Filling mom’s panties with milk

This is one of the most exciting stories that I have had so far, my name is Joel, I am 25 years old, this story happened when I was 17 years old, it has been around for some time but wow, it was great, my mother’s name is Lorena, she was 39 years old at that time, she is an average woman, she is short, she has breasts that are not so big but enough to fill her bras, she has brown skin, not very pretty, as I said she is normal, what does stand out is her butt, it is big, round and very hard for her age, a great ass you could say.

Until that day, I never had any obsession with her. From time to time she would wear miniskirts and I would see her ass, how her panties showed. I did think about fucking that ass a couple of times, because at 17 you’re burning with hormones.

Well, my mom and dad are married, they have a good relationship, and I’m an only child. The story goes back to 2008. During the summer vacation, I remember that during those times, students usually have a month off, so my family almost always went on vacation somewhere. On that occasion, my dad said we should go to the mountains because the cold weather and clean air would be nice from time to time. Also, the beaches are crowded, so the mountains would be a bit more peaceful.

For that my dad invited his aunt (his sister) to make the trip more pleasant, with her would go her husband and her two small daughters, in total 7 people, the trip was scheduled to leave early on a Saturday around 8 in the morning, we would go in my dad’s truck which is somewhat spacious, but since we would be gone for about 2 weeks, and we would camp it is clear that we brought so many things that the trunk was full and we had to put suitcases on the passenger seats to be able to leave.

My dad and my aunt’s husband as well as one of her little daughters would go in the front, my aunt and her other little daughter would go on the right side, in the middle we put several suitcases on top of each other, so that there was only one place left and my mom and I were missing, one place and two people, the thing is that in a joking tone my aunt said, “sister-in-law go on Joel’s lap”, to which my dad and my mom saw it as a good idea, mom asked me if I had a problem with it, to which I said “well no”, the point was to go now.
Since the trip was about 3 hours long, and the summer was getting hot, my mom came out wearing a white dress that was almost transparent, against the light you could see that she was wearing some rather small panties, when I saw that I got kind of hard, but they quickly came down, for my part I was wearing some thin beach shorts to be able to ventilate well on the road, the fact is that we got in the truck and about 1 hour went by on the road, my parents and my uncles were talking but because of the heat my aunt and her daughters fell asleep, my dad and my uncle talked about politics and soccer.

In my boredom, I started thinking “hey, mom’s ass is sitting on your dick,” and well, her ass was a nice ass, so from that moment on I couldn’t get that idea out of my mind and I got really hard. I think mom sensed it because she started to move around a few times, apparently making her uncomfortable. When we got about halfway down the road, my dad said that a dirt road would start, made of dirt and rocks, so the truck would bounce and we should hold on tight.

With each jump the truck made, mom’s dress rode up more and more, even reaching a little above her thigh, then my mom took out her phone because she wanted to take some pictures of the road, when she grabbed her phone, the truck jumped and the phone fell under our feet, she said “wait I’m going to bend down to try to get it”, since the place was very small she moved the suitcases a little to make space, then she bent down and her skirt rode up a lot, but she didn’t notice.

At that I could see her big ass covered by black lace panties, which are less than 30 centimeters from my sight, at that moment I turned like stone, because she continued looking for the phone and moved that ass from one side to the other, I really wanted to move those panties aside to see her pussy and lick it, the most I could do was get just 10 centimeters or less away to smell. By that moment my penis had already secreted pre-cum and my shorts are more than stained because of it.

When she took her cell phone, she sat down on me again, she bent my penis so hard that I groaned, she asked me if it hurt, what she didn’t know was that her skirt was still so high that my penis was nicely under her panties, I knew because her entire dress was over my belly button, the sit hurt but I didn’t say anything so she wouldn’t adjust her skirt, I couldn’t believe that her pussy and my penis were separated only by her panties and my shorts.

The jumps of the truck became stronger, then I told mom that I would take her by the waist so that she would not go to the side or hit, and with each jump she would give a little jump and I would return her with a sit against my penis as if I were fucking her, when she moved the truck to the side I tried to rub my cock in her panties, the liquid continued to come out because it felt warm every time.

It was like half now between sits and heels to her beautiful panties that I could not hold it anymore, and I came like crazy, I grabbed her waist tightly and rubbed it hard against my cock, I felt like I was cumming inside her, she felt the cum I’m sure she put her hand between her dress but I realized and I moved quickly pretending that the truck jumped to avoid it, this could not end there anymore, I had to see those panties once more because it might be the last time, so I asked for her phone telling her that I wanted to take some pictures of the landscape because my cell phone was in my bag and I could not take it out, she said yes.

When she was going to give it to me clumsily I dropped it with the intention that she would bend down again, and so she did, I told her “what an idiot I dropped it, hey ma can you pass it to me”, she said yes, she bent down and what was my surprise my milk had wet her panties she had a huge semen stain on her panties next to where her pussy was, I got closer to smell it and in fact it was the smell of semen, I felt dreamy, then I quickly took my phone out of my pocket and took a picture of her upright with her panties stained with milk. When we arrived at the hotel in the mountains, we got off as if nothing had happened and every time I could I jerked off looking at those photos, wishing it would happen again.
