I could feel the stimulation against my button, but the sensations were oddly muted. Frustrated, I adjusted impatiently, using various angles and adjusting the pressure. Same muted sensations. A pleasant buzz over my nethers, but nothing more. In desperation, I slid the vibrating toy completely inside my slick channel and pistoned it back and forth inside me. Nothing. I clenched my teeth. This wasn’t happening. THIS WASN’T HAPPENING! Jaw locked, breath hissing, I worked my pussy relentlessly. Still nothing. Distressed, ready to scream, I bit my lower lip in frustration. My hips bucked involuntarily. I gasped, having a sudden epiphany. I moved my hand to my mouth and slid my thumb between my lips. Lights flashed behind my closed eyes and I knew I was on the right track. I wrapped my swollen lips around my thumb and worked my mouth on that thumb the best I could. Almost instantly I was rewarded with a breath-taking jumping of my belly muscles as my pussy clenched and lubricated in response to the crazy sensations coming from my over-stimulated lips.
