Mm, hihihi...♥ Getting into it, right? You won't mind serving as an outlet for my lust, right?

думаю, надо предыдущее предложение, а не последующее.

If at first you resistant to something and then you start enjoying it we say you’re “getting into it“. In this case, it sounds like the speaker is subjecting someone to rough sex, which they didn’t seem to enjoy very much at first, but now they’re starting to get into it.

То есть это можно перевести как "Включаешься в игру/процесс" ?

Не думаю

Входишь во вкус
