"Ugh I don't understand how you were born with such measly tits when I was granted these beauties~!" Junko said as she poked Mukuro's chest, making the girl jump. This wasn't the first time the soldier had heard such a thing of course, but it was the first time Junko had gone so far as to touch them, even with just a poke.

"I-I don't know either…" She said, never able to speak very loudly near her sister. "I just—AHH!" She cried out as Junko placed both hands over her breasts completely, squeezing them.

"I mean what man would want these tiny tits on top of your already butt-ugly face?" She asked.

"I…I don't think…" Mukuro tried to say, but she stopped when Junko ripped open her shirt without warning, even pulling up her bra to allow her breasts to be completely exposed, her pale nipples hardening from the chill of the room, even as her face turned a deep red. "J-Junko! What are you—AHH!" The girl jumped again as Junko put her hands on her sister's bare chest.

"Hmmm…they're not even that soft! Man, how is it that you fail in every way?" She asked, pinching her nipples between her fingers and pulling, making Mukuro moan as her body shuddered. "Hopefully if you do manage to find someone, they'll appreciate your easy reactions." Junko scoffed. Mukuro wanted to speak, but was unable to as she felt herself becoming turned on by her sister playing with her nipples like this. So when Junko let go, it was almost disappointing, though it allowed the soldier to catch her breath. "Maybe you should get some breast implants! Then maybe you can at least somewhat reach this level!" Junko exclaimed as, without warning, she grabbed Mukuro's hands and shoved them against her own chest.

Immediately, Mukuro gasped as her hands sunk into the soft mounds even through the fabric covering them. Junko laughed at her expression. "Hahahahaha! What? Can't handle your sister's chest? Or are you getting turned on by them, you sick pervert?"

"N-no! That's not-" Mukuro tried to defend herself, but Junko practically ripped open her own shirt, tossing away her bra and leaving her nearly topless in an instant, her large breasts bouncing free in front of Mukuro's face. The sight of them, of Junko's seemingly perfect chest and gorgeous nipples, made the soldier instantly horny.

"I knew it. You incestuous freak!" She yelled with a laugh as she grabbed Mukuro's hands again and placed them against her chest. Mukuro moaned again as her hands sunk in even deeper, surprised by just how soft they actually were. She felt her body shudder when she saw Junko shake as she brushed her nipples. She squeezed the breasts, her hands unable to cover the entire thing as Junko laughed and laughed. Mukuro felt ashamed of herself. Junko was right, how could she get turned on by her own sister?! But as she was mentally berating herself, she was surprised as Junko pulled her close and kissed her. Mukuro went wide-eyed and groaned, then moaned as their chests touched, their nipples rubbing together, stimulating her further. Her lips were warm and rough as she kissed her intensely, but only for a few seconds before she pulled away.

"Incest…such a despairful thing." Junko said, smiling. "When two people of such close relations come together, they violate the law of society. They can even sometimes come to create an abomination of a child, a child that society pretends to care about, but would rather they didn't exist, and just put on a face of trying to "help". What a pitiful lie from all of society as they secretly belittle and treat these abominations as the lower life forms they are. Ahhhh…but even so…if it's between two men or two females…though it's still shunned as taboo, even so they can do it with almost no consequences! How…beautiful~" Junko went on with her monologue with a dreamy smile on her face as she stared at Mukuro's chest. "And to do it with someone as hideous as you…that is such despair~"

"J-Junko…?"

"AHHHHH!" She yelled as she tackled Mukuro to the floor and quickly ripped off the rest of her clothing, attacking every inch of the soldier's skin with her tongue and her hands. While Mukuro fought back at first, she eventually realized…Junko hated this…which meant she loved it. It didn't make sense, but that's just how she was, so she simply let it happen, and tried to enjoy herself as Junko hate fucked her sister all night long, in the name of despair.
