"Eric, I have to tell you something," mom said.
"What?"
"I... uhm... that is... I..." she stammered.
I looked down at her. "What is it mom?"
"I... kinda... told your Aunt Sabrina about us."
"What?" I asked, "You told Aunt Sabrina? What happened to 'We can't tell anybody about this'?"
"I know, I know," she said, looking up at me apologetically. "I didn't mean to, it was an accident."
"How do you accidentally tell your sister that you're fucking your son?" I asked, a little confused.
"Well it all started when I stopped by her place a couple of days ago. You know we try to get together a couple times a month to catch up. But since she lives halfway across the city and with me running the bakery, it's not always easy or convenient. Anyway, I stopped by for a visit a couple of days ago, and we got to talking about relationships."
I knew all about Aunt Sabrina's last relationship. She met a guy named Earl that seemed to be perfect. And that was the problem, he was too good to be true. He turned out to be a con man named Lonnie, who ripped my aunt off for nearly five grand before she finally caught on. She wasn't his only victim, but she was his last. Her police report, along with all the others, was enough for the police to finally track him down and arrest him (Earl was one of at least seven aliases he used to scam women). That happened around the same time I lost my job. Since then she hadn't bothered trying to even so much as dip her toe back into the dating pool.
Prior to that she had met a guy (Henry) that cheated on her. So despite her being the one that pushed mom to start dating after the divorce, she wasn't very trusting towards anyone with a penis.
So this is basically what mom told me.
For the last three months mom simply didn't mention our new relationship to Aunt Sabrina who was still bitter over her relationship with Earl/Lonnie and was venting to mom about it.
"My dating life sucks sis," Aunt Sabrina said to mom. "I mean there was Henry, and then Earl or Lonnie or whatever the fuck his name was. Are there any decent men left? I just want to find a decent, caring man."
"I have." mom said, realizing a second after the words were out of her mouth that she fucked up.
"You have? Why am I just hearing about this now? And when did you start dating again? I thought it was just you and Eric... oh my god... Susan, you're not..." Aunt Sabrina stammered while staring wide eyed at my mother. "How could you? He's your son for fucks sake!"
Aunt Sabrina could read mom like a book (they were sisters after all) and she could tell by the look on mom's face that what she suspected was true.
"It's not like I planned it... at least not at first. I came home and caught him masturbating, and well, you know it's been a while since... oh what was his name?" mom racked her brain for the name of the last guy she'd slept with. "Chris? Carl? Charles? I can't remember, I know it began with a C, anyway, it's been a while since I've been with a man, and you know how much I love sex."
"That's an understatement," Aunt Sabrina said, "You'd fuck anything with two legs and dick, but your son?"
"Will you let me finish?" mom said, "It's been a while since I'd seen a flesh and blood dick. Up until now I've had to use my toys to get myself off, but when I saw Eric's cock, even if it was just for a second, it got me excited. He avoided me until dinner was ready and I asked him if he was still embarrassed about getting caught, and made an offhand comment about how he'd 'grown up'. I apologized for it later, saying I thought he didn't need me anymore, but he assured me he does. But he felt he was being a burden to me, and I assured him that he wasn't. That night before I went to bed, the image of him stroking his cock jumped back into my head and I got excited. I pulled out that nightgown that I bought for my honeymoon with fuckface, and decided to see if it still fit. It did, so I wanted to see if I still had what it took to get a man excited. I kept it on when I said goodnight to Eric, and it was blatantly obvious that he was staring at the girls. He definitely liked what he saw."
"Well you did inherit the big tit gene from mom," Aunt Sabrina said, looking down at her 36B's.
"Anyway, when I saw his reaction, I knew I still had it, and before I went to bed I masturbated to one of the most intense orgasms I've ever had."
"TMI, sis." Aunt Sabrina said, smirking.
"You asked," mom said, "Now, I admit I felt guilty afterwards, but at the same time, there was a part of me that didn't. That part won out, so I formulated a plan to get him to fuck me. The next night when he came home I asked him to sit with me, and eventually got him to lay his head on my lap. I remember when he was little it would always make him sleepy, so I wanted to see if it still worked. It did, and as he slept he rolled onto his back and it was obvious he was hard. So I agreed with the little devil on my shoulder, and pulled his shorts down so I could see his cock. I wanted to touch it, but I thought I shouldn't, like you said, I'm his mother. But that's the thing, I AM his mother and my job is to take care of his needs. All of his needs. So I started stroking his cock, and of course that woke him up. Once he realized what was going on I convinced him to just enjoy it. I let him suck on my tits, and eventually I made him cum."
Mom had admitted to me that getting me to sit with her and lay my head on her lap was mostly planned out. She had a backup plan (she never told me what it was) if that didn't work.
