That they want to have crazy virus fueled sex, consequences be damned, of course!

Dani stared at table in front of her. She was only vaguely aware that the conversation continued around her as the other three argued about whether what Sarah had done was right. Dani wouldn't have cared much about that kind of arguing anyway, but right now her mind was in turmoil. Sarah had reignited feelings that she'd worked so hard to suppress for years. Yet again she found herself struggling with what she wanted and what society told her was right. But she kept wondering, did **** even matter for the Infected?

Her mind kept trying to think about sitting in the rain crying, on that day, and she kept forcing herself not to think about it. She had never been willing to talk to anyone about that day, even herself. She had felt so… empty. A lifeless doll. A part of her knew that everything Sarah had said was true; it was unnatural, it was wrong; but it also felt so right. Now Sarah was apologizing, saying that she'd felt the same way the whole time.

"Do you love me?" Dani whispered.

Sarah and Tera stopped talking immediately, their more sensitive hearing having no trouble with the soft words. Ashley plowed along, until she realized that the others had stopped and were staring at Dani.

"Of course I do," Sarah answered.

Dani allowed a smile to touch just the right side of her face. "Like a sister?"

"And like a woman."

Dani could have sworn that her sister was gazing into her soul. She stood up, with Sarah following suit. She took a step and wrapped her arms around her sister's waist, her eyes slid closed and her lips puckered in anticipation. For what seemed like an eternity she hung there, anxiously waiting for her sister's response.

Sarah's hands slipped around her shoulders, and her soft, velvety lips brushed across Dani's, sending Dani's heart racing. Every inhibition melted away as her blood started pumping, her hands dug into Sarah's butt, and her lips went back hungrily for more. A jolt of lighting shot straight into her crotch as Sarah's hands found their way into her hair. Dani kissed her sister with the thirst of a dying woman.

Sarah's hands slid down to her butt and copped a nice feel before sliding down to her legs and picking her up. Dani grabbed her sister around the neck, kissing Sarah deeply before Sarah deposited her on a bed. She barely noticed her own scramble to get her clothes off before Sarah's mouth greedily sampled her ample breasts.

"Ahhh," Dani moaned. Sarah started to pull away, but Dani pulled her back down. "That's good," she purred.

Sarah wiggled free, "You think that's good?"

Sarah's tongue slipped into her labia and was taking turns teasing her clit and diving into her. "Oh my fucking—mmmmmmhhhhhhmmmmmm—Fuck!" Dani grabbed the sheets as her whole body contorted from pleasure.

"Do you like my tongue?" Sarah asked slyly.

"Fuck Sarah, that's the most amazing thing I've ever felt."

"I can make it longer and more nimble than a normal tongue. I've been dying to try it out," she laughed lewdly before diving back in. Dani could barely control herself, it felt so good; she'd never felt the kind of pleasure that her own sister was subjecting her to.

"Sarah, fuck, Sarah. I want more," she panted.

"I was hoping you'd be ready soon," Sarah smiled deviously.

Dani's eyes were wide as a thick dick slid out of Sarah right where her clit should have been. "Holy shit, is that real?"

Sarah laid on top of Dani, letting the tip of her cock push lightly against Dani's entrance, "Does it feel real to you?"

"Give it to me," Dani tried to sound sexy, but it sounded **** in her own ears. Dani felt her lips spread and the burning heat of Sarah's cock slowly enter her. "Uhhh, Sarah I'm—"

"I know," Sarah gentled nibbled her ear, "you're already infected. The pain will only last for a second."

Dani felt a sharp burning, and then as quickly as it came it was gone. Her body wanted more, she gasped when Sarah's monster bottomed out and their hips were pressed tightly together. She didn't just feel it, she could see the way it deformed her stomach, which was oddly arousing.

"I know," Sarah gasped, "that's so much cock inside you. I bet you never thought you'd lose your virginity to your sister's cock, huh?"

"Shut up and fuck me," Dani growled, shifting her hips irritably.

Sarah started to move her hips, pushing her cock in and out at a steady rhythm. Dani groaned, savoring the friction and fullness of her sister's cock. Her sister's bigger breasts were so full and heavy against hers. Even as Sarah's breasts had grown from her meager A cup to more than two handfuls each, Dani's D had grown to the point that Sarah wasn't sure how many hands it would take to hold them.

"Fuck, that's hot," Sarah moaned. "I always loved your tits. And these… Mmmm."

Sarah felt herself growing closer to orgasm, her muscles aching for release, but Dani wasn't there yet. She willed herself to hold back, the pleasure in her groin growing from a smoldering ember to a blazing fire; pleasure so intense it was pain. Dani panted and groaned under her, her lips forming a perfect "O" as the moans cascaded out of her mouth.

