欲求不満な発情おばさんに誘惑された僕は……。～秘密と背徳に満ちた冬休みの思い出～（Yokkyuu Fuman na Hatsujou Oba-san ni Yuuwaku Sareta Boku wa... ~Himitsu to Haitoku ni Michita Fuyuyasumi no Omoide~）

That winter break, since my parents were working, my aunt Yuko and uncle Tomohisa moved in for a while. I was looking forward to this!
They're so much fun when I visit their house, now they're here for a whole vacation.
I especially loved aunt Yuko. She was so pretty she could be on TV.

The first night, she got in the bath tub with me. I got an erection. I was getting a lot of those recently. She had this look in her eyes and breathed a long, hot breath. Her eyes got all soft, like she was overheated from the bath. She drew herself close to me. Then she said, with dripping wet significance, "I can't hold back any more."

She leaned down and coiled her hot tongue around my penis.
It felt like all of my insides suddenly dropped. I had never been so dizzy.
It was a good feeling like I can't describe.
That time I had my first ejaculation ever.

After I finished cumming, not entirely sure what happened,
I thanked her for the amazing gift. She smiled gently. She said,
there's so much that she's going to teach me.
Of course it had to be secret from uncle Tomohisa, and mom and dad.
She was nothing like the aunt Yuko who I thought I knew. Every
word had a dense, honeyness. The way she said "secret" made
me feel deep and and dizzy like when my penis was in her mouth.
An obscene embrace in her smile and desire.

It was a winter break I will never forget in my life.
