I decided not to ask. Instead, I said, “I didn’t know we were keeping score.”She smiled and pulled my face to hers. I extended up for the kiss, ...nd she moaned from the additional pressure I applied between her legs.She pushed on my chest and I stood up. She dropped her feet to the floor and sat up. With me standing at the edge of the bed, she reached up and rubbed on my chest, but she didn’t stay there for long. Her fingers ran down me, her touch feather light. She reached the waistband of my. I asked how her night had gone and she said fine, and Jo seemed to be loosening up a bit about being around me. She confided that she was kind of flattered about my saying she had a great ass, and asked if we did that sort of 'what should I wear' thing all the time. She'd also had noticed that I'd check out her chest while I was getting dressed and wondered about that, as I hadn't checked her out and she had been stark naked, so they'd talked a while about that and Kathy got around to asking. It’s a cruel twist of fate when a couple work all their lives toward their goal of retiring and traveling together and then something like a heart attack in the middle of the night a year after retirement dashes the dreams to pieces. Mom had been alone for nine years now.We talk several times a week and I try to visit at least once a week, but the past two weeks had been so busy that I’d missed lunch with her last Sunday. When she saw me at the door she looked quizzically at me and asked. She immediately got her knees under her, raising her ass up and pointing it at me. I knelt behind her and pulled her thong down over her ass to her knees. Her bare pussy lips were pink and swollen and glistening with her juices. "Yeah that's it," she taunted, "lookit that pussy, all wet so you can fuck it, you fucking pervert. Fuck your little sister, shove that cock right in there and fuck me, take me hard, you know you fucking want to so fucking do it!" If you insist." I aimed my cock at her.
