Amy Weber went for a nap in the shade of the tree in her back yard. It was a hot afternoon, so she was wearing a t-shirt and shorts. Amylaid back against the trunk of the tree and quickly fell asleep. She is awakened by someone moving nearby. It is Sally, Amy's best friend. Apparently, Sally has tied Amy's arms behind the tree, and her t-shirt has risen up, exposing her sensitive pink belly. Sally is looking at the exposed flesh with interest, particularly Amy's puckered navel.
"What are you doing, Sally?" asks Amy. "Untie me!"
"Haven't you ever noticed me looking at your tummy any time it is exposed, even for a second? This is the chance I've been waiting for," said Sally devillishly. Sally lays on her side next to Amy, her face near Amy's silky belly.
"You have the cutest, sexiest bellybutton I have ever seen," cooed Sally. "Such a lovely large oval, with this rim all around it. And the puffy knot deep in the middle with its sweet little curlicues..."
Sally produces an artist's paintbrush with stiff brisrtles and begins tracing Amy's soft navel rim, around and around.
"NOOOO! I'm TICKLISH!!" squawks Amy. "Oh, I know, baby! You are in for one happy time." "No, please don't touch my bellybutton. Not my bellybutton..."
"Tickly tickly bellybutton!" teases Sally, as she begins to work the bristles into Amy's squiggly bellybutton knot.
"YAAAAAAAAAAAHAHAHAHAHAHAHAHA!" Sally cleverly runs the bristles under the umbilical rim, then lightly across the bubbles and grooves inside Amy's fleshy bellybutton. The charming little navel-button distorts as Amy tries to wriggle away, but she can do nothing to defend her innocent bellybutton as it gapes wide open exposing its delicate bumpy flesh.
"AAAAAAH! S-S-STOP! SAAA-LEEEEE!!" But Sally does nothing of the kind.
"Oh, look! I wish you could see this Amy, the little knot of your bellybutton middle folding and unfolding itself, wriggling around like it has a mind of its own!", and with that, Sally began forcing the brush bristles into the delicate creases and grooves of Amy's umbilical cord remnants, where there was flesh and nerves never before touched! Sally mercilessly worked the wiggly brush bristles down to the bottom of the bellybutton creases, tickling the virgin nerve-endings there.
"EEEEEEEE-HEEEEE-HEEEEE-HEEEE!" screamed the poor umbilically-tickled Amy. Slowly, Sally swirled the brush out from the forbidden territory of Amy's belly that it had invaded. But it was quickly replaced with Sally's dexterous tongue! Amy felt Sally's wet, slippery tongue tip carefully worming its way around inside her sensitive navel. It was surprisingly strong, slipping into tight umbilical clefts that Amyhadn't realized she had. And it TICKLED!!!
"SALLEEE NOOOO! HA HA HA HA HA HA" Sally's tongue could feel every little bulb and fold of her friend's fragrant navel, and wiggled it firmly into each little newly-discovered navel bit.
"Yum, Amy, your perky little bellybutton tastes delicious!"
"YAAAAHAAAAAAAAAAAHAAAAAAAHAAAAAAHAAAAAA!" Sally planted her lips around the tickled tummy-button and sucked as hard as she could. Amy's little bellybutton-knot bulged outward from her tummy and squeezed past Sally's pursed lips. Sally suddenly felt Amy's bellybutton cord pop into her warm mouth. She rewarded this pleasant little surprise by sucking and nibbling at Amy's extracted umbilical cord, her teeth gently squishing its rubbery firmness. Amy felt her bellybutton-stalk being pulled out of her tummy, a delightfully pleasant sensation of her hard navel-knot tugging at things deep in her belly.
"OOOOOOOOOHHHHHHHHHHHH!" sighed Amyas the oral manipulation of her popped-out bellybutton yolkstalk continued. Sally released her captive navel-toy, and admired the writhing belly-sculpture of Amy's protruding bellybutton.
"Look, Amy, your umbilical cord is showing!"
Amy looked down at her soft tummy and saw the short, stubby appendage of her sucked-out bellybutton stalk with its puckered dimple in the tip. Wet and slippery from Sally's mouth, it slowly folded itself back into Amy's belly and became an innie again. Sally gave Amy's cute bellybutton a quick kiss, then untied her and led her back to the house.
"My turn to tickle next time!" Amy said in a shaky voice, her bellybutton still tingling.
