Paradoxically, chastity is the most sexual thing I know. Not only does being locked up mean you think about sex from morning till night, but the near-impossibility of reaching orgasm also keeps you in a state of constant erotic tension.
First night I've spent in my pussy cage. Woke up twice with involuntary erections, but overall it went well. Now I know I can stay locked up 24/7 in this one. I put the key back in the lockbox timer set to 99 hours, and we'll see how it goes.
