mmmmmmsam and darlin and they both have a voice kink (mdni)
for darlin it’s that growly grumbling, the way his voice rattles around his chest before escaping his lips, the way he says certain things, like calling himself daddy (ie “oh you like when daddy does that?” “you gonna do (blank) for daddy?”)
for sam it’s the familiarity and desperation in darlin’s voice. i think they can be tough as nails and stubborn and whatever but they definitely get all melty and whiny and needy when sam gets that tone with them or when they haven’t seen him in a while
and i know just a casual phone call has devolved into panting and moaning into the speaker for both of them. like, one will just be carrying out a conversation about their day or something non-consequential and they’ll ask a question only to be met with a choked response and rustling of clothes as the other tries to get off without being noticed
or especially shamefully, they’ll be loud on purpose, announce what they’re doing (“you hear what you’re doing to me?” “fuck keep talking”)
idk just food for thought
