The Lab Mutation featuring Alice Peachy and Emiri Momota. Dr Emiri Momota is busy in the lab, carefully extracting a drop of some mysterious chemical. She isn’t sure what could go wrong, but she’s about to find out. Just as she tilts the bottle, it slips from her hand, plunging straight into a pit of slimy, unknown liquid. A reaction bubbles up immediately, sending her falling backward. Her hand dips into the goo, and within seconds, she collapses onto the cold floor.

When Emiri wakes up, things are different. She blinks, groggy, her body feeling strange. Something is wrong. Her hand drifts down to her crotch, and she freezes—what the fuck is this? There, between her legs, throbbing and massive, is a huge, rock-hard FUTA cock. She’s shocked but horny as hell. Her fingers wrap around it, exploring the length, and she can’t help but stroke it, feeling how sensitive and swollen it is. The more she touches it, the more turned on she becomes.

As she rubs her new cock, the lab door swings open, and in walks Alice Peachy, her coworker. Alice’s eyes land on Emiri’s exposed, enormous dick, and she’s stunned, her mouth hanging open in disbelief. But Emiri is no longer just the cautious scientist. She’s been transformed, and her need is overwhelming. Her cock is aching to be satisfied, and she’s not wasting time.

Without a word, Emiri grabs Alice by her white lab coat, pulling her in close, and in one swift motion, she rips open Alice’s shirt. Her big, natural tits spill out, bouncing free, perfectly round and so fucking tempting. Emiri doesn’t hold back. She shoves Alice to her knees, pressing that big, throbbing cock against her lips. Alice, still wide-eyed, has no choice as Emiri’s dick forces its way into her mouth, filling it to the brim.

Emiri starts fucking Alice’s mouth hard, thrusting deep, her cock sliding in and out between those soft lips. Alice gags slightly, trying to keep up, her throat stretching to take the full length. Emiri can’t get enough of it, watching as her thick cock disappears down Alice’s throat, feeling the tightness of her lips wrapped around it. The more she thrusts, the more she feels that release building. With a loud groan, she cums hard, shooting a massive load of thick, hot cum straight into Alice’s mouth. Cum spills from her lips, dripping down her chin as she struggles to swallow it all.

But that’s just the beginning.

Emiri isn’t the only one getting in on the action. As Alice wipes the cum from her lips, thick, alien tentacles slither into the room, their slick, shiny bodies moving in fast. One tentacle coils around Alice, lifting her off the floor, while another thick cock-like tentacle pushes its way into her wet pussy, fucking her hard. Her eyes widen as the tentacle stretches her open, filling her completely. The sounds of wet, sloppy thrusts echo through the lab as the tentacle pounds her, juices dripping down her thighs.

Meanwhile, Emiri isn’t done either. She slides her massive cock between Alice’s big, jiggling tits, fucking her tits while the tentacle continues to ram her pussy. Emiri grips Alice’s tits tightly, thrusting her cock between them, feeling the slick warmth of her skin. Alice’s tits are slick with sweat and cum, bouncing with every thrust as Emiri’s cock moves faster.

A tentacle slithers down, its tip finding Alice’s mouth, forcing its way inside, fucking her face just like Emiri did moments before. Cum from the tentacle fills her mouth, spilling out as she moans around the slick cock. The room is filled with the sounds of heavy breathing, wet fucking, and the sticky slaps of cum-covered bodies.

But it doesn’t stop there. As Alice’s pussy and mouth are stuffed full by the tentacles, Emiri’s cock is throbbing again, ready for more. A new alien tentacle slithers over to Emiri, its mouth opening wide and latching onto her dick. The suction is intense, sending waves of pleasure through her as the tentacle sucks her hard cock with a deep, tight grip. Emiri moans, her back arching as the tentacle milks her cock, every inch of it throbbing as she gets closer to another orgasm.

The tentacles pump their thick loads into Alice’s pussy and mouth, filling her up until cum is spilling out everywhere. Emiri’s cock twitches in the alien’s tight grip, and with a loud moan, she cums again, shooting thick ropes of cum as the tentacle sucks every drop. Both girls are completely drenched, their bodies soaked in sweat and sticky, thick cum. Alice’s pussy overflows, cum pouring out like a fountain, covering the lab floor.

By the time the tentacles finally retract, both Emiri and Alice are left panting, their bodies drenched in cum, surrounded by the mess they’ve made. The lab is filled with the sweet stench of sex, and neither of them has any energy left to clean up. This mutation? It’s one wild fucking ride.
