Family Ties/Stick your cock in her mouth.
You stand and your crotch lines up perfectly with your mom's face. Still asleep, her mouth half open you slip your throbbing dick in. You don't even have to thrust, you're so close to cumming the sensation of her tongue on your cock pulls your hot wet cum straight from your balls. You only get your dick halfway in before streams of your jizz start filling your mommy's mouth. Your cum is dripping out of her mouth by the time you finish. You regain control of yourself and you stand with your satisfied dick still in your Mom's mouth.
You pull back to take your cock out, but as you do your mother's lips wrap around the head and she starts to suck on it. "OH MY GOD!" you think to yourself, your whole body goes rigid. Your mother slowly raises her hand to hold your dick while she sucks, as she opens her eyes she looks up at you and smiles. Taking her mouth off of you she swallows your massive load of young cum and tucks your dick back in your boxers.
With her hand she turns you around and gives you a light smack on your butt to send you off to bed. You have no problem falling asleep now.
The next day you wake up and get ready for the trip.
