Grandpa's Treat Part 2

After Mrs Duff and Mary left I sat back down and pondered about the situation, I couldn’t make Mrs Duff out, she looked good but business like and had quite a good body on her and the fact she took some cum from my shorts and licked her finger really had got me thinking, and what was all this about yogurt!!
I must have dozed off again because the doorbell woke me up, in a daze I walked to the door and standing there was Mrs Duff, “Hello again Frank, I just dropped a lad off up the road and thought I would pop back for a chat” she said as I invited her in.
Lots of thoughts were going through my mind, I was convinced she knew what had taken place. “Mary thinks very highly of you and was saying how nice you had been to her but I thought I would tell you about her” she said which surprised me and I was now thinking our secret was safe. “She had a tough upbringing, she never knew her dad and her mum is a bit of a slut, she has more ‘uncles’ than underwear” she said which hit me but then explained her experience. I didn’t know what to say really, “Oh really” is all I could muster. “Yes, she looks on you as a father figure” she continued. “She has never been a happy girl but I saw a change in her today” Mrs Duff said. I was somewhat surprised but good to have that information.
I made some coffee and we sat in the lounge. I still had the same shorts on and I saw her glance a few times and I still had an open shirt on. “You have a good body for your age Frank” she said looking me up and down, “Stand up, let me see you” she said her voice a bit stern, I wasn’t going to argue and as I stood up I felt in twinge in the nether regions, I stood up and she looked me up and down again and when she got just below the waist I knew it would happen, any guy will agree if someone is looking at your dick, it grows!!.
I was standing there and the bulge began to appear, “Oh my, Frank” she said, her voice softening, “What is happening here?” she asked, I muttered something as she put her hands in the waistband and slowly dropped my shorts to the floor, hence to say my cock sprung out and nearly knocked her glasses off. She slowly took the tip of my cock into her mouth slowly pushing it fully in, her tongue whipping round the head, withdrawing and then going again. I felt my knees shake as she cupped my balls, as she run her tongue up and down and all around my cock I heard her mutter, “Was Mary this good Frank?” I was so shocked that all I could stutter was “No” and then thinking that if she didn’t know what had happened then she did now. “You’ve not seen nothing yet” she said as she went to work on my cock, sucking up all the pre-cum. I held on to her ponytail as her head moved faster, she was really going for it. I was frantically trying to her shirt off and once I succeeded her bra came off quite easily.
I stood her up and her nicely rounded tits came into view, they were small and pert. We embraced into a passionate kiss, tongues exploring every bit of each other’s mouths and I reached round the back and unzipped her dress which subsequently fell to the floor which left her standing there in just her red lace panties. I bent her down over the sofa and slowly pulled down her panties exposing her cute arse and the sight of pubic hair between her legs excited me.
I bent down and kissed both cheeks followed by tongue running up and down her crack a couple of times while searching for her clit with my finger. She was already wet and my fingers slid into lady gate quite easily while my tongue found the back door. She relaxed and my tongue entered her arse as she moaned into the back of the sofa. As I finger fucked her she pushed her arse back on my face and when I stood up and positioned my cock at her pussy she pushed back in anticipation. I slid very easily into her wet hole, pushing in deep before withdrawing and pushing in again in a slow rhythmic motion, Mrs Duff was panting pulling at me to get in further, I was already up to my nuts and I am sure she has had bigger. I built up some speed and pounded away like two dogs before I felt Mrs Duff shaking with an almighty orgasm, I felt the liquid cover my cock and run down my leg and as I withdrew and offered it up to her arsehole my cum covered cock slid straight in there.
Mrs Duff was still shuddering from the orgasm as I pushed in deep, she responded by pushing back taking the whole length up her arse, I knew I was close when I felt my balls tighten and pulled out and shot my hot load all over her arse, “Mmm, that is so good” she said as the hot liquid hit her skin. I lent down and licked the sticky mess off her cheeks, taking great care to clean up along the crack, something that made Mrs Duff quiver.
I sat back in my chair, still naked while Mrs Duff got her breath back. She sat on the sofa and smiled, her clothes all around her. “Do we have to do an evaluation now?” I asked with a big grin, “Passed” she said smiling as we both laughed. “My husband would never fuck me up the arse” She said disappointingly, “And you do it so good Frank” I was pleased for the compliment.
We sat and chatted while Mrs Duff got herself dressed, she had to pick the other lad up soon, she told me that her husband was much older and the sex life had dwindled, I knew how she felt. She did look good, especially in her red lace panties which hugged her arse and her pubic hairs visible through the thin material. I had a feeling that I was going to be seeing more of Mrs Duff.
“I have to run now Frank, I have to pick Tristan up who is doing some gardening for Mrs Brown up the road” Mrs Duff said, “Gardening?” I said, “Can he come and do mine?” I inquired to which Mrs Duff said she would ask him.
We kissed by the door as Mrs Duff left knowing that she was going to bring Mary back tomorrow, it had been an eventful day. I walked back into the lounge and stood by the window looking at my overgrown garden, ah yes, I thought, Tristan would do a good job out there.
