I'm so freaking embarrassed....

In the span of two days both my brother and my step-dad have caught me masturbating. I'm so freaking embarrassed.... like I moved just in time for them for them not to say anything about it (I do it with my clothes on for this specific reason) but I know they know and I'm so so so embarrassed..... what do I do? I...ugh...I don't know anymore.....
