There must be more out there, we've all done it, trying to think of things to google for just in case there's something more dirty and fun than those we know of. the feeling that "they're all enjoying this extra fun thing without ME". that feeling like on "old school", that even though you've seen most panties, there COULD be something new and exciting that you've never seen before.
so come on, let's list em...
I'll start off that list with
anal (not sure if that's even that dirty!)
voyeurism
bondage
bukkake (?)
large dildos
fisting
discipline
humiliation
cuckold
strapons
sorry if this has been done before....I'm lazy.....so SUE ME!!
