Sees if your last nut still works

You come round to see your captor handling your remaining manhood, she lifts your Shrivelled penis disappointly commenting “hmm, genitalia shows signs of shrinkage after trauma, already at a below average length in comparison to other races I fear for this species if it’s the best they can offer”

She then moves down to examine your remaining testicle, pulling gently on it to stretch its cord to full length, it still hurts to the touch. “Remaining testicle shows signs of increased blood flow, as if compensating for the loss of the other” she notices you shifting uncomfortably under her probing. “Ah subject has awakened again, this is the perfect time to test sexual functionality after the destruction of an organ”

She steps back and removes the binds securing her rack, as the strips of cloth slip free her chest practically bursts out, jiggling intoxicatingly before you. Despite the pain you still feel from your missing nut and the uncomfortable nature of having your remaining one still exposed, your dick rises to attention before such an alluring sight.

“Positive reaction to exposure of breasts, subject seems keen to breed despite perilous position of sexual health.” She notes, before slithering closer to grip your penis, giving it a few long strokes to encourage more blood flow. “Subject appears to be at maximum arousal, penis is still unimpressive but at least shows potential for reproduction should it be needed. Moving to sexual release”

She then grips your dick and begins rigidly rubbing up and down in practiced strokes. After the pain you’ve endured, feeling such pleasure is almost too much and it’s not long before your release a large load, which with In impressive speed she catches in a vial from her side, sealing it before placing it on the table.

“Short response time for ejaculation, reinforcing theory that sexual function is primarily focused on reproductive than pleasure”. You can’t tell what she’s talking to, but do notice a blue stone on her belt glow each time she speaks. “Preparing final test, testicular strength” you feel faint at hearing the words that your last ball could be subjected to more ****. you feel a loop be tied around your testicle and see a series of rings hanging from it.

She then grabs a small wight from beneath the table and hooks it onto one of the ring. “Adding 100g weight to begin, will increase incrementally until testicular failure. Will use more aggressive sexual technique to achieve orgasm” her final phrase confirming your fear that you won’t make it out of this whole, you feel the heavy weight on the doomed testicle.

She leans in taking your cock into her mouth and begins rhythmically bobbing her head on her cock, the feel of her tongue wrapping around it and occasionally probing the tip causing your toes to curl. The sensation would be pure bliss save for the haunting “clink” as she adds another weight to you overextended testicle.

After a few minutes you feel the tell tale tingle of an approaching orgasm, however your nut is positively radiating pain, as it struggles to retract under the weight it’s under, blues veins become more visible as it strains for relief. Marissa pauses for a moment and looks inquisitively at your pulsing ball, stroking it carefully with a nail.

“Mmm, not long now I think” she grins before thrusting your cock back in her mouth with renewed vigour, this time however you feel her adding another weight to your ball with every other bob of her head. You don’t know how much weight she’s added at this point but it must be well over two kilograms and the life giving cord supplying your nut is strained to its limit. Just as you feel inkling of cum surging up your cock you hear...

“Clink-SNAP”

Followed by the sound of weights scattering over the floor and pain flooding your body as you spasm violently in an unreleased orgasm as the woman just watches curiously not even giving you the relief of swallowing the few drips of your final load.

She leans down and picks up the lone testicle, admiring the length of the cord running from it. “Subjects testicles seem capable of stretching to a surprising degree, however can’t withstand large amounts of weights before giving out” She notes before placing the nut in another jar.

“Thank you for helping in the research, I’ll just take your cock and then you can consider the debt repaid” she says nonchalantly, grabbing a scalpel before unceremoniously slicing your dick off at the base. You can only watch in despair as she plops your still turgid member into a final jar, setting it by the remains of your manhood, the now familiar sensation of pain induced **** creeps up on you and you willing pass out.
