Junko drugged Mukuro's tea she was having the first evening after they began Junko's plan of starting the killing game to spread despair among their beloved classmates. Mukuro wasn't aware of that fact and simply went back into her dorm, thinking she was just sleepy, and she fell asleep on a completely uncomfortable bed. Oh, well, it was still better than the ones on the second floor that was now destroyed. Enoshima left the lab she was hanging out in, earlier making sure that everyone was sleeping. In the other hand, what despair would wait for her if she was caught on her way to fuck her ugly twin sister? The thought of raping Mukuro was already giving her a lot of despair. She used the master key and sneaked into her sibling's room. Mukuro was indeed asleep and didn't look like she would be easily awakened. Perfect.Seeing the SHSL Soldier being so defenseless was a rare view that Junko adored. How much despair would she give to her beloved sister when she would wake up with her body so exposed, with her come dripping out of her? Junko never used any condoms, knowing that there was no way to get her twin pregnant. How despairful. Junko opened Mukuro's shirt, ripping the buttons out and noticed that she was wearing no bra under it. Maybe she missed the moment of her taking it off. Or maybe was she a slut? Did she want to impress someone else, that wasn't her? “Oh, Mukuro, you're such a bad girl,” she mumbled to herself and took a bottle of lubricant that was kept in one of the drawers. She opened it and squirted on her already stiff cock. Would it give her more despair if she later watched the tapes from the surveillance cameras? It was easy for Junko to predict that Mukuro was going to betray her.Using one hand, Enoshima spread the gel on her member and with another, she lifted her sister's skirt up and moved her panties aside, exposing her vulva. She was obviously dry, so not using any lube wouldn't be a nice thing. Even Junko, who wanted to spread despair everywhere and to everyone, wouldn't do it without any lubricant. She didn't even care to play with her twin. Instead, she pushed her dick inside her. “You're so loose,” she lied. Mukuro was really tight every time she raped her and she thought how great idea it would be to show the record to her sibling. It would bring a lot of despair to Ikusaba if she knew what her little twin was doing to her since they got rid off of the headmaster and Junko was the one making the rules in the academy.
Having to lube her sister during the act was making Enoshima feeling so hopeless, but at some point Mukuro's vagina started moisturizing itself. It was a simple reaction of the body, while Mukuro herself stayed unconscious.
Junko exploded inside her sister, filling her with come that she couldn't impregnate her with. She didn't know what was more despairful – the fact she couldn't get Mukuro pregnant, or her fantasy of ruining her older twin.
Enoshima used her sister's skirt to wipe her cock before going to take a shower in her bathroom. She left there so many products she was using and though it was just the beginning, her twin used a half of the cosmetics. It made Junko wonder if at any point of them staying in that hopeless place, Mukuro wanted to be fucked by her sister but would never dare to ask for it.
Trying not to make noise, Junko left the area of the dorms and then sneaked back into the place she could watch everyone from. It was so boring that nobody didn't kill anyone yet, but she had an idea how to convince them. The motive was going to be simple. Junko grinned to herself.
