My(24M). Aunt 44F keeps complimenting and coming close to me, especially after my fat loss.

One day, she saw me naked while bathing, then has started becoming touchy.

Then from next days , she has become friendly, touches me on my waist, we never talked about the voyeurism by her Keeps on having long lingering touches on my waist

How should I approach this one is damn hot about 20 years older than me (24M) her husband my uncle is in police , I get fucking scared Even though I think she likes me, When and how should I reciprocate her touches because my dad is unemployed, he stays at home , and my chacha is nearing his retirement. She touches me when alone , asks about my girlfriend.

One more piece of information, she allows me to touch her shoulder during conversation how should I increase my touches to touch her waist and boobs? I am a shy kid , with little courage but full of lust.

My uncle and aunt live on upper floor , I can on pretext use their bathroom and intentionally drop my towel for arousal, by making my dick hard and intentionally showing her this time

Even I have started touching her on arms,waist and shoulders, she is comfortable and doesn't show any signs of resistance

How should I proceed further???
