You can decide if this story is fact or fiction. I’m not going into flowery details here. This is a story about lust, not romance. Only the most relevant events will be shared.

To be clear, this is my biological mother. I literally mean the woman who carried me for nine months, pushed me out of her vagina, and raised me. That mother.

Her name is Cristina. She is 41, 5’1 tall with a curvy and voluptuous petite body. Her hair is chestnut brown and reaches just past her shoulders. Her tits are heavy and round from motherhood and breastfeeding. Her ass is full and round too and protrudes slightly when she wears heels. Her teeth are white and straight, and her nose is slightly long with an Italian-heritage shape. Her voice can be sweet and soothing, but harsh and shrill when she gets angry and yells. She is a housewife and never worked since she married my father.

My father is a Sales V.P., so he is often traveling for work and can be gone for days at a time. It was my mother’s job to keep the house in order while he made the money. As a result, it was usually just me and Mom at home.

It all began when I was 18. In the summer, while my father was out of town for the week, Mom was doing her usual housework for the day. When she entered my bedroom, I was sitting at my desk doing summer schoolwork (I had failed math that year). Her hair was tied back in a bun, but she wasn’t wearing her usual housecoat or casual clothing. She was only wearing a black bra and black panties. This was the first time I had seen my mother so brazen with her body around me. She seemed to completely forget herself as she looked around my room for any loose laundry to place into the basket she carried in her arms.

“How is your homework going?” she asked.

“Uh, good,” I said while trying to hide the growing erection in my pants. Did she even realize what she was wearing? And in front of her own son no less!

“You need to work hard after failing math this year,” she replied while leaning over to pick up a sock on my floor, giving me a perfect view of her ass in the panties.

“Yes, I know,” I mumbled while trying to get a peek.

“Your friends all passed, and your father and I are very disappointed in you,” she said casually as she walked toward the door.

I didn’t respond.

She turned back towards me, giving me a full-frontal view of her body. “I still can’t believe my own son would fail a class! You are such a disappointment.”

But I wasn’t listening. I had heard the scoldings many times before. No, I was hyper focused on the female body in front of me. I had never seen my mother like this. She was freely offering me a view of her large, heavy tits barely contained in the bra and a thin line of her brown bush just above the waist of her panties. Sufficed to say, she left very little to the imagination.

I didn’t even notice when she finally turned around and left my room. My heart was pounding like mad, and the only thing I could think about was my mother’s body. My homework became an afterthought. There was only one thing I wanted now, and that was my mother.

Of course, I know the rules of society. Mothers and sons don’t (we assume) have sexual relationships with each other. This was true in my household too. Mom never made the slightest sexual advances on me, and I never imagined what her body looked like naked. That is, until that day in my room.

Since I knew that nothing could ever happen between Mom and I, the next best thing was watching mom/son porn videos online. The ones that stood out to me the most were the impregnation videos, where the son would give his “mom” a huge creampie and potentially get her pregnant. Of course, these were all just actors. It was obvious that none of these “moms” were actually getting bred by their sons.

That summer, I developed a routine to feed my curiosity about Mom’s body. Since I would get home from summer school around 3pm, Mom would just be leaving to go buy groceries for dinner that night. I decided to be bold and sneak into my parent’s bedroom while she was out. I knew that I was never allowed in my parent’s room for privacy reasons, but I just couldn’t help myself.

I walked into the ensuite bathroom and found the laundry hamper sitting in the corner. With my heart pounding and my hands shaking, I lifted the lid of the hamper and looked inside. There was a pile of worn bras and underwear inside, sitting on top of some other loose clothing. I reached inside, my hand still shaking, and picked up the black bra on the top of the pile. It was still warm, which meant Mom must have just changed out of it. I pressed the soft cups into my face, taking a deep inhale. They smelled like a mix of sweat, skin cream, and ladies’ perfume. I took another deep inhale, letting the scent of her tits fill my lungs.

