Not at first

Your dad is unaware you are watching him. But as you lean against the hallway wall and slide your fingers over your slit, heat builds and you close your eyes. Seeing cock does remind you of Alex's cock as you start to dream of him fucking you instead of your dad. As you become more aroused, you close your eyes and let out a low moan without thinking.

You don't see that your dad hears you and turns toward you. He sees you not watching as slowly walks out of the bathroom toward you. He starts to stroke his cock getting it hard as he stands right in front of you in the hallway.

"You know Summer, I knew you were a slut but hot damn. You just had to speak up if you wanted more of my cock."

You're eyes shoot wide and you see your dad hard in front of you, "W-wha?!?!"
