No. You can't let her stay up here, she's infected! It doesn't matter how far along she is, pretty soon she's gonna be a fully fledged bimbo! You've already chickened out of helping that man find his daughter, it's your duty to protect these people up here.
You turn to Stephanie and try to look as sympathetic as possible. Surely she's not going to go quietly. Perhaps someone else up here can help you get her gone?
"Stephanie," you begin tentatively, "Look... I promise we will look after your little boy. I will. Nothing's going to harm him but you have got to leave! I'm sorry!"
"No! No, I can't leave I... mmmMMmmm ohhh... I'm... alright..." she says through a moan of pleasure. Her hand goes to her boob and she massages it, and you think you see it grow slightly in her hand. "Just let me stay... I need to... look after Thomas."
"You're not listening to me," you say, hardening your face, "You're going. You've got to."
"No! I'm not. You're not... a mother... you don't know... ohhhh, fuck..." For just a second her eyes glaze over and she looks at you with a slack-jawed expression, "Oh, god... I really wanna fuck you..." and then she's back, "No! No! I'm okay... I'm... fine!"
"Stephanie. Get off the roof. Thomas will be okay, you have my word," you say, beginning to get not just angry but scared too. She's losing the fight!
"NO!" she shouts. You notice people definitely looking your way now. A man comes over and asks what the problem is. Begrudgingly, with an apologetic look in Stephanie's direction, you tell him that she's infected. She devolves into a desperate state of pleading; promising that she's fine, that she won't attack anyone, that she needs to stay and look after her son. But the truth is revealed plain as day when she moans again in arousal and you watch as her breasts grow at least a cup-size.
"We've got to get rid of her!" you say to the other man, who nods in agreement. Together you bend down to scoop her up. Little Thomas is crying even louder now, seeing his mommy getting dragged away.
Everyone on the rooftop is calling for her to be removed as she screams for help. You and the man drag her towards the ladder, but just as you're about the force her down, she turns and glares directly at you.
"Fuck you!" she screams and spits in your face. Her saliva was aimed well and hits you right in the eyes. Disgusted, you wipe it away, blinking rapidly. When you can see again she's smiling. "Gotcha! Enjoy being a bimbo too, you bastard!"
The man with you tells her to shut up and forces her back down the ladder. But you're beginning to panic. The spit got in your eyes! No... no, no, no! She's infected... and that means...
Arousal suddenly flares to life in your groin and you feel yourself becoming hard instantly. Holy shit, you're infected! No!
Stumbling away from the edge of the roof you try to comprehend what's happening to you. Your cock is so hard it hurts! You feel like you're going to just cum in your pants!
"Hey, dude! Are you alright?!" a young guy asks.
"N-no..." you gasp, "I think I'm... arrgghhhh!" you cry out as all of a sudden your shoulders collapse inwards with a loud 'crunch', rounding off and taking on the look of a woman's. Holy shit! You're turning into a bimbo!
"Everybody... run! I'm... uggghhh... I'm changing!" you call, and people get the message. Especially when your normally short brown hair lengthens rapidly and becomes a shining blonde. You can't believe that this is it! After everything you've been through today -- you're finally turning into a bimbo! This is... great! Wait, what? No, it's not! 'Crack, crack!' You drop to one knee as your hips burst outwards, widening. Oh, god! You need to cum so bad! You reach down, undoing your trousers and tearing them off -- anything to get to your cock! But it's shrinking rapidly and your balls are pretty much gone already.
"I'm becoming a girl...!" you whisper to yourself and smile, the virus beginning to work on your mind now. You can see people running away from you, trying to get off the roof before you're done changing. No... why don't they stay and have some fun?! You gasp as you feel your hands shrinking, and watch in shocked awe as you see each nail lengthen until all ten are long and manicured. Ohmigod, they look so cute! No! What are you thinking! You're a guy! You've gotta find Sarah -- your wife! You can't turn into a girl... she's a girl... you can't be one too! You can't be hotter than your wife! Because you're gonna be... you just know it! You're gonna be such a hot babe! You're gonna have gorgeous hair and gorgeous skin and awesome titties! Wait...
You look down, tearing open your shirt with your long nails. Whilst your nipples are big and swollen and womanly, you've not got boobies yet! Come on, boobies... GROW! And like that, they do. And quickly. Your chest expands, two globes of sensitive flesh erupting from your chest and growing bigger and bigger and bigger. You moan in delight and grab your swelling tits, cumming hard as your old, useless male genitals are consumed by a soaking wet pussy that opens between your legs. Ohmigod, ohmigod! This feels so good! You need... you need...
You need cock.
And lots of it. The last part of you that is Brad fizzles away as your face changes into that of a beautiful lady. You're Bambi now. With a moan of delight, your transformation into a bimbo completes. Your intelligence dropping, your sexual arousal skyrocketing. As if to welcome you into your new reality, you cum again but as a woman this time, screaming as you squirt all over the rooftop.
Ohmigod, this is, like, so awesome! You need a man... oh god, you need a man. Your arousal returns almost immediately, your pussy dripping juice. The last of the people are just getting down the ladder. You smile, knowing that there's gotta be a hunky guy among them that can fuck you silly. With a giggle, you take off after them, completely naked.
Watch out, boys! Bambi's coming!
