Yes

Mike pulls down his pants and takes out his tiny cock, its only 3 and half inches when erect(something he has always been ashamed of) and starts to jerk off to Samantha.

She is lathering herself in soap and Mike can't help but think how wrong this is to jerk-off to his own daughter but she is just so damn beautiful he can't help himself, he decides to try to get a better look by getting a little closer and when he opens the door to the bathroom to do so the door makes a loud creaking sound.

Samantha's eyes dart up to see Mike beating his meat furiously and she gasps, Mike bolts out of the bathroom and runs to his bedroom in shame.

Samantha quickly finishes rinsing off the soap and dries herself off and gets dressed.