Next, I put the bra aside and reached deeper inside. I found the matching panties, also still warm from recent use. I held them out in front of me and began examining the crotch. There was a clear yellow stain where her vagina had rubbed up against it, but it was unclear if that was her pee or vaginal discharge. I could smell the strong scent of it, like urine mixed with a hint of fish. It made my dick hard instantly and drew me towards it. I pressed the crotch to my nose and took a deep inhale of Mom’s vagina. It was so intoxicating that I thought I might faint. I instinctively reached into my pants and started touching my erection. The precum had already seeped into a spot on my boxers, making my shaft slightly wet and slick.

I reached deeper into the hamper and found another pair of her panties; this one was likely worn several days ago. I took an inhale of the crotch, but the stain in the center had already dried and lost most of its intoxicating scent. I pressed the crotch of the fresher one into my nose again and took a deep inhale, then used the older pair to jerk myself off. The fabric of her panties felt soft and slick as my precum covered the crotch with each stroke. I tried to imagine Mom in my room again, wearing the panties I was smelling right now, scolding me about my grades. Her heavy tits barely covered by her black bra, the shape of her round ass abundantly clear from how little her panties covered her, and even the line of her pubic bush that peeked out of her crotch ... all of it was a tsunami of arousal for me.

As I felt myself about to cum, I took one last inhale of the panties in my face and let myself erupt into the ones around my dick. My strokes slowed as the cum in my shaft made its way onto Mom’s dirty panties, soiling them even more with my seed. When I was finished, I used the cum-soaked panties to wipe myself up and placed them at the bottom of the hamper. Mom wouldn’t do laundry today, so there would be plenty of time for it to dry before she noticed anything. I placed the dry pair back on top of the pile in the hamper and made my way back to my room.

I wish I could say that was where it all ended. But smelling and cumming into Mom’s dirty panties just made me want to fuck her even more. I started learning her daily routine so I could plan my attempts to sneak into her room without getting caught. The grocery store, the car wash, the drycleaner ... I memorized them all and knew how long each one took before she came home. A few minutes after she would leave, I’d enter her bedroom and go straight for the hamper. I’d bath my senses in the scent of her freshest panties, then use the older ones to make myself cum. I’d imagine what she looked like without her underwear, the sexy petite body that she barely hid from me that one time. By the time Mom came home from her errands, I would already be cleaned up and back in my room pretending to do homework. As far as I knew, she had no idea what I was doing in her absence.

One day, when my father was home and we were all sitting at the dinner table, he casually mentioned that he was going to the doctor before his next trip. He said he was having trouble sleeping and was prescribed sleeping pills when he traveled. I assumed it was because of the constant time changes he had to deal with for his job in sales. Aside from that, I didn’t give it much thought.

Meanwhile, my obsession with Mom’s body continued to burn. As much as I loved smelling and cumming into her dirty panties, the novelty was starting to wear off. I really wanted to see her naked and even take some pictures of her naked body if possible. But this was a lost cause. Mom kept her bedroom door closed and locked while she undressed and showered, so there was no way I could ever get a peek let alone a clear set of pictures.

I did some research and found a cheap, small hidden camera online. It was cheap enough that I could afford it on my part-time summer job salary, but also small enough that it could be hidden somewhere in the house without detection. Since I was always home from summer school when the mail arrived, I collected the package without Mom ever noticing. When I opened the box, it didn’t seem as small as I had hoped. I could hold it between my index finger and thumb comfortably, but it was still big enough where it could get noticed if not hidden well enough.

When Mom left for one of her daily errands, I snuck back into her bedroom to find a good spot for the hidden camera. My heart was pounding like mad as I searched every corner, every hidden or covered spot I could find in her room that might conceal the camera. It had to be a good spot because, if Mom or Dad ever found it, there would be hell to pay.

After fumbling around for what felt like fifteen or twenty minutes, I finally decided on the perfect spot. It was in the ensuite bathroom in the corner of the wall behind the bathtub, tucked slightly behind a fake plant and a few candles Mom had bought years ago but never lit. Mom never took baths and always preferred showers, so I wasn’t worried about her checking in that spot out of chance or habit. Plus, since the plant was fake, she never had to get close enough to water it. The camera would be nestled safely behind these forgotten items, watching and recording her most private and intimate moments.
