I want you to try to go like this for three days, three whole days without cumming. At least three edges each day.
And on the night of the last edge, you take a coin, and just before you’re about to cum, you flip it.
Heads you cum, tails, you stop.
You can flip it again tomorrow night, after three more edges, see if fate wants you denied even longer… And day, after day, until you get your ‘heads’
