I give it a 3. The plot was SO much fun abeit a lil unnecessarily smutty. Smut for smut sake isn't really hot it kinda just cheapens all the sex cause it's just THERE. So, 4 *. Then the super femmy dudes....not my thing at ALL. So 3*.
But, for anyone else turned off by the girly dudes the mangaka clearly did their research for BDSM. You can tell by the way they handle the 3way relationship and some of the scenes. Just a shame the art was practically yuri.
