The air in Claire’s sunlit living room was warm, smelling of lemon cleaner and the faint, sweet scent of the lavender candle she’d just lit. She stood in the middle of the plush rug, naked from the waist up as the app required, her arms crossed loosely over her generous chest. Her husband, Mark, sat on the leather sofa, phone in hand, a wide, eager grin on his face.

“Package is here,” he announced, his thumb tapping the screen. “Says it’s a first-timer. Got a name pulled from the registry… ‘Bobby’.”

Claire felt a flutter in her stomach, part nerves, part excitement. The broad window behind her showed their quiet, suburban street. Through it, she saw the sleek, silent drone descend onto their front lawn, depositing a small, metallic canister with a soft thump.

“You sure about this, honey?” Mark asked, though his eyes were already glazing over with arousal. He loved this part—loved watching her be taken.

“Positive,” Claire said, her voice a little breathy. She uncrossed her arms, letting them fall to her sides. Her full, heavy breasts swayed with the motion, her nipples already tightening into hard, pink points just from the anticipation. “I need… a break. A vacation from my own head. And the money’s good.”

Mark nodded, getting up to fetch the canister. “And you look incredible,” he added, his gaze raking over her curvy form—the wide hips, the round, jiggling ass barely contained by her lacy black panties, the soft swell of her belly. “Whoever ‘Bobby’ is, he’s gonna have the time of his life.”

A minute later, Mark was back, placing the sealed canister on the coffee table. It hissed, then split open along a seam. A cool, misty vapor spilled out, smelling faintly of ozone and saltwater. Nestled inside on a bed of damp, spongy material was the Rider.

It was about the size of a dinner plate, shaped like a stingray but thicker, more slug-like. Its skin was a smooth, mottled grey, like wet stone. A pair of leathery ‘wings’ lay folded at its sides, and from its center emerged a cluster of short, barbed tentacles surrounding one longer, needle-sharp protrusion. It pulsed gently, alive.

“Hello, Bobby,” Claire whispered.

The slug seemed to stir. It lifted its front end slightly, the tentacles quivering. Then, with a surprising swiftness, it flowed out of the canister and onto the table, moving in a smooth, gliding crawl.

“Okay, Claire,” Mark said, stepping back, his phone now recording. “Assume the position.”

Claire took a deep breath, turned her back to the table, and bent forward, placing her hands on her knees. She presented the smooth, unblemished skin of her upper back, right between her shoulder blades. Her heart hammered against her ribs.

The alien crawled off the table. She felt the first, cool touch of its underside on the small of her back. A shiver ran through her. It began to climb, its body surprisingly heavy, a pleasant, firm pressure gliding up her spine. The leathery wings spread out, flattening against her skin with a slight suction-cup sensation, adhering to her sides just beneath her arms.

Then she felt the central barb press against the base of her skull, right where her neck met her hairline. It was cold, and sharp.

“Ready?” Mark asked, his voice husky.

“Ready,” Claire breathed.

The barb punched in.

It wasn’t pain. It was a brilliant, white-hot spike of sensation that obliterated thought. Claire’s eyes flew wide, her mouth dropping open in a silent scream. Her back arched violently, thrusting her breasts forward. The barb slid deep, and she felt—physically felt—the tendrils unfurling from it, squirming, threading their way up into the cradle of her skull, wrapping around the stem of her brain.

Pleasure detonated through her nervous system. It was an orgasm, but not localized; it was in her fingertips, her toes, the roots of her hair. Her knees buckled, but the slug held her up, its grip firm. Her core clenched, a gush of wetness soaking through her panties. A low, guttural moan tore from her throat as her body was hijacked, cell by cell, synapse by synapse.

Her vision swam, then cleared. But it wasn’t her looking out anymore.

The body—Claire’s body—straightened up. The movements were jerky at first, like a marionette being tested. The hands came up, fingers splaying, then clenching.

“Whoa.” The voice that came from Claire’s mouth was her own, but the inflection was all wrong—higher, brighter, brimming with incredulous glee. “Whoa, whoa, WHOA!”

Bobby—now firmly wrapped around Claire’s brainstem, piloting her body like a kid in a simulator—looked down.

“Oh, shit! These are mine?” The hands, Bobby’s hands now, flew to the heavy, pendulous breasts. They cupped them, weighing them, thumbs brushing over the rock-hard nipples. A fresh jolt of pleasure, Claire’s pleasure, echoed through the shared system, and Bobby gasped. “They’re so… soft! And they jiggle!”

He squeezed, kneading the flesh experimentally. Claire’s body shuddered, a breathy sigh escaping her lips. Bobby laughed, a boyish, delighted sound.

He let one hand slide down, over the soft curve of her belly, his fingers tracing the lace top of her panties. He dipped underneath, finding the soaked, swollen folds beneath. Claire’s back arched again at the external touch, a feedback loop of sensation between host and rider.

“Oh, wow. That’s… that’s the spot, huh?” Bobby whispered, fascinated. He rubbed a slow circle over her clit, and the body he now inhabited trembled, legs going weak. “This is awesome!”

He turned Claire’s head, looking at Mark, who was staring, rapt, his phone forgotten in his lap, a visible bulge in his pants.

“Hey! You! You’re the husband, right?” Bobby said, Claire’s face breaking into a wide, unfamiliar grin. “Thanks for the ride, man! This chassis is prime!”

Mark just nodded, swallowing hard.

Bobby’s attention snapped back to his new form. He bounced on the balls of her feet, making everything jiggle wonderfully. He turned, catching a glimpse of the wide, round ass in the hallway mirror. “Look at that! A full bumper! Does it… does it spank?” He reached back and gave one fleshy cheek a sharp slap. The sound was crisp, the sting-become-pleasure immediate. “Hah! It does!”

He was like a kid in a candy store, with Claire’s lush, mature body as the ultimate treat. Every exploration sent fresh waves of climax-tinged feedback through her helpless system. She was still in there, a muffled, blissful witness to her own body being played with such enthusiastic, clumsy joy.

Bobby spent a few more minutes in rapturous exploration: pinching her nipples until she whimpered, running hands over the generous swell of her hips, even hooking his thumbs into the waistband of the panties and pulling them down to admire the neatly trimmed triangle of hair and the glistening lips beneath.

Finally, he seemed to remember there was a world outside. He left the panties around Claire’s ankles, seemingly delighted by the minor impediment to walking. He put his hands on her hips, striking a pose in the middle of the room, utterly nude now, the grey, stingray-shaped slug clearly visible on his back, its wings adhered firmly just under her armpits.

“Okay!” Bobby announced, Claire’s voice bubbling with excitement. “This is the best day ever! What do we do now? So many buttons to press on this thing!”

Quick Actions:

1. Continue exploring the new body. Bobby’s just getting started. There’s so much more to feel, to taste, to figure out. Maybe he finds the shower, or the bed, or just a comfortable spot on the rug to really get acquainted with every inch of his new host.
2. Go meet the neighbors in your stolen form. The front yard is right there. Bobby’s curious about the outside world, and Claire’s body is a stunning display. Let’s see who’s outside and what they think of the new “tenant.”
3. Go to the local alien bar “Adhesions”. Time to mingle with other Riders! Show off this incredible body, maybe see some other interesting hosts, and learn the social ropes from the pros.
4. Call up a friend of Claire’s. Bobby has access to Claire’s memories and phone. Maybe there’s someone she knows who would be very interested in seeing her like this, or even in joining the fun.
5. Ask Mark for a “guided tour”. The husband is right here, obviously turned on and knowledgeable. Bobby could ask him for suggestions on what this body likes, or even for some… hands-on demonstrations.
