I am a 18 year old boy, I live with my widowed mother, one weekend my friend stayed over, the first night we had both showered and changed into our pyjama's, mum called us downstairs saying tea was served on the coffee table in the lounge, mum was sitting opposite us in an armchair whilst we were on the sofa, then something embarrassing happened, my friend shuffled forward to reach his cup off the table and as he did so his cock and balls flopped out of the fly of his pj's right in full view of my mum, having his hands full with the cup he was unable to anything about it, to make it worse he was very well hung for a 18 year old, he was sitting squirming whilst mum thought it amusing, too make matters worse he started to get an erection, now mum was more interested as she said she has not seen such a lovely sight since my father had died, she said she didn't know boys could be so big, then she turned to me asking if I was as well endowed, I was surprised by the question, so I said the only way to find out is if I get mine out and compare, thankfully I was just as big as my friends, both of us with similar cocks of about 7 inches, now faced with two youthful cocks staring at her she said it was a long time since she had sex, so my friend quickly put his cup down and was kneeling in front of my mother lifting her up to remove her panties, she slid forward and her lovely hairy pussy was on view, now I had never seen her naked before, the occasion had got to her my friend pulled her onto his rampant cock and he was plunging it in and out of her, in her abandon she called me across to her, where she took my cock and put it into her mouth, what A great feeling that was for me as I was a virgin, soon my friend was spent and mum told me take his place I was going to fuck my own mum,I was soon fucking her fanny that was still full of my friends cum, after that week end I have had the luxury of being able to fuck my mum on loads of occassions
