ROYAL REWARD: Miss Kobayashi's Big, Hard, Throbbing USB Stick (Inanimate TF, Futanari, Expansion, Corruption, Dragon Maid)

Kobayashi stepped into the apartment with a frown, letting the door slam behind her. Pausing on the welcome mat, she cocked her head and listened, waiting for a sound, but it was strangely quiet. Tohru and Kanna were off in the Other World, but that should still leave… “Ilulu? Ilulu, are you here?” If she’d left without closing the door again…

Leaving her bag by the door, she strolled into the living room, looking left and right for the elusive red-haired dragon. But wherever Ilulu and her flame sacs had gone, it wasn’t anywhere Kobayashi could see them (which was especially impressive when you remembered how big those flame sacs were). Maybe she had gone out again. 

Just as Kobayashi was about to shrug and go take a shower, she noticed something sitting on the coffee table that hadn’t been there when she’d left: a laptop. Bending down, she picked it up with a frown. Had Tohru bought this? That was a little out of character for her. Then again, she was always picking up odd interests. At least gaming would be better than her guitar obsession. 

She flicked the trackpad, curious, and recoiled at what appeared on the screen. Blushing, she planted the laptop back on the table and backed away, her nose bleeding. “Ilulu!” 

From behind her came a quiet giggling. “Hehe, Kobayashi… Why don’t you join in…?” 

Kobayashi barely had time to see the magical circle before Ilulu’s spell struck her. Crashing into her crotch in a flash of bright, flame-like magic, it burned away her pants and her underwear in a wash of fire and left her gasping for breath, her entire body shaking as the energy of it coursed through her. “Nnn~! Ah! Ah!” 

Under the magic’s power, Kobayashi’s twitched and stretched, growing longer and harder and veinier and thicker, its tip curling into a large, mushroom-like cap, even as the rest of the stalk bulked up behind it. Beneath it, a pair of fat balls plopped out of her vagina, and with that the spell came to an abrupt end, leaving Kobayashi standing there and swearing, sweat dripping from her forehead. 

Ilulu giggled. “I’m not finished yet!” Raising her hand, she whispered another magic word, and a second spell struck Kobayashi in the chest, making her scream all over again as her body thrummed with fresh energy. Her ____ snapped upward, erect, and she squealed as flew from its tip, blasting all over the sofa. 

As the last of her clothes burned away, Kobayashi rose into the air amid an aura of magical sparkles, eyes shaking in their sockets as the rest of her body changed. First, her hands vanished into her wrists. Next, her feet vanished into her ankles. Thirdly, all four of her limbs, shrivelled and shrank, disappearing into her shoulders and her thighs respectively. Left with only a single member, she struggled to do anything but shake it and twitch in ecstasy. 

Speaking of, even as Kobayashi gulped for air, her new _____ snapped straight ahead and stretched horizontally, taking on a more cuboid shape. Her urethra expanded with it, revealing not the tunnel of flesh you might expect, but a harsh, metallic one filled with circuitry instead. 

As her _____ froze into a harsh metal connector, the rest of Kobayashi’s body turned to smooth red plastic and congealed, so tight she couldn’t move a muscle. Her face froze in a moan of pleasure–she wanted to scream in delight, but she just couldn’t get the sound out. 

The room expanded, blown to a twenty or more times its size, and with that she dropped to the ground and lay there unmoving, her ____ pointed at the air and just waiting for something to touch it. 

She didn’t have to wait long. A moment later, a gigantic hand appeared overhead, and an equally enormous pair of fingers extended to pick her up. Turning her around, Ilulu giggled in delight. “Let’s see what you look like plugged in.” Still giggling, she aimed Kobayashi _____-first at one of the laptop’s ports. 

As her ____ slammed into the laptop, squeezed impossibly tight, Kobayashi screamed an internal scream that soon grew even louder as the machine snatched her soul and sucked it straight out of her ____. When the sensation came to an end, she found herself standing, panting, and still encocked, in a large, empty white room, like a scene written by an author who doesn’t care much for description. (...?!)

A wall of glass stood before her, and on the other side:

“Ilulu!” she cried, pounding against it. “Ilulu, let me out of here!” 

Looking in, Ilulu giggled even louder. “Let’s try changing some of your sliders…” Her finger twirled over the trackpad. 

With a boing!, Kobayashi’s boobs exploded into a pair of gigantic melons. Her ass soon followed suit, practically dragging her down to the ground with its weight. Squealing in surprise, she tried to conceal herself, but all she succeeded in was futilely _______ her own assets, making herself feel even hornier in the process. 

Ilulu continued to twist and tweak her settings, raising the size of her ____ and her and giving her darkly-tanned skin and exaggerated lipstick. Not to mention a leopard print bra, denim short shorts, and a pair of fishnet stockings. As they squeezed her curves, Kobayashi started to feel strange. 

“Hey, what gives?” said Ilulu, fiddling with the trackpad. “I didn’t add those! What’s going on?” 

Kobayashi’s form wavered and jittered, flashing in and out of existence. Each time it reappeared, she looked a little sluttier, a little less like a wholesome office lady and a little more like a hooker. “H-hot singles in your area,” she crooned, voice staticky. “You won’t be able to resist this game.” She wanted to throw up. 

Ilulu’s eyes went wide. “Nooooo, how did it get a virus…?! Tohru’s going to kill me!”
