Erin's birthday was coming. Saturday she would be eighteen. Erin is a beautiful young woman, with long brown hair and dark flashing eyes. Her breasts are not huge but they would more than fill my hand, if she weren't my sister that is. Erin's body flows down from those lovely tits into a slim waist that flares into womanly hips and an ass that would attract any man's eye. So, it attracts my eye. Sue me.
Erin is a younger version of our mom. Mom is graying and doing some strategic sagging. To me she is still hot and I love her more than words can say.
Mom's name is Delores and I am Jesse. Erin is my little sister; in fact, I am nineteen years older than her. We've always told my sister that our dad left right after she was born but the fact is that he left just before I turned eighteen.
The day after I turned eighteen, Mom came to my bed and slid beneath the sheets with me. Mom's nightie was thin and I soon discovered that there wasn't anything under it.
"I'm lonely Jesse. I don't see you talking to any girls your age. Are you lonely too? I mean horny really." She molded her hot body against mine and I felt her tits against my chest. I had my arms around her as her lips touched mine for the first time. I didn't feel a bra strap across her back. I didn't expect one really. As my hand slid down to her hip and then to her ass, I noticed that there were no panties either.
"I am horny Mom. You are too?" My cock was trying desperately to tear a hole in my plain white briefs.
"Yes honey. Would you feel OK about making love to your own mother?"
I answered by kissing her and trying to probe her mouth with my tongue. My hand that was on her ass was moving the thin nightie up and over her back and as our tongues got used to their little dance, she shifted so that I was able to remove what little clothing she had on.
My mouth was on her breasts in moments and I sucked as I tried to shuck off the only piece of clothing I had on. Mom's hands assisted me and we were both naked in a moment. She moaned and held my stiff cock as I suckled at her sweet mammaries and then gasped as I headed south over her soft belly toward the delta of hair between her legs.
"Honey, you don't have to do that. Oooh." My lips had found her clit and I kissed it over and over before I spread her wider and sampled the wetness between her folds. "Ah, Ah. Oh Jesse. That's nice." She let me feast on her tender flesh for a few minutes before she gently pulled my mouth back to her love button and I knew that it was time to make my mother cum. My tongue lashed her stiff nub over and over as her hips rocked to get just the right spot worked repeatedly.
Just as two of my fingers slid past her nether lips, Mom let out a long loud moan that signaled her completion.
I stayed where I was for a few minutes, just taking in the scent of my mother's cum. I realized that my cock was harder than it had ever been and at that same moment mom spoke.
"Baby. Your cock was so stiff even before you made me cum so hard. Are you ready to fuck my soaking wet pussy? I need it. I'll suck you off another time."
I was up and on top of her before she even stopped talking. As I sunk into her to the hilt, Mom grunted and I did too as I started to fuck her. Mom's legs were wrapped around my back and I could feel her tight muscles urging me on to the finish line.
"Inside you?" Was all I could get out.
"Yes Baby. Cum in my pussy."
That was all she wrote and a giant stream of sperm laden semen flooded my mother's vagina. Mom had another orgasm as I finished inside her and I stayed in her while she continued to cum.
After I rolled off and we regained our breath. Mom said, "Wow. I really needed that. You're a great fuck honey. Did you enjoy it?"
"Are you kidding? I'd do that again in a heartbeat."
"Looks like I'll need to do a little work to make that happen." Mom said, looking at my soft, cum smeared penis.
We laughed and then we slept.
In the morning, true to her word, Mom was working hard on my dick. I could tell that she was kind of hungry from all of the activity of the previous evening. I let her continue with her ministrations until my climax was imminent.
"Here it cums, Mom," was all I got out before I let my stream bathe her tongue. I knew she'd swallow but I was so proud of her for not letting any of my seed escape.
She snuggled next to me with a satisfied little grin on her lips. We slept for a couple more hours before my stomach growled loud enough to wake us both.
We got up and took a quick shower together before I went to the kitchen to cook us both some breakfast.
"Man, I can't believe that Dad left a hot lady like you to bone somebody else." I cuddled Mom while the hash browns crisped up in the frypan.
"Well, about that, honey. The man that you've always called Dad, isn't your biological father. You know how I came to you horny last night? My Daddy came to me soon after I turned eighteen because Mommy wasn't giving him what he needed. Well, I had what he needed between my legs...and other places. I gave it to him willingly and in a couple of months, he gave me you, baby."
My eyes were like saucers and I took in the story. She told me some of the things that they did together. I couldn't keep my cock down when she told me about the first time, he slid his prick into her butthole.
"You take it in the ass Mom?"
"Yes son, your mom likes anal sex. There's not much I not willing to do for a man that I love."
"Can I start sleeping in your bed from now on Mom? I love being so close to you and your bed is nicer too."
She laughed at my practical observation and gave me a tender look about my wanting to be so intimate with her. "I was hoping that you'd want to move into my room Honey. Yes, let's live as if we're a married couple.
It had been a few months and we were getting to know each other's needs and desires. Mom didn't want to have intercourse when her menstrual cycle came and I would only get one blowjob in that five- or six-day period.
One morning, Mom bolted out of bed and ran into the bathroom. I woke up slowly after hearing the door slam. We had taken to peeing with the door open but I thought maybe she had an urgent poop coming on. It was quiet enough in the house that I could hear the sound of her vomiting. I wondered if she had eaten something that gave her food poisoning.
Mom opened the door while she was brushing her teeth and I saw a look of concern in her eyes. After she rinsed and came back to the bed, I asked what was worrying her.
"Baby. After my Daddy and I had been screwing for a few months, I missed my period and then started throwing up in the mornings for a week or more. I went and got a test and found out that I was going to have you. I told Mommy and Daddy that I had gotten fucked by a guy I knew and that I was pregnant. Daddy acted mad so as to not blow our cover and Mommy said they would support whatever decision I made whether to keep it or end the pregnancy."
"When Daddy and I were in private he told me that his preference would be to keep you and He'd help raise you as much as possible."
"We did just that and I lived with them until Daddy died young a few years later. I'd had a boyfriend for a while and Mommy encouraged us to get married. That was the man that you called Dad."
"I feel the same way this morning as I did on those mornings almost nineteen years ago. You may or may not have noticed that I didn't start my period a couple of weeks ago like I always do. I'm nothing if not regular."
"Baby, I think that we're pregnant. How do you feel about being a father...and a brother?"
Speechless doesn't even describe me at that moment. My mouth hung open as my thoughts whirled around like a tornado.
Mom leaned in and helped me close my mouth by kissing me repeatedly. I smelled her fresh, toothpaste smell and felt her soft tits on my chest.
I hugged her and asked, "Were you and Daddy able to make love while you were pregnant?"
Mom laughed and rolled to her back. "Is that your biggest concern? You're worried that you might not be able to fuck your mother because you knocked her up?" Her legs came apart and she welcomed me on top of her. I was so excited about everything that I just took my pleasure with her, only concerning myself with my own orgasm.
