Sam (short for Samantha) was lying in bed, peering through the half-open bathroom door where her husband was toweling himself off after a shower.
She had never given much thought to penis size. It was his interest, and his prodding, that had caused her to rethink her stance on the importance of the male anatomy. She was quite "vanila" before meeting Alex, but he had quickly brought out her wicked side.
Sam's last boyfriend was large. He didn't shut the door when he showered, like her husband. Quite the opposite, he'd purposefully parade around the bedroom and bathroom nude. At the time, Sam was turned on and impressed by his confidence, but she never connected the dots. She had only recently realized just how important penis size can be to males (and to so many of the women in their lives).
She kept staring at her husband, catching flashes of his penis through the crack in the door as he moved about. Alex's penis bobbed slightly as he walked. It was maybe a half inch long, and stuck straight out like an acorn. She thought back to her ex, and how his cock had hung down several inches. It had some real weight to it, and swung when he walked. She'd never measured her ex, but she could estimate him at about 4 and a half inches soft, and maybe seven or eight inches hard.
