You are Gordon Freeman, and you were walking down the resistance base until you saw Alyx Vance and Judith Mossman in a lab together. They are also your girlfriends who loved you dearly. You have been secretly dating both of them for a while, and no one even knows about it, not even your buddy Barney Calhoun, your friend Isaac Kleiner, and even Alyx's father, Eli Vance. You were walking around the resistance base, where you found Alyx Vance and Judith Mossman bickering as usual.
Alyx: Maybe you should let me do the calculations next time, as well as install it.
Judith: Alyx, really. Sometimes I think you misunderstood me.
As they bicker, you crouch down on the floor and look at each of their butt, admiring how beautiful and perfect they look for both of them. Alyx and Judith are aware that you're staring at their butt but they don't mind or don't care as you've done this many times before so they ignored the fact you're staring at their butt because they never really minded and they don't care as you've always liked staring at their butt wherever and whenever you're with them.
