I'm currently locked up and it's my favourite kink as a bottom. It's hot for me to be constantly straining against a cage and for the top to know I'm not going to cum at the end so it means that they can do whatever they want rather than having to be concerned about me. This usually brings out the dominant top in most people where they just use my body for their fun and in return i get the best fuck possible.
I always saw cumming as the sad end to sex but in chastity my bf can fuck me whenever and however he wants as I'm constantly horny and my only form of release is his release and after he's cummed in me and stops it turns me on more as i get denied and have to go on without cumming and still as horny as ever.
When i finally am allowed out and, usually edged for a couple hours, it's the best orgasm imaginable and them i'm locked up again.
