I am 43 and divorced and back living with my widowed Mother,last week about 2.0 am I was lying in bed stroking my cock,the light was on and I thought my Mother would be fast asleep,my door was slightly ajar and I saw my Mothers bedroom door open and heard her making her way to the toilet and shut the toilet door I dont know what came over me but I suddenly wanted my Mother to see my cock,I quickly opened my door a little wider so as she walked back it would make it impossible not to see in my room.Then lay on top of my bed with my stiff cock on show,as I heard the toilet flush and Mum unlock the door I began to slowly rub my cock,I heard her footsteps on the landing then they stopped I knew she was outside my door and could see exactly what I was doing,I shut my eyes and carried on rubbing it only took about a minute before thick blobs of spunk was landing on my stomach,as I lay there panting I heard her make her way to her bedroom and knew she had seen everything. I felt a bit ashamed but also very exciting and am waiting for a chance to repeat it.
