I've always wanted to fuck my mother-in-law. I mean my wife is really hot and her mother is fat and ugly; there's just something about her. It's probably the fact that she has massive tits. Yeah, I really like her tits.
My chance finally came, though I never thought anything would happen. She was to be alone for the weekend and had asked for someone to come over to help her. She's in her sixties and as I say kind of fat, so it didn't seem unreasonable that she would need some help. As no one else was available I offered to go.
I went over that morning and the day went fairly normally with the usual kind of chat. We had lunch and I didn't see why she would need any help at all.
Late in the afternoon she said she was going to have a shower.
After a few minutes she called out that she needed help. I wasn't too worried but I ran up the stairs. She told me to come into the bathroom. She was only wearing her underwear.
"Can you help with my bra?" she said. "I can't quite reach."
I expertly undid the catch with one hand and she slipped the bra off, revealing her enormous breasts. I could feel myself getting hard.
"You're going to have to take off my knickers for me," she added.
