Fucking to Live [MF] [Incest] [Brother/Sister] [Alien Monster] [Mild Horror]

Rebecca has barely stopped crying, and Brock paces incessantly back and forth.

“Ok, we’ve got to figure out the common thread. Jasmine, Nick, Brandon, Tyler. That thing had every chance to kill you in the car. But it walked away. Why?”

Brandon throws his hands up in frustration, “I don’t fucking know, man. We’re all in our twenties?”

“No, dumb ass. Kylie and Jake were in their twenties, too. And they’re dead. That fucking thing ATE them. And Richard was 19, and he’s gone, too.”

They sit in silence for a moment, terrified that they’ll hear the heavy breathing at the window again or the scratching at the door.

“Maybe…No, it’s stupid.” Jasmine shakes her head, looking down at the floor. Her hands are tight fists wrapped around the hem of her short skirt.

“No, Jasmine. Nothing is stupid right now. If we don’t figure this out, we all could die. Or maybe just my sister and I. We don’t know.” Brock tries to lower his voice, forcing a calm demeanor. “Nothing is stupid.”

“Ok, well. I was just thinking. Like, we all had sex…right? Like recently.”

“What?”

“Yeah, we all had sex right before…the thing showed up.”

Brock puts his hands to his templates and rubs, confused. “Wait, who had sex? You and one of the guys? There’s four of you.”

Tyler high-fives Nick.

“Oh, shut up. Look, don’t fucking judge me. We ALL had sex, ok? It was a group thing.”

“Yeah, it was.” Brandon mumbles. The other boys are nodding along enthusiastically.

“Gross,” Rebecca groans.

“Look, I know that’s it ok. When it came up to us, it like sniffed around our crotches and then walked away. I think it wasn’t interested because we’d had sex.”

Brock looks up at the ceiling. “This is fucking insane.”

“Ok, ok. I guess… Jasmine, I have to have sex with you. And Rebecca, take your pick.”

“Whoa, hold on there cowboy. We’re all safe. How do we know that doing it again won’t mess something up?” Brandon is standing now. “Why don’t y’all have sex really quick and then we’ll all just walk out of here.”

“Fuck me, this is fucked up.” Brandon looks to his sister. At least she’s stopped crying.

Tyler chimes in, “I mean, it’s the safest way, right?” The others all agree, better safe than sorry.

Rebecca and Brock decide to talk it through in the dining room. As the most interior room, it’s theoretically the safest.

“If you think about it, it’s the only option we have.” Brock opens his hand in a gesture of defeat.

“You’re gross. This is gross. I fucking hate all of this.” Rebecca sits in one of the chairs, utterly overwhelmed.

“Well, it’s this or die, right? I’d much rather fuck my sister than get eaten by some alien space monster. If that makes me a bad person, I’m a goddamn terrible human being. Now are we doing this or not?”

“Fine. You know what, fine. I’m going to fuck my brother so I don’t get eaten by fucking Predator out there.”

“Fine.” Brock agrees.

They look at each other for several moments. Brock standing, Rebecca seated. Both silent.

“So should I just take it out or….”

“Oh my God, you’re fucking impossible.”

Rebecca steps towards her brother and makes quick work of his belt and zipper. He’s actually surprised at how deftly she pulls his cock free.

“You’re already like half hard. You fucking perv.”

Brock shrugs his shoulders before Rebecca drops to her knees and takes him into her mouth. It doesn’t take long. Rebecca’s skilled tongue and soft lips have Brock rock hard in moments. He’s just starting to moan and wind his fingers into her hair when she stops.

“Look, fuck me. Make it fast. Cum in me. And let’s get the fuck out of here.”

Brock barely has time to say, “Yes, Ma’am”, before Rebecca’s shorts and panties are around her ankles and she’s bent, elbows on the table. Brock can’t help but admire her for a second. Her plump ass and pale thighs.

Rebecca clears her throat, reminding him of the timetable. “Right. Fuck. Fast. Cum.”

His cock is still slick with her saliva and his head slips in without much trouble. Gripping her thighs, he starts to move his hips. With each thrust, he pushes a little deeper, feeding himself slowly into his sister’s body.

There’s a knock at the door to the dining room. Jasmine’s voice calls out, “Guys, not to rush you. But I think it knows what you’re doing, and it’s not wild about it. It banging at the door again. You might want to hurry up in there.”

Both fighting panic, they try to speed each other along. Brock hammers himself home, burying his cock to the hilt in Rebecca’s tender hole. She gives a gasp as he fills her completely.

“Whoa. Ok, now just cum in me and we’re safe, right.”

“Right.” Brock agrees, moving his hips. He’s moving his full length in and out now. Powerful thrusts bring them together with the sound of slapping flesh. She’s gasping each time, holding onto the table and being lifted off her feet. Slowly the table inches forward, until it hits the far wall. Brock has managed to walk Rebecca and the heavy oak dining table across the room with his thrusts.

But in his fear, he’s nowhere near cumming.

There’s a crash from the living room and screams erupt.

“Guys! It’s inside. It doesn’t care about us at all. It’s looking for y’all. There’s nothing we can do to stop it. It’s now or never.”

There’s a slow scratching at the door. Something sharp and metallic is carving swatches of wood from the other side. After several attempts, the tip of a black, insectile looking claw pokes through. Brock can see it an alien eye looking at him.

All the while, he’s hammering away at his sister. Pounding her with everything he’s worth. His cock is as hard as steel, stretching his sister’s tunnel, literally lifting her from the floor. But nothing. His cock is dry as a whistle.

Rebecca is panicking now, too. Her hole convulses around her brother’s shaft as her body seizes in fear.

“Oh fuck, Brock. Brock, cum in me right now. Cum in me, Brock. We’re out of fucking time. I need you to cum in pussy right now. Please, Brock. I don’t want to die here. Fucking cum right now. Please, do it.”

Something about his sister’s urgent pleas flips a switch in his animal brain. He feels a familiar tightening in the pit of his stomach.

“Oh Thank God!” He screams, slamming home a finally time and releasing everything he has. After several days of camping with no time to masturbate, a more than copious load has built up. He grinds his hips hard against Rebecca’s ass, pouring every single drop he has into his sister’s fertile womb.

“Ha! Fuck you! I’m cumming in her, you bitch!”

They’re both giddy with laughter as the monster turns away. From the other room, the group cheers. “It’s leaving!”

As his orgasm fades, Brock pulls away, releasing a stream of spunk down Rebecca’s thigh. She doesn’t even take time to clean up, simple pulls up her panties and shorts.

“We’re never talking about this, ok?” She raises a threatening finger in his face.

“Absolutely, Absolutely.” Brock nods his head in agreement, zipping up his own pants. “Although, I did hear that anal protects you from werewolves.” But Rebecca is already gone.

  1. Helo I like your post but wish I could add something too. I am banned from some subs for posting erotic work. It was removed and yet porn is visibly allowed on the site as I just witnessed. I have been banned from real girls and sexy stories. Why on earth are they called real girls and sexy stories??? If you can’t post a sexy story ?? Or be a writer published by various websites looking for another outlet.
    It is a corrupt publishing asset designated to denigrate, insult and patronise your abilities. Now I’m intensely irate, a queer erotica writer having my work deleted every day. I hope you have a great big beautiful time with your friend and enjoy the SEX!!:)
