As others have mentioned before; inexperienced pred/prey.
Inexperienced preds that are a bit hasty are just peak, or even just hasty ones. Like a pred who’s never vored anyone before but desperately wants to eat their friend and it consumes his mind every time he looks at him, mouth filling saliva at the mere thought. When his friend sits upon their palm he gets practically chucked into his mouth at the sheer speed and immediately swallowed. The shock takes what feels like a minute before he realises his friend just fucking ate him without a second thought. Oh, the options!
Prey is just damn cute. Full of nervous energy trying to sake his mate to eat him unsure that he will even understand his request let alone his feelings. Adorable imo
