I want to make sure my son's big-breasted wife pregnant

My father-in-law hopes to see his grandson soon, but his important son is immobilized. In a frustrating situation, my stepfather, who is extremely sexually, gets an erection! I give my wife a boob massage to make it easier for her to get pregnant. Her father-in-law's actions escalate, and she cums inside her in an attempt to seriously impregnate her son's wife! "I want to get pregnant with my grandson," and my wife has been moistened by the aphrodisiac and has had a continuous creampie sex! My crazy stepfather grins when he thinks he can see his grandson with this...
