Parents caught me sexting. [straight]

Last night my parents came home from dinner while i was texting with someone i met on this site. I was completely naked except except for my socks.

I tried to jump up and cover up but I wasn’t quick enough and they basically caught me red handed, so to speak.

They also discovered a huge wet spot on the couch that they weren’t too happy about and my dad said he “could smell my stuff.”

Then he spanked me. I don’t know how to handle this: I’m 21 years old. How do I tell my dad that he shouldn’t be spanking me anymore? Also, I feel like he may have been trying to smell me some more. Weird.
