Go downstairs for breakfast with your parents

As you stood up the plug shifted inside you. It wasn't so bad standing, although it was still filling you up in that way that made your cock harden. Your dick was still sensitive and kind of sore from your orgasm just minutes ago but even so you were half-hard as you pulled on your pants. Adjusting your crotch to hide it, you headed down the stairs.

Every step down made the plug grind against your most sensitive spots and by the time you hit the bottom your cock was rigid and throbbing. You lifted your hard-on flat against your belly and then trapped it there with your waistband, hiding it under your t-shirt. As you enter the kitchen you notice it's only your parents present and you're secretly glad, you're pretty sure not everyone of your family members will be as ready to fuck as your dad was. Speaking of your dad, he's sat at the table with a smug smile on his face and he makes a teasing kissing expression at you when your mom turns to look at you.
"What took you so long?" She says, looking confused and a little irritated "Your brother and sister have both been and gone."
"Sorry Mom, something just..." You look over to your dad "Something came up."
He holds in a little laugh and your mom decides not to ask further.

As soon as you sit down you feel the plug move inside you and you stiffen in more ways than one. Your discomfort and confused arousal isn't helped when your dad puts his hand on your thigh under the table and starts massaging your soft flesh through your pants. Trying to make small-talk with your mom is almost impossible under the circumstances, especially because all you can think about is how you're going to fuck her. Your mind returns to the original plan, before you ran into your father. You were going to **** yourself on her, give her ****, make her enjoy it. That could be a lot easier to do if your dad was in on it, judging from the way he pounded your ass he liked it rough, would he be so against you doing the same to his wife?

When she stands up to put the dirty dishes in the machine your dad leans in towards you and whispers "So how did you deal with all that cum?"
You whisper back "There's a plug in my ass, holding it all in." You start to grind your butt against the seat slightly, driving the plug deeper "It feels so good..."
Your dad smirked "I can see that." and he pointed to your belly.
You looked down and whispered a curse as you noticed a little patch of sticky precum on your t-shirt where your waistbanded dick lay against your belly.
