She never dreamed his cock would be this large. She can feel his pulse beating in the veins of his cock. Occasionally she rinses the soap off her hands in the pan of water and return to his cock to remove excess soap. She slowly moves her hands up and down his shaft. She knows she needs to finish the bath, but doesn’t want it to end. David doesn’t want it to end either.
Lucy unconsciously starts moving her hands faster and faster up and down his cock. She has her eyes closed and appears to be off someplace else. David feels his balls start to churn and cum starts racing up his shaft. It happens so fast he doesn’t have time to alert his sister; and without warning his cum starts spurting from the head of his cock. Without thinking Lucy quickly leans forward and captures the head of his cock in her mouth; just like she has done so many times for her husband’s orgasmic bursts. When she does realize her mistake it’s too late. She can’t take her mouth away because David keeps on pumping streams of cum from his cock. She starts gulping every drop and when he finally stops, she licks and sucks the final few drops from his cock and then wipes her mouth with the back of her hand.
“I am so sorry, Sis. I wanted to warn you, but it hit too fast for me to alert you.”
“God, your cock tastes good, Big Brother. Why didn’t you let me do this when we were teenagers?”
“I wanted to, but I was afraid you would tell Momma and then Daddy would have beaten the hell out of me.”
“If only you really knew how many nights I laid in bed wondering what you cock would feel like sliding deep into my pussy.”
“What’s keeping you from doing it right now, Sis?”
Lucy squeezes her Brother’s cock and then leans forward and kisses the head of it before swirling her tongue around the end once more before stripping naked.
Then Lucy slowly moves up, straddling her Big Brother’s waist; taking care not to hurt his shoulder or knee. He can see her crotch up close and notices only a small strip of black hair between her legs. He takes his hands and strokes her body up and over those wonderful breasts then moving to her face now hovering over him.
