Family Ties/Look in on Jacob and see what he’s up too.
Frustrated and horny, you march up the stairs, barely stopping yourself from stomping like a child having a tantrum. You pass Jacob's door on your way down the hall, thinking nothing of it seeing as you could tell his light was off. But you hear a sound from his room, a soft breathy moan that makes you stop. You walk back to Jacob's door and realize there's a dim white light coming from under the door, not unlike a computer monitor in a dark room. Listening to the door, you hear Jacob breathing hard. To your surprise, the door slips open just a little. The latch must not have caught when he went in earlier. Curiosity gets the better of you and you peek in.
You see Jacob sitting in front of his computer, shorts around his ankles, arm pumping fast, headphones over hie ears. He's staring hard at the screen, watching a video you can't identify from here. You bite your lip as you watch your son masturbate, filled again with a hunger for a nice hard cock. Timmy may be your preference, but you've had fantasies about Jacob, too. And right now, you're desperate enough for cock that you're strongly considering trying your luck with your eldest son.
