Ask for a blowjob.
From Create Your Own Story
You decide you want a blowjob from your mom, so you ask her, "Could I get a blowjob?"
Without a reply she just gets down on her knees in front of you and grips the top of your boxers with her fingers and slowly pulls them down. Your penis springs free and she sees all 7 inches of your penis. "Wow. I'm impressed Jacob, I didn't know you were this well endowed." Before you can reply she takes your dick into her mouth.
Your mother has only given you head so far, but is the greatest feeling you have ever had in your life. You just stand there moaning, trying not to explode into her mouth. She looks up at you and she can tell that your about to explode. "Come on Jacob, you haven't really helped me like you promised. You don't want to disappoint your mom do you?" your mom says, you reply will breathing heavily, "No, definitely not."
Then she decides to take your full length into her mouth and you feel your dick hit the back of her throat. She holds it and her tongue just goes around the bottom of your dick and you can't take it anymore.
You start shooting your load down her throat and she just swallows each wave as you shoot your largest load ever.
She then walks over to the bed and lays down, saying "Now, its your turn to help out mommy."
What do you do?
