How about the Sakamaki and Mukami brothers’ s/o letting them hang upside down from her finger while they are in their bat forms?

Admin Mawile: (*´・v・)

Shuu: He’s extremely likely to fall asleep there, and you might want to keep one hand ready to catch him when that happens. 

Reiji: It’s rather undignified to cling to you like he’s some kind of pet, and you’ll probably be sternly punished later to prove he’s still in charge. 

Ayato: He can’t stay in one place for long, and quickly migrates from your finger, to your shoulder, and eventually to your chest. 

Kanato: He’s a very prickly little bat, and intentionally pokes you with his claws just to see you squirm. Your pained faces are just too cute. 

Laito: Once he’s back in human form, he’ll have all kinds of nasty jokes to make about the incident, but he’s surprisingly quiet and still as a bat. 

Subaru: He’s very flustered by the whole thing, and tries not to look at you for too long, hiding behind his wings just to avoid it. 

Ruki: He doesn’t like feeling so small next to you, and will only perch for a moment. You can’t start thinking he’s anything less than your owner. 

Kou: He’s not fond of being in his bat form, and even less fond of you being so large and strong compared to him. He does not hang there for long. 

Yuuma: He’s big for a vampire bat, and you may not be able to hold him up for long. He doesn’t perching, though, and will stay as long as you can take it. 

Azusa: He’s happy to do anything that puts him close to you, and is very willing to snuggle up in your hand instead of hanging from it. 

for the xeno au: would the s&m boys act any differently to their bonded/attached s/o in terms of being sadistic to her? and if they she didn’t like it or smth (idk curious)

Admin Mawile: (๑´•д • `๑)

-That depends on the level of attachment. In extreme cases, massive behavior changes for the sake of pleasing and keeping the person the vampire is attached to can occur, but generally, the changes are much smaller and more subtle. Unconsciously, the vampire may begin to hold back or be more gentle with the person they’re attached to, but usually only on such a level that they’re hardly aware of it. If you’re extremely displeased by the rough treatment, though, that may be enough to scare some more gentle handling out of them, instincts protesting the very real chance of losing you. The individual vampire’s personality also must be taken into account, as more weak-willed individuals may give in to their instinct to please more easily. 

Xeno au! How do the boys react when another vampire tries to bite the person they’ve bonded with?

Admin Mawile: (・∧‐)ゞ

-That would be extremely upsetting for any vampire, and trigger a possessive sort of aggression meant to get the competitor to back off. Any vampire would be annoyed at the very least for something like that to happen, and most would be absolutely furious, driven by the desire to keep the one they’re bonded to. Trying to bite that person is a massive invasion of what belongs to them, and it’s going to very nearly end in a fight if the other vampire doesn’t back off. 

Are xeno au vampires behavior/moods affected by the person they bond with? For example, if they made them upset, would the boys feel especially bad? Or if their s/o is happy, would that also reflect in the boys’ mood? I love this au!

Admin Mawile: (´∀`) Thank you! 

-Yes, they do. It’s not exactly an automatic connection, though. The desire to keep the person they’re attached to happy is what causes it, an instinctive drive to keep the person who’s been kind enough to bond to. If that person isn’t happy, it could mean that they’ll leave,and thus the drive to fix that kicks in, spreading worry and doubt in the vampire’s mind until the person is happy again. If the attached person is, happy, the instincts are satisfied as well, content to know that they’ve done things right. It’s impossible for a vampire to be calm when they’re bonded to is upset, and in the strongest of attachments, that person’s happiness becomes the main cause of their own. 

Hello, in regards to the Xeno AU attachment instinct, I was wondering, would the attachment have any effect on the vampires wanting the person who they were attached to’s blood? As in would they be more likely to desire it or would it have absolutely no effect on that aspect of their psyche? Or would the response simply vary from vampire to vampire? Thank you, I hope you have a nice day! I simply love this AU 。^‿^。

Admin Mawile:╰(・∇・╰) Thank you!!!!

-Feeding involves a rather intimate connection, and yes, a bond would absolutely affect it. More so than craving the blood, the vampire would be more interested in the connection it can bring. Within vampire society, this effect has been almost erased from common knowledge, seen as weakness and something that should never be spoken of, so there would not be any awareness as to why the bonded person’s blood is so compelling. 

how would the xeno vampires react to forming an attachment with someone who wants nothing to do with them?

Admin Mawile: (´°ω°`)

-It would be extremely painful to be attached to someone and not be able to be close to them. Attachment demands closeness and contact, protection and deepening of the bond with the person that brought it on. Not being able to have any of this is practically torture, and would eventually escalate into mental agony so powerful it would become physical pain. Fortunately, it’s almost impossible to form that kind of bond without reciprocation, so that is a very unlikely event. 

What if in the Xeno AU their s/o gently and carefully massaged the base of their wings (or maybe other areas of them)? Would the brothers enjoy it and relax on their touch? (sorry,I got kinda curious about that (*´∀`*))

Admin Mawile: (。’▽’。)♡  Yes absolutely!!! The degree of relaxation would have more to do with each individual’s level of trust and willingness to show weakness, but from a purely physical standpoint, that would be wonderful. 

In xeno au, how would one meet a xeno vampire? do they live in houses or do they tend to make their own shelter outdoors? Also, where is the line between pleasure and pain when it comes to their wings? I know a gentle tap can be very painful or very pleasurable.

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.
