Tweak

He reached out, gave her nipple a tweak…
Her response not a yelp… more a squeak…
Well, it might have been worse…
She was tempted to curse…
WTF? OMG? What a sneak!

Harm minimisation

Big and ugly, as thick as her arm…
She took deep breaths and tried to stay calm…
So… her pussy might split,
But apart from that, shit…
Could it possibly do her much harm?

Mental struggle

She should maybe have screamed… to0 late… still..
She could struggle.. she might… well, she will…
Or else not… just stay mute…
Well, a root’s a damn root…
Just enjoy the vicarious thrill.

Quaint

So, American English is quaint…
Like for instance, this word they have, “taint”:
For that bit in between,
Not ass, cunt, not quite clean,
Though of course the distinction is faint. 

Beaver

Pa said  “Shoot! Damn bitch flirtin n teasin…
n wigglin her ass, stands to reason
She fancies some rootin…
Fergit about shootin,
Son, pussy’s in season!”

Frisson

Tall and handsome, and frightfully charming, 
A smile at once lewd and disarming
His whispered suggestion, 
Though out of the question
Enticing, as much  as alarming!
