"Aunts!" Seeing Remilia and Flandre arrive at the Palace of the Earth Spirits, accompanied by Sakuya, Kars happily ran to Remilia and hugged her.
"Hmph~ You're happy to see me, yet you haven't bothered to come home." Remilia was pleased with Kars's reaction, but she was also unhappy with his habit of being so absorbed in playing with girls outside that he didn't go home.
"That's right. Flandre thinks about Kars every day. Did Kars miss Flandre?"
"Well… I called you over to play together because I missed you." Kars looked a little guilty. Remilia, seeing his demeanor, sighed softly, clearly already knowing the situation.
"Alright, alright, it's my fault, Aunt, don't be mad." Kars said, kissing Remilia's lips. Their tongues quickly intertwined, and his hands were already touching, rubbing, and stroking Remilia's buttocks.
"So, you wanted us to play together this time? All sisters? You really know how to have fun." After learning Kars's intentions, Remilia gladly accepted and immediately stripped off her clothes, as if to show Kars something.
"Eh? What is this?" Kars noticed a pattern on Remilia's lower abdomen that wasn't there before. It was pink and glowing, looking very beautiful.
"Doesn't it look good? Patchouli did it. She said that drawing an Arousal Mark on the body would make you like it more. So now all of us have this Arousal Mark on our stomachs." Hearing Remilia say this, Kars looked at Flandre, who was also undressed, and she indeed had an Arousal Mark. Even Sakuya lifted her shirt to let Kars see hers.
Seeing this, Satori looked at the words written on her own stomach and suddenly felt a little annoyed. Others had beautiful Arousal Marks drawn on them, while hers had some unremarkable writing.
"Hurry up!" Flandre couldn't wait to have sex with Kars. After pulling Kars onto the bed, she immediately pinned him down, then leaned in and began to lap at his cock.
"Kars's cock is different now, but Flandre likes it even more!" Flandre held Kars's cock with both hands and began to enthusiastically perform oral sex. Kars also asked Koishi to join Flandre in giving him oral sex. Meanwhile, he embraced Remilia and Satori, and the three of them began to French kiss with their tongues.
"My aunt's nipples are still so pretty, and have they gotten a little bigger?" Although she was still flat-chested, Kars could feel that her breasts were slightly more prominent than before. Biting onto her pink nipple, Kars began to suck forcefully.
"Hmm~ You really are like a child who never grows up." Kars enjoyed the taste of Remilia's nipple, while his hands reached under both her and Satori's bodies, thrusting his fingers into their already wet pussies.
The two women's breasts were sucked in turns, quickly becoming firm and somewhat swollen, which made them even more attractive to Kars.
"Your cock is getting harder and harder. It must want Flandre's pussy. Flandre will put it in now. I wonder what Kars's cock feels like now." Flandre licked her lips and squatted on Kars's body. After rubbing her pussy gently against the cock, she plunged the cock entirely into her pussy in one go. The swelling of her abdomen from the thick cock could be seen.
"It's so big… Flandre's pussy… feels like it can't fit it all… and it's more comfortable…" Flandre twisted her waist, letting the cock churn back and forth inside her pussy, as if familiarizing her pussy with this completely different cock, before she started moving again.
The cock struck her cervix repeatedly, causing Flandre's moans to become incredibly loud and satisfied. With a lust-filled smile on her face, she quickly moved her hips, letting the cock fiercely thrust her pussy. Koishi leaned over, lapping at Kars's cock and Flandre's asshole, subtly providing both of them with some added sexual pleasure.
"Kars, look… Flandre's Arousal Mark is getting prettier." As her body became more excited, the Arousal Mark on Flandre's abdomen glowed and slowly expanded, transforming into a pattern similar to a uterus. This large-area pattern added a unique charm to Flandre's body.
Kars, seeing this, wanted to see if the Arousal Mark could become even prettier. Amidst his fierce thrusting, the cock pressed tightly against the cervix, causing the opening to widen. Semen quickly surged inside, filling Flandre's uterus and making her belly swell slightly.
After receiving the semen, the Arousal Mark on Flandre's abdomen glowed brighter, and Flandre let out a more seductive moan. Her small, bun-like flat breasts transformed to the size of apples. This unexpected change was surprising, and then white milk slowly flowed from her pink nipples.
"Oh! That's amazing!" Koishi was instantly astonished, having never thought that something like this could instantly produce milk in someone's breasts. This made her want to try it too.
"Flandre's breasts… feel strange…" Flandre squeezed her now-larger breasts. This action caused the milk to flow out even more heavily. The rich milky scent made Kars unable to resist leaning in, biting down on a nipple, and sucking the milk.
"Hehehe~ Kars is a baby now, drinking mommy Flandre's milk." Flandre happily held Kars's head. A hint of maternal quality appeared on her, which, combined with her loli image, made Kars even more excited. He also looked forward to tasting Remilia's milk as well.
