Sometime after my sister-in-law Jane's husband finally returned from duty in Afghanistan and they went back to live at theirs (see "Servicing My Sister-In-Law" published here on 22 Jan 15), my wife Alice's widowed 49 year old mother Sarah came for an extended visit. Sarah and I have had a warm and easy relationship since the first time Alice brought me home to meet her folks. Over the intervening years, and especially since Alice's dad died few years back, the relationships between Alice and her mother, and her mother and me, have become even closer and more comfortable. Sarah lives just three hours away by car so we see quite a lot of her, usually at ours now that she no longer works and has the free time to stay with us for several days. Alice particularly likes this since she and her mother can have lots of 'girl time' while I'm at work. Then during the weekend we do things as a threesome. A few times we have tried to set Sarah up with eligible men we know to go out on a date with us, but without any success. A few weeks ago, Sarah arrived on a Wednesday for a week's stay and she and Alice had 'girl time' until the weekend. That Saturday morning Alice left early to do a few errands while Sarah slept in and I did some work on the computer in my comfortable office/reading room located next to Sarah's bedroom. After a while I heard Sarah get up and pass by my open door on her way to the loo. On her way back, she leaned in the doorway and asked if she could visit while I worked. I told her it was more than OK and invited her in. Still dressed in her housecoat over whatever she sleeps in, she sat in the easy chair opposite and looked around the room for a few minutes while I finished up. I then sat back in my desk chair and we started to talk as we always do. We talked of inconsequential things for a while until she asked why Alice and I had tried to get her to date men. I asked why she was talking to me about it instead of Alice. She said she had talked to Alice about it and got the usual reasons such as loneliness, male companionship, etc., but wanted to know why I was in favor of our efforts. I told her pretty much the same things as Alice plus that we were concerned for her well being. She then shocked me by saying she had a very happy life and only missed the sex. My mouth fell open in surprise and I stammered for a few seconds as my mind wrapped around this revelation. Finally, I asked her why she wouldn't go out with the men we suggested to her in the past if she wanted sex. She told me she didn't want a relationship, just the sex, but was embarrassed to go on a date, or the pull, to have sex with a strange man. She said that sex with Alice's dad was so good because they knew each other so well and their relationship was so warm and comfortable, and she couldn't imagine having sex with any man she knew for only a short time. So I asked her how she thought she was going to have sex if she didn't date men. Her answer shocked me. She said that, since she felt so close to me these many years and, over the years, had fallen a bit in love with me, especially after Alice's dad died, I was the logical one to provide what she needed. I just sat back in my chair dumbfounded. She gave me some moments to let that thought sink in, then stood up and slowly opened her housecoat and lowered it to the floor. She was wearing a short almost transparent nightgown that showed off the same taut slim figure as Alice. I could see through the nightgown and saw her firm medium size breasts with their dark nipples and the light brown hair covering her feminine mound. From the standpoint of feminine physical attributes, she and Alice could have been sisters. After giving me a few seconds to take in her womanly charms while she gazed at me with longing in her eyes, she then slowly moved the short distance to where I was sitting and quickly lowered herself onto my lap. I was too shocked to stop her. As she sat on me I felt her gently wiggle her bum against my groin. When I told her she should get up, she just smiled and put one arm around the back of my neck and ran the fingers of her other hand through my hair as she lowered her mouth to mine and gave me a few short kisses. It was obvious that Sarah, just like her daughters Alice and Jane, was an uninhibited and experienced lover. I pulled my head back from her face and told her we shouldn't be doing this, to which she replied "Alice will be out for at least an hour or more doing her errands. Come with me to my room and make love to me. I've know for many years you care very much about me as a person, so this will be just the next step in our relationship. I really need this and just can't stand the idea of going to a strange man for it. I don't have any desire to establish a relationship with someone I don't know just to have sex. You're the ideal solution." I told her I couldn't betray Alice this way and asked if she had talked to Alice about it. She replied "I'm too embarrassed to go to Alice with this and take the risk my request would harm my close relationship with her." I