Randy was shocked, “Fuckkkk,” he sighed as her throat massaged his cock. Randy got another chill from how good it felt and fought to control the urge to fuck her right then.
Once he got control of himself, he looked down at the blonde who was now enthusiastically taking all of his cock down her throat repeatedly, “No gag reflex, oh my word, you are an angel; now, look at me while you’re sucking my dick baby girl, and don’t take your eyes off me.”
With that, Gabbie took her mouth off his cock, and smiled giddily as she sucked saliva back into her mouth. “Did I do that right?”
A leering smile overtook Randy’s face, “Oh yes.”
“I done it before and the guy came right then, so I didn’t know if I was doing it right or not since it was so quick,” she told him as she gently stroked the monster in her hand.
“You’re doing it just fine Gab, now get back to it,” and he tapped his hardness on her forehead.
Opening her mouth on approach, she guided the head in and sucked it down to the root in one fell swoop and then took her hand away and placed them both behind her back in a submissive position, though Randy doubted she knew that.
With her eyes never leaving his, she began going faster and faster. He was fascinated by the flare of her nostrils and how her lips maintained hard suction every time she backed off his cock. When she buried it to the root, she would move her head slowly from side to side to force him even deeper.
It occurred to Randy then that she was trying earnestly to impress him.
After the third time she went completely down on him, he held her there with his hands until the first sign that she needed to breathe and then let go so she could work her way off, nostrils flared again.
Gabbie backed off and gasped for breath, long strings of saliva drooling from both her mouth and his dick. In her eyes was the look of someone who had just discovered their true purpose in life, a look of wonderment and acceptance at an unexpected discovery.
Randy was fascinated by this and the fact that, while Halley had to learn to take his cock all the way down, her little sister had done it on the first try with no effort. ‘Amazing,’ he thought, ‘a freak of nature.’ Little did he know at the time.
He bent down and took both her cheeks in his hands to kiss her passionately, intertwining his tongue with hers.
Another difference between the sisters dawned upon him as they kissed.
Whereas Halley’s tongue was long and narrow, almost reptilian; Gabbie’s was broad and fat.
“You rest right here a sec and let me get some things,” and she relaxed on her butt with her legs folded up under her, saliva still dripping from her lips and chin, as she played with her pussy while he went to the storage room.

When he returned, he found her standing at an opened cabinet and examining vacuum suction tubes. He walked to her right, massaged her nearest ass cheek with his left hand and asked, “Curious?”
“What are they for?”
“Same principle as the suction cups, but you attach them to a vacuum pump with a hose, like the milker, and you have much stronger suction, but it’s constant instead of pulsating.”
Her eyes grew wide, “Oh,” her voice trailing off.
She was the big-eyed baby girl, just learning about the real world that she didn’t know existed as she stood there contemplating what she held in her hand with her mouth hanging open, her face full of wonderment.
He walked to a far wall, and she turned holding two different shaped tubes up in her hands, “What’s the difference?”
He turned to see what she meant and smiled, “The flat-ended one is for smaller nipples and the flared-end one is for big ones.”
Still holding the two tubes in her hands in front of her, Gabbie looked down at her own breasts and the then back to Randy, “Cool!” she smiled.
“Put those back and come here.”
She did as instructed and came over to the rig set in front of a wooden plank wall. It was made of black steel piping and the most prominent feature were two pipes about four feet off the floor that stuck out horizontally in a V-shape from two pipes that ran floor to ceiling.
