I shoved my big-assed mother on the subway

My name is Fernando, I’m 20 years old. This story happened when I was 17 and in high school. There are three of us in my family: my dad, my mom, and me. My mom is a very beautiful woman with an amazing body, large breasts (I think it’s a C cup), smooth, white skin, and long, dyed blonde hair. But what stands out most is her incredible ass. For 38 years old, it’s firm, hard, and well-defined. My obsession with that ass started when I was 17 and we went to the beach. My mom wore a nice-sized bikini, nothing revealing, but because of her big butt, it was too small. I spent days watching that ass move, sit, and stand up, and from that moment on, my dream was to have sex with it.

This happened to me, as I mentioned, when I was in high school. I remember it was a Friday. That day, my mom had to go to school to sign my report card. Report card signing was from 10:00 a.m. to 5:00 p.m. The problem was that my mom works at a bank, so it was difficult for her to go. Even so, she asked for permission and they gave it to her; she would arrive around 4:00 p.m. That day, the students got out early. As soon as our tutor arrived, he would sign, and we could go with him. So, my mom was one of the last to arrive. She signed, and we headed home. Usually, every day we go in the car with my dad. He drops me off at school, then drops my mom off at work, and on the way back, he picks her up. Since I get out earlier, I take the subway.

It was around 5 o’clock that day, so my mom said to me, “Hey, I forgot my money at home. I only have about 100 pesos. How much do you think a taxi will cost?” I replied, “Well, if it’s far, I think around 150 easily. I only have about 20 pesos. Since we left early, I didn’t bring any more money. Hmmm, but we can take the subway. We’ll get there in about 30 minutes.” She responded, “Okay, although it’s about to get busy, let’s go before it gets crowded.” The station is about three blocks from my school, so we got there, scanned our tickets, and waited for the train on the platform. More and more people were starting to arrive since it was getting late.

The train arrived, and since it was already quite full, we had to stand. There were about 12 stations to reach our destination. That day, Mom was wearing her work clothes, which consisted of a black miniskirt, sneakers, a white shirt, and a black vest. Even though I saw my mom’s ass every day in that miniskirt, I never got tired of it because her panties were so prominently visible, whether they were cheeky briefs, thongs, or large panties. When she bent over or squatted, I had the pleasure of seeing her ass in all its glory.

As more people boarded, we got closer and closer together. At one point, we were right up to the corner of the train car. My mom had her back to me and said, “We should have taken a taxi and paid when we got there. We’re packed in like sardines.” I replied, “Oh well, it doesn’t bother us. It’s normal for me; I almost always travel like this in the afternoons.” Then people started pushing harder and harder, so I ended up behind her. I said, “Sorry, Mom, but people are pushing really hard.” She said, “It’s okay, I hope the train moves quickly.” With the movement of the car, I started rubbing my mom’s buttocks, and little by little, I got an erection.

I felt embarrassed and tried to move away from my mom’s buttocks a little, but it was impossible. When they pushed suddenly, I would let my erect penis fall onto her buttocks. After a while, I didn’t care anymore because it was the other people’s fault. My mom was clearly uncomfortable; I don’t know if it was because of how tight it was or because she felt my penis on her buttocks.

As I got more aroused, I think I was processing things better, because for the first time I had the opportunity to put my hands on my mom’s buttocks. Carefully, I started to lower my hands until they were level with her buttocks, and with a rolling motion, I began to rub them. I couldn’t believe how firm they were for her age; I felt like my penis wanted to ejaculate a liter of semen. After a few minutes, I stopped so she wouldn’t suspect anything, because she didn’t say anything, but she looked uncomfortable. Since my penis was very tight in my pants, I slowly started to unzip them and peek out so I could have more direct contact with my mom’s ass. With the heat of the moment, I didn’t care if people thought I was sick.

I grabbed it with one hand and started pushing at the level of her anus, fantasizing that I was fucking her in the ass. Then she said, “Hey, can you move back a little? I’m being crushed.” I got scared because I thought she had noticed, and I said, “We’re in the same boat. I’ll try, but I don’t think I can.” I waited a while, but it was still as hard as a rock. I tried to look down and saw how her ass stood out so big that it turned me on even more. At that moment, people started getting more and more agitated as they went in and out. In one of those many movements, I took the opportunity to touch her legs and also lifted her skirt a little. Her hands were occupied; in one she carried the folder with the tickets and in the other her purse, so she couldn’t adjust it.

Carefully, I lifted her thin skirt enough to see her panties. That day she was wearing green thongs with lace trim. The moment I saw them, I almost came from excitement, because those thongs looked like they were about to burst, my mother’s breasts were so big. I rubbed my cock against her for a while, and a little precum started to leak out and smear itself on her buttocks and panties. I knew I couldn’t do anything more; it was already too much. I was fulfilling a fantasy of rubbing my cock against those big buttocks, the ones I’ve jerked off to so many times. Carefully, I tried to position my cock between her legs so that at least it would brush against her delicious pussy.

I did it carefully, then, using the excuse of the other people around, I started moving forward and backward so that the head of my penis slowly slid between her legs. When it was level with her pussy, I started moving a little faster. I couldn’t hold back for even two minutes before I came. I stained her panties with my semen, as well as her legs, and some of it dripped onto the floor. I couldn’t believe what had happened. There were only about two stops left before we got off, so I pulled down her skirt and put my flaccid penis back in my pants. At the time, I didn’t know if she had noticed because she didn’t say anything or make a sound. At the exit, we managed to get off the train amidst pushing and shoving. It’s about four blocks to her house. She didn’t say anything on the way. When we got home, she went to her room, changed, and took a shower a few hours later.

Everything seemed normal, although she didn’t speak to me for most of the night. After that, I went to take a shower and looked through the dirty clothes for her panties. I saw her thong; it clearly had a large semen stain where her vulva is. It was obvious she noticed, but she didn’t say anything. The next day, everything was normal.
