I like a boy and his brother too

I met the older brother first, I really felt a spark when I was with him, he'd make me feel so shy and I'd feel butterflies speaking to him. I think he liked me back too because he'd hint he did, but didn't outright say. I met his younger brother one day, who I thought was really sweet and attractive too, his younger brother told me the next day that he really likes me and wants to be with me romantically. I do really like his brother, but I don't know if I'm going to be able to hide the obvious attraction to his older brother if I speak to him.
