I never knew my mother. She died from a rare complication after delivering me. In the first 4 years of my life, I was mostly raised by a nanny and later, by my father, Marco. He was a construction worker who was allowed to finish earlier than usual to care for me when I got back home from school. When I was 12, I was old enough to stay alone at home, and Dad returned to a full time job. As I started junior high, Dad became a supervisor, and his job description, salary, and benefits improved.
I, Leon, was a small guy. In my junior high I was barely 5'6" and 150 pounds. Frequently, I was picked on by other students and mocked for being a pretty sissy. Whether it was the reason or the result, I rarely associated with other boys and found refuge in the company of girls. The girls saw me as one of them, and we used to chat and gossip much of the time.
My Dad was my ideal man. He had an imposing presence: At 6'3", he weighed 200 pounds of pure muscle. Whenever I was with him, people moved away, scared shit of his stature. However, with me he was very gentle. I still recall one time a big brute from a class above harassed me for refusing to give him my ball before leaving school. He slapped me in front of a cheering crowd. All of a sudden, out of nowhere, Dad showed up. He grabbed the bully's neck with his huge palm, looked at him and asked menacingly, "Hey moron, did this kid do something to you that you hit him?" The trembling guy tried to free himself but to no avail. Dad called me and said, "Leon, he slapped you once, so go ahead and hit him back any way you wish. And if I ever hear that anybody, and I repeat ANYBODY, touches you again, let me know, and they better move to another country before I reach them." Since that time, I was treated more respectfully in high school.
Once I asked Dad how come I was so much tinier than him. He looked at me with pity in his eyes and said, "Your mother, god bless her soul, was pretty, but also small. You inherited her genes. We cannot change it, but I can work with you to become more muscular and better prepared for the rough world." He worked with me 3 times a week with wrestling and boxing, and he made me join a health club too. Slowly, I became bulkier and stronger.
In senior high I turned 18. I was doing quite well in school. I applied and got a letter of acceptance to U of I for the following year. I was very happy.
...
In my senior year I was still socially inept, and after school I hardly got out of my house. Most students saw me as a nerd who invested his time studying and hated 'manly things' like ball games, wild partying, and cursing in public. I was less inclined than before to join girls because the fact they looked at me as one of them offended me and gossip started boring me.
When the summer vacation began, I joined Dad at work for a day. He commanded a group of 10 employees who were working on renovating an old building. Dad wasn't supposed to do manual work and only supervise others, but he used tools and labored like everybody else. He removed his shirt and worked hard in the scorching sun. His rippled muscles glistened, and I was taken by his amazing body. Much of the time, I ogled his manly sweating figure. By the end of the day, I told Dad I was impressed by his dedication and hard work.
He smiled, "I like showing my employees I am one of them. It creates a team spirit. In addition, we finish the work earlier and get a bonus."
As we got home, he entered the shower. Five minutes later, I needed to pee, so I entered the bathroom as well. Dad was soaping his body behind the foggy glass. I peed while my eyes were glued to his body. His dark skin, massive chest, abdominal 6-pack, and bulky quadriceps were all awesome and reminded me of a depiction of Hercules I once saw. Then Dad slowly soaped his genitals. The heavy, hairy ball sack and the long, thick soft penis were hypnotizing. My eyes were mesmerized by the way his hands spread the soap and then washed the area. I didn't realize I continued staring at his groin after finishing my pee. I overstayed in the bathroom. Later I went to my room seeing Dad's junk before my eyes. I masturbated thinking about it...
When we ate dinner, Dad seemed to be oblivious to me being in the bathroom while he showered, and we talked about my plans after college. The next day, Dad went to work as usual, and I spent my day exercising and then going to the library. I came back home at 4 pm. My father returned half an hour later. As usual, he first went to shower. Like the day before, I entered 5 minutes later and began peeing. When I was done, I continued inspecting Dad's naked body through the steamy glass.
Suddenly, I heard him say, "Leon, if you wish to stay here, be of use. Grab the loofah and do my back."
He opened the glass door and turned his back to me. I rubbed his neck and continued down to his muscular back. I stopped when I reached his lower back, but he blurted, "Continue. You are not done yet." With trembling hands, I soaped his firm ass cheeks and knelt down to work on his legs.
