After my mother died, the father who raised me alone remarried. My new stepmother, Mary, was so beautiful and kind that she seemed far too good for him. Once we began living together, I secretly watched their nightly sex and found myself captivated by her insatiable appetite. Then one night, while Dad was away, she learned I was a virgin. Fresh from the bath with her hair still wet, she smiled, kissed me gently, and took the lead. She ground her hips from beginning to end and moaned through hard pile-driver thrusts as I came inside her again and again. Lost in my tireless stepmother's close, hands-on lesson, I kept climaxing until dawn, my legs gave out, and I had nothing left to give.
