"You two have been hogging Kars for far too long, haven't you?"
Eirin Yagokoro looked at her two disciples. They were completely addicted to Kars's meat, and their constant monopolization of him was starting to test her patience.
"Well, Master, you did lie to us and say he was your son," Toyohime pouted. "Then you had him tell me to be your daughter-in-law. That was quite mean."
"Besides," Toyohime added, her hips still grinding as she sat on Kars, "Kars doesn't want to leave our pussies. He wants to keep planting his seeds until we're pregnant, right?"
She looked down at Kars, who was currently busy eating out Yorihime while Yorihime sat on his face. The sight filled them both with happiness.
"If that's the case," Eirin noted, "you're likely already fertilized. With Kars's potency, you'll definitely conceive."
"Really? I'm going to be a mother soon? I'm so happy!" Toyohime's excitement translated into faster hip movements, her moans turning into high-pitched shrieks as the cock hammered her internal walls.
"Ah! Kars... come back to the Lunar Capital with us! I can't imagine life without you. If we go back alone, we'll die of withdrawal!"
"I can't just ignore that," Eirin interrupted. "If you take him to the Moon, what are we supposed to do down here?"
Eirin flatly refused the idea of her disciples "kidnapping" Kars.
"Besides, Kars might not like the Moon. It's not as free as Gensokyo. Here, we can have sex whenever and wherever we want. You can't do that up there."
"We... we'll find a way! Master, please! Just for a little while! We can't be apart from him..." Toyohime pleaded. To go back now would be a death sentence for their libidos.
"The choice belongs to Kars, not me. What do you think, Kars?"
The two sisters looked at him with desperate, pleading eyes. "Please, Kars! Just stay with us for a while. we promise we'll make sure you're never bored."
Kars thought about it. He knew nothing of the Lunar Capital.
"Kars~"
Seeing their hopeful faces, he couldn't say no. "Alright. Just for a little while."
"Thank you, Kars!" They both kissed him deeply, their tongues intertwining in a messy, desperate display of affection.
Eirin sighed, then began to slowly strip off her clothes. "In that case, give Kars to me now. If he's going away for a while, I need to make up for lost time."
"Ehh? Master, you've had him this whole time! Don't steal him from us now!"
"This is different. There's no rule saying I have to share just because I've had my turn." Eirin spread her legs in front of Kars and began to masturbate.
"Look at me, Kars. This slutty hole is waiting for your meat. Shove it in and turn me into your moaning sex slave~"
"Ah! Kars! No fair! I was almost at my climax!" Toyohime cried out as Kars pulled out of her and slammed into Eirin. Eirin flashed a victorious, depraved smile at her disciples as she gave herself over to the pleasure of the cock.
"So you were all keeping this from me!"
"Princess!?"
Everyone looked up to see Kaguya Houraisan standing there. Eirin realized she had forgotten about Kaguya, and seeing Tewi Inaba snickering nearby, she knew exactly who had ratted them out.
"Kars! You were going to the Moon without telling me? Without considering my feelings!?" Kaguya looked distraught, but that expression was quickly replaced by an orgasmic flush as she joined the unfolding orgy.
