The Experience of a Lifetime by Jole1038
Nice multipart unbirth story by Jole1038 on DeviantArt following Ellen and her husband Mike. They often try some freaky things in bed and during a weekend, Mike makes a suggestion Ellen only partially listens too. The next morning, Mike actually tries this out and Ellen gets positively surprised by the pleasure it causes her.
This story also makes use of a corset again, making it even better. Especially near the end, there’s some awesome Hidden in plain sight stuff going on.