"Oh fuck Sarah, fuck! I'm going to cum… I'm… cumming!"

Sarah felt the torrent of cum explode out of her balls and down her cock, shooting out in hot waves into her sister's virgin cunt. Euphoria radiated from her cock to fill her entire body, and she collapsed on the bed, blissfully fulfilled, her soft cock slithering back up into her body.

Sarah stared down at her sister. "I love you."

"Don't tell me you're done," Dani whispered.

Sarah opened her eyes to see her own cock's twin slither out of Dani's slit.

"Oh yeah," she moaned at the sight of it, wiggling to spread her legs and reveal her dripping sex. "Fill me up," she giggled.

Dani didn't waste any time plowing her cock into her sister's wet hole. She felt every glorious inch of it part her sister. It was like a dream come true, having sex with her own sister, the thought nearly made her cum. She leaned over Sarah, letting her massive breasts fall across Sarah's again—how she loved that feeling!—and began to move her hips.

Every thrust was new and amazing, the way Sarah's walls clung to her, urging her to go again but deeper and harder drove her wild. Sarah's gasping moans didn't help her self-control, and soon she was plowing Sarah with everything she had. Her balls slapped heavily against Sarah, and her cock slid in and out with a lewd 'shlick'.

"Fuck yeah," Sarah said, "Fuck your sister with that cock!"

"Oh," Dani grunted, she felt the strangest tightness building in her groin.

"Full me up with cum, Dani. Full me until I burst!"

The tightness suddenly burst, and Dani experienced the first male orgasm of her life. Cum flooded out of her like a hose, and she watched with awe as Sarah's belly swelled with it, quickly growing into a huge round orb and pushing Dani backwards.

"Fuck," Sarah moaned.

"I love you too," Dani smiled happily.

Sarah closed her eyes and her stomach quickly pulled back in as her body absorbed the massive load of cum.

Tera was dancing back and forth, she was so horny she could barely stand it. But Sarah had forbidden her from having sex; she couldn't even masturbate, because that was having sex with herself.

"Sarah, can I have sex now?"

"Oh shit Tera, sorry, of course you can."

Tera smiled, "Oh yeah. I'm going to fuck you so good S—"

Ashley cut her off. "Actually," she dropped her clothes and sauntered seductively to where Sarah and Dani were laying on the bed, "Sarah is already occupied." She reached out her hand for Sarah, who hesitated momentarily before taking Ashley's hand.

"Come with me," Ashley whispered in her ear.

Tera stared at Dani hungrily, who was still laying on the bed with a fat erection. "I wouldn't mind riding that."

Ashley pushed Sarah down and straddled her, letting Sarah's cock slip between her ass cheeks. "I wanted it to be you," she said softly. "It has to be you, because I fucked up all those years ago. I had someone special, and I couldn't stop thinking of myself long enough to consider how she felt, how you felt. I'm sorry, I—"

Sarah pushed her fingers against Ashley's lips, "We all make mistakes. I made some too. I'm glad you want me now, I haven't been able to stop thinking about you since you got back. I know a dick isn't really you're thing—"

Ashley pushed her lips onto Sarah's cutting her off with an uncharacteristically sloppy kiss. "There," she giggled. "I'm infected now, right? You can order me to love cock?"

"Ashley, I don't—"

"Then maybe I can just do it myself," she smiled, lifted her hips, and took all of Sarah's massive cock into herself in one swift motion. "Putain! Oh fuck, that's amazing," she panted. "I love you Sarah."

"I love you too."

Ashley started rocking her hips, feeling a rush as Sarah reached up and put her hands on Ashley's hips. She'd never even liked penis-like toys before, but the virus burning through her veins was changing that. The excessively full feeling in her loins was amazing, the way that Sarah's cock rubbed her… unimaginable. Every fiber of her being burned for more and her hips shifted from rocking to bouncing. She leaned forward, and felt Sarah's hands shift to her butt. With only half a thought, her butt expanded, giving Sarah something to dig into. Her hands pressed into Sarah's breasts; their massive softness wouldn't have thrilled her before, but now they drove her wild, her own breasts swelling to match them, and when she pushed her breasts into Sarah's, she nearly came. She just wanted more and more of that thick cock, and she felt the familiar anticipation of an orgasm. Inside her, Sarah's cock bucked, spasmed, and then expanded as hot cum exploded into her. Ashley's mind and body fell off the precipice at the edge of bliss, her own orgasm exploding through her body in hot, lapping waves of euphoria.

"I love you," Sarah whispered.

She collapsed on top of Sarah dazed and utterly spent, unaware of anything but the pleasant remains of her orgasm and the joy of hearing those words from Sarah.
