“Like a penis, at least before circumcision, the head of your clitoris is covered by a hood, or prepuce, which is similar to a man’s foreskin. When sexually aroused, the clitoris becomes erect and the prepuce retracts and exposes the clit’s head, just like the foreskin does on a penis. The hood is connected to your inner labia and when you fuck, your pussy-lips pull on the hood, causing it to open and close over the head of your clit, stimulating it.”
Ron tenderly caressed the area around Amy’s clitoris, then gently pressed down on either side. The bright, pink nub of her clit, glistening with moisture, protruded further from the darker skin of the surrounding shroud of its hood. He pressed and released several times causing the girl’s clit to repeatedly emerge from, and retreat back inside its hood.
After a few moments, Amy groaned and her butt squirmed. Her clitoris no longer retracted completely into its shroud when he released the pressure on her labia, and, instead, remained slightly exposed.
“Ahhhh, yes…” he murmured. “See? When your clitoris becomes fully erect, its tiny head emerges from its hood and it can be stimulated directly.” Leaning down, he touched the extended tip of his tongue directly to the glistening pink nub of his sister’s clitoris.
Amy gasped and her body jerked. Ron gently flicked the tip of his tongue back and forth across her exposed clit-head a few times, then swirled it around and around its shrouded stalk.
“Oooooooh…ohhhhhh…ooooooh…” Amy moaned, her ass writhing, as her brother’s tongue tenderly caressed her clitoris.
After a few moments, Ron raised his head and looked at his sister, smiling. She groaned, and her tense and trembling body relaxed as his tongue left her clitoris.
Ron sat up straight, feeling his cock throbbing insistently. He took a few deep breaths to settle his own rising passions, then, after a moment, he began to gently caress his sister’s erect clitoris with the tip of his finger.
Continuing in his faux professorial voice, Ron said, “While the penis has several functions, such as: passing urine, delivering semen into the vagina, and for display, like those south sea islanders I mentioned, the clitoris has just one: providing pleasure to the woman during sex.”
“Ummmm…” Amy purred, smiling. “There’s another function of your penis that you didn’t mention!”
“What’s that?” he asked.
“Providing pleasure to a woman during sex!” Amy giggled.
Ron chuckled. “Oh, yes, that is, indeed, a major function of the penis, as well! My favorite one, in fact, now that my beautiful sister has introduced me to it!”
They were both quiet for a few moments, as Ron gazed down at his sister’s lovely little pussy and she stared intently at his upthrust erection.
“Whew!” Amy gasped, her ass squirming. “I’m really appreciating that ‘display’ function you mentioned, Ronnie. Looking at your cock, standing there, all stiff and hard…it’s making me feel all fluttery deep in my stomach…and my pussy feels all warm and squishy.”
Ron looked up at her and smiled. “I’m glad to hear that, Sis! I understand that a lot of women don’t like to actually see a man’s penis…that’s why they won’t fuck with the lights on. They don’t want to see it, they just want to use it!”
Amy laughed. “Not me!” she assured him. “I love looking at it…and how it makes me feel when I do!”
Ron smiled again. He looked back down. “Wow! I can see what you mean…just look at that!” He touched her hand to indicate she should look at herself in the mirror. “Look at how wet your pussy is now!”
Amy adjusted the angle for a good view of her cunt and gasped as she saw how her pink inner labia glistened with her sweet nectar.
Ron touched the tip of his finger to her vulva and tenderly caressed her moist vulva. “As I was saying,” he said, resuming his lecture, “your clitoris is very similar to a penis. It has a head, and a shaft…except that in most women you can’t see the shaft because it’s inside your body. I understand that women, like men, are also ‘showers’ and ‘growers’, but the visible effect is reversed. While, I believe, most men are ‘growers’, I think most women are ‘showers’, meaning their clitoris engorges without significantly growing in size, except to push out its head a little bit. Some women, however, have a clitoris where the shaft actually extends a little ways out of her pussy when it gets erect…almost like a little cock!”
