Sissy humiliated by mother in law

This is a true story, at the time I was on holiday with my wife (Susan) and my in laws were with us and sharing their holiday house. I always sleep naked, and Susan insists and my genitals always smooth and shaved. I had got up to go to the loo yesterday morning. However I was in there sometime and hadn't realised that Susan had got up and was sitting chatting with her mother on the patio outside our bedroom. So I walked back into the room naked and in full view of Susan and her mother. I jumped aside but obviously by now my mother in law had seen the full picture, I got on a pair of shorts went to go to the kitchen and prepare breakfast. However as I left the room I heard my mother in law saying 'that's a first for me'. Intrigued I waited out of sight to hear what they were chatting about. Susan said 'what?' To which her mother replied 'seeing a man shaved down there'. Susan replied 'I like it that way' to which her mother (who is 72 years old) replied 'I'm not surprised it must help you to find it!' Susan just said 'Mother',sternly but jokingly, and they both began laughing long and hard. I was so embarrassed that even my mother in law was joking about my tiny shaved thingy. I was so humiliated and loved it if only she would tease me openly about it I would gladly serve her and Susan. My mother in law is on her second marriage and her husband is very much a mans man, he always tuts and mutters his discontent when he sees me cleaning up, doing dishes or hanging out the washing, you know all a sissy's chores. I can imagine he would have some very harsh words if he knew I wanted to be a cock worshipping sissy, cucked by his step daughter and wife. It still gets me so humiliated writing this now thinking of my mother in law giggling like a school girl about my tiny member.
