The Zoologists/Watches
Lisa watches through the crack in the door. She slips some fingers into her pussy and start masturbating.
She matches her strokes with the speed of her dad. Watching them fuck, it doesn't take long before she comes to an orgasm. She moans load.
David looks at Lisa and cums deep into Page. At that moment Page Orgasms, She looks at the door and also sees Lisa.
Lisa notices they have seen her and runs back to her room, leaving behind a small trace of liquid where she had her orgasm.
...
Later Page walks into Lisa's room.
"What you saw was for your benefit"
She smiles when she says this, making Lisa smile.
"I know what dad did to you and he won't do it again do you understand?"
Lisa nods her head.
...
A few months roll by and every now and then Lisa hears Page moan in her room. When this happens Lisa opens the door a bit and watches. Sometimes its the dog and others its dad.
Page knows Lisa watches and puts on a show when she does.
