This is the beginning of one of my favorite HENTAiED stories, where Jia Lissa is trying to bring the existence of aliens into the light.
Her mission has consumed her life, and she finally brings an alien to Earth which we can fully see during this scene, making it a very exciting sci-fi experience where the sinful and the artistic mix, as this one has lots of cool effects, a straightforward plot, fantastic acting, and lots of tentacle play with Jia Lissa at the center of it all.
The aliens walk the Earth thanks to her efforts, and as a reward she gets to play with one of her beloved creatures after it escapes and accepts to acquaint itself with her in as deep a way as possible.
That is not the only alien, however, and soon they all spread all over the world, ready to mix with us and show us their strange and delightful capabilities.
The arcade machine alien attacks are by no means an accident, or in the case of the girls involved a lucky occurrence. They have all been orchestrated by Jia, who has been enchanted by alien cocks for a long time now. She’s always searching for new ways to recreate them, tame the monsters of darkness, and use them for her own pleasure.
