Spying On And Blowing My Son

I am a single mother of a teenage son. I was worried about my brooding and moody teenager. I spied on him from outside his window because I thought he was depressed or using. When I saw him masturbating I was so relieved. Seeing his beautiful cock made me become very aroused. I tried to put it out of my mind but I couldn't stop thinking about his huge meat. He is much larger than his father. So, every time he went to his room I snuck outside his window to watch. In the fall I was outside his window and it was open a little to get air in his room. He laid there caressing and stroking his beautiful cock and with the window open I can here him mumbling and moaning. I put my hand between my legs as usual. I was so wet. As my fingers slid over my hood I closed my eyes. I put my other hand over my mouth to muffle my gasps and moans. When I opened my eyes he wasn't on the bed. He then appeared fully nude right in front of me. He huge cock was only inches from my face with a thin pane of glass between his head glistening with pre-cum and my watering mouth. "Mom? What are you doing?"

Looking down at the ground I stammered, "Ummm, I was just looking for my earring I dropped earlier. How did you know I was out here?"

"I smelled your perfume..."

I looked up at him in the window and he was still naked in all his glory. Still stroking his hard cock. He wasn't ashamed or apologetic. He was showing off. He opened the window the rest of the way and then the screen. Now there was nothing between my mouth and his raging hard on. He began waving it in my face taunting me, hypnotizing me. As I leaned up against the window sill he moved his cock closer to my face.

"You like what you see, Mom? I know you've been watching me! You want it don't you?" As he continued to hover his cock less than an inch from my face.

I was trembling. I wanted it so bad. I wanted to taste every inch of him. I was so frustrated from my son torturing me. I couldn't believe he was doing this to me. I looked up at him and saw the devil in his eyes, in his smile. Tears of frustration filled my eyes. I felt a tear run down my my cheek. I felt lightheaded. I couldn't resist anymore. I felt so weak. I grabbed it with both hands and took as much of him as I could into my hot wet mouth. I could taste his sweet pre-cum! My son grasped my hair and moaned in ecstasy. I sucked, kissed, and licked my son's beautiful and perfect cock. He began to slowly fuck mommy's mouth. When he would thrust, he would thrust harder and harder. The further he pushed in the wetter I became. When his mushroom head spread my throat open I tried to hold it down as long as I could. When he pulled it out I gasped for air. My boy kept fucking my mouth. As he kept sliding in and out I fingered my pussy. It didn't take long. My knees started to shake. I started to moan louder and louder with my son's cock in my mouth. The more I moaned the more my son moaned and thrusted.
I started to cum. My pussy was squirting into my hand and my yoga pants were drenched. I continued to take his cock to the balls. He then started to shake. "Mom! I'm gonna cum!" He pulled out and started shooting streams of cum across my face and tongue. I tried to catch it all in my mouth. It was so fucking delicious and there was so much. When he finished I sucked the rest of the cum from his fat mushroom head. I looked up at him with my cum covered face. He looked down at me with that devilish smile. He smeared the cum on my face around with his cock. I was so intoxicated. I stood there and let him paint my face with his sweet sticky cum. When he was finished he stepped back and closed the window. I stood there with cum on my face and soaked yoga pants. I looked at my reflection in the window, eye makeup running, lipstick smeared, strands of hair glued to my face with cum. An overwhelming feeling of guilt and shame came over me. I fell to my knees and started to sob. What have I done?
