Uncle sexy

Imagine a dilf, but someone you would never want to hookup with. That’s an uncle sexy. He is cute and attractive but too innocent to ever want to do anything with. Uncle sexy could also be an inanimate object such as a drink that in theory tastes good but you would never actually order in any sense ever.

“Wow! He was so cute but I just couldn’t fathom having sex with him. That would be weird. He’s too perfect to corrupt aka he’s uncle sexy”
