Stretch

Alex, laying on the floor with her limbs spread out, her eyes closed, took long deep breaths. Eventually, when she was sure her orgasm had finished, she stood up and allowed the cum to spill off of her and onto the floor. She pushed her feet through it, feeling the stickiness between her thighs, and walked into a side room that contained a shower. She turned it on, hot, and stepped in to wash off the cum and sweat from her skin, hair and face. Stepping out she grabbed a towel and dried off before returning to the tentacled creature in the main room.

A skinny tentacle slithered towards her and got close to her crotch. It tickled her clitoris and lips and rubbed it for about a minute, maybe two, her pussy getting wet. Then it opened its orifice, latching onto and sucking her. Alex moans lightly, allowing the creature to suck her off, her pussy already sopping wet, ready for everything else this monster had to give. The tentacle sucked and smacked her clitoris in its mouth quickly. Her arms got goosebumps and a moan escaped her lips. She took a knee, then two to the floor and propped herself up with her elbows.

Suddenly she felt the presence of another small tentacle behind her and it slowly entered her ass. It went in and out, in and out, before it thickened slightly larger. It kept entering and exiting over and over, and grew a little bit more as it fucked her. Alex moaning audibly as she took the creature's ever expanding arm. "Fuck..." she squealed, feeling every inch of the cock. She tried to grip the floor as she approached climax, her nails digging into its flat surface. "So big..." And just as she was about to cum, both tentacles stopped playing with her, leaving her just on the edge of ecstasy.

But Alex would not need fret. She was lifted by four tentacles, one for each of her limbs, her arms and legs spread very widely apart. She saw the monster below her and was moved directly above its massive penis. She wondered how it would ever fit inside her, but she remembered the drugs they gave her: the Onyxatine. Could it really stretch her so far that the monster would be able to fit inside her? How far could it go?

The tentacles lowered her onto the tip, a few little ones spread her pussy gently over it. "Oh... fuck..." she moaned. The tentacles holding her pulled her down onto the cock until it was firmly inside her. Alex felt the stretch of her pelvis allowing the monster to penetrate. "God damn! So big, oh my god..." The tentacles then let their grip on her loosen, allowing gravity to take control and pull her further down the cock. It stretched her stomach, poking out of her lower torso more and more as she slid down its shaft. She ran her hands through her hair, then rubbing her tits and body as she took the monster inside her. Her legs bent and stretched, arms unsure of where to go; there was nothing to grab onto.

The tentacles grabbed her again and lifted her back up the length of the beast. "Oh my god... oh my god..." She took a few deep breaths before being released and - "Oh... yes..." - the gigantic cock penetrated her again, pushing into her and stretching her stomach outward to fit itself inside. This happened many, many more times. Another tentacle emerged and approached her mouth. She opened her mouth and accepted it. The tentacle stretched her lips out wide to fit in and pushed itself down Alex's throat, filling her esophagus with its length. Alex's eyes rolled back as she took both dicks in her holes, allowing herself to be pleasured and stuffed.

Time became abstract and unknown. Alex was fucked for a long, long time, coming and coming onto the enormous cock in her quivering pussy. Eventually the creature came as well, filling her with the sweet nectar she would now crave. Her stomach grew slightly as she sat on the cock, and her throat would fill up as well. She felt it hit the back of her throat. They set her down on the floor gently before leaving her body. The white cream slowly leaked out of Alex's pussy, creating a puddle around her. She gurgled the cum as she lay face up and coughed it out, the white stuff covering her face and getting in her nose and hair.

With a sudden animalistic energy, Alex licked up the cum from her body and the floor, desperately wanting to consume every last drop, muttering, "I want more! I want more! I need more cum! More cock! Please, please, please..." She lay on her side and scooped the semen towards her mouth.

A familiar, human hand gently lay on her arm. "Don't worry, slut," he said. "You'll get plenty." The monster howled as a second needle was put into her arm.