Then, I stood up and planned to leave, but Dad turned to me and said smiling, "You did a good job on my backside. Now do the front."
I gazed at him pleadingly, but his eyes did not budge, "Leon, you find my body interesting, so now you have the opportunity to see it up close."
I sighed and started soaping his neck, gradually moving to his chest and tummy. Next, I knelt again and did his shapely legs. Now and then, I glimpsed at his glorious tool. When I was done, his organ seemed to harden somewhat. I stood before Dad. He whispered, "Son, finish the job you started."
"...Dad..."
"You'll leave after you are done!"
I grabbed his partially soft member and gently soaped it, followed by doing his ball sack. It took me about a minute, and during this time I noticed his pecker stiffened further. When I finished, I looked him in the eye.
He grinned and blurted, "Leon, you did a nice job. Now go to your room, and the next time you have the urge to ogle my naked body, you'll be told to soap me again."
I blushed and left the bathroom humiliated. The rest of the evening, I felt bad, and eating dinner with Dad was a quiet torture.
Later in bed, I tossed and turned for an hour until I fell asleep. During the night I had a dream in which I was desperately chasing Dad's cock, but as I approached it, it disappeared. I woke up horny and jacked off before attempting to go back to sleep. Before dawn, I had another dream: My father walked nonchalantly in the house wearing only a shirt but no pants. His magnificent prick was swaying from side to side like the hand of a metronome, hypnotizing me to stare at it. I tried my best to avoid looking at it, but I couldn't. Dad caught me, and grinning, he ordered me to soap him again. I woke up covered with cold sweat.
For the next 3 days, I did everything I could to stop thinking about the shower episode, but I was unsuccessful. I tried to rationalize the event and came up with 2 options: Either I was attracted to my father's body, or I was gay. Unfortunately, I had nobody I could talk to about it; my father was the only one I fully trusted...
On the fourth evening, I gave up my fight. A moment after I heard the water pouring in the shower, I entered the bathroom and stood there. I didn't even pretend to pee. I just stood still with my eyes concentrated on Dad's phallus. He smiled at me, shut off the water, opened the glass door to the shower, and glanced at me. He didn't say anything, but the hint was clear. I entered the shower. He faced me and blurted, "Leon, no need to wash my whole body. Clean only the area you are interested in."
With my face beet-red, I soaped his sack and dick, washed it thoroughly and then looked at Dad's face. He smiled, "You can leave now, and we'll talk later." With my heart pounding like crazy, and my cock hardening, I rushed out and sat in the living room. I looked blankly at the TV screen with Dad's member floating before my eyes.
Dad exited 10 minutes later wearing shorts and a tee shirt. He sat by my side, hugged my shoulder, and asked softly, "You seem to find my penis very attractive. Am I right?" I stayed mum with my eyes focused on my shoes.
He whispered, "That's OK, son. I am not upset. There is nothing wrong with being curious. Here, let me make it easier for you." Next, he removed his shorts, and his genitals were now fully exposed. His cock looked slightly bigger than before and aimed forward. He took my closest palm and placed it on his rod. "You can touch and massage it if you wish."
I hesitated and then gingerly trailed his growing organ with my fingers. My lips got dry. I licked them and swallowed my saliva. I lowered my gaze to his groin. Dad's fingers caressed my cheek and then moved gently over my full lips. His light touch was very erotic. I parted my lips and took his thumb into my mouth. I sucked on it mildly.
Dad chuckled, "Son, you are no longer a baby. You are an adult now. Adults do not suck on fingers; they use a larger size tool. Go ahead."
My head was spinning: Dad instructed me to suck his penis! I liked its size and shape, but I wasn't gay. Was I?... The touch was pleasant: It felt velvety, with the veins bulging out and the helmet somewhat larger. My brain told me not to do it, yet my mouth wished to taste it. Dad just showered, so the smell and taste won't be bad... After a couple of minutes, I leaned my head on Dad's lap and aimed the now more engorged tool onto my lips. It smelled faintly musky and fresh. I kissed it. It jolted, and a drop of precum appeared on its tip. I licked it. It tasted very mild.
