Simple, tell him and suffer the consequences or
hide this from your brother and live with the guilt.
That last bit is probably the best advice I've gotten so far, and I also thought of that.
She approached about keeping it secret, and since I obviously don't want to be on my brother's shit list for any extended amount of time, especially since he would probably kill me in the literal sense, I agreed completely, and decided that whenever she had 'incidents' like this in the future, I would lead her to their room and leave her in her bed, and then leave the house, regardless of what funny business might occur.
No more sex with her, this is going to be a one time mistake.
Living a clean, honest life never suited me anyway, so honesty about one thing will lead to honesty about other things I don't want people to know about. She agreed that this would not happen again, and I agreed to keep it a secret from my brother by any means necessary.
Hopefully, I can put this behind me for years to come and live happily ever after.
