Holly woke. Sophie was already up and getting dressed in a rush. "Hey Holly, just remembered I said I would help a friend set up a party. Got to be there in an hour. You can come and help if you've got nothing better to do."
Holly gets up and stretches. "Sure, sounds fun."
"Great. It's a street party, we've got to set it up, ready for this afternoon. Might even be balloons." She says with a wink.
"I didn't bring any spare clothes, mind if I borrow some of yours?"
"No not at all. Go find something to wear, I'll be back in a bit, Alice wants me to buy a few bits for the party."
By the time Sophie gets back Holly is ready to go.
"I bought some balloons, unfortunately couldn't find anything bigger then 11 inch. The last of mine are inflated in the bedroom, can't use them."
"That'll be fine, people aren't used to large balloons. Don't want anyone asking us awkward questions, do we?"
"Suppose not. You ready?"
"Yeah, let's go."
When they arrive there's a few people setting up stools and getting some music ready. Sophie goes and speaks to her friend Alice, then walks back to Holly. "Right we've got to put a banner up over there, then decorate the place with balloons." Sophie finds the banner and gives one end to Holly. "Take this end and tie it to that tree." She goes to the other side of the road and starts tying her end. Holly dose the same on her side. After the banner is done Sophie walks over to Holly. "Now for the balloons." She goes to one of the tables where she left them, Holly follows her nervously. What if someone notices that I'm getting turned on? She thinks.
"Hey Holly, relax. No one will find about our secret, they'll be too busy setting up the party." She takes her hand and Holly follows. Sophie takes one of the balloons and begins to stretch it. Holly feels nervous excitement as Sophie brings it to her lips and starts blowing. She just stands there staring while Sophie continues to blow hard, no one seems to notice how excited she looks and soon the neck begins to inflate. "Sophie!" Holly whispers, looking around to see if anyone is watching.
"What?" She replies in a innocent voice.
"Not so big."
Sophie locks eyes with her and blows hard again, the neck touching her lips now. A young woman approaches the table. Sophie quickly ties the balloon and throws it on the table.
"Hi, want some help?" The woman asks. She takes a yellow balloon from the packet and starts to inflate it. Sophie gives a red one to Holly before taking one herself. Sophie blows fast and has soon caught up with the other women. Holly puts a few breaths into hers, but gets distracted by the two girls. Their balloons are full now. The woman stops when the neck begins to grow and ties it, but Sophie doesn't show any sign of slowing down. Another deep breath and the necks bulging against her lips. Holly had forgotten all about her balloon as she watches Sophie struggle to put any more air in hers. The girl next to her realises what she's doing and puts her fingers in her ears. Sophie is desperately forcing in more air in. Holly wonders if anyone had noticed how turned on she is. Sophie blow hard again then the balloon finally pops, making the girl scream. "Whoops." Sophie laughs and grabs another. "Hey Alice, why don't you try? It's fun." She hands the balloon to her.
"Okay..." She replies looking nervous. Sophie takes the balloon from Holly's mouth. "Let me help you with that." She blows, quickly filling the balloon. Alice starts to inflate hers but stops when Sophie's is about to pop. She stares nervously at her as she forces more air in. BANG! It explodes in Sophie's face. She lets out a gasp then smiles. "Your turn Alice, keep going." Alice begins to blow again, Sophie watches her, standing close to Holly. She doesn't stop until the neck is completely full.
"Come on Alice, just a few more." Sophie encourages her. Holly can she her hands are shaking but she blows in another breath, struggling to keep it in her mouth. It still doesn't pop. Alice takes another deep breath and blows as hard as she can. Bang! The balloon shreds in her face, making her scream.
"Well done!" Sophie pats her on the back.
"That was awesome." She replies.
"Want to try another?"
"No, one was bad enough. I'm still shaking, I've never done that before." She then takes another balloon, a green one. "Guess we better keep going, the party starts in a few hours." She starts inflating. Holly whispers into Sophie's ear. "Sophie I'm about to orgasm!"
"Yeah I know, hold on." She whispers back. "Hey Alice!" She calls. "Mind if we use your bathroom?"
