-----------------------------
The story begins many years ago after my mother passed away. I was 14 at the time with 3 younger brothers and a now widowed father. About a year after mom passed dad met a much younger woman, and I mean much younger. Sheila was half his age, 18 to his 38, only God can explain such attractions, I like to say it's just proof God has a sense of humor. And ya, dad was a bit of a horndog. At the time she was an ardent atheist but that eventually changed, more on that later.
I was too immature to understand it all and didn't have much of an opinion of her at first. She was just a new face that dad said was going to be around a lot. Out of respect for mom, Sheila never encouraged us to call her mom, she was just Sheila. She was extremely smart, having graduated high school a couple years early and had just entered university, only 4 years older than I was. More than once relationships had to be explained after quizzical looks.
Now, about Sheila, she was/is a braniac nerd and I mean that in every possible definition. Very very intelligent, bordering on savant, graduated high school 2 years early, at the top of her university class but she could and can be shockingly naive. She was a book learner with near zero practical life experience thrust into being the mother of 4. That had to be difficult and likely further limited her worldliness.
Well any way, Sheila neither is nor was a shocking beauty, very plain and ordinary looking. She has a body you might check out while waiting in the super market check out line but that's likely about it. She stands 5 ft 7 in, shoulder length dirty blonde hair bordering on an auburn which she kept cut short and permed in curls. She wears contacts most of the time, and was never over weight, watching her figure closely by doing yoga and all the fashionable exercise programs. I'm guessing about 130 lbs and a respectable 33-26-34. Quite shapely but a very flat ass. She dresses very conservatively meaning no low cut anything, always knee length or longer for dresses, occasionally a pants suit. She hates popular music, listening instead to 60s crooners and musicals.
About 4 years after they got married there was a dramatic change. Sheila became a hard core born again Christian. Her faith is deep, literal, and unshakable... or so it seemed. For the remaining time I had living with them life changed accordingly. Church every Sunday, youth groups, church trips, etc...
Sheila was simply Sheila to me. I found an interest in women rather late. Only then did I begin to see her as other than a step-mother as puberty and testosterone flowed. This led to me spying on her a few times. Our house was built in the 20s and had a really weird layout. Suffice to say that this layout of rooms and windows offered peeping opportunities. Several times I watched her in the bathroom and she'd strip for a bath. We didn't have a shower at the time. The first time in saw her in all her naked glory sticks in my mind today. Blouse then skirt followed by bra then nylons then panties. it was the first time witnessing a woman take down her bra straps and then twisting the bra around so she could unclasp it under her tits. Her tits were nice, firm, with quarter inch nipples, her dark pink areola puckered in the cold and her nipples grew. She stood both hands up ruffling her hair for a moment (God did that ever lift and accentuate her tits) before letting her right hand descend into her thick wild pubic hair and idly scratch a bit. Then she got to with in inches of me as the tub was under the window. A brief flash of pussy as she stepped in and I had to retreat to stay covert as it were.
I failed.
The next morning my dad and Sheila sat me down at the dining room table and didn't outright accuse me of spying but said she'd heard a noise outside the bathroom window. They went on about how young men get curious about women, etc. I denied it of course.
It did teach me caution because I didn't stop.
Another moment comes to mind. I watched her masterbate under the covers yet didn't realize what I'd witnessed until much later. Along the head of their bed the wall had 2 windows, one on each side. The bed centered between them. The windows were always open about 6 inches in order to allow the swamp cooler to work. So I was outside the window just over her right shoulder. Sheila was laying in bed reading a book, the bed covers just below her bare tits. I never paid attention to what she was reading but was focused on her left hand because it was cupping her left breast and her thumb and forefinger were tweaking the nipple, a very erect hard nipple. Soon that hand slipped under the covers and moved to her crotch, the covers began moving up and down. Over the next few minutes her areola puckered as the covers moved up and down faster. Her breathing was deeper raising her tits up and down. Then without a sound, the covers stopped moving and she jerked a bit, I suppose I would say she panted just a few times. In retrospect it was kinda funny she never stopped reading the book but, then just like that, she turned off the light.
