This is fabulous, and ironic, as I think I procrastinate… by writing! But it’s great to hear denial is working so effectively to help you get shit done.
I would ramp it up though, give yourself different levels of reward. It’s going to depend how things work for you but maybe upgrade to just a ruin for a chapter, or some other play you really love – using toys instead of just fingers for example.
Then, only on completion of a story do you get to cum.
Just be aware using denial like this will get counter productive if you get so horny you can’t concentrate! So, find what works for you and let us know how you get on!
