The magic semen

I was 22 years old, I was a young white hairless guy with a slim body and a nice ass, I was straight although I did not flirt much because my physique was not very dominant or masculine.

Recently some construction work had begun in my neighborhood and I walked in front of it every day on my way home from college, I had never stopped to look at the work carefully.
Until one day on my way home I passed by the construction site and a worker who was resting bumped into me, when I looked at him in the blow I saw that he was a man of about 30 tall and big, wearing a white tank top that was tight because his big muscles almost did not fit in it and you could see through it all the body hair that covered his body because he was all sweaty.
After the blow I apologized and got ready to continue on my way home, but the man stopped me and asked me if I was from the area, I said yes and as I was leaving I noticed that he kept looking at me for a while. I didn't think much of it.

After this event the man was always looking at me and waiting for me at the time I was coming home, and one day he approached me while I was coming back and I noticed that the man had a big erection and a big stain in the crotch of what looked like semen, I saw him accelerate my pace home, but he ran faster and stood right in front of me, at that moment I noticed a smell that I found very pleasant was in the air and that smell left me a little stunned without paying much attention to the man who was in front of me, it was then when the man invited me to have a coffee at his house and gave me a paper with the address and just when he gave it to me with the other hand he hit me on the shoulder, after he left I continued my way home, but I was still stunned because the smell was still in the air and I had almost not heard that the man had given me his address.

Then when I was changing my clothes at home I saw that on my shirt in the shoulder area there was a stain of something that I did not know what it was, but when I saw it I had the need to smell it, it emitted the same smell that stunned me and I liked that smell, it was then when I saw the note with the address that the man had given me a few hours ago, and unconsciously I decided to put the stained shirt back on and go to that address.

When I arrived I knocked on the door and the man who was waiting for me opened it, he was shirtless exposing his big and muscular pecs covered with a strong and curly hair, and his abs that were also covered with the same hair, when he saw me he invited me to go to his room and I was stunned by the smell and I went in and sat on his bed and he slowly began to undress me, but when he took off my shirt I came out of that trance state and I got scared, I was shirtless in front of that man 

I was shirtless in front of that big man who was not wearing a shirt either, then I got upset and I was ready to run away as soon as possible, but the man threw himself on me lying me on the bed and he was on top of me, I tried to escape, but he was twice as big and muscular and he could handle me, then he started to tell me: come on don't worry this is going to end up liking it and it will change your life.

On top of me the man started to grow a big erection in his pants, when suddenly he pulled it out and put it in my face, and when I smelled the precum that emitted from his big penis the smell controlled me and I couldn't help licking his big penis, I could not believe what was happening, I could not control my body, while I was sucking him the man finished undressing us leaving us completely naked and I kept licking his big penis as if it were a melting ice cream, until little by little I introduced the whole thing in my mouth.

I gave in to the control of the smell and taste of precum, I completely lost control of my body, I was at the mercy of the big man, then he ordered me to get on all fours, I got on all fours and he began to lick my asshole, his tongue was moving inside me, which was starting to cause me some pleasure and his beard was rubbing against my naked buttocks and my bare and flat, it was then when he turned me abruptly leaving me on my back and he was right on top of me and started to tell me, you would like to have such a big and hairy body, and you also want men and for them to penetrate you, I could not speak or tell him that I did not want men and that I did not want to have a hairy body, but the man after this put me back on all fours grabbing me by the neck and suddenly he put his penis with great force in my ass, that caused me a great pain that turned into pleasure quickly, which made me let out a big moan, then the man began to move his big penis inside me while I noticed all over my back as his body hair rubbed my skin and everything made me enjoy it more and more, the man was accelerating the pace until suddenly he released all his semen inside me, I noticed how that liquid ran through my interior, it was then when the man stood up next to me with a jump and stood looking at me while he said to me: I was motionless lying on the bed noticing how the semen ran down my ass, when suddenly I began to notice how it was absorbed until I stopped noticing it inside my ass, my body had absorbed it and just at that moment my whole body began to ache my muscles tingled my skin burned and my insides burned and I began to scream from the pain while the man kept looking at me, it was then that I began to notice that I was getting bigger, my muscles were also growing my hair began to grow and brush all over my body, after suffering this change I became unconscious.

After a while I woke up the man was gone and when I got up naked, I saw myself, I was covered with body hair, a strong and curly one my muscles had grown and were defined and I was bigger.
When I saw this I ran out and went home scared
