sex with my friend?

So I had a sleepover with one of my close friends. Not my best friend but probably my second closest. We had discussed masturbating before and I decided to show her porn because she had never seen it before. She liked the hentai but I wanted to show her some lesbian porn. She started asking very.... alluding questions like "would you ever do something like that" (I'm bisexual but she doesn't know) and things like "who would you do that with" I said "I'd probably only do it with you and my one other friend, but she is dating someone rn" and asked her who she would do it with. She said "probably only you". I'm totally down but should I actually ASK her or just allud to it a bunch or what? 
Please no hate I just want suggestions on broaching the topic, not to be called a faggot.
