I took advantage of my mom when she was drunk, felt great at the time but later on I felt really guilty. The thing is she never acted or treated me like she realized anything happened, I did not have intercourse with her though just a lot of touching and oral.
I was so worried she was going to be just livid with me the next day but when she came out of her bedroom she was completely normal, except for a big hangover. She told me a few times that she barely remembers going over to her friends house for the party, even laughed thinking maybe she did some drugs or something because she felt like she lost a whole day.
I told her she did seem pretty drunk but came home and went to bed which is pretty much what happened with me groping and helping her along the way then stripping her naked and having fun. I still feel really guilty about it twenty some years later.
