One day, I suddenly got a little sister by marriage, Hotaru-chan... she's a giant-breasted sex monster!? A well-built girl appeared in the house full of men, making me and all the other guys super excited!! Peeping, voyeurism, sexual harassment! Hotaru saw through our lecherous gazes and counterattacked! She sucked my dick on her own... had sex... to deepen familial love, we all happily engaged in group sex with internal ejaculation... Every day, we're used as masturbation material and fucked to death. Our family's bodies are getting more and more erotic, and we can't stop getting hard and ejaculating...!
