Convincing your mom to have sex with you was easy. She was such an oblivious dumbass. You just had to lie about some new study about how incest was actually good for the female body. Now she can't stop bouncing on your dick for 5 hours a day to feel young again~
Grandma's don't be afraid to build a special relationship with your granddaughter. She's the next generation of incest lovers. You'll both feel incredible lying naked next to each other. Realizing the love between you.
