Maybe if you paid more attention to your wife, you'd notice she'd been going to the gym. You seem surprised as you walk in the house, and see her doing pushups. Your jaw can't help but drop as she slowly strips off her clothes and flexes her rock hard muscles for you. In her heels, your 6'4" towers over you. Say thank you when she lets you take your cock out and stroke it to her muscles, and don't forget to clean up after yourself.
