She’ll tell you what she is going to do

Sammy whispers something to your roommate as your heart hammers, she’s looking at you with her eyelashes drawn low over her smoky eyes. The way she is looking at you is making you squirm, the tension grows, Sammy keeps whispering. You feel like a sinner before St. Peter at the gates waiting for some kind of verdict to be handed down. Your roommate eventually waves a giggling Sammy away and fully turns her attention on you. You can’t stop yourself from trembling before her. Her voice sounds so sweet when she finally speaks “Sammy has some ideas, but I think it’s important that we punish you for being a LIAR.” Her words flatten you like a truck as they roll over you.
“I!” it’s all she lets you call out before silencing you.

“No, you don’t get to speak because all that comes out of that mouth of yours are lies. Sammy fetch a gag!” You watch the naked Sammy skip off into the red light bedroom and stare at your roommate in disbelief. This might be your last chance to say anything. You think about what you need to say and then blurt it out as fast as you can “Willyoucorruptmepleaseohpleaseoh-”
she places a restraining finger on your lips and you fall silent immediately.
“Silence now my pretty little liar, you have lost the right to speak. You will speak only when told to, do I make myself clear?”
Your body trembles again and you nod willingly relinquishing your free speech. Sammy prances back into view with a shiny black ball attached to a black leather strap. You swallow just looking at it.

The ball fills more of your mouth than you thought it would, you lick the slick visitor and feel yourself starting to drool. “Good, now that I won’t be interrupted where was I?” she thinks for some seconds.
“Oh yes, I specifically requested a 100% straight roommate.”
She moves behind you and Sammy slides up in front of you. Sammy grins up at you before pulling you down for a light kiss on the edge of your lips.
“Being a Futa is the best you have no idea! My ass and c♥ck feel so much better now, my titties and throat…”
Her words stop as her lips press against the side of your neck and begin to sweetly suck. Hands are slipping your pants off, they pool around your ankles leaving you mostly exposed. Your thighs push together, but you can hide nothing from these two.

Your roommate’s body presses against your back you hear an ass being smacked and Sammy sucks harder as her round ass undoubtedly recoils. You roommate’s angelic voice whispers in your ear but you can hear a dangerous edge of anger in her honey sweet tones.

“I meet plenty of men who will fuck anyone that gives them a chance, some men who think they’re straight but when push comes to shove… well they’re more than happy to make love to a Futa. I’ve even some men who lust after Futas.
The Futa chasers are the biggest pervs by the way.
For a man like that it’s not that he doesn’t mind a fat cock on a feminine body.
To a man like that, it’s a PLUS!
He doesn’t just want a tight pussy to creampie, he’s hot and heavy for the moment. The moment when a big titted tiny waisted leggy Futa switches things up on them and makes him moan like a bitch for her hot load.”

Sammy’s cock is pushing against your erection though your boxers and you can feel your roommate’s pulsating iron rod pushed up against your ass.
“That type of man didn’t last long after real Futas showed up. Those guys are out there living their wildest fantasies everyday. As Futas!
But, I’ve always hoped there was a fourth kind of guy out there, the straight guy. A man who honestly has no desire for Futas. You got my hopes up! See, I’ve never met a straight man. Sooner or later you all end up on your knees sucking my dick.”
Sammy giggles “Yep!”
Your roommate grinds her aggressively erect cock against your yielding ass terrifying and exciting you to no end.

“I like getting my dick sucked by the way, I Love getting my dick sucked!
I’ll tell you a secret, I used to be one of those Futa chaser men. That’s why I was one of the very first people to transform. I absolutely loved it! Just look at me, I know you understand, Sammy told me♥.
You could say I got in on the ground floor. I’ve lost track of how many men and women I’ve corrupted. There’s a bit of a problem though, with the way things are going there won’t be any men left. You can call me a preservationist.”
Her laugh is a light waterfall washing over the turmoil in your brain.

“I’ve been searching for a straight guy because I want to save men! The only problem is that kind of man doesn’t seem to exist. I’ve brought in a lot of ‘men’ with listings like the one that got you.”
Your body shakes like a leaf at this revelation. She sighs and sweetly kisses the back of your neck. “Poor boy did you think you were my first ‘straight’ roommate?” Sammy’s hot tongue slides against your neck and your shirt is pulled up, you lift you arms and it disappears. Sammy kisses your pec and starts to suck on your exposed nipples.

“I’m sure you saw the other Futa’s listings, explicit. All but begging and promising to fuck. Those attract the wrong kind of man, the kind of man who wants to get corrupted. But now I see they might have been right all along, we might as well just go for it since there don’t seem to be any straight men.”
She sighs and even this sound is enticing making your boxers strain against your hard dick!
“Are you wondering why I’m telling you all of this?”

You try to say something but the gag reduces it into an indistinct grunt. Oh right, you nod.

“You’re the ‘man’ who has lasted the longest, by far. Usually it takes less than a week for a straight man to knock on my door and try not to beg as he asks to be fucked. I used to make them beg too, I’d force them to completely debase themselves, hoping that it’d draw out some spark, some flame of resistance in them. Instead all I learned was that men are completely spineless. Once I break that thin veneer of theirs they’ll do anything to be with me.
I had such high hopes for you.

How about I tell you another secret? Ana at the stripclub she isn’t the one who can break ‘straight’ men with a lap dance, that’s me. She is the second best. Still, I am impressed you didn’t give it up to her.
I need to thank you sweet roomie. You’ve helped me decide something important. You’re the last straw. Now that I know you’ve given up on your manhood just like all the rest I’ve lost faith in men. There’s no point in wasting my time looking for straight men who don’t exist.

So, yes I will corrupt you. I’m going to give you what you want so badly and it will be even better than you’re imagining. I’m going to take you and fully brush away your fragile, defective, broken manhood and make you exactly the kind of irresistible Futa you’re craving.

I know that you’ve already been thinking about it. What you’re going to do when you’re a Futa. Sammy told me about your fucking dirty ideas, you were planning to corrupt Sam. Cutie you’re not even a Futa yet and you’re already thinking about who you want to fuck, but as you can see it’s far too late for Sam.”

You look at Sammy.

“It’s your turn now, but first I have to punish you for being a bad bad man.”
