The yuthful[sic] uke featured on the cover is actually more masculine in plot, and this is even bara-ed up in the extra chapter (super tasty!) The story is just sex demons outbeating the next as it showcases delicious scenes. This manga was super smutty yet pretty funny.  It's a shame there wasn't much versitility but the last scene with the brothers' ukes was top notch.
