The girls walked ahead of me to the front door, my daughter leading up the steps to the porch.

As her friend Katie took the final step onto the porch, I was three feet behind her.

My eyes focussed on her tight cantaloupe sized buttocks, and an involuntary “tsk” escaped my mouth. Turning surreptitiously Katie looked me straight in the eyes, a naughty smirk playing on her lips.

That night, stroking my cock under cover of darkness, my wife sleeping next to me, all I could think of were Katie’s warm, wet, milky white pussy lips parting to my cock.
