Yan!Wire and Killer seem like the two most likely to give their captive sweetheart an aphrodisiac with Wire mostly enjoying the initial struggle of them trying to fight it before they eventually break with Killer making them specifically beg to help them if they want any relief
TW: drugging
oh totally, both of them see absolutely no problems with using aphrodisiacs if gets them whatever they want and when they want it. it gives both of them the control they desperately crave all whilst they get to torture their poor sweetheart as much as they want.
Yan! Killer would crush it into the darling’s food right in front of them, then get a kick out of watching them eat it. he’ll sit and watch as they get begin to struggle to sit still and keep in any. then he’ll put up their plate and make sure to accidentally brush against them, asking if everything is alright when they quietly whimper over the interaction. he'll just sit there and continue eating his meal whilst the poor sweetheart is just panting, squeezing their legs tightly together and struggling to sit up right. Killer will just act as if they're not there and simply nod his head when they call out for him. he won't verbally or physically acknowledge the situation, just sit there eating and acting like this is the biggest waste of his time until they ask again. and then ask again. it's not until they're in tears and begging him to help that he's actually responding, asking why he should even bother since it's a waste of his time. Killer's not that much of a monster of course, he wouldn't leave them like this for longer than what he sees as being necessary but they need to remember their manners and beg him properly, telling him what he wants to hear in graphic details.
Yan! Wire would forcefully open the darling’s mouth and push it down their throat, forcing them to swallow it. he'll just stand over them just grinning whilst they start to dry-heave and cough, desperate to get the aphrodisiac out of their throat. Wire would make some smug comment about what he's just done and wish them luck trying to resist the effects. he would also definitely make a game out of how long they can struggle through the effects, promising them he'll give whatever they need and he'll be gentle with them (he's totally lying) if only they hold out just a little bit longer. all while there's a stop watch in his hand and he's using graphic, sexual language to rile them up further. then when they eventually crack, Wire will talk about how disappointed he is in them for not lasting longer. all while acting like their whines and desperate attempts to avoid giving him what he wants haven't made his shorts so incredibly tight. it's a shame they gave in so fast because they really haven't earned release yet but they're lucky Wire is so understanding. he'll offer his sweetheart the most embarrassing ways to get off, like humping his foot and talk about he's being so nice letting them earn what they want.
