Help me what should i do?

M (30) I have always found my older cousin very attractive f(45). She has an amazing body, tits and ass last time I went to her house she was cleaning had these booty shorts on and bent over and I seen her ass. I want to make a move but don’t want to ruin things or make it awkward. What should I do? If anyone been in this position how did you guys go about it and did it change things or make them awkward?
