"Did you ever see Father's cock," Janet asks. She's just told you about how she saw him in the shower.
You shake your head. "I don't think it'd be that long," you say. "Mine isn't all that big, so I expect most grown-ups will be bigger than me." As your speaking, the object under discussion is sliding in and out of your sister's slippery little cunt. She is on her back, with a pillow under her bum and you're kneeling between her legs.
She giggles as you thrust in as far as you can and hold it there so that you won't cum too soon. "It was hard enough to stretch my mouth around Mr Johnson. I can't imagine what it would feel like to have a huge cock where yours is."
She stopped speaking then because you had slid your hand down between your bodies so that you can get your thumb on her clit. As you feel her climax beginning to build you speed up your fucking action and when her cunny-muscles start clamping down, your balls begin to pump and all either of you can say are moans of pleasure.
Later on, as you loan your back with Janet's head resting on your chest, she tells you about going to visit Susan's uncle. "We are supposed to be going to look at some books, I think they might be more to it than that. Her Uncle Jim has been fucking her for years, and his sister, her mother. She thinks it's possible that he might actually be her real father."
"Are you sure about this," you ask, rolling her off and sitting up.
"Susan says he's okay and we can always leave if we are not happy."
