Relaxing in bed, the daughter suddenly started licking her mother. With no choice, the mother put on a mask and began filming. "Ahhhh... so good, so good, so good!" "Ahh, it feels so good, ahh~" They continued enjoying themselves for a while, when Eriana appeared. She wore black gloves, her fingertips rounded—likely hiding vaseline. To check the anus, she spread apart the daughter's plump, juicy buttocks. Then, aiming precisely, she thrust in—pssst... Daughter: "Nnnnnnnnnnnnnnnn!" The black glove began churning inside the daughter's anus. It seemed like her fingers plunged deeply, all the way to the core. The daughter flailed her legs, moaning in ecstasy. "Aaah—uuuuuuuuu—" So fixated on her own anus, she completely forgot about licking her mother. The mother's moans gradually faded. "Aaah—aaaah—aaaah—aaaah!" "Eyaahhh—aaaah—no no no no no!" "Aaah—aaah—aaah—aaah—aaah..." For some reason, the daughter began convulsing. Eriana continued relentlessly, stirring deep inside her anus. "Aaaauu—aaaauu—aaaaauu!" "Aaaaaah—aaaaah—laaaameeeee!" The daughter was screaming so wildly, there was no way she could focus on clitoral licking anymore. "Aaaaaaaaaah—no no no no no no!" By now, the mother had already climaxed. Mother: "My butt?" Eriana: "Your butt, lol." Could it be? Was she planning to turn the daughter into an anal daughter, just like the anal mother? "Haaaaaaa—haaaaaaa—" "Haaaaa—ah—ah—no, no, no!" "Aaaaaaaaaaah!" The anal stimulation was too intense—something was beginning to happen. Though invisible from the outside, judging by the daughter's condition, something extreme was clearly occurring inside her anus. Eventually, the daughter tried to flee, but Eriana's finger refused to come out. No matter how far she ran, Eriana's nuclear fusion accelerator remained firmly embedded in her anus. "Haaaaa—oh haaaaa—oh haaaaa—" Soon, the daughter ran completely off-screen, yet the accelerator stayed inserted. Only when she ran even further did the finger finally pull out... Wait? Did nuclear fission occur? Then, dragged back onto the bed, the accelerator revved up even more intensely. "Haa-ah-ah—haa-ah-ah!" She bounced and screamed wildly on the bed. The daughter was now completely unhinged. Finally, Eriana pushed a silicone dildo attached to her crotch deep into the daughter's anus. Was she attempting to control the fusion reaction of protons and neutrons within the intestines?