"No that fine." She replies, then goes back to inflating. Sophie quickly grabs two balloons from the packet. Alice doesn't seem to notice. She takes Holly's hand. "Come on, let's go." Holly feels nervous excitement as Sophie leads them to Alice's house. She finds the bathroom, pulls Holly in and quickly locks the door. She then grabs Holly's shirt and pulls her in, kissing her hard. After a few seconds she pulls away and puts a balloon to her mouth. She blows fast and after six breaths it's full, she ties it and throws it on the floor. Sophie gives the other balloon to Holly. "Blow. Don't stop till it pops. Not too fast though, we have to make it last." Holly takes it and blows softly. Sophie takes off Holly's shirt, then her own. Holly puts in another deep breath. Next Sophie starts pulling down her jeans. Excited Holly breathes hard into the balloon.
"Slow down, it's only 11 inch. Not ready yet." Sophie then strips off the rest off her and Holly's clothes and Holly blows again. She gently strokes Holly's pussy and another slow breath goes into the balloon. Sophie then grabs the other balloon and asks Holly to lie on her back. She then places it in between Holly's legs and slowly lowers herself onto it. Another slow but firm breath goes in. The balloon is full now and Sophie starts grinding hard against the balloon. Holly moans softly and blows again, making the neck inflate. Sophie is lying on top on her, the balloon getting bigger next to her face as Holly blows hard. The neck is pushing against her mouth but she puts in one more breath.
"Stop blowing, it's gonna pop. Keep it in your mouth though." Sophie is about to orgasm so she slows down. Holly can't help herself and puts in a small breath. The balloon is incredibly tight and almost completely transparent. Suddenly Sophie starts grinding hard again, the neck shooting out with every bounce. Holly loses self control and forces in a lungful of air. The neck seems to bulge around her lips then explodes loudly. Holly cries out and thrusts up against Sophie. The balloon between them can't take the pressure and pops. Sophie collapses on top of Holly. They lie panting for a few minutes before Holly pushes Sophie off. "I can't believe we just did that! Do you think anyone heard?"
"I hope not." She replies. "We'd better clean up then return to the party before we're missed."
After they had cleaned up, they both return to the tables to help set up the rest of the decorations. Alice soon finds them. "There you are! Could you help set up some party food? It's in my kitchen, just put it into some bowls and place them on the tables over there." When she goes Holly whispers to Sophie. "I don't think she knows. Imagine if she needed the bathroom. We could of been caught!"
"That was part of the fun." She giggles.
Soon the party is set up. Someone had tied up all the balloons and all the food was ready. Some music starts playing as people start arriving.
It is starting to get dark and most the people have already left. Holly and Sophie are about to leave when Holly hears something. The squeaking of a balloon. She turns around, there's three girls bouncing on balloons. One of them pops suddenly. The girls laugh. "Hey you two! We're popping the rest of the balloons. Want to join in?" Holly doesn't know what to do. She wants to join in but is scared someone will realise it's turning her on. Sophie makes up her mind for her. "Yeah okay, come on Holly." Sophie puts one of the balloons on a chair and slowly lowers herself on it. The neck comes out. "Come on Holly." She takes her own balloon and places it on another chair. She sits on it a little too hard and it pops right away. Sophie starts bouncing harder and soon her balloon bursts. She giggles and takes another balloon. This time she places it on Holly's lap and sits on it. The other girls pop theirs, Sophie has the last one. She bounces softly so the balloon doesn't pop. One of the girls takes a deflated balloon from the pack. "Let's see how big this'll go." She starts to inflate it. Sophie starts bouncing harder. The balloon is halfway full when the balloon under Sophie pops. She falls onto Holly but doesn't get up. The girl's balloon is full, the neck growing longer, when her phone rings."Damn." She lets the air out the balloon and answers her phone. "Sorry, I got to go." She says. The other girls leave. Sophie gives Holly and quick kiss and gets up. She picks up the deflated balloon that the girl left. "Come on." She says. They walk back to the car together. When they're in Sophie shows Holly the balloon. It's a blue 11 inch, Holly can see it's wet with the girls saliva. Sophie puts the balloon against her lips. "I'm gonna finish what she started." She blows in a breath. "Mmm, I can still taste her breath in it." She blows in another. Holly sees spit inside the balloon, it is going to be messy when it pops. She starts touching herself through her jeans. Sophie starts blowing faster. The neck is inflating rapidly, she doesn't slow down. The neck is pushing against her. She keeps going. BANG! Spit flys in Holly's face. She giggles and wipes it off. "Don't suppose you have any more do you?"
"No I don't think I do. I'll order some more when we get home. Want to stay the night again or should I take you home?"
"I think I'll stay the night, Dan won't know."
