Older Pussy Always There

On a lark I used a dating app to look for older women one day, and found a woman in her 50's who lived just a couple blocks away. Marsha is heavy set and short, with a cute face, and some kind of retardation so she doesn't think very clearly and doesn't seem more sophisticated than a 20 year old. She lives with one of her two daughters, who also has a young son. She can't drive and doesn't get out of her apartment much so she was a bit lonely, and invited me over during the middle of the day. She was wearing only a thin nightgown which let me see her tits pretty easily, and soon she let me suck and nuzzle my face into them. She offered a blowjob, but I soon found she wasn't very good at it, and could never bring me even close to coming, and for that matter she said she never swallowed anyway. I came on her face once but she found it disgusting. But eventually we tried fucking and I found that her vagina was always well lubricated so it was easy to fuck her on the edge of the couch. I never last long this way unless I try very hard to hold still and think about something else; usually I am ejaculating inside of her in less than five minutes. Once I did that and then ate her out for about an hour, then got back inside and lasted quite a bit longer, which was more enjoyable.

I know I should look for a woman my age who I could date seriously, but it is a constant temptation to go for this always-available pussy. I wonder sometimes if her daughter or grandson might come home in the middle of the day and catch us mid-fuck, but so far that hasn't happened.
