Grandfather! Let me suck your eggs, I want you to fuck me!

The old man is no longer to have sex with young girls, the old man barely feels that his cock is alive and cares little if he fucks or not. His granddaughter is an incestuous sow that grew up with him and has always liked to be fucked by the old man. Since she was a young girl the dog has had incestuous sex with her grandfather, being this the only one who has penetrated her and made her a woman. Now that the old man is over 80 years old, the dog still likes the old man but he does not perform as he did a few decades ago.
