All of my stories are true, with only names changed to protect the guilty.

I (M58) had just gotten a blowjob from Anne (85) my mother in law. It was her first blowjob that she had ever given. Hard to believe, but her and her deceased husband had been taught that oral sex was bad and dirty.

After taking her to a restaurant for dinner, I took her back to her apartment. I walked her in and she asked me to stay for a bit as her TV was not working. Well, it worked right away, so I realized that she probably wanted something else. She came and sat down on the couch beside me and started to rub my arm sensually again. We talked about her dinner for a few minutes and then she asked me if we could be happy again. I told her that it would be possible, but how asking if we could have sex again or if I could fuck her. She got really red in the face again and said that I was a naughty boy using that kind of language. I asked her some probing questions and found out that she had not had sex for at least 10 years before her husband had died. When they had sex she had never really cum. They did it in the dark, in missionary position, and once husband had cum, she got up and washed herself and went to sleep. She then told me that whatever I did to her made her feel so good. "Will you make an old lady like me feel good one more time" she asked.

I leaned in and started to kiss her. Kissing with tongue was also new to her, but she started to learn fast. At the same time I slid my hands up under her sweater and began to rub those saggy wrinkled boobs and felt those nipples instantly harden. Anne began to moan. I stopped, helped her up from couch and led her to her bedroom. She told me to turn out the lights, but I said that lights stayed on while I fucked her. As I kissed her and rubbed her tits, I began to undress her. While we had briefly fucked a couple of weeks ago, it was such a shock and a blur, I hadn't really focused on her naked body. Her boobs were definitely hanging and wrinkled, but a few licks with my tongue had those nipples fully erect. I helped her off with her skirt and she was wearing granny panties. I pushed her gently back on the bed and slowly slid those granny panties down. The panties were definitely wet in front already. Her legs were wrinkled all the way from her thighs down to her feet and she definitely looked old. The hair around her pussy was grey and getting sparse. I noticed that she had very big pussy lips sticking out. I parted her legs and began to kiss her from her thighs into the V of her legs. She was shaking all over and telling me that it felt so good, but I shouldn't do this as it was dirty. I told her to relax and just let me make her cum. With that my tongue found her clit and I was surprised to find that it was already erect and sticking out. Four or five licks and she shook all over and I felt liquid on my face. You are a dirty son she said, but don't stop.

Those pussy lips were so large that I was able to take them in between my lips and pull them up and suck on them. Oh my gawd oh my gawd Anne kept saying. From lips to clit and damn it all if she didn't cum again. I quickly shed my clothes and stroked my cock a few times to get it rock hard.

Do you want my cock I asked Anne. She just said that I was a dirty naughty son who was doing naughty things to his mother in law. I said that I was taking that as a yes. So I slid my cock into a tight, but very wet pussy. In between those big lips and past that sparse grey hair. You are so big she said. So big. It feels good. Make me happy she said. I pulled out and told her that she was to ask me to fuck her 85 year old pussy. I didn't think that she would use that language, but finally she did. In I went and began to stroke that pussy with short strokes and long strokes. Within less than a minute Anne started to shake, went red from her wrinkled face to her wrinkled boobs and then screamed out. She had fucking cum a third time in less than 20 minutes.

I asked her if she was able to move and get up on her hands and knees. She said yes, that is how she got up off the floor sometimes after her excercise. So I helped her do it on the bed and helped her get near to the edge of the bed. What are you doing she said. "I am going to fuck you doggy style", I told her. I can't do that she said. That is just too bad. People are not supposed to be happy that way. I told her to just relax, and if it was too uncomfortable that I would stop. I slid my cock in and just held it there about half way. Oh my, Oh my, Oh my she said. I then pushed all the way in so my groin was up against her wrinkled and flat ass. Normally I would have slapped her ass in this position but I held off as there was not that much fat on her old ass. I started to stroke in and out and she started crying out to keep going.

Anne totally surprised me next. Fuck me son, fuck me son she suddenly said. I picked up the pace, suddenly felt her pussy tighten, get really wet and she shuddered all over. That did it for me and I released my cum deep up into that 85 year old cunt.

She laid down on the bed and wanted to feel my cock. She examined it all over and kept saying how big it was. This is tiny compared to lots of cocks that I have seen I told her. (Her husband must have been very very tiny). I said that I had better be going and she said that she would talk to me tomorrow. I tucked her into bed noticing that she had not washed her pussy and still had a pussy full of cum. Let myself out.
