My son’s wife’s big ass is spilling out from under her skirt, revealing her panties. “Dad, your pussy is the only thing that’s still going strong… I haven’t done it with my husband in months, so I can’t stop feeling horny.” I invite my father-in-law to my husband’s parents’ house with a shot of his panties, and sneak away from my husband to have sex in the hallway or kitchen… I visit the newlyweds’ house and satisfy the new wife’s insatiable sexual desire with a dick that’s harder than my son’s.
