Yes

As Grace reached out for Mallory, thoughts raced through Mallory’s mind.

“Would it really be that bad to turn into one of them? Grace seemed to be trapped in an eternal state of euphoria and sexual pleasures. It wasn’t like she would be eating people after this. No she would just be having sex for the rest of her life. Sex didn’t sound so bad. And besides Mallory was really horny at the moment. Something about watching her best friend fuck herself in front of her and then collapse in a puddle of her own cum made Mallory really wet. She had never thought about Grace in a sexual way before, but now all she could think about was Grace’s dripping cunt before her.”

Mallory decided to give in.

As Grace reached for her, Mallory didn’t step away. She allowed Grace to grab her and push her to the ground underneath Grace.

Grace let out a giggle.

“Good girl, now… now.. I’m going to make you feel better than you ever have before,” Grace slurred at Mallory.

With that Grace firmly planted her lips on Mallory’s. The kiss started off gentle, but very quickly became Grace forcibly kissing her. Grace’s tongue explored the insides of Mallory’s mouth, as Grace sucked on Mallory’s lips.

The kiss was enough to push Mallory over the edge. Mallory responded to Grace’s kiss and kissed her back almost as forcefully. Mallory could feel the fire that had been inside Grace ignite in her, making her incredibly horny.

As Grace kissed Mallory, Mallory pushed her skirt against Grace’s dripping pussy, and felt some of Grace’s orgasm seep into her panties. This furthered Mallory’s hormones and made her want to cum even more. This clouded Mallory’s mind and she began to feel a sense of blind pleasure wash over her.

Grace reached her hands around and began to massage Mallory’s breasts, giving her a whole new sense of pleasure. Grace forcibly squeezed Mallory’s breasts, then twisted her tits, causing Mallory to let out a massive moan.

Grace continued kissing Mallory for a long time until she eventually got bored of it. Grace wanted cum. She broke the kiss, leaving Mallory a dazed mess with Grace’s lipstick smudged all over her face.

Grace began to draw away from Mallory’s face and towards her crotch. Giggling feverishly, Grace began to pull away Mallory’s skirt and panties, exposing her pussy. Grace giggled again before dragging a finger along the outside of it. This was enough for Mallory, who between the kiss and stroking, came.

Grace moaned as her breasts were splashed with Mallory’s cum. Then she began playing with her breast and licking Mallory’s cum off them. As she did this Mallory watched as Grace’s breasts grew more reaching double G sized. She now looked like she had two watermelons on her chest. Mallory couldn’t wait until her breasts looked like that.

“Your cum’s so sweet Mal,” Grace moaned out, “I want more!” she slurred in blind ecstasy.

With that Grace bended towards Mallory’s pussy. Grace stuck her tongue out and began to eat out Mallory. Mallory screamed out in pleasure as she felt Grace’s tongue begin to explore her pussy. Mallory’s pleasure grew exponentially and so did the fire inside her. There was no hope for Mallory going back, she was at this point fully infected.

Mallory didn’t last long with Grace eating her out. Grace’s virus controlled brain knew exactly how to make Mallory cum. A few minutes after the first, Mallory climaxed again, then again a few more minutes later. Mallory splattered Grace’s face with her cum, which Grace lapped up.

Each time she came, Mallory could feel her mind drifting away and being replaced with the blind desire to fuck. Grace had spread the virus to Mallory through both the kiss and oral sex, ensuring Mallory became infected. Mallory could form thoughts, but they were mostly focused on extracting as much pleasure as possible from Grace.

Mallory locked her legs around Grace’s head to keep it in place at her pussy. Mallory’s shirt was long past very tight on her, and her breasts were pressing hard against it. After cunning one more time it became too much for her shirt, as her breasts expanded and popped out of both her shirt and bra.

Grace continued fucking Mallory for a little while longer, until she came on last time. By this point Mallory’s mind was mostly gone. She was trapped in a lust filled stupor, with nothing but the desire to fuck and be fucked.

Standing to her feet, Mallory admired her new form in the mirror. She had pale grey skin and breasts that were each the size of a cantaloupe. Her pussy was dripping with her cum, which ran down her legs and pooled beneath her. Grace’s breasts had grown a little bit more and she was now completely covered in both her own and Mallory’s cum. This made Mallory extremely horny and she wanted to continue fucking Grace, however Grace was uninterested right now. Grace wanted to fuck someone who wasn’t a zombie already. Mallory found that she did too. She could tell that sex with a human would always be more erotic than sex with a zombie. Thankfully, the two girls had someone nearby who would be able to help them with that.
