8:00 PM Gwen's Apartment Room

Gwen locked the door behind her and fell on her bed tiredly. "Well, the day is over. I could do anything I want now." She lied on the bed and she spoke to herself. /I'm at Gwen's home already? That was fas-woaah! Hey!/ Gwen lifted the bag with the bikini and brought it to the bathroom. She entered the room so she could take a good look at herself with her full body mirror that was somehow attached to the door. "It's time to try these on I guess." She zipped down her hoodie as it slowly revealed her bra. She threw the top in the corner and unclipped her bra. She set it down next to the hoodie as she slowly  zipped down her jeans. The window was now gaping wide for a perfect vision of her white panties. Grabbing both her jeans and panty, she pulled both of them down. Her cunt, exposed to the cold air starts to dry up. /What's going on out there? I haven't been out of the bag for years! That was an exaggeration hehe.../ The Symbiote thought as it haven't seen the light in so long, it started to get delusional. Gwen reached in the shopping bag and grab hold of the bikini. She held it on either side and put it up near her breast. She then looked in the mirror cutely. "Wow! This fit perfectly!" The Symbiote couldn't take the tease any longer as it jumped on to her breast. "Kya! What the? Did I do that? Hmm, if I have it out already might as well wear it." She reached behind herself and clipped the two ends together. She reached inside the bag once more and grabbed the bottom piece. She quickly pulled it on as it slid between her legs. She pulled it up some more and can feel the material touch her genitals. She then blushed immaturely. "Darn... Boy do I look good!" She posed cutely in front of the mirror. /Uuugh, what happ-Wait! I'm already on Gwen! I-I must act now!/ The white two piece clothing suddenly melted on Gwen's skin. "What the? What is this?" The top piece sprouted tendrils, connecting it with the bottom. It slid down Gwen's waist and completely merged itself together, forming it into a one piece instead. The swimsuit melted more as it poured on her legs and arm. It stretched itself down to her thighs, wrapping around her. Once more, it slid between her leg into her clits. "Get of-oooohhnnngh ooh!" Gwen tried screaming a but it turned into a soft moan of pleasure instead. /D-Did she say she want me on?/ White latex like material spreaded down her feet, coating it. The Symbiote reached up her shoulder and starts spreading itself upward. Her biceps was quickly consumed by the quite mass that was making its way down her arm. Her hand was devoured whole as it turned her fingers into long claws. There was nothing but her face left. Gwen then quickly tried struggling, pulling the slimy material off but it was driving her into a realm of pleasure as it squirmed throughout her body. She became quickly aroused as she felt like a thousand lips was kissing her every curves. Imaginary tongues were licking her pussy as a humping like motion of the costume pushed her. She stumbled forward, grabbing hold on her crotch as she fell in front of her mirror. "Aaah... Must. Focus! Oooh.." Weakly, she grabbed the material on her chest and tried ripping it, only resulting in it hug tighter. It felt like the suit was shrinking. Gwen collapsed on her knees in a doggy style position. Her ass kept moving forward as if there was an invisible figure, humping her, pushing their cock deep within her womb. Gwen didn't care, she wanted this anyway. She decided to join in as she used both of her hand and insert it inside of her holes. The feeling of being penetrated. The feeling of being kissed, by something that was on her every curves. She could take it anymore as she could feel the juices about to spill. She started to spasm on the marble flooring as the Symbiote extends over her eyes. It spreaded over her face and inside her mouth, giving her a passionate warm kiss. Gwen opened her mouth willingly inviting it in. Her tongue dances with the rhythm of the humping motion of the invisible cock. She felt her tongue elongate into a snake like one. Her teeth became sharp fangs, fitting to scare off anyone. She slowly regained vision as black eyes formed on her white mask. Her cum splattered on the floor as the Symbiote scooped it up and brought it to her mouth, force feeding her. "Oooh f-fuck! Mmmh so yummy! AAAaaah! T-that's en-oohmm enough... AAAH AACK MMMMRRGH!" The Symbiote once again entered her mouth, kissing her in the throat and reaching further in but still letting her breath. It pulled out as saliva dripped from her gaping jaw. "haa... haa... P-please s-Ooooh-top..." Gwen could feel the costume settling down but her clits still tingle from the horrifying, yet unresistable amount of pleasure.  Her hand on her crotch let go slowly as it was used to steady herself. She crawled over and grab hold of the sink and raised herself up slowly. "W-what are you?"
