My husband told me to watch his father and I obliged. I begin to clean for him but I start to vent about my husband's infertility and how badly we want kids. But unfortunately we are unable to no matter what. I feel like my womb is going to waste and I throw all my emotions towards grandpa. Then I get ready to give him a bath and notice his huge bulge through his pants and I become stunned. I undress him fully and realized how big and erect his cock is and how swollen his balls are. I am sure if I get impregnated by grandpa my husband would understand - after all it is for us to have a family ;) custom
