Cum later (so mom can watch).

As much as it would feel good to cum while watching your mom get off in the shower, you decide to hold it back. You don't want to waste a drop of your cum where nobody can see it. There's no reason to. But there is a way to further your mom's lust for you and have some fun while doing it. You watch her for a few more moments until she finally cums, moaning your name. You grin and carefully shut her door. You pull your pants back up and head back to her room.

You quickly get into position, sitting on your bed. You leave your door open enough so just about anyone could peek in and see you. You slide your pants down, revealing your still hard dick. You go to your computer and pull up a picture of your mom. It's a picture she took a few years ago of herself in a bikini at the beach. You've cum many times while looking at it. This time, you're not keeping it a secret.

You start to slide your hand up and down your throbbing cock. You're horny as fuck. But you don't want to cum too early. You want to be sure your mom is watching. You tease yourself for a little while, just keeping yourself on the edge.

You start to pick up the pace as you hear footsteps approaching your door. You start to moan a little to semi-alert your mom of your current state of mind. You hear her footsteps slow. It almost sounds like she's trying to approach your door without you noticing.You hear her give out a gasp and a very soft moan. She's obviously seen you by now.

You start to speak a little so that she can hear you but so that it doesn't seem like you're actually talking to her. "Oh, Mom," you say. "You're so fucking hot. God, it's so wrong, but I wish I could just... just take you and throw you on the bed and fuck your brains out."

Your hand is a blur on your dick. You're trying to keep yourself from looking at your door. You're staring at your mom's picture on your computer.

"Your breasts are perfect. I bet they would feel great wrapped around my cock. God... And your ass. I bet you just love being spanked. I want to be the one to give you that. I want to give you all the sexual pleasures you've been missing... Let me fuck you, Mommy. I need to fuck you. I need to ride you from behind like an animal. I fucking need to split you in two with my dick."

You go quite, moaning and grunting as you finally explode in big spurts onto the floor. You hear another gasp from your mom as this happens. You ride out the orgasm, moaning your mom's name the whole time. Finally, yousit back. You hear the light touch of your mom closing the door to your room. You smile to yourself at a job well done. You start to clean up your mess as you try to decide what to do next.

Well, your sister should be home soon, obviously still pissed off at you for her humiliation last night. Should you bother trying to talk to her? Maybe she'll just forget about it eventually. Or maybe you're perfectly happy pursuing your mom instead of your sister for now. Or maybe she IS worth pursuing? It's time to decide.
