She's a hotwife

There is something deeply erotically charged about the way the word 'slut' forms on my wife's lips. About the way she passionately kisses another man while I watch her jaw move as her tongue lashes his and his hands move over her soft yielding body. Placing his hands on her shoulders he urged her to her knees and enthusiastically she unfastened his pants and sought his thick 8" cock before running her lips and tongue up and down his hardening shaft then taking the crown in her mouth and sucking on it excitedly. He brought her to her feet and pushed her back on our bed and took offf her panties and spread her legs before plunging his head between her thighs and licking her wet pussy eliciting moans and cries that had me hard as rock. When she was close he moved up her body and my heart stopped as, with one long slow deep thrust he penetrated my wife and began fucking her. Soon I watched her body shaking as orgasm roared through it. He wasn't done. Turning her on the bed he lifted her hips and brought her to all fours, her face toward me so that I could see her face contort with pleasure with each thrust and watch her lips frame every cry of "YES! FUCK ME" Until she collapsed forward clutching at the sheets as a second orgasm rocked her body. A few moments later with a few triumphant grunts and long deep thrusts he emptied his seed deep inside my wife. He rolled her again on her back and brought his softening cock to her lips. "Clean it, slut". From where I sat I could now see his cum seeping from my wife's well-fucked pussy while she took his cock in her mouth and tasted the rest of it along with her juices
