"Alright, let's go check on Sister Yuyuko. I wonder how she and Sister Yukari are getting along."
Kars supported the wobbly Youmu as they walked into the room where Yukari and Yuyuko were. As they reached the door, they were greeted by Yuyuko's lewd moans.
"Aah~ Yukari... harder... it feels so good..."
"You're getting more and more lustful, Yuyuko. I love you like this. I'm so glad Kars gave me his cock so I could educate your filthy pussy."
Kars entered the room to see Yuyuko on all fours, her butt in the air, with Yukari draped over her back. Their fleshy, rounded buttocks were pressed together, a sight that made Kars's cock jump. He wanted in.
He walked up and delivered a sharp slap to both of their asses.
"Ah!"
Both women cried out and turned to see Kars standing over them.
"I didn't expect to see Sister Yuyuko in such a state, being played with by Sister Yukari like this."
"Aah... because... because it's your cock... I couldn't refuse it... it's so much more powerful now... I love it..."
"Is that so? If you love it that much, have another one. Open wide."
Kars stood in front of Yuyuko and forced his cock into her mouth.
"Mghmghh!"
Yuyuko sucked greedily, her eyes full of happiness. She grabbed Kars's waist and moved her head rhythmically, desperate to drain him.
"You're like someone who hasn't eaten in days, Sister Yuyuko."
"I... I am! It's been so long since I've had your cock and cum. My body was reaching its limit, so give it to me~"
Yukari, watching Yuyuko lost in the blowjob, decided to be mischievous. She suddenly accelerated her thrusts into Yuyuko's pussy, causing Yuyuko's eyes to widen. The sounds of wet friction and flesh slapping filled the room.
"How can you ignore me, Yuyuko? I'm working so hard to make you feel good. It makes me sad. Master's cock belongs to me for now."
Yukari pulled Yuyuko's head back, removing Kars's cock from her mouth and taking it into her own.
"Yukari... you're so mean! How could you steal my cock!"
Yuyuko, unwilling to give it up, began licking the shaft and balls that were outside Yukari's mouth.
"There's nothing mean about it... I'll do anything for this cock. Ah... actually, rather than fucking someone else, I'd much rather be fucked by this thing myself."
Yukari was so distracted by the blowjob that she stopped moving her lower body. Her cock remained stationary inside Yuyuko, who pouted and began to grind her own hips to keep the sensation going.
"I'm coming... get ready!"
Kars ejaculated into Yukari's mouth. The massive volume overflowed, spilling from the corners of her lips and dripping onto Yuyuko's face. Yuyuko looked up, stuck out her tongue, and caught the stray drops. Yukari then leaned down and shared the remaining cum with Yuyuko through a deep kiss.
"Aah~ your cock... give me more..."
"You want more? Then let's try something intense."
Kars moved behind the two of them and aimed his cock at the pussy Yukari was already occupying.
"Eh? Kars... what are you doing? It won't fit." Yuyuko felt his cock rubbing against her entrance, which was already filled by Yukari's phallus.
"It won't fit? I wouldn't be so sure. After all, Yukari's cock is part of me."
As Kars pushed forward, his cock slid right through Yukari's, as if it were a ghost. Yuyuko screamed as she felt a second cock materialize inside her.
"Aah! No... not like this... it'll... it'll break..."
"We'll see about that! Here I go!"
The two cocks began to thrust in unison. The dual friction sent Yuyuko into a state of shock. Her pussy was being deformed and stretched from the inside, her body shaking so hard it felt like she was having a seizure.
With the two cocks working independently but in perfect sync, Yuyuko quickly lost her mind. She could only moan and beg for more.
"Look at you, Yuyuko. You're so irresistible when you're this depraved."
Yukari stroked Yuyuko's face and kissed her as the speed of the thrusts increased. Finally, both cocks ejaculated simultaneously. A massive flood of semen filled Yuyuko's uterus. Her eyes rolled back, and tears pricked the corners of her eyes from the sheer pleasure.
She was left on the floor with a massive belly, her pussy twitching and spraying out the excess cum.
