I Gave The Girl Next Door The Key To My Cock Cage

I'm big into chastity. Cock cages, belts, whatever. I had a girlfriend who was super into it to but we broke up a while back.

My upstairs neighbour is about my age, 25 or so. She's this cute alt girl. I kinda got the impression she's a top. So on a whim, I asked her to be my key holder.

She said yes and I've been locked in a cb3000 for 5 weeks now. It's so fucking hot. She wears the key on a necklace, I'm pretty sure her friends know about it. I'm so horny. She asks for proof pictures 3 times a day and occasionally blackmails me into doing things for her with them (which I consent to, btw).

She's been hinting at slowly feminizing me and I'm kinda into it..
