Use Serum

Seems like things have been dangerous lately… a lot of tough fights. You have two serum vials. You know that it’s a risk, but it’s time to use one. There are six possible side effects… you will receive one at random, but the serum will also make you stronger. You have to get yourself and Hana out of this mansion alive. You have ****.

You open a vial and drink the serum, feeling warm all over your body. And lightheaded… wow.

You look down worriedly at your cum-covered body, but you don’t see any changes. You just feel especially warm… and tingly… and empty between your legs. It aches. Hesitantly, you reach down, lifting your cock out of the way to touch your pussy. The lightest touch makes your knees buckle and you moan.

Your juices run down your legs.

Your pussy is now extra wet, extra sensitive, and extra needy… you crave cock.

You also feel more vigorous, and your vigor is restored.

Time to get moving. You head back into the Art Room, and this time you expect the F-Psycho to be there. You walk in with your gun ready and take the shot as she grins and hisses at you.

Your bullet hits. The woman howls and shoots cum into the air as her back arches.

You fire again, and you get her a second time. She falls backward over a padded bench, landing awkwardly with her legs in the air and the rest of her on the ground. Her cock erupts a second time, covering her face in semen. She’s down.

OK. You’re glad to be finished with her.

The Main Hall is just up ahead. You push through the doorway, jogging onto the tiled floor. The statue is there.

You look up to see Hana heading down the stairs. She’s naked and in the same condition as you, her little cock bouncing around like crazy. She has her VC Pistol in her hand.

“No luck,” she reports.

“I got it,” you say, waving the dildo at her in triumph.

“Fuck yeah!” she cheers, throwing a fist into the air.

The scientist on the ground groans. You know now that she is the one all the files referred to as “M”.

You both turn as the thin, red-haired woman in the white coat stands up. You know that look in her eyes, but a moment later her skirt bursts into tatters as her newly-grown cock springs free.

“Oh shit,” you and Hana say in unison.

That is a serious cock. It’s as long as yours, but like… four times as thick, and bulging with veins. The head is… suspiciously red, and pouring precum, which splatters on the floor, making it slippery.

Unfortunately, this is exactly what your serum-enhanced pussy craves.

“Hello, nurse,” you say.

“Riley!” Hana says in a strangled voice.

Right. You have to focus.

This enemy is literally the only one between you and escape. There’s no reason to conserve resources. You pull the OoCO Launcher out of your fanny pack, load it up, and shoot it straight at her.

The bullet explodes in a pink mist.

M howls and arches her back, then seizes her huge cock with both hands and jerks it feverishly. A river of pungent cum splatters to the floor. You load up your second round and fire again.

She collapses in a puddle of her own semen, rolling onto her back and jerking out another load that soaks what remains of her outfit.

She growls and… to your horror, starts to stand back up, looking at you hungrily.

“Good try,” Hana says as you throw the empty launcher aside.

Hana raises her pistol and fires, striking M in the leg. M jerks and grunts, but doesn’t cum! She’s too powerful to get off from a single shot from a pistol!

You fire as well, but miss. Thanks to your upgraded pistol, you get a second shot as she moves toward you. But you miss!

Hana knocks you out of the way as M makes her grab.

“Eep!” Hana cries as M lifts her off her feet. M is… very tall. You try to stand up as M simply lifts Hana’s slim, petite, wiggling body, and takes her little cock into her mouth. She sucks, and Hana whimpers and cums easily, her shaft contracting and expanding between M’s lips.

M drops Hana on the floor and spits the jizz on her, making a triumphant pose.

Whatever! You grab your pistol and fire at her. But you miss! Un-fucking-lucky!

M kneels spreading Hana’s legs and slapping her enormous cock down on her belly.

“Oh wow,” Hana says, wide-eyed.

You try to intervene, but M knocks you aside, then shoves into Hana, who screams and thrashes in ecstasy, her small cock spraying all over her chest.

You get ready to take another shot, but slip in all the jizz and miss again!

M just keeps fucking Hana ruthlessly. You could grab the gun and fire again, but Hana is almost out of vigor. You can’t let her go out like this.

