whenever rodimus gets too bratty or wound up drift and ratchet have a special punishment for him. they tie him up, legs spread with his ankles attached to a spreader bar, a gag in his intake. he feels so humiliated when ratchet manually opens his panel, squirts cold lube over his valve, and begins stretching him open clinically. then they take the biggest false spike they own and attach it to a fucking machine. rodimus always whines and begs behind his gag as they slowly slide it into him, pleading that he'll be good, they can untie him now, please, tears coming to his eyes at how much the dildo is stretching him out. then they switch it on at a steady medium pace and leave him be. they'll watch a movie together or cuddle or have conversation over dinner while rodimus lies bound on their berth, his valve getting mercilessly fucked by an unfeeling machine. it's so much, so big inside him and it goes so deep on every thrust it almost hurts how hard it's pressing into his ceiling node. he keeps begging and moaning but his muffled voice is drowned out by whatever show drift and ratchet are watching. when he eventually overloads, the machine keeps fucking his clenching calipers, never stopping. ratchet and drift usually come to bed at that point so they can lie on either side of him and read their datapads before recharge. they'll turn up the machine just to make him moan louder, trying so hard to writhe away from it in overstimulation, but he's bound too tightly. after a couple overloads he knows no amount of begging with make his partners turn it off, so he just lies there and sniffles and tries not to cum, every overload making him more and more painfully overstimulated. his valve is so sore and stretched. when he squirts all over the false spike, drift and ratchet just admonish him quietly for making a mess and go back to reading, letting rodimus sob and cry between them. he'll just keep cumming every once in a while as the machine keeps going. eventually he's leaking with every thrust, his poor valve so broken he can't hold it in anymore. maybe his waste tank gives out after being pounded by the massive false spike for so long and he pees himself, crying quietly in humiliation. by the time drift and ratchet shut the machine off, rodimus is trembling and sniffling, optics rolled back. his pussy is so swollen, sore, and gaping, he's covered in squirt and there's dried tears on his face, he's cum so many times he can't keep track. his valve is throbbing in pain, pleasure, and overstimulation, and he just whimpers as ratchet coos praise at him and drift unties him and gently wipes him down. he babbles out a promise to be good and drift and ratchet just shush him and cuddle him to sleep. his panel is left open all night, his poor pussy too swollen for it too close. he'll probably be walking funny for the next day or so, but he's learned his lesson
