I was visiting my daughter in law whilst my son was away on business,I had been doing odd jobs around the house for her, I decided to have a shower and get comfortable for the night, on going to get into my night-time attire I realised I had forgotten to pack my pajama's, shouting down to Sue my daughter in law she brought me a pair of my sons, I put them on and found they were slightly to big for me but I wore them any way, as we were settled for the evening we were watching a film on the television unknown to either of us there was quite an explicit sex scene, and being a man I started to get aroused and was horrified my cock was fully erect and slipped out of my pajama's I tried to cover myself but it was too late Sue had seen my cock, she said she was surprised at the length and thickness it was as my son's was not as big so she said, one thing led to another and soon we were petting, I soon lost all my inhibitions and was out of the pj's stripping Sue down to her bra and panties she put my turgid member into her mouth and sucking for all she was worth, I could not take much more I quickly pulled off her panties and had to enter her, I thought all my birthdays had come all at once how me made love all positions were tried, after our frantic love making we showered together then went to bed, we had three more days of sex before my son returned, on his arrival home he said been having fun! Little did he know.
