The Daughter-in-Law's Secret

I peeked at my son and daughter-in-law having sex, and her moans got me so hard I couldn't stand it. It just so happened my son left for work, leaving only me and that slutty daughter-in-law at home. The slut wasn't wearing a bra today, deliberately teasing me to fuck her. While cooking, she got herself soaked all over, so I steeled myself and went straight for it—and it turned out she'd been waiting for me all along. Taboo role-reversal mature slut. My son couldn't satisfy his wife, and she'd been lonely for a long time. Now that she's got her father-in-law's big cock, she wishes she could be fucked by him every single day.
