[Itaba Hiroshi] Shinseki Midara My Home Harem Ch.1-5 [castor translates things]

Shuu-kun's quiet life is upended when his sister leaves her daughter Rin in his care for an overseas business trip, and his house suddenly fills with voluptuous relatives eager to claim the sole male for themselves. Busty, beautiful Midori nee-chan, a bold gyaru and affectionate younger cousins in lingerie and schoolgirl uniforms compete shamelessly, turning everyday family moments into flirtatious group seduction filled with sweet defloration, deep creampie longing and lingering inverted-nipple teases. As each chapter raises the stakes, the tender harem grows more possessive and insatiable, leaving him caught between domestic routine and the irresistible pull of his new home life.
