Yorihime woke up the next morning in a daze. Having witnessed both her Master and her sister having sex with Kars—and listening to her sister being fucked all night—she was exhausted. She couldn't believe Kars had that much energy.
The memory of her sister begging for mercy under his meat made her own body feel tight and uncomfortable.
The madness didn't stop during the day. As she turned a corner in the hallway, she heard Toyohime's moans again.
"Aaah! Kars... here... what if someone sees?"
"It's fine. No one but Yorihime-nee would care. And even though you say 'no,' your hips are moving plenty."
"Because I love Kars's cock too much... my pussy can't live without it..."
"Is that so? Then I'll give you even more! Take this!"
"Aah-oh!"
Yorihime heard everything. She was forced to realize that Kars had literally gone all night and was already starting again in the morning.
"Toyohime, let's walk through the hall while we do it."
"O-okay."
Yorihime ducked into a room to hide. Through the paper screen, she saw the silhouettes of her sister on all fours and Kars behind her, holding her hips like a wheelbarrow as they "walked."
When they reached the door of the room Yorihime was in, Kars stopped and began to hammer into Toyohime with brutal force.
"Aaah! No! I'm going again! Ah!"
Watching the shadows on the screen, Yorihime unconsciously began to rub her own breasts and pussy. She didn't find relief until she squirted against the floor.
When they finally left, Yorihime tidied herself up and stepped out, carefully stepping over the trails of love juices and semen left on the floor.
Over the next few days, she constantly ran into them having sex all over Eientei. Sometimes they were just on the other side of a thin wall, and Toyohime would even stick her head out to chat with Yorihime while she was being fucked. Yorihime didn't know what it felt like, but from her sister's face, it was clearly incredible.
One evening, Yorihime went to the outdoor hot springs for some quiet time. She had barely settled in when the door opened and Toyohime walked in, leading Kars by the hand.
Yorihime tensed up, wondering if they were going to have sex right in front of her.
"Sister, why did you bring Kars in here?"
"I couldn't help it, he's too clingy. Besides, he's just a child, it's fine."
How is it fine!? Yorihime wanted to scream. A guy who can have sex for twelve hours straight is NOT a child! But she couldn't say it. She watched as Toyohime washed Kars and sent him into the water before washing herself.
Kars swam over and sat right next to Yorihime. His gaze was fixed on her.
Yorihime shyly covered her chest. "What are you staring at, you little pervert!?"
"Because Yorihime-nee's breasts are so pretty. I can't help it."
At his shameless answer, Yorihime huffed and put a wet towel over her chest. But the wet fabric only made her pink nipples more visible. The "hidden" look was actually more erotic.
She noticed Kars's cock growing larger under the water. She couldn't look away.
"Yorihime-nee, do you like looking at my meat?"
"I... I don't..."
Yorihime looked away, but then she heard the water splash. Kars moved closer and placed his cock right in front of her face.
"What do you think of it, Big Sister?"
Being this close to the meat made Yorihime's eyes widen. She found herself wanting to take it into her mouth. Before she could decide, Toyohime's voice called out.
"Kars, don't tease Yorihime like that. Come over here."
"Okay!"
Kars turned and left. Yorihime felt a pang of regret. She watched as Kars hugged Toyohime in the water. It looked like a simple hug, but from the way her sister's legs were wrapped around his waist...
They were definitely fucking again.
