I can't get the word "porcio" out of my head, something I heard from a friend in the neighborhood. I thought the reason I wasn't satisfied with sex with my husband was because I was frigid. But I discovered that deep inside the uterus is the porcio, the erogenous zone where women feel the most. Then, one day, I met up with Sugiura-kun, my school sweetheart. When we had sex back then, it was too big and didn't fit in. Maybe Sugiura-kun's penis could reach my porcio... Just thinking about it made my body heat up and numb...
