.....having fantasies about my (female) best friend who I am starting to fall for I think. I'm not sure if when we'd kiss I'd be turned on, but when I think about her lying next to me in bed and we're watching tv or something and she started to f*nger herself and start moving faster and stuff, I really get turned on. and I would then like to take over either with my hands or my tongue.

any help here? haven't experienced this before, I am 21.
