First Love: A Single Dad Next Door Romance

"My sister warned me to stay away from this trusting girl next door."
However, what she didn't factor into this situation was that I'd fall head over heels in love with this girl.

Her hot skin tantalized my sleep. Your moist, luscious lips begged for mine to wed hers when I tried to concentrate at work.
I could hear her tinkly laugh in my dreams. How can I get out from under her spell?

What am I going to do? There's no happy ending in sight no matter which path I take.
