It's your birthday, and you're out at a bar for your party. I catch me alone, and convince you to go back to the bathroom for your birthday blowjob, making you think you're going to get lucky tonight. When you get back there, I pull your cock out and suck on it until you're close to climax, but then I stop and pull away saying, "Sorry, but you can't cum or the curse won't be lifted from me." I tell you how I've been cursed by a witch and that the only way to avoid becoming a nasty fat toad was to give 3 blowjobs, and on the third, the curse would be lifted and transferred to you. Unfortunately, you can't cum or I would start changing instead, and that can't happen. I laugh, relieved as you start shrinking and changing into a fat ugly toad. I say, "Hope you like your birthday gift sweetie, I hope you don't mind re-gifts" as you croak, horny and unable to do anything. I tease you, telling you the other two guys were allowed to cum and stay human, so you should've run into me earlier. "In fact," I say, "You had a pretty nice cock, we could've had more fun, but now no-one will ever fuck you again as a toad." I blow you a kiss wishing you happy birthday and thanking me for helping you escape the curse