Aunt Sabrina was squirming in her seat, and so was mom. As she recounted the story of how we both masturbated each other to orgasm and then fucked on the couch, they were both getting more and more turned on. While mom was remembering the events of that night, Aunt Sabrina was trying to visualize it.
"And my boy can fuck!" Mom said, "I hadn't been fucked that good in a long time. It's like his cock was made for my pussy. I can't get enough of him, we've been fucking every day for the past three months. I know what we're doing is wrong, but --"
"If you say 'how can something so wrong feel so right?' I'll kill you." Aunt Sabrina said.
"I was actually going to say I don't care." Mom said, "I love that boy more than anything else in the world, you know that. That's why I fought so hard for sole custody of him in the divorce, ever since he was born my world has revolved around him. I would do anything for him. Including letting him fuck me. It goes both ways, if he wants to fuck, I'll happily take his cock, and if I want him, he gives his mommy what she needs. I've fucked a lot of guys, but he's the most considerate lover I've ever had. We share a bond that only a mother and son can. I only wish I had realized it sooner. I don't care what anyone says, I love fucking my son. And I'm not going to stop."
Aunt Sabrina went from being appalled to aroused. Listening to my mother talk about our sex life was turning her on. It was getting to mom too. She was having trouble controlling herself as well. Both of them were squirming uncontrollably now.
"How... how big is he?" Aunt Sabrina asked.
"You know, we never thought of measuring." Mom said, "But if I had to guess, maybe 8, 8 1/2 inches. And it's thick too. All I know is he fills me up every time. I've sucked his cock so many times, I've had him in my cunt, in my ass, I even let him tit fuck me. We've done just about everything. We've tried all sorts of positions. And his stamina! I can usually get him off twice, and we can go for well over an hour if we pace ourselves."
At this point Aunt Sabrina had slid her hand inside her pants and was rubbing her clit, and wasn't even trying to hide it. Mom's pussy was also wet, and she unfastened her jeans and started masturbating as well.
"Does he... can he eat pussy?" Aunt Sabrina asked, and noticed that mom had started masturbating as well. She pushed her pants and panties down and was now openly masturbating in front of my mother. "Does he tease your pussy with his tongue? Does he nibble on your clit?"
"Oh my baby boy eats pussy like a fucking pro!" Mom said pulling her pants down as well.
It was at this point I was hard again and rolled mom over and started fucking her. She moaned in pleasure but somehow managed to keep telling me what happened.
"He's just as talented with his tongue as he is with his cock," Mom said.
Aunt Sabrina reached for mom, "God sis, you have a beautiful pussy, let me see your body."
Mom and Aunt Sabrina stopped masturbating and helped each other get completely undressed.
"Oh my god," Aunt Sabrina said when she saw mom's tits, "I always knew they were big, but I never really thought about how they looked. How did you get so fucking lucky? All I have are these."
Aunt Sabrina cupped her tits and frowned a bit comparing them to mom's.
"You have nothing to be ashamed of sis," Mom said. "Your tits are perfect, they fit your body perfectly."
"But yours are so much nicer. And bigger." Aunt Sabrina said, reaching forward to gently caress mom's tits. Mom enjoyed the feel of Aunt Sabrina's hands on her. She slowly reached out and started to fondle Aunt Sabrina's chest.
I guess I should pause here to tell you about Aunt Sabrina. She's mom's younger sister by three years but looking at them you wouldn't know they were related. Mom is a tall buxom redhead, while Sabrina is a short perky, athletic blonde. Mom took after her mother in looks and her father in height, while Sabrina was the exact opposite. She got her father's looks, with blonde hair and blue eyes, but was short like her mother. For scale, I'm exactly six feet tall, mom is 5' 9", and Aunt Sabrina is only 5' 4". She was a cheerleader in both high school and college and after college became an aerobics instructor, so she always kept in shape, and was still teaching classes. Much like mom she didn't look her age, at 47 she had the looks and body of a woman half her age.
Anyway, back to the story.
Aunt Sabrina ran her hands over her older sister's body, "God sis, I never realized how gorgeous your body was."
The last time mom and Aunt Sabrina had seen each other naked, mom was four and Sabrina was one when their mother would bathe them together. It was around that time mom was able to take baths by herself, so she didn't have bathtime with her little sister anymore.
"You're not so bad yourself." mom said, running her hands over Aunt Sabrina's body. "I have a confession to make. I've never been with a woman before."
"Never?" Aunt Sabrina asked, "You never experimented? All the sex you've had, and you've never had pussy?"
"No, I was too busy fucking every guy I could get my hands on until I met Ken. I thought about it, I even fantasized about it, but I never tried it." Mom admitted.
"Do you want to?" Aunt Sabrina asked, "I've been with a few girls, I could show you a few things."
"Wait, weren't you the one chastising me for fucking my son just a few minutes ago?" Mom asked.
