My girlfriend practices her moves on me to better please her boyfriend

As any young lad, I'm fortunate to have a smoking hot girlfriend who's always eager to please. Not only is she a vision to behold, but she's also a master in the art of oral pleasure. But here's the twist - she uses me as her practice dummy to perfect her skills for her boyfriend! One fateful day, she decided to hone her blowjob techniques, and who better to learn on than her stepbrother? As she sank to her knees, her brunette locks cascading over her shoulders, she eagerly took me into her mouth. Her lips worked their magic, her head bobbing in a rhythm that left me breathless. The sight of her swallowing me whole was enough to drive any man wild. As she continued her oral escapades, I lay back and savored the sweet taste of my girlfriend's lips. The thought of her doing the same to her boyfriend sent a thrill down my spine. And as she brought me to climax, she eagerly took my cum into her mouth, leaving me in a euphoric state.
