Emiri Momota is a simple cleaning lady at a scientific laboratory, her days are not really filled with excitement but she does her job more than well. She’s at the laboratory every night, cleaning behind the docs and scientists who usually don’t make a lot of mess. Today it’s everything as usual, she’s got earphones, listening to music, and cleaning one of the laboratories. However, one of the chairs is extremely slimy. There’s a trail running down it, which she tries to wipe off but it’s sticking to the cloth. It’s disgusting but she keeps wiping even harder, fully focused on the problem at hand while a danger appears. All over the lab, a bunch of alien tentacles crawls over the floor, all around Emiri, approaching her for an ambush. She’s done with the cleaning, the seat is spotless, and just in time. Alien tentacles wrap around her ankles and neck, planting her on top of the same chair, and holding her still in place. Her white panties are peeking under the skirt as she’s fighting for breath. The tentacle cocks get all over Emiri, they start undressing her, taking off her skirt and top, revealing her ample breasts, and then ripping off those silky white panties to reveal a tight bushy slit. The tentacle around her neck clenches harder so she would stop fighting back. There’s no reason to fight, her efforts are wasted and she’s only spending much-needed energy for nothing, so Emiri stops. She’s laying there naked, waiting for the next move from her captivators. A couple of suckling tentacles appear. They latch onto her tits, right above the nipples, and start sucking them while Emiri wriggles in newfound pleasure. She’s moaning in her squeaky voice and whispering something in Japanese. Then in the midst of her pleasure, a tentacle cock sneaks up inside her pussy. Emiri gasps, surprised by the thickness of the tentacle cock inside her, and her eyes start rolling back into her head. The surprises never come to an end with these horny aliens.