Dad and Sheila were certainly sexually active. The only time I ever "caught" dad and Sheila in the act was after I'd left home but was back for a short visit. I'd crashed on the couch next to their room and was wakened by Sheila's voice, "yes, there" "oh that feels so good" etc. She was either getting fucked good or dad was chowing down, anyway obviously they were getting busy.
Moving this along a bit... I've never had a conversation with my brothers about what they thought of her. I do wonder if they did their own peeping but I suppose it doesn't really matter anymore, just titillating.
My dad wound up passing away away relatively young. He was 68 meaning Sheila was 48. 4 years later Sheila met Ron.
The situation surrounding Sheila and Ron becoming a couple was eye opening. I'd always thought Sheila was a deeply moral religious woman. Yet she sat my wife and I down and announced she was "the other woman" in Ron's life. We were beyond shocked. So here's a woman with deep faith schtooping a married man... and she was fine with it. Well, this brought her moral flexibility into sharp focus, so much so that one of my brothers cut her off. The more I thought about her actions over the years the more I saw hypocrisy. She still is a woman of deep faith, but that faith doesn't extend to aspects of her personal (read that as intimate) life.
Ron was no replacement for Dad but he was a great guy. Sadly he was 16 years older than Sheila and he passed away 4 years after their marriage. Now Sheila was twice widowed at 56. She's made it clear she wouldn't get married again. I teased her about being a voracious cougar and thought it quite witty until I had to explain what a "cougar" was.
My situation briefly. Happily married to a wonderful mother and companion who, due to several medical conditions which has arisen since Covid and the vaccines, should not have vaginal sex. She is very conservative and frigid when it comes to sex and has always been a no foreplay woman, read that as zero foreplay. Not for lack of me trying to be the attentive sexual partner. Essentially a very repressed attitude toward sex. Meaning no oral, little groping, sex occasionally. Her libido is now zero, sex is painful. Why did I stay with her? Because I love her.
Me? I suppose you could call me sexually inexperienced, our sex life is very limited. Two or three times a year, no penetration due to her condition, rubbing or a hand job to my orgasm. Believe me, I want a lot more and can certainly perform but the circumstances you see... nuff said about that.
Several months ago a nasty thought wormed its way into my mind. Here's Sheila, who I know enjoyed her sex life, at least with dad anyway, now without a partner at the same time my partner has become unavailable. So for several weeks my mind was calculating and weighing pros and cons, what reaction would I get to an indecent proposal, the right way to broach the subject, and how I'd proceed if she agreed. I was relying on Sheila's very flexible morals being able to bend to the near breaking point.
Without much thought I began laying the ground work. Complimenting her when she picked up my wife to go walking, hugging her a little longer each time she went home, making sure I paid a bit more attention to her than I used to. There was even one golden opportunity which gave us all a good laugh and planted an unintended seed.
They were sitting in the dining room drinking their post walk tea and chatting. I was in the den half eaves dropping and half watching Youtube. Some how they'd gotten on the subject of how my wife and I decided we'd each found our soulmate.
Sheila called to me, "So what about Denise made you love her so quickly?"
"Well, I had to find someone as beautiful as you. When I did, I wasn't letting go."
I have no idea their reaction since I was facing away in a different room but they didn't ask more.
Later I got up to go to the bathroom and was just walking behind Sheila's chair when I heard Sheila say something about her being frumpy and old. My wife shushed the idea. Much to my own shock, just as I rounded the corner out of their sight, I blurted out, "Oh hell you're still a desirable woman, I'd do ya." There was a moment of silence and then a burst of laughter. When I returned I leaned over the back and kissed Sheila on the cheek saying, "Sorry about that, I couldn't help myself."
She swatted at me as I walked away.
Denise was unusually quiet the rest on the day. I asked her about it but she said she didnt feel good.
Later that evening we were laying in bed doing our nightly ritual. Denise was playing a game on her phone and I was watching Youtube on a tablet.
Out of the blue I hear, "Do you think you would?"
Not really paying attention I replied, "Would what?"
"Do her?"
I looked at her, "What do you mean 'do her'?"
"Would you do Sheila?" she said.
"Huh?"
