Opening a gap behind her own butt, Yukari experimentally rubbed the cock Kars had given her against her anal opening. As she slowly pushed it in, she let out a long, shaky moan.
"Mmm~ this is a unique sensation... feeling a cock slide into my own ass... experiencing both sides of the pleasure at once is fascinating. My hips are moving on their own. Fucking myself is incredible..."
Draped over Kars's back, Yukari began to grind her hips wildly. She drove her own cock in and out of her rectum with increasing violence, falling in love with the sensation.
"Aah! So good! My ass feels amazing! Is this what you feel every day, Kars?"
"Your body feels great, doesn't it? Now that you know what feels good, move for me."
Kars slapped her ass, eliciting a joyful cry, and Yukari's waist movements became even more fluid and seductive.
"Aah~ I'm going weak... I'm going to cum..."
Her movements reached a fever pitch. With a series of mounting screams, both cocks erupted.
"Aah! Ohh!!"
Yukari's body shook in a massive climax. The cock in her ass continued to pump semen into her while she reached her peak. The dual sensation of climaxing and ejaculating simultaneously was overwhelming. Her eyes rolled back, and a lewd, tongue-lolling smile stretched across her face like a broken toy.
"Mmmph."
Yukari took both cocks into her hands and began licking them. One was her own, brought before her face via a gap, and the other was Kars's. She sucked both glans at once, saliva trailing from the corners of her mouth.
"Playing with you is always fun, Sister Yukari. These gaps allow for poses that would be impossible otherwise."
"Haa... if you like it, then play with me more. I'll agree to any request. I can't live without this cock."
"I know. Let's keep going."
Kars moved behind Yukari, making her present her butt. He drove his cock back into her semen-filled vagina. Yukari moaned with satisfaction, continuing to suck on her own cock as he worked her from behind.
Ran, having recovered, watched the scene in shock. She never expected to see her mistress in such a state.
"Lady Yukari... please put your cock in my pussy."
Ran crawled in front of Yukari, and they locked eyes. The cock from the gap was moved behind Ran's butt.
"Hehe~ let me show you some love too, Ran."
Yukari kissed Ran deeply, their tongues entangling as Yukari's cock slid into Ran's vagina.
"Aah~"
Both women let out lewd moans. Their heavy breasts swayed and collided with every movement. Seeing the two of them so depraved made Kars's cock even harder.
"The cock... how did it get even bigger... if this keeps up... my pussy is going to break..." Yukari felt the phallus inside her swell. Every time she thought she'd reached the limit of pleasure, Kars found a way to push her further.
"With you two looking so slutty, how could it not get bigger? It's your own fault, so use your bodies to make up for it!"
Kars accelerated his thrusts, his pelvis slamming against Yukari's fleshy buttocks.
"Yes... please use this filthy body to vent! My body exists only for Master's pleasure... aah!"
"Then take it!!"
With a final sprint, Kars ejaculated deep into Yukari's uterus. Her womb was already full, and the new influx of semen made the mixture incredibly thick, eventually plugging her cervix so nothing could leak out.
"Aah~ the cum... it's all piled up in my belly... I'm... I'm going to climax again..."
Feeling the immense heat inside her, Yukari collapsed onto the floor with a blissful Ahegao face. Her pussy continued to twitch and contract, unable to release the semen trapped inside.
"So, what does Master want to do next?"
Yukari and Ran both used their breasts to sandwich Kars's cock, massaging it while they waited for his next move.
"Next... let's go to the Hakugyokurou. I'm sure Sister Yuyuko would be happy to see us."
