Looking for a story. I literally just read it about two days ago and now can't find the damned thing. It is a story about a man cheating on his wife and how he and the girl he is cheating on his wife transform. Now, from what I remember, they didn't take on full animal form. The girl had cat like qualities, while he had dog like qualities. There was a lot of focus on the girl's sensitive nipples. I couldn't remember if she had multiple. Lastly, he receives a message to return to his wife the next day. Following this instruction, both he and the girl do so. Upon arrival, the wife welcomes them and asks that they quit their jobs and live their lives with their transformations and remain loyal to her. If so, they can all live on having sexual relations among the three of them. A lot of a paraphrasing, sorry. I swore I read it on Literotica! This is aggravating me to no end >.<. Feel free to ask more.

ps - the sensitivity of the girl's nipples would cause her to almost instantly climax.
- The story was told from the perspective of the man.