replied "Don't you think Alice finding out about us could harm your relationship?" But she said "Alice won't find out. I've got it all worked out how we can meet in the future." And then she lowered her mouth to mine again and kissed me urgently, running her tongue over my closed lips until I opened them slightly, and she darted her tongue inside. I couldn't help but return her sensual kisses and then wrapped my arms around her pulling her tightly into me. The movements of her bum against my groin and our wet erotic kisses very soon had the desired effect. My cock rose up fully erect. When she felt it push up against her bum she moaned and wiggled her chest against mine so I could feel her firm breasts. I then felt her hand pull mine onto those luscious breasts, and I was lost. I kneaded her breasts and rolled her already hard nipples between my fingers, which elicited soft mewing sounds from her. After enjoying my attention to her breasts for a while an with a smile on her face, she got up, grasped both my hands, and pulled me up. Lust had now seized me. She moved into me and gave me a full body hug, grinding her groin into mine, and reached up to pull my head down to hers. We locked our mouths in another deep French kiss as I reached behind her and ran my hands down over her bum kneading her cheeks and pulling her tightly into me. We kissed and caressed like that for a minute or two building up our passion when she said "Let's go to my room. I need you in me now!" and pulled me by the arm. We quickly stumbled into her room, shut the door, and undressed. Since she had on only a nightgown, she was naked and on the bed by the time I got rid of my clothes, finally releasing my cock which sprang up full length. She was watching me intently as I approached the bed. I crawled up onto the bed, then sat back on my haunches and I stared at the sight before me. She was on her back, knees raised and legs parted wide, slowly fingering her slit and gazing hungrily at my cock. I stared at her fingering herself for a few moments, then saw her roll her hips upward against her fingers which were now deep within her cavern. She was staring hard into my eyes, mewing softly but urgently, asking for relief. I snapped out of my reverie, moved between her legs, and lowered myself onto her. Her hand quickly moved down between us and guided my cock to her entrance and guided the tip in as I pushed forward a bit. I then thrust a bit into her, moved out and, as I could feel she was very wet, thrust all the way up her in one smooth movement. I paused to let her get used to me, but she was too far gone with need. She immediately bucked her hips up into me, pulled me tightly into her with the arms and legs she now had wrapped around me, and said "Do me now. It's been so long. I need you to make me come now! Just fuck me, fuck me hard!!" I quickly established my rhythm and plunged deeply up her over and over again. Her passion rose quickly and she thrust her hips back against me, grunting in time with my strokes. Her internal muscles nipped at my cock and I could feel her body rising toward her climax. My need was also quickly rising along with hers. I soon went into overdrive and pounded her hard and deep. This was what she wanted - what she needed after several years without a man, and she soon was loudly moaning and gasping, her body writhing under me. By now I was consumed with lust for her and could feel my climax rising swiftly to completion. I pounded her as hard and deep as I could, then felt myself go over the edge, grunting out my orgasm with repeated cries of "I'm coming! I'm coming!' as I sprayed my cum deeply into her, my hips jerking uncontrollably. During my climax I felt and heard her reach hers. She screamed out her climax as she rammed her hips repeatedly up into mine for almost a minute as the waves of her orgasm rolled over her, then her body went limp. When I was finished, I collapsed on her, buried my face in the crook of her neck and kissed her repeatedly. When she finally could speak coherently, she whispered into my ear "God, I needed that! You can't imagine how much I needed that!" We cuddled on our sides facing each other, running our hands over each other's back and bum, and repeatedly kissing and hugging. After a few minutes, she pulled her head back and asked me "Was it alright for you? You were fabulous for me, but I want to make sure I was alright for you. Was it OK for you?" I looked at her with surprise and replied as I chuckled "Couldn't you tell? I practically raped you I was so horny for you! So, yes, you were fabulous for me, as good as Alice, and she's the best! I guess it's 'like daughter, like mother." She shyly smiled and thanked me for the compliments. After a few seconds she continued "I want you again, but we need to straighten up before Alice returns." I agreed with her. We cleaned ourselves up, got dressed, and returned to my den where we sat and discussed what had just occurred until Alice returned home. What we discussed and what subsequently happened will have to wait for next time.
