This odd conversation in an 'emergency' situation seemed to give me permission to masturbate.
This happened when I was at university and my Mum was driving me home at the end of term. It was quite a long journey and we had been going for a couple of hours when we got stuck in a massive motorway hold-up. After some time at a standstill, my Mum said that she badly needed a wee.I had realised she was fidgeting a bit and this was obviously why. I was wanting to go quite urgently myself and had been trying not to show it.
We were just stuck, going nowhere with no way we could get out of the car and go decently. After a bit, I was getting more desperate and I could tell my Mum was in difficulty too. I noticed that she had her hand between her legs and was discretely rubbing herself, obviously in an attempt to hold it. She saw that I had seen this and said that she was sorry but she really was bursting. Then the surprising bit came.
She said that it must look like she was playing with herself but she was really desperate. Then, to my surprise and, I suppose, shock, she said "I do sometimes play with myself. Don't you? I bet you do. All girls must do it sometimes". She went on to say that it was usually when my Dad was away that she did it and added that needing to wee sometimes made her want to do it though it was a long time since she had been as desperate as this.
By this time I was bursting too and was not sure that I could hold it much longer. Mum said that if we didn't get moving pretty quickly and get to a motorway services there would be a wet seat.By now I was openly holding myself too and gently rubbing myself.
I was amazed at this turn in the conversation. I would never have guessed that I would hear this from my Mum but, looking back, it has somehow seemed to put a seal of approval on my own masturbation.
