Doesn't quite fit... Probably it needs some context:

And a second one if I may:

You can ignore non-moaning SFX as people ignore them most of the time anyway, but if you still do want to translate them, here are two ways
1. Just translate the sounds as they are, like first one is Jyunn and second is Kuri Kuri
2. Use English movements, first one is like "lands softly", "press", and second is "twitch twitch" or "rub rub"
I would recommend you to ignore non-moaning SFX after all
