You're my son and you join me in my room to get ready for bed. You came back from a birthday party that wasn't too fun for you, but I snuck some balloons in my purse from the party to play with. I had one too many cocktails with the other mothers, and I'm a bit tipsy. I start blowing up a 12" balloon and say you can take out one from my bag to play with too, if you like. As it swells and grows, I notice you getting a boner. I tell you this is normal in young boys, don't be embarrassed. I tell you to strip down and get your pyjamas on. When I see your poor young cock, I tell you that you need to relieve this pressure. It's okay, go ahead and jerk off, I won't look. The balloon gets a big neck and my cleavage pops out and my cheeks swell, I decide I'm going to see how big I can make it! I blow and blow, and you jerk and jerk, and suddenly it explodes and so do you! Oh my! Did that scare you son? It scared me. Let's do another. I lay on my stomach, sipping my hot toddy, and my dress rides up, revealing the lace tops of my stockings and mommy's huge, lovely ass, with no panties! Your mother is so bad, wearing a dress and no panties to a birthday party? You get another boner as your mother blows the big red balloon. You can't help yourself, so you jerk off again. now mommy is horny and she lays on her back, showing you her pussy. Shamelessly, she teases you about being hard for your mother and her balloons, since she sees you staring at her body and the round, taut shape of the balloon. She huffs and puffs with powerful lungs, making the 16" balloon stretch to impossible proportions. You're rock hard with anticipation, and you know it and your cock are going to blow again!
