Three years ago, mother-in-law passed, father-in-law got depressed with erectile dysfunction. Daily pills, workouts failed. He said: 'Don't want mom worrying in heaven.' His struggle moved me, couldn't stand by. To help mentally, agreed to his plea: bath together. In hot tub, his hard body rubbed my huge tits. Hands groped my stiff nipples, pussy dripped wet. Finally, his thick cock rock-hard! I spread legs, let him thrust into my soaking cunt, just 1 second. He groaned in ecstasy, pumped hot cum deep inside. Start of our taboo affair, wild pounding every night!
