The most taboo thing I have ever done was play around with my mom. She was a pretty big party girl in her forties, my parents had divorced when I was around ten and four to five years later she was going out and having a lot of fun coming home just plastered sometimes.
She told me more than once she could not even remember coming home. I was helping her one night when she fell down right in the entryway taking her shoes off I think, I got to her and she was laughing and I could see right up her skirt to her underwear.
When I got her up to her feet she was leaning on me a lot, had an arm over my shoulders and the side of my face was against her shirt. She was so uncoordinated I knew she would not remember anything and started undressing her. She sat there staring at me and said Okay! Strip me baby!
Once I had her clothes all off I just started running my fingers all over her breasts, nipples and downward, she just laid there with her legs spread out giggling and moaning. She reached down at one point, spread her lips apart at the top showing me her clit and told me that was what I should be play with the most.
I played around with her probably a dozen times or so in my teens, never said anything about it the next day.
