My father remarried, and as an only child, I gained a new mom and sisters. Under one roof, my pubescent penis is excited by the sight of their defenseless panty flashes and boings. 'We're family, even though we're not blood-related,' they say. It seems my insatiable penis is welcomed, as I've been taught about the female body. Even my mother joined in, making splashing sounds as my sisters toyed with my penis.
