So I've been up and spun waaaay out all night long, and up until about 15 minutes ago have spent literally the past 5 hours and some change fucking the absolute hell out of my girlfriend without pause, and when I say that, I mean HARD, and during basically all of the latter 3 of those 5 hours, have pretty much been in a condition of constantly RIIIIIIGHT on very edge, which I love, because it feels amazing and makes me never want to stop, and I have absolute control, so I only cum when I actually let myself, so I can always do that indefinitely every time, and when I finally do allow myself to let go and cum, it's indescribably amazing. However, after being fucked so hard for such a crazy long time without any respite at all, and enough orgasms of her own already to have lost count some time ago my girlfriend finally told me she wants me to cum, because she is totally worn out, and she wants that final ultimate dumbstruck orgasm that happens when we both cum together. Naturally, I was more than willing to oblige her and proceeded to double down and fuck her even harder and even faster, and let my control and focus go so we can finally cum together in that awesome, mind blowing final wave of complete and utter ecstasy that ends such sessions, but to my soon to come agitation, I notice that rather than going over that edge finally, I instead feel myself approaching closer than I have all night, right up to the very pinnacle, and naturally, based on that sensation, I believe I'm about to fully cum, and hard at that, but it is building in waves, verrrrry slowly. I'm thinking that I'm about to cum myself into a literal stupor if it's building so slowly and with such steady intensity, so I brace myself for a ridiculous orgasm, but as I fuck her harder and harder and feel myself right up on the tipping point for 30 seconds, 45 seconds, a solid minute, 2 minutes, then 3, I realize that I am physically exerting myself with this sustained level of intensity that I'm fucking her with that the very moment I would have finally reached it, was instead the moment my body could not continue at that pace with out finally needing a moment to recuperate before I could continue, so I relent, despite being sooooo close to achieving what promised to be a supremely intense orgasm, much to my irritation, but I still think it's alright. I'll just take a moment to let my body unwind release the tension I had just built up, and then I'll get back to it and cum myself brain dead. I take a minute, and then I go for it again. 10 minutes further on I realize the exact same thing was still happening, and I once again can't continue to completion before my body gives out, and am forced to stop a second time, and after a couple more minutes, my girlfriend had fallen asleep after having her brains fucked out for almost an entire night solid, and I totally get that, so I decide I'll just take matters into my own hands, literally, and I'll just get some porn going on my phone and make the last big push by myself, but unfortunately, I have quickly been reminded that for the last several months now lately, I have become so desensitized to all the porn I have found, kinky and fetish type stuff included, that I can no longer get turned on enough to cum to it, which brings me to this point right now, frustrated, out of porn ideas that will do it for me, typing on here with one hand while I stroke my cock with the other in what is more and more seeming like what will ultimately be a totally futile attempt to get that amazing orgasm I was so sure just a short while ago I was about to have, and becoming steadily more and more frustrated and disappointed. Edging ain't always a good thing I suppose....
