Since my marriage broke down 2 years ago,I have moved back to my mother's house,she is 62 and a widow.She never really liked my ex wife and when she found out that Ann my ex had cheated on me,she didn't try to hide her feelings and told me she thought it was only a matter of time. Anyway about 2 months after moving back we were sitting watching a program about cheating husbands and wives and she asked me how I had found out about Ann and how I had felt,I reluctantly told her that I caught her naked in our bed with a man we had known for years,she then asked how I had felt seeing her with another man,when I told her I felt sick in my stomach but also strangely aroused,she immediately said "I knew it,you are just the same as your father,he was into other men going with me" "and did you??" I asked nervously,as my cock began to stiffen with the conversation.Mum lowered her head and with a look of embarrassment,nodded "yes on numerous occasions,right up until your father's sudden death," "and did you enjoy it??"I asked getting more excited by the minute,"of course I enjoyed it,I have always enjoyed sex and miss it so much"and with that she rose from her chair and said "I'm going to bed" As I sat there alone going over mum's confession and imagining her and my dad in a threesome I felt my cock once again getting hard and decided to turn in and have a wank in my room,as I passed mum's bedroom I heard muffled sighs and thought she was crying I opened her door ready to comfort her,but what I saw was mum her knees bent and nightdress around her waist pussy exposed and her fingers rubbing her swollen lips I quickly said sorry but not before feasting my eyes on her open c**t.she made no move to cover herself she did in fact open her legs wider,which was too much for me,I began throwing my clothes to the floor,not taking my eyes off her pussy and then I was on the bed with her pulling her nightdress over her head so we were both naked then for the first time in my life I entered my mum,as my cock slid into her it felt so natural and as our lips met and our thrusting became more urgent I heard mum say the magic words "fuck me Tony" and my sperm shot deep inside of her.As we lay in each others arms mum was the first to speak "that was beautiful I needed that so much" "me too "I replied then we drifted into a satisfied sleep. When I woke in the morning the realization hit me,I had fucked my own mother but before any feelings of guilt could overwhelm me,mum stirred and before I knew it I was once again buried deep inside of her filling her with my hot sperm.Since that night we are to the outside world mother and son but indoors we are lovers and long may it last.
