The tension had been building for weeks. My 18th birthday felt more like a countdown than a celebration, all thanks to my step aunt, Sarah. She was a blonde bombshell with natural tits and a mischievous glint in her eyes. Sarah, with her white skin and a few delicate tattoos, had this way of making me feel both nervous and… aroused.
The party was winding down. Everyone else had gone to bed, but Sarah found me in the kitchen, nursing a beer. "Happy birthday, handsome," she purred, her voice a low rumble that sent shivers down my spine. She was wearing a silk robe that barely concealed her curves. I tried to make conversation, but my words caught in my throat. I wanted to tell her that she looks so hot in that clothes. Sarah leaned in, her breath warm against my ear.
“I have a special gift for you,” she whispered, tracing a finger down my chest. My heart hammered against my ribs. The beer slipped from my grasp, crashing to the floor. Sarah didn't flinch. She simply smiled, a predatory glint in her eyes. "Let's go upstairs."
In her bedroom, Sarah pushed me onto the bed. I was so nervous, my hands were shaking. Sarah straddled me, her weight pressing me into the mattress. "Relax, baby," she said softly. She began to kiss me, deep and slow, exploring every inch of my mouth. I moaned into her mouth as I started kissing her back. Her hand worked its way beneath my belt, unfastening it with practiced ease.
The world spun as Sarah took me in her mouth, deep throating me until I thought I would explode. I watched her, the fire in her eyes as she brought me to the edge again and again. "I am cheating my husband with you!" she said while she was swallowing me. Her grip was tight, her rhythm relentless. Finally, I came, a torrent of cum flooding her mouth. She swallowed it all, her eyes never leaving mine.
Sarah pulled away, a satisfied smirk on her face. She reached for a tissue, wiping her mouth clean. "That was just the beginning," she said, her voice husky. She positioned me doggy style and I let her do it, letting her dominate me. She pounded into me, her nails digging into my ass. I came again, this time all over her panties, staining the silk with my seed.
Afterward, we lay tangled in the sheets, catching our breath. Sarah ran her fingers through my hair. "Happy birthday, David PussyFuck."
