Reading yours got me excited! Lol. Mine is somewhat similar: I fantasize about being transformed into a helpless, beautiful, curvy slut by my male arch enemy or something similar. He uses his wish, probably from a genie, to turn me into his submissive sex toy, bound to do anything he says while the real me is bubbling inside. He tells me to give him the most sensual blowjob while my backside becomes thickly diapered underneath my sexy maid uniform.
He commands my body to become incredibly uncomfortable from sudden intense urge to poop and commands that I cannot release into my diaper until he has released every drop of his seed down my throat. During this time he commands me to be so incredibly turned on by him humiliating me. The blow job session last well over an hour and the intense urge to poop causes me to climax numerous times. Meanwhile, even though I’m enjoying this uncontrollably, he notices a few tears running down my cheek to remind him of his arch foe trapped inside. This only turns him on more and he grabs my face, releasing his surprisingly large magical load down my throat. I empty my earth shattering load into my diaper. It seems to never end as I climax, my eyes rolling back into my head. When I finally recover enough, he has one of his minions clean me up while i’m a total mental wreck. He calls out to his beautiful minion to show him the footage she just recorded so he can send it to my wife. “We have even more fun planned for you tomorrow. I can’t wait to see what your wife comes up with!” He proclaims.
