@Draugoth there is already an english version on dlsite
but basicly The heros of the story go in to stop this alien? horde , after kicking ass for a little bit they go deeper into the enemy base. The leader (chick with the huge weird pig tails sorry i dont know what they are called XD ) is captured and tortured for information by one of the higher ranking aliens. This torture consists of being sucked by some weird leech, getting gangbanged by aliens, getting her limps chopped off, and giving birth to monsters. All of this happens while she is having beyond human levels of orgasmic pleasure because of some drug that the leech put into her. The ending is a cliff hanger where the higher ranking alien finishes interrogating her and leaves her to be gangbanged by more aliens while he goes to tell his superiors the news of intruders. The leader being the blue lady with red hair, and another being like himself that seems to like using his victims like punching bags.
And yea thats the summary, sorry for my terrible writing in advance.
