the fucking caterpillar!
