Exploration

Celine stopped gnawing on her finger. Merely her subconsciousness had noticed that it had felt softer and squishier, but also more sensual and arousing than usual. Her tongue palpated the flabby, gelatinous thing between her teeth. Her first notion involved a slimy garden hose. Then disgusting images of snakes and snails and worms unsettled her. Celine spit it out, gazed down on her finger… and for the very first time laid eyes on one of her green, serpentine tentacles. She instantly recognized it from her dream. The tanned skin-color of her finger transitioned smoothly into a scaly-looking but slick green tendril, as if it would turn into a snake halfway through.

“Holy fuck!“ Chloe cried out. “What is that? Are you alright?“

Celine’s field of vision pulsated. Within a single moment, a wave of various emotions flooded her brain. Of course terror and surprise overshadowed any other. She didn’t even perceive Chloe’s question. That creature which sprouted from her finger would probably jump into her face any moment. Living with Chloe, she had seen dozens of body-horror movies, alien invasion flicks and tentacle pornos to know how those scenes ended. Those characters were always doomed.

However, beneath her intense shock and worry, Celine came upon a sensation which seemed to compensate her concerns. An awareness of whatever just extended from her finger. It eased her mind a bit to actually feel its movements, whatever it was. It meant that there was a chance to control it. Maybe even steer it. Gasping for air, Celine managed to procrastinate her panic attack and instead focused on her snaky finger. She imagined it bending away from her. Without delay, the tendril flexed to the side. The abruptness of the swift movement caused both Celine and Chloe to screech. The latter jumped on her bed. “What the FUCK is that?“

But Celine just starred at the tentacle with rising fascination. Did it really bend to her will? Reassessing herself, she mentally ordered it to to rise and lower, to curl and then to wave. The tendril obeyed without a millisecond delay. As if it was part of her body. Moreover, it turned out to be far more flexible and pliant than a normal finger could ever be. The bud at its end, which reminded her of that of an artichoke, split open into four jaws, and at command, it made a silent, squeaking sound. “Hey little buddy,“ Celine whispered. “You’re harmless, aren’t you?“

Chloe had grabbed a pillow which she held like a shield in front of her. “Harmless? How can you tell?“

“I think it‘s alright,“ Celine said, mesmerized by the tendril‘s smooth movements. “It... is part of me. It feels... kinda amazing. Really.“

Chloe slightly lowered the pillow. “Celine, whatever this thing is, we‘ve got to amputate it! That‘s beyond anything natural.“

“Just hold on a second,“ Celine said and focused on her finger. Instantly the eel-like extremity shortened, changed color and completely retracted to transform back into an ordinary human finger, along with the red nail polish she had applied the previous evening. “Awesome,“ Celine chuckled and flexed her finger. It still felt remarkably boneless. She even managed to bend it 180 degrees.

Chloe cringed. “Ok, what the fuck is going on?“

“I don‘t know,“ Celine said, still regarding her hand. “But it feels… well, kinda arousing.“ She willed her finger into a tentacle again. This time, it made a slimy squelch as it extended outwards. This was accompanied by a sudden pleasurable sensation, which Celine could only describe as sexual in her mind. As if her finger just enjoyed a tiny orgasm. Expanding the tendril reminded her of shoving a thick dildo into her groin, an activity she was all too familiar with.

Sensing no stretching or pressuring ache, Celine wondered how long the tendril could flow out of her finger and if the pleasures would reinforce. Thus she didn‘t will it to stop when it extended forwards one meter. Then two meters. Three meters. The tentacle slapped against a wall and began to coil itself like a snake upwards it. At impact, a jolt of ecstatic sexual thrill caused Celine to gasp out loud.

“What is?” Chloe stepped closer to inspect the glistening and somehow slick surface of the alien extremity. “Does it hurt?”

“It must be some kind of erogenous zone,” Celine tried to explain. “It feels like the best fucking handjob ever, but everywhere along it.”

Mesmerized, Chloe watched as the tentacle kept expanding along the wall. Now she first noticed its smell and was weirdly attracted by it. It was an odor which didn’t come close to anything in this world. It stung into her nose and drilled itself up into her brain. Chloe felt dizzy for a moment, but then shook her head and asked: “And you can control that penis thingy?”

“I don’t consider it a distinct creature. It’s part of me. Like moving my arm. And I can sense every inch of it. Wait… hold on.” An inner intuition motivated her to try something. As if her new biology urged her to explore itself. Celine focused on one particular spot along the tentacle, about one meter away from her hand. Precisely there, a second tentacle branched off like the root of a tree. The offspring wasn’t thinner nor less controllable than the tentacle which kept crawling along the wall, which in all had reached about ten meters by now. Again it ended with an artichoke-like bud and the squelching sounds doubled in volume.

Chloe stepped back a bit. “This is so fucking eerie. Are you doing this?”

Celine nodded. “I think the tentacles can branch off everywhere.” The second stem hadn’t extended half a meter when it replicated itself again. This time, three tendrils forked off from the same inch and extended in different directions. Counting five green wiggling appendages already, Celine felt confident that she long hasn’t reached any limit. Her sexual stimulation grew with each new inch, prompting her to keep going. She wondered what would happen if she willed dozens more tendrils to sprout, just out of curiosity.

Chloe screeched as more than half of the room suddenly got filled with Celine’s slippery, squirming and frantic tentacles. The sounds they made as they slithered around each other reminded of a huge body of viscous slime being dropped from great heights. They knocked over furnitures and decorations, covered their bed entirely and pilled up on the floor. Chloe already eyed the door when the entire mass of alga-like eels stopped moving at once. Not one tendril among hundreds dared to twitch or make the smallest sound.

“Ups,” Celine giggled, struggling to contain her intense arousal. “That’s… a lot. But I’m still in control. Don’t worry.”

“How the fuck is that even physically possible?” Chloe shouted. “Where’re they all coming from? This doesn’t make any sense at all!”

The tentacle-girl shrugged. “Dunno. But fuck me if this doesn’t feel amazing. Like… imagine having a hundred G-spots stimulated at once.“

“Is that why you’re so chilled about this?“ The dizzying oroma of the tentacles was overwhelming now. Chloe assumed that they must spread some sedative, alien pheromone since she had calmed considerably and now wondered how such a serpentine creature would feel inside her pussy. Her tentacle-fetish awoke fully now and mesmerized she starred at the squirming mass of green roots.

“Trust me,“ Celine sighed. “It’s fine. Here, you can touch it.“ One tentacle started wiggling towards Chloe’s hand. Reluctantly she nudged it with a finger before sliding her finger along the surface. While it felt sturdier than it looked, the tendril was still squidgy and boneless. Other than expected, it didn’t secrete any mucus. A moist film of slime produced the the shiny gloss and made her finger just a bit greasy instead of sticky. Now intrigued, Chloe clasped her hand around the tentacle and stroked.

Celine gasped aloud. “Nnnghh… fuuuuuck.“

Instantly her girlfriend let go. “Did I hurt you?“

“I think I just came,“ Celine panted. “Hard. Jesus fucking Christ, this feels better than an orgasm. I hope they can retract just as easy, though.“

Just by thinking it, the plethora of Celine’s new toys withdrew back into another. As if she had pressed a reverse button on a remote, the den of tentacles diminished tendril by tendril until only few were left. The last one disappeared as it transformed back into Celine’s finger, leaving no sign of their existence but an alien scent and some smears on the walls.