You grab your last serum vial and lunge, slipping through the fluids and forcing it into her mouth. Hana chokes it down and shouts, thrashing free!

M falls, and Hana slides away, her vigor restored. She stands back up and you look at her worriedly. Her cock swells to hardness, and as you stare at her, fat, bulging veins appear all over it. She looks… actually, she looks incredible. You want that cock. No! You have to focus!

“Uh oh,” Hana says, looking down at her newly-veiny cock. “I feel sensitive.”

“Don’t feel, just shoot,” you say. M is coming for you again.

You fire, and finally, you get a hit on her. She lets out a grunt of rage and falls to her knees, unleashing a torrent of semen onto the tiles. Yes!

She spreads her arms and shrieks. What remains of her outfit explodes from her body as four flesh-colored tentacles erupt from her back, waving in the air. Each is as thick as your cock and… they are cocks!

“Oh boy,” you say, your vagina absolutely aching for them.

Hana dives, sliding through the cum to her pistol. She grabs it and fires. The bullet hits, and the tentacles all ejaculate, but M’s huge, main cock does not. She lumbers forward.

You aim and fire. You hit her! She stumbles, more cum pouring out.

This time it’s you that she’s after, and you can’t get off another shot before her tentacles reach you. You try to dodge, but she slams you to the ground, the tentacles holding you down as her body pushes against you from behind. You’re so wet down there that even a cock that size just glides right in.

“Oh god, baby, yes,” you moan. “Mm.” You eagerly push your hips back, and M gives you exactly what you want, pushing in hard. As your eyes roll back and you orgasm hard, Hana puts her gun to M’s head and shoots her.

M cries out and falls down.

“Ooohhh…” you aren’t ready to fight yet. That was so good. So good. You want more.

Hana grabs your gun but slips in the jizz, splashing down on her back with both guns. She fires but misses.

“Shit!” She rolls out of the way as the tentacles shoot out, grabbing you instead of her. They wrap around your legs, pulling you across the slippery floor. One slides up between your legs and inside you.

“Yes!” you cry out as the tentacles go deep. M reels you in, her big cock waiting and dripping in anticipation. You’re dripping too. You want it so bad. You have cum so many times… your cock now just dribbles on your belly, aching. If you lose much more vigor you’ll have to use your flask, which will put you at an even worse disadvantage! This is bad!

“Riley!” Hana shouts.

You open your eyes and look through the haze of pleasure to see your gun flying toward you. You catch it and aim at M, firing.

You hit her!

The tentacles let go of you. Hana takes another shot, but misses!

You try to get up and out of the way, but you can’t go anywhere on this slick floor! M crashes down on top of you, pinning you flat and shoving her huge cock into your waiting pussy. You drop your gun and wrap your arms around her thin body, hissing as she drives into you. The pleasure is absolute. Your cock and pussy both erupt like volcanos.

Hana fires at point-blank range and does not miss.

M jerks, and stops fucking you. She looks down in confusion at her huge cock, which is throbbing out of her control, buried in your pussy. Her cum bubbles out of you as your insides overflow.

M’s eyes roll back, and she falls with a slapping noise into the puddles of cum. Her tentacles lie around her, limp. Jizz drips from her magnificent penis.

“Oh…” you watch your stomach shrink as that huge load gushes out of you.

“Are you OK?” Hana asks, kneeling beside you.

“Never better,” you reply. You feel pretty good. She leans down and gives you a sticky, salty kiss. She takes your hand and helps you stand up.

M is finished.

Together, you stagger to the statue. With sticky hands, you slam the dildo key into the waiting orifice. An audio file of a girl’s moan plays, and the statue rotates back into the wall.

A moment later, the bars and shutters covering the windows and doors all lift.

The door is open.

You are woozy from exertion and… everything. You pull Hana in for another kiss. Your cum-covered body rubs against hers, and you feel her incredibly veiny cock against your incredibly wet, dripping pussy.

“They’re out there,” she says, meaning more F-Zombies.

You hold up your VC Pistol. “We can handle them,” you say.

Holding hands, you leave the mansion.
