When my best friend's girlfriend lay sleeping innocently beside me, my groin could no longer restrain its impulse. I wished she would let me treat her as my own, and a mischievous desire began to stir. As she woke up, her plump, defenseless ass spread openly right next to me. While her boyfriend slept nearby, I boldly took her into my mouth, unable to stop the stimulation. What started as mere teasing turned serious. Enthralled by her lewd figure, I lost all control—there was no turning back.
