Agnes, my Mothers friend

Agnes, my mothers friend, was having a hard time in her marriage and she was around at ours as my dad was out. She was having a drink and confiding her sorrows to my mother.
Agnes was very petite but well built, Babs Windsor type only she had dark hair. At that time she was in her forties. I always had a wee fancy for her as young boys often do. I had many a wank thinking about her. This night she got particualarly ***** and needed to go home. My mother asked me to walk her home and make sure she got in ok. Her hubby was working away from home at the time. Once I got her home and inside she said I just want to go to bed so I helped her into her room. I asked if she wanted a cup of tea or something and she said yes that would be good. I went off to make it. When I came back to her room she was out cold on the bed, blouse open revealing her bra and nice tits. One shoe on one off and her skirt up and tights pulled a little down as if she had tried to undress and fallen asleep doing so.
My heart was thumping at the sight and my cock was solid. I put the tea down and said your tea is here, no answer. I wlked over and touched her face to see if she wold wake up, no response. I said 'Agnes are you awake ?' a mumbled response, I said 'do you want to get into bed? a mumbled yes, I said 'let me help you undress?' I was waiting for a negative reaction, I got none. I took the bull by the horns and started to take her blouse off all the while waiting for her to say stop! She didnt so I continued. I took off her shoe and unzipped her skirt and slipped it down her legs and off. There she was lying in her white laced Bra, barely black tights and white laced panties. My cock was bursting against my trousers. I unzipped and let it out. Next I gently pulled her tights down her legs and and off, the feeling was unbelievable, so horny. Just her bra and panties now and me with my cock sticking out of my trousers. I was excited and terrified at the same time. I bent over her and lifted her back off the bed to unclip her bra, my hands were shaking. If she woke now she would see my exposed erection almost toching her chin as I held her in position and undid her bra.
My precum was actually dribbling on her cleavage as I lay her back down exposing her big full tits and dark nipples for the first time. No response or protest, eyes shut and breathing steadily she lay there quite still. I moved down the bed and started to pull her panties down. Her bare fanny was now there right in front of my eyes, a plump hairy mound. I slid her panties all theway down and off. The excitement I felt was now ruling my brain. I got off the bed and and touched her tits, gently rubbing her nipples, which to my surprise hardened at my touch. I was now wanking and touching her. I moved back to the bottom of the bed, all fear gone, my cock was in charge now. I knelt between her feet and opened her legs completely, exposing and opening her fanny. I could actualy see it open further after I stopped moving her legs open. I thought that is where her hubbies cock goes, where he shoots his spunk up her. I was now ready to explode, I moved my cock closer to her fanny and touched it with my wet swollen cock. I was so tempted to go all the way, but reason got hold and I reached for her panties as I wanked over her open fanny, I came in her still warm panties, the feeling was so good.
I slowly got off the bed wiped my cock clean with her panties, left them on the floor, pulled a cover over her and left.
I was terrified the next day waiting for my mother to say what did you do last night, I was sure Agnes would see the mess on her panties and tell my mother. She didnt, nothing happened. I was quite sheepish the next time I saw her but nothing was mentioned. Did she know what I was doing, did she lie there enjoying it or was she actually out of it. I dont know but it was an amzing horny erotic experience which I will keep forever and I still wank thinking about it to this day.
