The day I turned 18 was an important day for me. Looking back, that was the day that I learned my true purpose in life. My stepdad waited for my mother to go to work and then he walked into the living room with his dick out. I had never seen his cock before and so I was shocked to see him stroking his dick with his right hand. He pointed at me with the other hand.
"Michelle, it's time for you to grow up and become a woman. Happy birthday to you."
"Um...thank you?" I answered, not really sure what he had in mind. I was afraid of his strange behavior and afraid of his large cock, which he was still stroking. "Why are you naked?" I asked, confused by his disgusting behavior. His cock was so much bigger than the guys I'd fucked that were closer to my age. I wondered how my mother handled it. I had no idea that I was about to find out.
"Get on your knees, right here." He pointed to a spot of carpet in front of him.
"But why?" I asked, afraid to move.
"Don't sass me, young lady. Get on your knees. Right here!" He pointed to the same spot in front of him and so I did as he asked. After all, he was my stepfather and I didn't want him to tell my mother that I wasn't listening to him. We hadn't always gotten along and my mother was very sensitive about my relationship with him.
"Good girl," he praised me. "Now open your mouth."
I did as he asked, opening my mouth nice and wide for him. I knew he was going to slip his cock into my mouth as I looked up at his crazed eyes. He looked possessed as he forced his dick past my lips and all the way down my throat.
I instantly choked, spitting his dick out and coughing as I attempted to draw in a healthy breath. "Why? Why did you do that?" I asked.
"You need to learn how to service me, Michelle. Your mom isn't here enough and we are always home alone together. We can help each other out. Now come on and get your mouth back on my cock."
I opened my mouth and this time he was a little more careful about not making me choke. He slid his cock in slowly and waited for me to relax.
"That's a good girl. Relax that throat. Take my cock as far as you can."
I was shocked when he pressed his dick deep into my throat. I stayed relaxed for him the way he asked me to and amazingly he was able to slip his dick down my windpipe. I panicked a bit, but he instantly soothed me, stroking my hair lovingly.
"Just relax. Breathe through your nose. Let it happen. I'm going to fuck your throat nice and slow, okay?"
