I like 2 girls, these girls are best friends. Uh, here, simpler explanation: (sorry no pics)

Girl 1:
likes me a little
got her number but was grounded day after, and made her mad for a while...
liked her originally

Girl 2:
17 (my age)
dunno if she likes me
I like her too

i want to ask out one but which?!?!? girl 1 would probably be upset if i led her on and went for her friend, but i like them both.

what do i do?
looking for serious answers but will accept pit monkey comments for lulz.
