A Whole New World (Futa/M, excessive size/cum, non-consensual)

Another story...this one had been sitting unfinished for months, but I was able to finish this part up thanks to the feedback on my other story (Little Sister's not so Little Problem). This one has WAY more exposition than usual. Be forewarned that the sexual acts/endowments/abilities of the futa are all over the top, and that in this particular story the sex is non-consensual. Lemme know what you think!

------------------------------------

I watched out the window as my flight rapidly approached the runway. For most of the flight, I had been calm, but the end had me a bit nervous. I was about to meet my aunt for the first time...a person I would be be living with from now on.

I should probably give you a bit of background information. My name is Mark Stevens. My mother died when I was quite young from an illness and my father just left me due to a drunken accident. The former is something I still get sad about sometimes. The latter...not so much. My mother was a gentle and sweet person. My father...a drunken abusive asshole. So, in many ways his death was actually a positive thing for me. But here I was, about to move in with a woman I had only met through Christmas cards and live in a country I barely knew....yeah, I had reason to be nervous.

After collecting my bags I saw a woman near the exit holding a sign that had my name on it. While I saw her resemblance to my mother in her face and height, the rest of her build was quite different. She was a short plump woman looking as nervous as I felt. By the way, when I say 'plump', I don't mean fat. She just had an exaggerated hourglass figure that stood out compared to both my mother and the other Japanese women around her.

She noticed me right away, which wasn't particularly hard. The only genes I seem to have gotten from my mother was my attitude. The rest of me was stocky build, fair skin and blond hair, all from my dad. She came up and hesitated, not sure if she should hug me or not. I decided that the sister of my mother deserved a hug and gave her a gentle squeeze, which seemed to calm some of her fears.

She was rather quiet as she helped me with my bags and led me to the train. When she did speak, it was in decent enough English. But I told her that I spoke Japanese very well. This seemed to make her more comfortable. Her English skills (or lack of, in her mind) embarrassed her. She made idle chat with me, but didn't dare approach asking how I felt or anything like that.

The train didn't have an actual stop in Aunt Riko's town, so we had to take a taxi. It was quite a drive. Towards dusk we came to what looked to be a small-ish town. I noted the interesting mix of older and 'classic' structures amongst far more modern buildings.

Aunt Riko paid for the ride and helped me upstairs to her modest apartment. I was disappointed to see that her living room was smaller than my bedroom back home had been. And even more disappointed that my ro
