As their tongues danced for dominance, Sym strecthed over Gwen's face and encased her in the mask once more while leaving her mouth still exposed to Peter's lip. "P-Peter mmmmh... I need you to fuck me now!" Gwen wrapped her arm around Peter as she tackled him onto the sofa. "Gwen! C-condom!" Gwen's Symbiote reacted and sprouted out a tendril to Peter's cabinet. As Gwen grabbed his massive buldge, Sym brought back the brand new condom. Peter instinctively reached out and grabbed Gwen's breast, massaging, squeezing it. "Ooooh! You haven't lost your touch I see." Peter pushed Gwen's head away as their lip separated. He then buried his face into the crevice between her two big breasts. "Peter! Off!" Gwen grabbed hard on Peter's jeans and ripped them with ease. She pulled off his shirt quickly and threw it on the ground. Sym then completely covered her face, including the mouth. Gwen was once again in her Symbiotic form. She tore apart Peter's tight boxer as his humongous dick stood straight up. Gwen's Symbiote mask cracked open, forming a human like mouth. She wrapped it around the tip of Peter's cock. His semen instantly started flow as the feeling of a rubber, Symbiote alien is vacuuming his dick. "Ooooh Gwen! Yes! Suck me! Suck it! Eat it whole!" He grunted as Gwen's mouth widen, and encased his dick. Cum flew into her mouth as she swallowed all of it. Slowly, some black substance spewed out of her mouth onto his massive cock. "Is that for me?" Peter moaned as the new Symbiote spreaded around his penis. Taking on a life of its own, it squeezed his manhood hard. It traveled around his privates and coated his leg. His muscle became more define, his abs started to glimmer in the latex like substance. His hard nipples were carressed by the new Symbiote as it consumed his arms. Soon enough, it devoured his head, leaving him in a shiny black Symbiote suit. Peter moaned as he could still feel Gwen sucking on his 8 inch cock, that was now somehow fifteen inch. White Raindrop eyes and spider symbol appeared on his featureless costume as he suddenly had the urge to fuck Gwen and fuck her hard. "Mmmh your dick is delicious! The Symbiote told me being symbiotic was good, but being She-Venom is even better. Can I Peteeey?" Gwen pouted, wanting to experience it all. She want the power, the lust. "Then I'll be Venom!" Peter replied in a lower, more manly voice as his muscle started to bulk up. His arm strengthen, his Chest grew bigger as his leg also increased in size. Peter's dick started to swell up as it grew even bigger. While for Gwen, her breast grew seven times bigger. Her ass got firmer and more rounded. "Peter fuck me now! I want it! Don't worry, I won't get pregnant if your dick is covered." Gwen ensured their problem was gone as she was knocked off the sofa onto the marble floor by two big slimy tentacle. "I'll fuck you alright. How would you like your fucking? Well done, medium, rare... Or raw?" Gwen trembled in excitement and forgot to answer. "I'll take that as a raw" Peter slammed her down on her knees, doggy style. He sent out two tendrils that started to connect him to Gwen's breast. She then suddenly felt a warm sensation as her breast starts to wobble. It was being played with as Peter tease her clits as he moved his dick near her flaps. "Damn it Peter! Do it already!" He slammed his newly enhanced cock right into her pussy. "AAAAAAAAAH! OH GOD PETER! AAAAAH!" Gwen screeched in pleasure as she felt Peter pouncing her with his new dick. Peter grunted as he pushed and pulled, his dick getting deeper and deeper into her pussy every second. "Not enough..." Gwen tried to look at the Symbiote Peter Parker but instead moaned in the overwhelming pleasure as she was fucked in ALL her holes. "P-Peter I'm going to c-CUM!" Green glowing juices exploded from her vagina and onto Peter's dick. It then was slowly absorbed by the Symbiote. Peter retracted his dick and tendrils from her ass and vagina, then flipped the girl over on her back. He then once again inserted his penis into her genital. "Oh Gwen I'm going to-" Gwen's body was suddenly taken over by Sym as Peter was about to pull out. Her Symbiote suddenly sprouted tendrils and anchored his dick inside of her pussy. Peter felt his penis connected inside of Gwen's vagina as his Symbiote pulled away from his dick. "Gwen I can't pull out! I can't hold it!" Sym pulled closer but got her control taken back by Gwen as she pushed Peter away. His symbiotic cock flung into the air as his cum splattered onto Gwen's body, staining her with white semen. /What was that for?! He almost cum! We need it!/ Sym was angry at the situation. /No! This is my body! We can't just make me pregnant out of no where! We're not even married!/ Gwen argued as she moan from the shockwave left behind. Peter was panting exhaustedly next to her. "Haaaa.... Haa... T-that was one heck of a close call." Peter spoked softly as he wraps his arm around Gwen. /But you need to reproduce!!/ Sym was very annoyed but didn't know what Gwen was saying. /No I don't! Human work different from Symbiote's. And YOU are using MY body. MY body./ Gwen was still shaken up from the fact Peter almost made her pregnant. /I DONT CA-Oh... I-I'm sorry. I got really caught up in there did I.../ Finally she realized her mistake. /It's fine but don't do it again./ Gwen snapped back to reality after her conversation with Sym. She found that she was on Peter's bed somehow. Last thing she remembered was she past out on the cold hard marble floor. /Hhhngh.... Sym can you form some clothes for God sake!/ She was about to walked out the bedroom but looked down to see herself naked. Her Symbiote responded as it quickly wrapped around her. Instead of being in their usual white costume, Sym formed her classic Venom costume. "Hmm... Might as well. I had been wearing whites way too much." She opened the door as the Symbiote retracted down to her neck and formed a V shape on her breast to show some skin.
