This wasn't really starting on purpose. Basically since I was a little kid l'd go back to my home Mom's country for vacations as a kid. I would stay at my aunts place and our relationship was strictly aunt/nephew. Ever since I was a kid, she would always help me bathe, like any aunt would do. And I innocently said okay. And to be fair it was innocent, I was a little kid. I was naked and she was clothed.

Flash forward to now, at 19, I go back to visit and my aunt asked to me to take a shower. I said okay, and jokingly asked if she could help me. She said yes and I agreed. I went into the shower in my underwear and she agreed. She then asked why I was wearing underwear, and I said she was wearing her clothes too, and that I was more naked than she was.

She said nobody showers in their underwear, and I said, if I gotta be naked so do you. I said it jokingly, but she was serious. She took her top off, and suddenly, I was really aroused. I've never had these feelings for a family member before, but nonetheless, I got fully naked too. She then took her shorts and panties off and was standing there fully naked. She had a really nice shaved pussy that made my dick hard uncontrollably. She claimed that it was gross and asked me to stop doing that, but there was a nice naked woman in front of me, and I couldn't control it.

She starts rubbing my back with soap and squats down to my legs. She then gets back up and asks me to turn around. I turn around and for whatever reason I kiss her on the neck, then on the lips and we make out for a good couple minutes. I then stop and we agreed to never talk about this again.

But then the following day she said we should shower together to save some water. This time we kissed again, but nothing overtly sexual and I really liked it. What should I do?

EDIT: I would like to add that I’m not interested in sex, I just love seeing her naked and kissing her and am attracted to her body. I know sex would be the next option, but it still feels weird. Any suggestions?
