Need some lube

First things first: lube. She looked all around for something slippery to slather the hole-wrecking horsecock with, but couldn't find anything of the sort. This caused her girthy little three inch half-chub to droop in sadness, expelling a clear globule of precum as it did so.

Samus lit up. "Of course! I have all the lube I need right here, just sitting there, packed away in my fat prostate!" She said with girlish glee, "all I have to do is make my little clitty cum, and make sure to shoot it all over Mr. Analihilator here, and bingo presto, I've got myself a slimy, slutbreaking, sex toy!"

Grinning to herself, she reached down to her little soft clitdick with one hand, gently grasping it between her thumb and forefinger, before slowly stroking up and down her pathetic 3 inches of limpness. She let out girly moans and pants, stroking her worthless little femboy girlcock faster, and faster, slowly building up speed until she was furiously tugging and yanking on her now 4 inch erection.

She was sweaty and red-faced, her tongue lolling out of her open mouth to slap against her chin, her little perky A-cups jiggling slightly, with her fat puffy nipples growing diamond hard, and her areolas(which covered almost half the surface of her boytits) swelling outward till she was nearly a B-cup!

The real show, however, was happening down south. All that jilling-off had set her two curvaceous, meaty, thicc thighs, her shoulder-wide, door-jamming hips, and of course her enormous, phat, wobbly, gigantic, jaw-dropping, pawg-ass buttcheeks to clapping, jiggling, and slapping against each other like crazy! They filled the empty hallway with a cacophony of fleshy smacks and lewd twerking noises, flinging droplets of buttsweat everywhere with each ground-shaking undulation.

Those mighty spheres of flesh that she called her asscheeks would slam around her twitching donut hole, briefly concealing it from view, before swinging wide open again as if to invite any monstercock inside the meaty ring of muscle that lay nestled in-between.

Samus was still violently jerking the shit out of her girldick, and her motions had gained an edge of desperation as no matter how hard she squeezed, tugged on her little clitty, and no matter how close she got to the edge, she just couldn't achieve climax.

She was panting with exhaustion at this point, perspiring rivers of sweat, and her knees were quaking(which had a very nice effect on her clapping hills of buttmeat), almost buckling beneath her.

"Hah, hoo, hnnnggooOOH FUCK!" She yelled out in a rage, stamping her foot(causing another storm of jiggles), and finally collapsing from exhaustion, her huge bussy making lewd sucking noises as it suctioned itself to the metal floor. "Why can't I fucking CUM? I got so close but than it seemed to get farther away."

"Miss Aran, if I may draw your attention to something," the AI suddenly said, startling her for a second, "it would seem that the Femboy upgrade has made it nearly impossible for you to reach climax by any normal means, rendering conventional methods of masturbation obsolete."

"Wait, you're saying I can never cum again?" Samus asked tearfully, looking down at her shrinking weiner, and aching, overfull blue-balls, "but if I don't cum soon, my balls are going to explode!"

"I didn't say you could no longer cum anymore, but that you need to use a alternative form of pleasuring yourself," replied the AI, "by the way, in your **** frenzy earlier, you succeeded in fulfilling your goal without even realizing it."

Samus wondered what the AI could mean, when she looked down at the momentarily forgotten sphincter-splitter, and seeing it almost completely coated in a thin sheen of her own sweat, which still dripped from her own body, her anus especially moist, and most importantly, lubed.

"I think I've figured out that 'alternative method of masturbation,'" Samus said, her eyes burning with lust, as she bit her plump, cocksucking lips.
