[Shiina Kazuki] Isekai Shoukan 4 Ch.1-4 [biribiri]

Summoned into a strange world, a lone male hero is immediately embraced by a seductive harem of kemonomimi women who claim him as the centerpiece of their polygamous family. As they argue over his fate, one reveals a body‑modifier that inflates his assets to impossible size, while another threatens to exploit his new form for her own pleasure. The tension escalates when mind‑control tactics and the looming influence of a brothel threaten to reshape his identity and force an intense, erotic confrontation.
