'You're right sis, this is fun!' said Rachel nonchalantly, then looked back at Paul.
The youthful aggressor paused for a moment, eyeing her dejected prisoner's expression as he breathed heavily through his nose, looking through teary eyes in disbelief at his girlish assailant's excitement.

Her eyes moved back to his throbbing red nuts swelling outside the tight grip of her small hand but still retaining their shape despite growing visibly larger from the girl's ceaseless ****.
Captivated by the malleability of these alien parts, Rachel curled the slender fingers of her free hand then slowly borrowed her thumb into Paul's frail left testicle intent on researching these foreign organs' resilience.

Paul's body tensed as his muscles grew taut in a vain attempt to endure this new focused source of anguish, his continuous muffled moan raised steadily in pitch directly proportional to Rachel's digging thumb.
The curious young girl, spurred by her victim's audible reaction to her experiment, moved her thumb in a circle with fascination, closely studying the pliability of the mushy boy-orb as it toiled to resume it's natural shape beneath her drilling finger.

Rachel moved her thumb to the other testicle, immediately noticing the relative firmness to its counterpart, which now appeared slightly larger after enduring a bout of isolated pressure.
Paul's tortured moans grew progressively more faint as he grew accustomed to the girl's exploratory motions, when Rachel thrust her thumb into the comparatively fresh orb, snickering as the boy's fading cry was suddenly renewed with all the vigor she expected following the initial outburst.

Rachel moved her thumb methodically from from one testicle to another, carefully jamming and compressing each one while analyzing their bizarre behavior, cautiously devoting the same amount of attention to each while examining Paul's comical feedback.

Eventually satisfied with the results of her trial, the young girl looked up at Laura.
