Yeah, I'm going to suck him until the bitter, gooey end.

You agreed to provide sexual release for your stepdad, but in your head, you've only now REALLY committed to doing it. You slobber all over his dick and slowly move your head up and down, sort of on autopilot at this point.

You're on your knees in your living room blowing your stepdad. This is so weird, you feel like you're almost having an out-of-body experience, but you do what you have to do, slurping and sucking and bobbing your mouth up and down on his rock hard erection. It doesn't take long (at least it doesn't seem like long!) before he gasps and twitches and you realize you've made it to the end of the blowjob. You can tell he's just a few pumps away from blowing his wad.
