MIAD-972 My JK sister, Noa Eikawa, loves and caresses my morning wood like a pet, but she has no interest in me

A little sister who has no interest in her brother falls in love with his morning wood!? Deciding to keep his morning wood as a pet, the little sister comes to see him every morning, nuzzling his cheek, kissing his head, and even using her vagina as a house to insert it! Her brother acts cold towards her because he's a nuisance, but his morning wood is so cute she can't help but fall for him! In the end, she even starts to feel like a pet herself, putting on cat ears and indulging in his lower body! A love triangle of incest between a brother and sister!
