It's called google, sweetheart. Check out the world of kink. We're here, we're freaks, get used to it.

It sounds like you're both interested in experimenting. Maybe check out online ads and see what's going on in that "world" first.

If you're both attracted to your friend, talk to her, draw her out. She knows a lot. Have a nice, sensuous dinner with wine and play some nice music. PF would recommend jazz.
