"Let me take the next one," Eirin said, seeing Yuuka was at her limit.
Eirin arched her back on the bed, presenting her butt. Kars slammed into her. Under Eirin's expert internal control, her vaginal walls undulated and squeezed his shaft. The sensation was so intense that Kars began to hammer her with reckless abandon.
"Ahhh~ Kars... hurry... shoot it... fill me up... don't stop pouring it in~"
"I don't need to be told! I can't hold back in a hole this good! Lift your butt higher, I'm going all the way in!"
Kars threw his full weight onto her, pinning her down as he jackhammered her. The sound of their bodies colliding was broadcast in high definition. Every woman in the audience was now masturbating furiously, wishing they were the ones being pinned.
Kars ejaculated again, and Eirin's belly distended even further than a full-term pregnancy. She lay there, trembling, using every muscle to keep the semen trapped inside.
Ran took the final shift, extracting the last possible drops before the timer hit zero. The three women, all sporting massive "cum-bellies," walked over to a glass vat. They relaxed their muscles simultaneously.
The sight of the thick, white fluid geysering out of them and filling the vat left the audience—and Tsukuyomi—speechless. Their faces were locked in a blissful ahegao as the pressure finally left their bodies. They had filled a massive container to the brim.
"The pussy is truly the best vessel for semen," Yukari remarked triumphantly. "It shows how much we love Kars's seed. That was quite a rush, wasn't it, ladies?"
Tsukuyomi's face was pale. To win, her team had to use the same method. But there was a problem: the Lunar representatives were already pregnant. Using their wombs as storage vats for an extraction competition was physically impossible and potentially dangerous for the babies.
"There's no need for that," Kars intervened. "Tsukuyomi and the others can't do that right now. We can use a different method."
Kars wouldn't allow his pregnant wives to put themselves through that. Yukari didn't argue; she wouldn't go against Kars's direct wishes.
"Kars..." Tsukuyomi looked at him with adoration, touched by his protection.
However, despite Kars's mercy, the Lunar team lost. Without the "internal storage" method, they had to pull the cock out to shoot into containers. This lacked the intense stimulation of a tight vagina, meaning Kars produced less volume and took longer to recharge. The Lunar Capital was utterly defeated.
"We won!!" the Gensokyo girls cheered.
Though defeated, Tsukuyomi and her sisters were quickly comforted. Kars spent the next few hours fucking them all, replacing their disappointment with mindless pleasure.
The time for departure arrived. The Moon was sad to see their King leave, but Yukari promised a permanent portal would be maintained. After one final, massive orgy that left the Capital covered in semen, Kars finally returned to Gensokyo.
