Pred and prey that are mutually reluctant because they've both had bad experiences in the past, the prey with nearly being digested by someone she loved and the pred by being BADLY hurt internally (like a broken rib or two) maybe because a prey forced themselves down the pred's throat and their body wasn't properly adjusted.
They're kind of an unlikely duo; the prey is a no-nonsense, serious workaholic kind of person while the pred is a lot more laid back, always cracking jokes, always giving people friendly smiles. Somehow, it just works.
But there's also a sort of tension; there have been moments where one stares at the other for a little too long, pondering, wondering how it would feel to be... closer. Neither of them say anything about the underlying tension between them.
It happens suddenly. They go home together after a stressful day, and they realize how much they love and need one another. It's almost magical; the prey pulls the pred down by her collar and they share a kiss. The pred's tail flicks back and forth excitedly, and she purrs, while the prey's face flushes red. They pull away for just a second, staring at each other. Then, the prey's eyes flicker down to the pred's mouth, to her teeth and tongue, and into the dark abyss that's her throat...
They don't need to exchange any words. Not now. The pred's face turns bright red, but she opens her mouth, guiding the prey in. They're both a little nervous and awkward, and the prey thinks she can even feel slight shivering from the pred, and when she does, she idly thinks, oh, that's right, she had a bad experience last time, and while she thinks, the pred makes the first swallow.
The experience is wildly different this time. Last time, the prey was fighting to escape, screaming for help. Everything about the situation last time seemed terrifying and was violent.
But... not this time. This pred's body is soft and gentle, almost even uncertain, as she tips her head back and lightly swallows the prey down. It takes a few swallows, but after a few moments, the pred's got the prey tucked away, and she's left breathing heavily as she gingerly runs her clawed fingers over her stomach. Now, it's the pred's turn to notice the prey's shivering, and she remembers: the prey has a scar on their body somewhere from the last time a pred got her.
But this time will be different. The pred will keep her safe, and she trusts the prey to not push the pred's body past its limits.
Right now, though, the pred feels like melting onto complete bliss. She had no idea it could feel so nice to have a meal like this...
