**PART FIVE**
When I first sniffed Julie’s panties in the car, I considered the smell euphoric. When I tasted her fingers immediately thereafter, I recalled thinking it divine.
Buried completely between her thighs and lashing at her femininity with my tongue was nothing short of eternally blissful.
Instead of fumbling about clumsily and hoping for an adequately rated performance, I felt almost driven with confidence and purpose. Julie gnashed and gyrated in time with my movements. I licked her left then right, while she swayed her hips right then left. Our shifting bodies oscillated in perfect synchronicity.
Desperately wanting to glance upward, I fought the urge and concentrated on rocking side to side rhythmically with Julie. No matter how I moved, she seemed to anticipate every gesticulation. She met every twist with a reciprocating turn. For each one of my turns, her body matched me with the greatest of ease.
I had never felt such perfect compatibility with anyone before, sexually speaking, or otherwise for that matter. I bobbed and she weaved. I probed and she received me. She rocked and I rolled. There was no end to the dance.
In an attempt to drive her over the edge, I pressed my tongue firmly against her clit and licked upward repeatedly. Every stroke applied equal amounts of force and my sister began to groan in satisfaction.
Giddy with excitement, I began to lap and flick her maidenhead with renewed vigor.
“Slow down a little,” Julie breathed heavily. “Not so fast.”
Her fingers scratched at my skull and twisted my hair into knots.
I slowed the pace of my tongue, but retained sufficient influence against her engorged clitoris.
My efforts did not go unrewarded. With her direction, I doggedly gave the best effort possible. Julie began to wail in ecstasy. My cock quivered with triumph.
As her body writhed against my face, I felt her arch upward. Sliding a hand under her ass, she clenched her cheeks tightly. I could almost cup her entirely in one hand.
Dipping up and down as my tongue explored the most sensitive parts of her labia majora and minora, the muscles in her butt flexed from firm to flaccid. In a flash of either sheer brilliance or ultimate stupidity, my hand retreated slightly as she rocked softly against the bed.
When her ass tensed once more, I lashed at her clit once more. Relaxing slightly with both cheeks in hand, I made a move hitherto unfamiliar to me. The very moment before she was about to tighten again, I poked an exploratory middle finger into her asshole and pushed forward.
Julie arched her back and grasped the sheets. Her hips trembled. Her pelvis flinched dramatically. The dynamic influence I maintained against her swollen cunt, coupled with the newfound dominance, rendered her speechless. She gasped and struggled to produce nary a sound.
Feeling prideful of my efforts, I opened my eyes and approached her slowly. Lifting my head, I maintained my finger in place, but slid the other hand up her thigh, moving toward her breast.
She grasped my hand and stared at me with desperate intention, breathing laboriously. Her acute grip spoke volumes. I had struck a nerve. Perhaps more than one.
As she composed herself, my finger withdrew from her dark pocket. Only then did she begin to laugh, albeit somewhat maniacally.
“Oh, dear brother,” Julie exclaimed, gulping air eagerly. “I never would have expected you had that in you.”
Intoxicated with unfamiliar circumstances, I become someone else entirely. I was completely out of my element, as well as my mind.
“You never expected *me* in you, did ya?.”
“Oh, but I did,” she replied. “So much so, you wouldn’t believe it.”
