Admin Mawile: (ᅌᴗᅌ* ) Ooooh nice questions!!!
-Xeno au is mostly the same as canon, save for vampires and other creatures being much less human. The set up is the same as canon still, and vampires are really more like monsters masquerading around in human skin than humans that just happen to have powers and drink blood.
-A lot of what determines whether a touch is painful or pleasurable is intent. A cruel tug is going to feel very different than a light, loving one. The vampire’s state of mind can also trick them into them into feeling pain; if they’re afraid, anything short of absolute gentleness can hurt. Finally, personal preference means a lot. Someone like Azusa will enjoy yanking and pinching, but more delicate vampires would find it excruciating.
