Brotherhood with my son - how it all started.

My name is Carlos, I'm 40 years old, I'm a cultured but sociable man, I have a body that is well articulated for my age. I usually train running and go to the gym frequently, I'm tanned because of the race, I'm 1.90 tall, light brown eyes, almost a green, military-style hair, a beautiful smile of a brave macho, broad and checkered shoulders, thick and hairy legs and an abdomen of envy in many boys half my age. With some rubbers and a beautiful chest with some grey hair as well as my abdomen that has the famous trace of bad way with thick hair and curls that from my navel until my smile turns grey. I like to keep them is my trait of masculinity, very soon they will come from the sweaty treadmill, I just open my pillows well and stay massaging my body of underpants and pulling my big man's hand with the nose full of sweat. I'm 18 years old, I'm married to a nice guy, and I've been sleeping with a nice guy, too. How did it all start? My son has always been a man full of energy, going out to parties and coming back late at night. Cadu lives with me on the coast of Rio Grande do Sul, in Torres. Often, on these outings, he came back accompanied by some girl. I heard the steps in the corridor and their discreet laughter. He thinks I never suspected, but I always knew. He would take the girls to his room, which is at the end of the hall, and I would imagine what was going on inside. Sometimes I would sneak out of my room, just out of curiosity, and listen to the typical sounds that conveyed the situation. I won't deny, I thought it was funny. "The boy pulled his father", I thought, and I would return to my room laughing alone. I slept quietly like a rock. The other day, it was as if nothing had happened. No sign of the girl, just the routine silence of the house. After one of those nights of Cadu, curiosity spoke louder. The next morning, after he left the house early, I decided to take a look in his room. I entered slowly, as one who does not want to be noticed, and I began to observe every detail. The bed was still messy, the gentle smell of female perfume hung in the air, mixed with the characteristic aroma of his environment. As I was quietly rummaging around, my eyes landed on the trash can next to the bed, and that's when I noticed something that caught my eye: a used condom, lying at the bottom of the trash can. It looked fresh, still full of sperm, the translucent material glowing slightly in the light coming in through the window. For a moment, I stood there staring at it, a mixture of surprise and curiosity took hold of me. That's when I brought the condom close to my face, and smelled my son's liquid, and in that instant my dick hardened like a stone in my underwear. The sweetness of his fuck made me crazy, out of my mind. For a second I thought about experiencing guilt, but it consumed me. I had never done anything with another man or anything related to what I was doing. I left the condom in the same shape it was before and found it in his room. This memory lingered in my mind for days, weeks and months, until I began to realize something that I hadn't paid much attention to: I had always been a very organized man, both with my work and with my home. My clothes were always meticulously organized, my suits, my necklaces and even my underwear. I noticed that over time my underwear disappeared, only a few remained, and soon after they reappeared. I thought I was crazy. Until the day I stayed late at work. On this day Cadu kept my car because his was at the concert so he drove me early to the office and went to the college. The day started stressful with some petitions to be recorded, my intern was not taking care of the errand because this was his first internship in the area, so I had to assist him and at the same time try to reconcile with my affairs. The day seemed long. At the end of the day I called a car by app to go home. The driver drove me in front of the condominium, I went in and walked to my house and when I arrived I found it strange the fact of being at home on a Friday night because my car was parked in the garage. I went in without making a noise because I thought to myself that the mule would probably be with another girl and would not attract me. I turned off my shoes at the end of the hall to try to reconcile with my affairs. At the end of the day I called a car by app to go home.
