While the thought of being the only man alive in the whole world was rather tempting, I knew that there would be dire consequences if that was true. Because of that, I only decreased the city's male population.
Most of the men still living within the city were those that needed to take care of and provide for their family, or ones working in intensive labor or important jobs.
Although not having any other male besides me, the number of passengers in the train car didn't feel any less than it normally did.
Also riding the train to school were the other students wearing their new uniforms.
Wearing a short shirt and an armband with the school's symbol, the female students didn't have anything else on them besides their school bag, shoes, and socks.
Since I increased the beauty, boobs, bounce, and butts of every female in the world, even some of the formerly underdeveloped female students had some bounce and jiggle to them whenever they moved. Especially so when they weren't wearing much in terms of clothing.
Because the train car was getting crowded, the boobs and butts of some of the passengers were rubbing against each other. Due to also increasing their sensitivity, the passengers easily became hot, hard, and wet after receiving such a small stimulation.
Since I was sitting, I had a great view of someone's slightly wet pussy and jiggling jugs. That person was a member of the school's swim team, she had long straight black hair with some hair underneath and milky white skin with an almost invisible swimsuit tan.
"Would you like to sit with me?" I asked the student while she was getting slightly pushed and shoved by some of the other passengers.
Although my question seemed harmless, it wasn't; triggering something I previously wrote within the notebook.
"Yes please, thank you." Gratefully accepting, the student moved to squat above me before placing my penis to the entrance of her vagina; using one hand to hold my penis, while using the other to balance herself with the wall.
"No problem," I said while nonchalantly placing my hand on her round ass.
"Nmph~, Thank you anyway." She said while smiling and sliding my now overly massive dick inside her.
Besides for my own pleasure, I started sucking her boobs to help her get wetter.
Even though we weren't physically moving, I was able to enter deeper inside her after becoming fully erect. Although her pussy was already soaking wet and she was sliding it in slowly, it was still painful taking my massive penis deeper. But due to having her sensitivity increased, that pain was somewhat masked with pleasure.
Because of the intense pain and pleasure, she stopped herself from going any further; trying to catch her breath while using having both of her hands against the wall to keep herself balance since she was shaking.
Due to the enhancements I made to myself, taking two-thirds of my dick was enough to enter her womb.
Not wanting to wait, I grabbed two hand fulls of her ass before slamming my dick into her; reaching down to the base of my dick and reaching the walls of her womb before pushing even further and making a visible penis head shaped bump coming from her stomach.
"Ahhhhh~!!" Feeling the sudden pain and pleasure of having her womb broken into and stretched, her eyes rolled back while arcing her back.
Meanwhile, I could feel her vagina squeezing and squirting.
With her being an athlete and formerly a virgin, the tightness of her pussy was already amazing even after tightening even further from coming.
After bringing her closer and keeping her from falling, I started slamming her pussy with my massive penis; hitting the walls of her womb and stomach with every thrust.
Not stopping my thrusting until was about cumming... I slammed my dick deep into her womb without hesitation before releasing a huge hentai sized load that filled her womb to the brim and more.
Continuing to use her as my cumdumpster until we reached are station, she became barely able to talk or stand since she was inflated with my semen. This was due to the combination of having my massive penis always inside her and the tightness of her pussy barely letting the semen in her womb to escape.
Since I couldn't leave her here, I carried her and are bags to school.
Walking to school, my penis was still inside her pussy the whole time. Although sleeping soundly with a very happy and lewd expression on her face, she still had her arms and legs wrapped around me.
Because my physique was the absolute peak that was humanly possible for someone my size, carrying her to school wasn't hard or tiring at all.
After leaving her with her friends and watching them "clean up" the mess I left inside her pussy using their own mouths, I went to class.
