This is my dream. I’ve done a month locked without release and six months being intermittently locked and despite being unable to masturbate and cum it was easily the best sexual experience of my life. I felt like a truly confirmed hungry bottom. Being fucked was more pleasurable than it had ever been to the point that I would beg to be fucked and when I wasn’t I would ride my dildo like there was no tomorrow. I had no control over my orgasms while locked but anal orgasms were regular occurrence. The beauty of it was that I was completely dependent on my Top for this to happen. If he didn’t want me to cum he would pull out or change his angle and leave me in heat, but also he could force me to orgasm against my will just by fucking me harder when I was close. That, in my opinion is the life a true bottom should be living on a permanent basis. No penile orgasms, but fully anally orgasmic and at the complete mercy of his Top for his sexual satisfaction. Total bottom bliss.
I have no idea if this is fictional or not, but damn slavefantasies could very nearly start a church around such a philosophy. Sunday mass and worship would be…interesting.
