Another Story I forgot

Hey I'm really sorry to do this again but there is another story I can't find and hoping you all can help me out here. I thought for sure it was called "I married a balloon" but i can't find one like that anyware. It was about some guy who see's a pregnant lady somewhere and one thing leads to another until he is at home wit his wife and she gets a bike pump and has him inflate her. He goes overboard and pops her. Any help here? Sorry again and thank you.
