A sweet-niece gasp made an uncle chuckle:
Took his finger to the second knuckle!

As two more digits broached junior-high cunt,:
That sweet-niece "gasp" turned virginal "grunt."

That throat of thirteen was crooning and humming,:
Once young clit got its first thumb-strumming

Seventh-grade titlets were avidly suckled:
As niece clawed madly to get him unbuckled

Avuncular manhood sprang into view:
While hairless quim oozed a welcoming goo

Lodged at her entry, the lust-hardened nut:
Prepared to give sweet niece her first-ever rut

Lined up behind it, eight inches in all,:
Uncle's proud shaft plotted innocent's fall

(Lest last-minute virtue deny coupling untoward,:
Uncle wasted no time in driving hips forward!)

Hymen now tattered, allowed him to pass,:
But just to be sure, he clutched at her ass

(Finding a rhythm, he picked up a pattern,:
Turned pussy untried to that of a slattern.)

Driving in deeper, he nudged at her womb:
Colliding with cervix, boomity-boom

(Prior reluctance was given the lie:
By the sound of her middle-school "Don't stop now!" cry)

And then she was lost in shocking cunt spasm,:
A simpering schoolgirl in deep-stroke orgasm.

Satisfied shortly was uncle's own need,:
Blasting her belly with relative seed

Now she's in love with mom's older brother:
(Who just knocked her up as her own cousin's mother!)
