My wife also describes her anal orgasm as coming in waves. She also describes it as a feeling deep in her body.
She also never experienced an orgasm during vaginal penetration. Fortunately, she easily experiences anal orgasm ever since we went anal only years ago.
Glad to hear you’re having fun while discovering the many pleasures associated with anal play and penetration. Keep us posted on your progress.
Oh? Then I think I must have. If it wasn’t an orgasm, or a string of them, I can’t possibly imagine how an orgasm would be better, and I cannot imagine how an orgasm without anal could be… well, how you’d have one at all.
Her anal orgasms tend to vary in intensity with some being more powerful than others. I’ve found this to be true, even with the rather one-dimensional orgasms we men experience. Mine is always more powerful when I cum in her ass.
It sounds like you experienced the joys of anal orgasm. Try to replicate that feeling again by coaching your partner to fuck your ass in the way that feels best to you. Ironically, my wife experiences anal orgasm when I slowly and deliberately penetrate her ass as deeply as I can.
Congrats on your anal orgasm! I hope you have many, many more! It’s the reason my anal queen is an anal only girl.
Perfect description, haha! The same happens here, but I would add: “uncontrollably” or “as if it had a will of its own”. How delicious, how delirious!
Congratulations! May this be the first of many.
That sounds awesome, Firefly! So glad you could make this wonderful experience! Being able to let go like this, with all the negativity you had to work through, is quite hard, but so so good and important for great and liberating sex 
I’m morbidly curious, though: Was Mr. Firefly’s mind as blown as your own? Because I’m knowing you as he does, it would must have been an amazing and moving sight!
I don’t know if his mind was blown, but he was definitely having a great time and was a very happy man.
Actually, I’m not sure he realized it really, because it kept coming in close waves, I don’t think he was expecting that to be it. More like a one and done. And I didn’t start piecing it together until afterwards, but mostly because I was so caught up in the moment. …Which is absolutely amazing in and of itself, nevermind the orgasm. 
Thank you! Yes, uncontrollably is definitely a good word to add in there! My word, was that good!
Oh, and in other random bits and bobs - I’ve never done any sort of enema or enema adjacent clean out before and decided to do one. It might be a low level new kink.
