many, many years ago (1979) I did something similar with a friend that was passed out on the couch after we had a night of drinking. Unfortunately, or fortunately, I was unable to stop and ended up cumming all over her Hair, especially her bangs. Not knowing what to do I just went to sleep. Wen I woke up in the morning she was already up and she asked me if I knew what happen to her Hair. Since there were other people who stayed over that night I just played dumb and said nothing. We stayed friends for a number of years but we never talked about it. To this dy I wonder if she had any idea what happen.
