My Dear Uncle, I have been going through this mental dilemma for a few weeks now. I have been debating if I should confess to you or let it pass. But, I just can't carry this secret any longer as it is screwing up my piece of mind. It happened while you were out of town sometime last month. I got a call from aunty, your wife, asking me to come and help her with a project she was working on. She also wanted me to stay overnight so that she could get more time with me. It was all going great with the project work when she excused herself, went into the bedroom, and came back to join me in a transparent nightgown. I was shocked to see her almost naked. She sat beside me and started kissing me in my mouth. I pleaded with her to stop as it would be a betrayal and incest. However, she did not. But, I somehow pushed her off and ran out of the house. I never saw her or spoke to her again. Please manage the situation.
