Mitch McDermott and Amy Vanpelt, Engineers with a Love for the Switch [Bondage, Denial, Sci-fi, Slightly More Intense]

Mitch and Amy stared at their new invention. A black collar that was relatively thin and covered in LED lights, with a purple square for the spinal tap. The specs, planning, and everything else had all been done in-house, literally. In their house, to be precise. And it had all been stored on hard drives that they owned, never exposed to a network of any kind. The product would never, EVER make its way to market if they could help it.

Maybe with extensive redesigns they could turn it into something usable, but they would have to make sure that no one could replicate anything like the original. It was just too dangerous in the wrong hands. Or in the right hands, honestly.

Testing had gone well, on animals and the like. It was hard since their anatomy was different, but the chimp that Amy and Mitch managed to smuggle in got their hopes up. After testing, they had sent him to a wealthy pet owner that they knew well, for one of his private exhibits. Its life would easily be more cushy and pampered than it had ever been as a test subject, and all it had to endure to get that golden ticket was some **** behavior.

Amy absentmindedly rubbed her husband's strong arm. Her short, thin fingers dug into his muscled shoulder without her even realizing it.

Mitch wrapped his arm around Amy's waist and pulled her close. She leaned her head in, resting against his side. He petted her hair gently, and she sighed into him, the tension fading slowly from her body.

She softly said, "D-do you think it will work?"

He chuckled, then said, "You're too humble for your own good sometimes."

He felt her hand slide across his abs, then wrap around his waist. The side of one of moderately sized boobs pressed slightly into his side. She said, "Thanks honey, though you could stand to be a little less confident sometimes."

She grinned up at him, and stuck her tongue out. Mitch loved how she kept acting like that, even well into their thirties. He pulled her tight to him, then said, "Maybe so. I guess we complement each other well. Want to go on a date sometime?"

Amy huffed and said, "I don't know, I think it might be dangerous to go out with an egomaniac like you. You might do things to me, or even bring out the worst in me."

Mitch jumped as she suddenly darted her hand down and squeezed his ass. His hand on her head squeezed briefly, and she shuddered. He said, "Would that really be the worst thing in the world?" He raised his arm that was clutching her waist and slowly dragged his fingertips from her stomach to her collarbone, skirting just around the outside edges of her boobs.

Amy's body shivered against him and pressed tighter. "I dunno, maybe?"

"I think you know it wouldn't." He tapped her throat and added, "In fact, I think I'll put something right. here. Something that will bring out the worst in you and in me. What do you say."

Her voice husky, Amy responded, "I say fuck yes, if you let me do the same to you after."

"I was hoping you'd say that!" Mitch ruffled Amy's hair, and she sighed softly. "Should we try it out?"

"N-now?"

Mitch tightened lowered his arm, and again held Amy to him. He gently massaged her scalp and said, "We have to try it sometime. I can go first."

"You don't have to-"

"I insist, Amy." Mitch spun her around, then pulled her into him. Her soft butt pressed into his quads. One arm wrapped around her torso securing her to him, while his other forearm reached up and diagonally across her body. It partially pressed into her chest, and his hand reached just high enough to continue stroking the side of AMy's hair.

She sighed, and he felt her body relax into him. Her head nestled into his arm, and her arms pulled Mitch's arm even tighter to her torso. Finally, she said, "Thank you, babe. I mean it."

"I know. Thank you for being a good sport about this." He gave her a slight squeeze.

She said, "Well, as much as the dangers do unnerve me, after our tests and analysis I really think we should be good to go. It's not like you're the only one who wants this, I'm just, um..."

Mitch spun her again, then pulled her into a hug. Her soft body pressed into his muscular frame tightly as he said, "Babe, it's no problem, really. Honestly, I'm kinda in the mood for it anyway."

"Oh, is that so?" Amy's hands began to press into Mitch's backside, and she pushed him backwards. "Is my strong man's offer to test the waters for his wife's sake or the product of his desire to be my fucking bitch?"

One of Amy's hands gripped his side forcefully, while the other tightly gripped his hair. He briefly closed his closed his eyes, then said, "A-a little of both."

"Uh huh, sure." Amy let him go, then she pushed one finger into the center of his chest, knocking him back a bit. Her strength that belied her size still managed to surprise him, at times.

He felt the crotch of his jeans slightly tighten, and controlled his breathing. Amy grabbed the collar, then strode over to him. She quickly wrapped it around his throat, then said, "So, three hours to start with, using the rules we discussed?"

"Y-yeah." Mitch felt his body flush with nervous anticipation. He breathed hard, hoping that nothing would go wrong, though no part of him really thought that it would, or even could. It was just the nerves of the moment.

"Alright then." Amy finished lining the collar up, and snapped it shut. Immediately, Mitch felt the needle prick into his spine, then expand. The collar flashed, and Amy stepped back, tapping her foot nervously.

Mitch sat onto the nearby couch, his whole body feeling drained. Amy was instantly at his side, her hand stroking his chest. She said, "How do you feel? Are you doing okay?"

"Yeah, just... tired."

"Okay, that was expected." She sat on the couch next to him, then said, "Here, just rest against me until it passes, okay? And let me know if you feel anything wrong."

"Okay." He snuggled up to her and rested his head in her lap. Her thighs supported him, and the hand stroking his head and back made him calm down a little more. They sat there for several minutes in silence, the collar whirring softly.

Finally, the collar gave a ding and flashed green. "Well, it's done," Amy said, still rubbing her husband's back. "Let me know when you're okay to start."

"Will do," he murmured, the fatigue already seeming to melt from his bones. "And I'm fine, by the way."

"Figured."

He nuzzled into her, mentally preparing himself. After a few seconds, he said, "Okay, I think I'm already fine. The fatigue doesn't seem to last that long, which I thought might be the case."

"Well, we still have to be careful. It seemed like the calibration process affected each user differently."

"True enough." Mitch sighed, then sat up and experimentally flexed his arms. He stood up, waving his legs in front of him, then did a simple stretch. "I am good though, I don't feel anything anymore."

"If you say so. Should I start the timer?"

"In a second. Have you changed your mind about what you're going to do? I'm just curious."

Amy smiled evily, then tapped Mitch with her foot. She said, "I'm sure you are, bitch. Did you really think that the fantasy I told you was what I would start with? This is going to be one. Long. Surprise."

Mitch flinched, then said, "Oh. Fuck."

"Oh fuck indeed." Amy stood and approached Mitch, then traced her hands along his body. She said, "I think someone likes that idea though."

"Oh, and who is that? It sure as hell isn't me."

"This one tells a different story." Her hands moved down and cupped his crotch. He hissed through his teeth as her hands gripped his half-erect dick through his jeans. "I think you do like the idea."

"Y-you know that-"

Amy shut him up by pushing him back into the sofa. He sat down, then stared up at his grinning wife. She said, "I'll let you pick one of these first basic functions, as a test: On Edge, Pain, Vibrator, Human Doll, or Masturbate. After that, it will be all me and things might get a little more wild. Think you can handle that?"

"Yes, Amy."

"What the fuck was that?"

She glared at him and he gulped, then said, "Yes, Mistress."

"That's what I thought. Don't you worry, we'll be taking care of this bad boy soon enough." Her foot reached out and rested on Mitch's erect dick. He bit his lip while she said, "So, what'll it be?"
