MILF Fucks her Sons Friend

The description should be written in a first-person narrative, and should also include a bit of backstory and dialogue to make it more engaging.

I was walking home from work when I saw Dava Foxx leaving the house next door. She was wearing a tight, low-cut top that showed off her incredible, fake tits. I've always had a thing for her, and I could see she was looking a bit down. I knew I had to make her day better. I knocked on her door and she answered, looking surprised. "Hey, Dava, I saw you and I wanted to check in. You seem a bit stressed out," I said. She sighed and let me in, "I've just been having a tough day. My son's friend has been acting out and it's been driving me crazy." I felt a surge of excitement. "You know, I might be able to help with that," I said, winking at her. She raised an eyebrow but smiled. "Oh yeah? How's that?" I asked, "Well, he's been having trouble staying focused in class. I think he needs a little... motivation. I think you might be able to provide that." She bit her lip, considering. "I have a proposition for you. If you can keep my son's friend in line, I'll let you watch me. I'll give you a show you'll never forget." I was in heaven. I agreed without hesitation. I met her son's friend at his house. He was a cocky kid, but I could see the potential. I promised him that if he could keep his grades up, I'd give him a reward he'd never forget. He agreed, and I knew I had to make good on my promise. I went back to Dava's house, and she was waiting for me, her top off, her fake tits bouncing as she walked towards me. "Ready for your reward?" she asked, her voice sultry. "You bet," I said, grinning. She pushed me down on the couch and straddled me, her fake tits in my face. I could feel her pussy grinding against my cock. She leaned in and whispered in my ear, "You like that, don't you?" I nodded, my cock throbbing. She smiled and grabbed my cock, stroking it slowly. "You're going to love this," she said, and then she took me into her mouth. I groaned as she sucked me, her fake tits jiggling. She was a pornstar in every sense of the word, and she was going to give me a show I'd never forget. I couldn't hold back any longer, and as she continued to suck me, I came, my cum shooting down her throat. She swallowed it all, her eyes locked onto mine. "You're a good boy," she said, "Now, let's see if you can keep my son's friend in line." I knew this was just the beginning of a long, hot night with Dava Foxx.
