She gets interrupted before thinking about more fun

Sue just thought about another round, having only cum twice in the time of Joanna’s absolute ecstasy, but a sound distracted her: the sound of glass crushing and a voice calling her name. “Sue? Are you there?”

It was Jess, and Sue turned around to the door. The glass was crushed open and someone tried to find the doorknob with their hand. Sue moved towards the still locked door and called out with a raised voice. “Back off, I'll open the door.”

Sue always was athletic and had a natural power in her legs and arms, thanks to a short time in the cheerleading team of the college, but she never crushed a door with her pure strength. But to think now she wasn’t capable to do this was just laughable. With a single, strong kick of her bare foot, she smashed against the door and it smashed open. The little bell above the doorframe jangled as the door just crashed out of its hinges and fell forward outside.

Sue wasn’t surprised to see what was going on outside the restaurant. To describe it with one word: chaos. In the whole main floor that led to the different platforms of the central station, naked people were fucking in different pairings, positions, and with loud screams or moans of pleasure. It didn’t seem that anyone escaped the massive panic from a few minutes ago.

In front of Sue stood her sister, Jess, and she smiled a wide smile. Sue could see that cum dripped out her pussy and ass and she returned the smile knowingly. “Having fun, sis?” she asked casually and leaned again the door with crossed arms, emphasizing her cleavage.

“A lot, thanks for asking,” Jess said and winked. “I wanted to see you or Rebecca, but I think Beccy is busy right now. Saw her getting fucked by four men at once and it didn’t sound like she was in the mood for talking right now.”

“So you want to 'talk'?” Sue asked and raised her eyebrows. “Are you done already with fucking?”

“Never,” Jess said and looked half indignant, half amused. “I just want a tail in my pussy and I fear you are the only one having one in this station.”

“Come here you greedy, little girl,” Sue purred and opens her arms. Jess didn’t hesitate and as she reached Sue, she pulled her inside the restaurant, grabbing her from behind and kissed Jess’ neck. The bat wings of her sister laid against her back and so they weren't in the way for a tight hug, full of sisterly love. Sue’s tail automatically moved between her legs and pushed into Jess pussy, making both of them gasp with satisfaction.

“A nice…mmmh…place,” Jess said, moaning slightly, while she touched Sue’s ass with one hand and grabbing her breasts with the other. “Your work, I guess?”

Sue also squeezed her sister’s perky orbs and looked over the state of the restaurant. While she had fucked Joanna, she didn’t take notice of any of the other guests or Nick and only now watched them fucking as well. One man sat on the seats and bathed the girl in front of him in his cum. The blonde girl sucked eagerly on his balls and moaned loud as his load splashed over her. On the table next to them, two women were on top of a second man, one riding his cock, the other one sitting at his face. Both of them were making out and touching each other’s tits, while kissing sloppy and noisy. Joanna only just recovered from Sue’s intensive treatment before opening her legs invitingly on another table. Nick was by her, slapping his cock a few times on her wet pussy, then thrusting forward, making both of them moan loud. He took one of her legs on his shoulder and slowly picked up his speed, making Joanna open her mouth wide while she squeezed her breasts.

“Very sexy,” Jess said, looking over the scenery with the same pleasure as Sue, as if she personally was involved in this herself. “How did you manage to get in? You didn’t use ****, right?”

“I just had a helping hand, a good idea, and a bit of acting experience,” Sue responded satisfied, while her tail thrust in and out her sister’s pussy in the same speed Joanna was being fucked by her former colleague. “Play with their minds and be a bit of your former self and you can have so much fun.”

“I had fun too,” Jess said grinning. “Forcing six men to fuck me was exactly as fun as your little games.”

“Maybe for you,” Sue replied, her tail thrusting into Jess’ pussy even more rapidly. “But I prefer the sneaky way.”

“As long as it satisfies…oh my god…Aaahahah! YES! FUCK ME!” Jess stopped her sentence while she was cumming and Sue followed her immediately. Both sisters enjoyed their climax, still tightly embracing each other, and after it was over, Jess returned to topic as if nothing happened. "…you, I won’t dictate how to infect your victims.”

“Don’t think you can at all, my dear little demon-sister, who turned into a cum addict,” Sue said with a smirk.

“You're no better than me,” Jess said with a fake pout.

“I didn’t say I was,” Sue said and kissed her sister's neck again lovingly. Her tail was moving again in Jess’ wet pussy, stretching her tunnel even more. “We both live now for the next orgasm, over and over again. I'm just saying that I’m maybe a little bit smarter than you when it comes to the approach.”

“Ha-ha,” Jess responded tonelessly, slapping Sue’s ass with her free hand, the other one still massaging her breasts. “If you are so smart, maybe you can help me?”

“With what?” Sue asked surprised.

“The passing trains,” Jess said and jerked her head to the side. “Do you really think they'd stop when they see the orgy at the platforms?”

“Some of them, for sure,” Sue said shrugging. “But yeah, maybe not all of them.”

“So how do we get the people in there infected?” Jess asked and it sounded like she really wanted to know. “There are so many people we're just missing.”

“Do you really think they would escape long?” Sue asked, not entirely convinced of her sister’s worries. “Didn’t you hear Beccy? The big horde is probably on its way and fucking everyone they can find. We will have enough of people to find and fuck everyone who may escape.”

“Yeah,” Jess said, but she didn't sound satisfied. “But I want to do it myself. But I can’t split up into a dozen parts of me…”

“Ask Beccy,” Sue said simply. “She had given the virus to us and I think she knows more about it than we do.”

“Yeah” Jess said thoughtfully, closing her eyes, as the tail in her pussy brought her over the edge once more. “Yeah, maybe you are right. I'll try to talk to her later, when she isn’t occupied with four cocks at once.”

“Good plan,” Sue said and kissed her again, enjoying the feeling of her tail in Jess’ pussy. “I’ll want to take a ride soon to college. Still interested how things are there.”

“Good plan, too,” Jess agreed.

“So, how do we bridge the time?” Sue asked and smiled invitingly at her sister.

“Oh, I think we both know the answer,” Jess laughed and finally released herself from Sue’s tail and hands. She turned around and raised her voice. “Guys? Anyone ready to fuck two incestuous demon-siblings?” Sue laughed as well and turned around too. Some of the men, who had just cum inside their fuck-partners, just turned their gaze to the door of the restaurant, where Sue and Jess stood arm in arm and smiled invitingly at the massive orgy before them.

“Time for some fun, right?” Jess said as three muscled men stood up, cocks standing erected in the air.

“Don’t fall behind,” Sue said and moved in the restaurant, sat herself on one of the tables. “The one with more loads inside her wins.”

“I’m in,” Jess laughed bent over the same dish, wiggling invitingly with her ass as the three men entered the restaurant. “You know, I hate losing against you.”

“I’m up for the challenge,” Sue replied grinning.
