Encourage this development

Speechless you watch as your best friend sucks her father's dick, a dick that was just inside you.

This is so fucked up, you think, and I love it.

Emily's head starts bobbing hard on her dad's dick, you can hear Mr Fowler grunting behind you with each time his daughter gets to the bottom her motion.

"You like your actual daughter sucking your cock Daddy?" You ask him.

"Oh fuck, yes."

"Say it." You push him.

"I like feeling my daughter sucking my cock." He replies, strained.

You get off of his lap, and get down next to Emily. Going lower you start lapping at his balls.

As you take one of his balls into your mouth, you lock eyes with him and try and give him the most seductive look you can. You bring one hand up on to the top of your best friend's head and gently encourage her to go further down her father's member.

Gently tonguing his balls for a few more seconds as you guide the fellatio, it then occurs to you.

"Is this all you want Daddy?"

He looks at you, his expression changes to something steely, harder than it was before. You have the feeling that control is about to change.
