Dude, that is one BTF girl. I would do unforgivable things to her. UNFORGIVABLE.
Undeniable sexual god(ess). This person is BTF. This person redefines sex. having sex with this person is like having an orgy with ten or more of the hottest most sexually appealing and able persons you have yet to imagine while tripping hard on ecstacy. You don't know till you've done it. this is what has been missing in your life.
