Being replaced

My wife, and mistress, has had my cock locked in various chastity cages for months. She hasn't unlocked me for a month but I'm hoping tonight is my lucky night. She left a note on the counter for me.

"Sissy, I want you in your gimp suit and ass cleaned and plugged before I'm home. We're going to have a lot of fun tonight! Love, your Mistress" I'm giddy with excitement, I love being covered in latex! I do as I'm told and patiently wait on my knees in the bedroom. I hear her come home, she changes in the spare room, then struts in wearing her own beautiful black latex, boots and stunning makeup. "hello sissy!" she says with a smile. "good evening mistress!" I beam back. "stand for me." she instructs, giving me her gloved hand to help me up. She strokes my face and kisses me slowly. "I've been so horny all day, I just need to be fucked so badly, so are you ready to satisfy your mistress?" she says full of lust. "yes mistress! Oh please mistress let me please you! Please!" she hushes me. "good, let me go get something." she turns to the cupboard and pulls something out. She turns back around with a new, massive, strap on in hand. I'm absolutely defeated. Mistress notices and grins. "you didn't think I'd want your little nub in me did you? I said I want to be satisfied, not to have a two pump chump unload a month worth of cum in me!" "I'm sorry mistress" she strokes my face, lifting my chin to look in her eyes. "you are my slave. Your pleasure comes second. Now put this nice big cock on so you can fuck me." I fit the strap on, with my caged cock protruding below the fake balls. She drops to her knees and wraps her hands around the plastic cock. She looks up at me with a big smile, "I wish I'd bought this sooner! Look, even before I locked your pathetic cock up you were never this well endowed! Oh god I need this in me..." she thrusts it in her mouth and starts bouncing back and forth on it. She's always been talented with her mouth, so I'm filled with sadness knowing I can't feel anything. One of her hands slip off the dildo and down onto my caged cock. She looks up at me while bouncing, her eyes show her joy and mischief.

She breaks off her sucking and climbs onto the bed. She unzips her latex to reveal her beautiful and soaked pussy. "come fuck me! I need that big cock in me! Come on sissy, be a man and fuck your wife!" I position myself between her legs, and slide the strap on inside her. She moans loudly as it slides in - I push until its all the way in and my cage is pressed up against her asshole. I slowly push back and forth, as she moans with pleasure. "oh god yes! Fuck me! Fuck me hard!" she moans. I pick up the pace and force, pushing harder and faster. "oh yeah! You've never pleased me this well before slave! I love your new cock! I want you to fuck me doggy style! I don't want to look at your face when I cum!" she changes position and I get back to fucking, this time my cage is smacking her clit. "ooohhhh mmmyyyy gooodddd" she screams, shaking herself to orgasm. I keep pumping, which she loves. She screams in pleasure and continues shaking. She eventually calms, sliding herself off the dildo. She turns around and kisses me passionately. She pulls away, holding my face in her hands. "you'll never fuck me with your own cock again" I can only whimper. "you wouldn't want me to sacrifice my pleasure for you, would you?" "no mistress" I say defeated. She laughs. "I'm glad you know your place. Now I've had a lot of fun, so I think it's your turn. Don't you think?" I perk up, hopeful she'll finally unlock me! "yes mistress, thank you mistress!" "where was this enthusiasm for my pleasure slave boy? Hmm? Well why don't you take your nice cock off then." she tuts. I remove the strap on, then look up to find her fitting her own strap on...

"on your back, sissy. It's your turn!" I'm defeated again, knowing my 'pleasure' is just being fucked in the ass. She lubes up the dildo, removes the butt plug from my ass, and slides her plastic cock into me. She pumps me slowly, as I try and find pleasure from it. I picture her bouncing on my strap on, cumming for a minute straight, and then her telling me ill never fuck her properly again. The combination of her fucking, those thoughts, and a month worth of unreleased cum has me moaning and eventually squirting cum out of my little cage. She bursts out laughing and stops fucking. "oh my god, it finally happened! You had a sissygasm! You've finally become a true sissy!" she scoops up the cum and feeds it into my mouth. "I've been waiting for this moment for months. I hope you understand what this means for you sissy. This..." she taps the cage, "will never need to come off. Why unlock you when I can milk you in it? Why unlock you when it could never satisfy me?" she shivers. "oh god I'm so excited! God, fuck me again! Put your nice cock on and fuck me again! Tell me about your little situation...". She strips her strap on and waits for me to fit mine. She lies on her back and has me between her legs. I start pounding and talking. "I had a sissygasm mistress, that means you will never remove my chastity cage. You enjoy me fucking you with a big strap on more than you've ever enjoyed my penis, so I will never get to fuck you again." she's moaning and shaking to orgasm, clearly loving life. She pushes me off her and has me lie next to her. Her hand wraps around the fake cock and slowly strokes it. "oh I'm going to enjoy fucking this..." she muses. I'm so fucked...
