Lesbian Stepsister Uses Stepbrothers Cock to see if She is Bisexual

Hey. Hey. What are you up to? I'm just relaxing, I just got home, you?

What's wrong? Me and my girlfriend had a fight. Why? Because she wants to tell me that everyone is a bit bisexual.

And I said there's no way that I'm bisexual. Why, don't you think you could like a cock?

I highly doubt it. Well, I'm kind of on her side, because how would you know if you don't give it a try?

I suppose I have never tried it, so I can't really be the judge of it.
