Marks POV:
Anna: "Mark, why it always hard..?"
(I looked at Anna for her first matured question, but she still hides her face on my chest.
I can sense her jelly boobs are squeezing to my body...
How can I not be erected..?
It's time to tell her that I fall for her when I first saw her, maybe it's called love at first sight, but I didn't realize it by then,
She is happy for my explanation and looking at me with her blushed face...
I told her how I feel when I saw tears in her eyes...
I told her my every emotion, and I also explained to her why my dick erected...
But one of her questions shocked me that when my dick will get normal.
I visualize how I fantasize and fucked her in my dreams and how I masturbate myself when she is sleeping.
