Symbiosis

“Holy fuck!” I yelled out loudly as I took a quick step back, my eyes unable to pull themself away from the massive cock swinging between her legs. Gwen couldn’t stop smirking as her grin only grew wider, and she took a couple steps forward now.

“Isn’t this what you wanted, Petra?” Gwen asked, but there was still something sinister behind her normal adorable voice. “You… you said we weren’t good enough. You… you left us! For that red headed bimbo!” She starts to growl and it sounds like an animal, threatening to break out of its cage, staring at its prey.

“Gwen! I… I’m sorry! I didn’t mean to… I…” I started to sweat now, and my Spider Sense was going crazy. Something was obviously wrong with Gwen, that creature was doing something to her. I needed to stop this! I needed to help!

But before I could even react she had grabbed me and thrown me against the wall, pinning me with a surprising strength I didn’t know she had. “We don’t want sorry, Parker. We want you.” She growls and starts licking her lips and… was her tongue always that long? She grabs my clothes, digging her nails into my shirt, and seamlessly rips it down the middle, shredding my clothes in half and throwing them down to the ground as I let out a sharp yelp while she fully exposes me.

“Gwen… please… This isn’t you!” I say quietly, but before I know it she puts her hands on my shoulders and pushes me down to the floor, on my hands and knees, while her newly grown cock bounces teasingly in front of me.

“You let Harriette use that slutty fucking mouth of yours… You let that sorority bitch use your holes like a cheap whore!” Her voice was gruff, angry, and as she slaps my cheek nice and hard, leaving a red hand print across it, I got another taste of her strength. “Now it is our turn! Fuck us Petra! Suck our thick fucking cock we made just for you!” Before I knew it I felt her hands on the back of my head as she yanks me forward, involuntarily letting my tits wrap around her shaft as my lips move around the head of her cock, and instantly I start to suck her off, not wanting to piss off my friend… or the creature attached to her.

SCHLURP~! SCHLURP~! SCHLURP~!

“Oh fuck~! Fuck yeah~!” Gwen started to moan such lewd moans I had never heard before. This wasn’t her… this was the alien. But… but I didn’t know how to stop this without hurting her. “Suck us~! Suck it~! Fuck~! You dirty fucking whore~! Suck our fucking cock like the slut we know you are~!” Gwen moaned as she began to thrust her hips forward and buck between my lips.

Something about this dick though… it’s like she was telling the truth and this was made exactly for me. Despite its size it seemed to slide between my lips and down my throat with ease. It wasn’t too overly big, but it was thick and long enough to slot between my tits and fuck my mouth so lewdly. And the taste was almost… alluring. I didn’t understand it, but the more I sucked the more I felt like this cock was… perfect~!

Very quickly I looked up and locked eyes with Gwen and, for a second, I saw a glimpse of her old self, soft, sweet, before it was overcome by a monstrous roar as she continued to thrust herself between my lips.

“Holy fuck~! Hah~! Is this what you want, Petra? Huh~? You want someone to treat you like a fucking slut? Like a fucking sex toy~? Huh~? You want a fat fucking cock to use you~?” Her voice was lustful, but broken. You could hear the sadness and pain radiating through it as she thrusted, teasing, breaking, as she stared down at me. “You want someone to claim you~?”

She grabbed me by the hair and yanked me back and off of her cock and I let out a sharp gasp. I knew my friend was in there, I wanted to get her out. I looked up at her with a soft look of desperation, panting hard as I tried to catch my breath, my lips and chin coated in saliva from my own sloppy mess.

“I’m yours Gwen!” I moan, breathing heavily as I hold her gaze. “I’m not MJ’s! I’m not Harriettes! And I’m not the aliens! I’m yours! Do you hear me Gwen?” My voice was ****, breathy, a mix of broken and lustful as I stared up at the blonde. “I love you!”

She glares down at me, her mouth stoic, cold… but her eyes… I could see it in her eyes. For half a second I saw her beautiful, sweet, loving eyes staring down at me. The same ones who nursed me when I was sick, who laughed at my jokes, who made me feel special. I saw Gwen… but then, all at once, she fell deep into the abyss as her eyes went cold again.

“You don’t love us.” She growled as she grabbed me by the hair and yanked me to my feet.
