as a adult lol.... and hanging out....
any suggestions???

You'll have to be a little more specific.

You are probably asking the wrong group for suggestions on what a gorgeous 20-year old would enjoy doing.  

What sort of activity are you looking to do?

It's getting harder and harder to find things that are uniquely NYC.  With every passing year there are fewer and fewer things here that you can't find at home in LA.

Re: how about a little hot porn star girl/girl fun with me ?

You can come play with me ... mmmmmm ! ... and just out of curiosity, would any of you guys out there ever be into coming to watch a hot live girl/girl porn show ?
