Update: a fan edited this one beautifully to add some lovely sound effects, and I think you will really enjoy it! The sound of balloon inflation and balloon sounds as I rub it over my body add greatly to the realism, and a haunting ending is added with street sounds, birds and other ambient noises as you float away...

It's your birthday and I come to the door, your new BFF, helium balloons and cake in hand. You're new to town but we invited some friends, but none of them have shown up...but me. I try to cheer you up, give you kisses on the cheek, admire the balloons with you, your favourite colour--bl*e! When you bl*w out the candles on the cake and make a wish, though, things start to get strange. You start swelling up and turning bl*e. I panic and go to c*ll 911 but you stop me, you say your birthday wish is coming true. You asked to turn into a balloon just like those ones I gave you. I freak out, demanding to know why you would do such a thing, I'm so upset. I confess, now that you're inflating more and more, and can't talk anymore, you can only bob your fat balloon body up and down or side to side to say yes or no, that I have a crush on you. I was hoping this party might lead to something, a kiss, anything, but now you've ruined it. I'm so disappointed and sexually frustrated. I hug you, since you seem upset, and press your fragile balloon body into my tits. It feels so good, unexpectedly, to be close to you like this, even as a balloon. I take off my clothes and press you to my naked body. At least I can have you like this. I kiss you, taking everything I wanted. I start touching myself and rub your balloon body to my p*ssy until I c*m, not caring that I could easily pop you if I get too rough. When I'm finished, I'm more angry. I decide to take you outside and let you go. As I get up, I ask you--did you also wish that you could float away like a balloon into the sky, since you were so upset you had to spend your birthday alone with me? Yes? Well, I guess I'm here to make your birthday wish come true. I don't need a balloon boyfriend. Byeeeeeeeee.............

I had a lot of fun with this one! It its my first audio inflation clip This one is very realistic and fun with the extensive role-play, context and storyline, hope you enjoy!
