Sniff your wife's girl-sweat on your pillow.
From Create Your Own Story
You bend over and inhale your wife's gorgeous scent. It doesn't smell like regular, stinky man sweat. It's different. It smells so good, a cross between her own aroma and her girl-sweat. You lift the pillow up onto your face and fall on your back, sniffing it as much as you can. Your dick is as hard as iron.
