When an omega is stressed, worried, or in heat, their alpha can lay on top of them or cuddle up to them and purr, soothing their omega with their rumbling purr.

Ghost has never done that. He doesn't know what his purr sounds like. He hasn't ever felt the need to purr, having never claimed an omega.

Until you.

He met you when you joined their team. An unmated omega like you would quickly get yourself into trouble with the other alpha's on base so he always stood by and protected you, eventually growing closer and ending up with him claiming you.

Now you're his.

It's been a long day, Ghost can tell by the change in your scent as he stops outside your barracks. He's immediately protective, bursting in and spotting you laying on your bed.

He walks over and drapes himself over you, laying on top of you and damn near squishing you. Then, he starts purring. A rough, deep growling sound at first, sounding more like a stuttering engine starting, from lack of use, before settling into a low, rumbling purr.
