He tries to lie, but you know the truth

"Emily" he tries to sound convincing "I swear that I would never think about my daughter that way."

"You know what I learnt about men, dad?" you make a stop forward and he makes a step backward "That they are liars. But they have one thing attached to them that can't lie."

You make another step forward and he makes another step backward. This routine repeats itself until his back touches the wall. You quickly seize the opportunity and touch his crotch. It is the least surprising thing in the world, he is hard as a rock.

"Just like I thought. You can try to lie, but he can't" you say.

"Emily listen..." he starts, but you don't listen. Instead you get on your knees and take out his cock. It's pretty big. You touch it delicately.

"Emily" his voice grows more and more desperate "I have...really dark thoughts about you. But I...always managed to stop them. But if you do that...I don't know if I..."

"I want it" you say and slowly stroke his cock. Then you give it a little lick. You hear a moan.

"You don't understand. If I was dreaming about having regular sex with my daughter it would be fucked...up...enough" you take him into your mouth which causes him to stop for a moment, but he tries to continue "but I had dark fantasies...about you, if you keep continue..." you use your tongue which causes him to stop again "...I won't be...I can't"

"It's okay, daddy" you take his penis out of your mouth and smile "I know that you would never really hurt me."

"Don't be so sure" he warns you.

Still smiling you stroke his cock a few times and then tease it with your tongue "I'm not afraid" you declare.

"Emily" somehow he manages to make his voice sound strong "I'm barely stopping myself. Are you sure you really want it?"
