sinday headcanons. nsfw under the cut, this is your warning.
guizhong's a switch. what's most important to her with sex is everyone having a good time - she can enjoy any role, so she'll just match her partner.
that being said, if you try to be Serious with your domming she will probably start laughing at you. she's not trying to be a dick, but if you're someone she wants to sleep with she will not be able to take that seriously.
...she'll also probably start laughing at you if you get flustered by her domming.
actually, if you fuck her without her laughing at some point, something's probably wrong.
she loves sensory stimulation. whether that's being touched lightly, being held down or something like temperature play, she'll turn to putty pretty quickly if you do something that hits her right there.
her hands and shoulderblades (where her wings would come out) are particularly sensitive. she also likes having her hair stroked.
if she's domming, she'll be talking to you constantly. she's primarily doing this to make sure she's checking in with you. like i said - the most important thing is to make sure her partner is having a good time, so she will be very tuned into you and if she notices so much as a hint of discomfort she's going to be making sure everything is fine before she continues. she's very attuned to how her partner feels, even during the times where she's trying out a 'meaner' persona.
she won't use euphemisms and doesn't really 'get' the social taboo of talking directly about sex. she won't talk about it in public, but if she wants to have sex and you have that kind of relationship with her, she's likely to just straight-up ask 'so, wanna have sex?'
while she doesn't get the taboo, she is aware that some people will become flustered if she explicitly asks. she'll act all innocent, but sometimes her forthrightness is very purposeful. she thinks she's funny.
she'll laugh at you if you try to do it back to her.
she's more vanilla than she is kinky. she'll dom or sub and she'll play into some kinks. she'll also be open to kinky things if her partner's into something, with some exceptions. but ultimately her favourite thing about sex is the intimacy and feeling of closeness with her partner. other things can be fun, but that's what she's here for.
