What's the highest age until it's disgusting?

Normaly until 40, older is okay if shes still nice.

This.

This old

I think 14 is the absolute max. After that their breasts start to develop.

oh my.. ahaha.. that made me lol..

well i think 14.. too.. oh my..

umm once you hit 50, goodbye

The mid 40s I would say.

Obviously, this would be a on a person-to-person basis... But in general I'd probably say somewhere around the realm of 50 or above.

I would have to say it does depend on how they look more then age but at the same time if i saw someone attractive and someone else said they were like over 50 i would take my comment back!! When it comes to anime and hentai it only depends on how they look ;)
