How to Transform Your Partner

He could feel himself approaching climax. No amount of sensitivity limiting gel could keep him from being brought to orgasm by this ultra sophisticated sexbot. He watched his erection slip in and out of her tight slit through the gap in her crotchless panties and he panted out, "Sierra, lose the underwear. I want to see all of you. Oh and also...increase the size of your nipples."

Nick put his mouth on a nipple, feeling it swell under his tongue, and watched her panties shimmer away in a digital haze.

He was close. He felt himself growing larger, harder. He thrust himself deeper and more forcefully into Sierra again and again, her ultra-tight folds providing the perfect amount of resistance against his intrusion. Her pussy lips glided over his length elegantly, contouring to the shape of his member as he pushed in and pulled out over and over again.

Nick grabbed Sierra by the buttocks and spun her around 180 degrees so they returned to their earlier cowgirl position. She straddled him as he sat on the couch. Her systems quickly adjusted to the new position, the servomotors in her legs again taking on increased loads to seductively lower her snatch down the full length of Nick's aching hard-on.

Sierra detected Nick's oncoming orgasm and loaded up her own climax subroutine to sync up with him. The vaginal walls of her synthetic pussy began pulsing all around him.

Nick was on the cusp of emptying himself inside Sierra. He pulled her head down engaging her in a soft kiss. Her breasts jiggled against his chest. He moved his mouth around to her ear and whispered in, "Increase the size of your breasts one more time."

She leaned back, giving Nick a full view of her expanding mammary. Simultaneously, she detected Nick's engorged member pumping it's load into her tight pussy. Her systems reciprocated, moans escaping her lips and lubricant coursing from the perimeter of her snatch as she climaxed along with him.

She leaned in to re-engage in a kiss but was interrupted when a loud 'POP' sounded off from within her plastic chest. Her face twitched between a handful of unrecognizable emotions and her body froze. She fell forward, the full weight of her immobilized body pushing into Nick who anxiously spoke up, finishing up with final few powerful thrusts into her plastic vagina "Sierra what happened? Sierra are you okay!?"

There was no response.

In shock, Nick just held Sierra's body quietly. All he could hear was the roar of drives and whir of fans spinning up inside of her. The seconds stretched on as she continued to lay there, motionless, and unresponsive.

Eventually, a digitally garbled and tinny rendition of her voice emerged from behind her unmoving lips. "ERROR. ERROR. ERROR. BREACH OF ELECTRICAL CONTAINMENT IN ADAPTIVE MACRO-COMPOSITE ARTIFICIAL DERMIS CAPACITOR SUB-GROUP UPPER_CHEST_22B."

Her voice briefly paused before continuing, "ATTEMPTING TO RECTIFY ERROR. ATTEMPTING TO RECTIFY ERROR. ATTEMPTING TO RECTIFY ERROR. ATTEMPTING TO RECTIFY ERROR. ATTEMPT FAILED."

Several more moments passed by quietly before her static twinged voice returned, "ERROR. ERROR. ERROR. CRITICAL DAMAGE SUSTAINED TO ELECTRICAL SUBSYSTEMS 12C, 12B, 13A, 9L, 22B, 11A, 11D, 11F AND 14F."

Nick muttered to himself, his face buried in his hands, "Why does this always happen to me?"

Several servomotors crankily roared back to life and Sierra, quite loudly, turned her head to face Nick. Her eyes blinked several times and her normal voice returned, albeit chopped up and stuttering, "It's okay Nick. Yyyyyooouuu-yoyoyo-you-you you got-got-got-got-t-t-ot-got the full warranty on me!"

Nick laughed earnestly, his face lighting up. Even in the throes of her crippling malfunction she could surprise him.

He looked back down at her, eager to engage her back in conversation, but her eyes were vacant, the sounds of her internal electronics subsiding.

He held her in his arms for several moments, savoring her touch, savoring the time he'd spent with her.

"Don't you worry a thing Sierra. You and I...we're gonna be taking a trip to FORMARE first thing in the morning."

He leaned forward, kissing her on the forehead and closing her glassy eyes for what would NOT be the last time.

"With you Sierra...maybe I'm not so lonely anymore."
