Yeah, you misunderstood, sorry.
1. You don't necessairily have to post an hour, but you post a timespan of your chosing.
2. When someone writes your name in the requested timespan the task is to cum in those 15s - not to edge, since that's what you would've needed to cum anyways.
3. If nobody posts in the requested timespan you may not cum for 24h.
Also sorry that this thread is kinda new so I guess nobody saw your post. Make sure to try again though.
