[Daijobi Kenkyuujo (Lobster)] Indecent Days of the Mareinu Kingdom

Young knight Flam returns from his mission expecting a hero's welcome—instead, the Mareinu Kingdom's insatiable women ambush him at every turn, from busty clergy greeting him at the gates to an older seductress who milks him into submission with her huge breasts. This realm under Holy Church protection hides a shameless secret: its priestesses and dark-skinned demon girls treat daily debauchery as divine duty, riding the young hero until he's ahegao-faced and emptied. As stomach-deforming, cervix-penetrating intensity builds toward impregnation, Flam learns that serving the kingdom means serving every hungry womb in it.
