>show her pics / vids from your younger days
>roleplay in bed and make her slowly more depraved
>whisper teases to her in public, about how that boy snuck glances at her chest or how willing any would be to touch her if she asked
>hire a neighbor kid to mow the lawn, dare wife to get changed near the window while he's outside
>let any nephew know that she *loves* hugs when alone, too shy to hug tight when around others
>sexy cosplay for halloween, you vet who should open the door each time to avoid risks and choose best candidates to be in awe of her body

>a decade or so passes

>you and your son are spitroasting your wife, she's soaked and moaning so much
>the sleepover for son & friends is next week
