Kusurizuke Kyonyuu Celeb Fujin Kankin no Kiroku

Through a series of events, the protagonist landed himself a sweet apartment in
the 60 storey high rise of Tokyo's elite residential district of Sanzenongi Hills.
The day he'd moved in he met a gorgeous housewife in a very flattering, come-hither dress.
Her name was Reika Sanzenin. Tight waist. Sultry hips. Perky, youthful, smoldering breasts.
She was a goddess.
And she owned the building.
