You are Karkat.
God damn, you are having too much fun with this. You don't feel guilty at all. Your hand is running up his shirt and you're fucking enjoying yourself. You lick your lips before they make contact with the guy your with.
Yeah. You are with him, when you know you should be with John right now. But you can't help yourself, and he isn't stopping you either.
You feel his hand casually slide up your thigh, and you smirk.
You're kissing the guy.
You put your arms around his neck and he has his on your waist. He licks your bottom lip, and he wants in. You give him the ok, parting your lips slightly.
He takes the opportunity and your tongues are having fun with each other, and now both of your hands are exploring each others' bodies.
You really can't stop. Even if you tried.
