I woke up to My daughter (18) giving me head

First and fore most my daughter turned 18 in March. I (50m) have been a widowed Dad since 2016 when my wife was killed tragically. I guided my daughter through that, through her first period, middle school and high school.She is a 4'9", 120 lbs hour glass, with dark auburn hair and hazel eyes. She has been in dance since she was 6, so she has the build that comes with practicing hip hop and jazz dance 6 days a week for 12 years. We are close to say the least, we hang out all the time watch sci-fi and fantasy shit. I have never thought of her in any sexual way ever. My wife started a body safe practice in our house, if walked in on we didn't cover up this could imply shame at our nakedness. So we have all seen each other naked but not in a sexual way. I am saying all of this because I need help with what happened last night. I am sitting in my car out side my office typing this out.

Emily gets lonely in the night some nights and crawls in bed with me, this started just after her mom went into the hospital. This is normal, this happened last night. She usually sleeps on her mom's side of my king size bed, sometimes she wants to cuddle but usually she stays to her mom's side. I woke up last night to her deep throating my extremely hard penis and this is where I became a bad father, I didn't stop her. I let her give me the best blow job of my entire life. I pretended to still be a sleep, CPAP and all. When I came I came a lot and she swallowed it all and when I was done she kept sucking to make sure she got it all. She withdrew my penis out her mouth kissed the tip and tucked it back in my pjs. She then went to her mom's side of the bed and make herself cum three times, then crawl over and cuddle up with me, wrapping up in my arm. I could tell the masturbation by the vibration of the bed.
