Your roommate enters through the door, setting her bag on the table next to it. She turns around, sees you and cries out.
"Hey, I'm ba- what the heck is that!"
She yelps in surprise at your new look, you walk over to her and calm her down, telling her it's alright. She seems to calm down and looks you over, we smirk as she studies your body, wait- we? She steps closer to you and traces a finger up the rubber suit.
"Wow, this is really cool, where did you get it?"
We explain to her about how it bonded to me two days ago, and all the stuff I did with it. Your roommate pinches the suit and pulls at it, letting it go with a wet slap.
"Wow, it feels like really gooey rubber! Hey, I have a secret I want to tell you. . . I've kinda been into this kinda stuff, like I find it really fucking hot"
Hearing this, a wave of lust comes over you, and you grab your roommate, picking her up and carrying her to your room, tossing her on the bed. We rip off her clothes, showing off her modest curves and chest and leaving her naked. Your erection growing in the shiny suit, the black cock sleeve forms and your dick stands straight up as you straddle her, rubbing your rubbery dick on her chest, you then stick your cock in her pussy and she cries out in pleasure
"Ah! You're so big! Please keep fucking me!"
The slimy rubber of the suit acts as a natural lubricant, allowing us to slide in and out of her pussy. We sink deeper into our lustful desires, and shiny tendrils start to crawl up my face, going down my throat and coating my head and a wide, tooth filled mouth with a long meaty tongue forms, jagged white eye patches are where my eyes should be. My roommate gasps in shock as the tongue makes it's way around her neck, constricting it.
"St-stop it! Please!"
We can't hear her as we continue to pound her pussy, cumming hard with a loud roar, the tongue tightening around her neck
"PLEASE! YOU'RE HURTING ME! I CAN'T BREATHE!"
This snaps me out of it, the tongue retracts and the suit uncovers my face, I get off my roommate. She quickly get's up and looks at me fearfully.
"What the hell is wrong with you! You nearly killed me! I don't want to be with you anymore until you get your shit together!"
She runs out of the room, I look at my hands, the glossy black rubber perfectly coating my hands. This suit is changing me, I almost killed my best friend, I have to get it off, now! I open my window and shoot a web line outside, launching myself out into the night sky.
