Kate and Sara were watching us with their mouths open. I could see the shock on their faces. I could feel Amy's large breasts encased in a bra rubbing...against me. My knees were shaking and my cock was so hard. My step mom turned me around and started to kiss me hard. He tongue just pushed its way into my mouth without even a second wasted and built up in intensity. I could feel her breath coming faster and her tongue started to probe my mouth. My cock was hard against her soft tummy and I was. Nor was the number itself. The caller ID simply said "Private Caller." She had made them wait to leave a message as long as possible, to screen out those who didn't really want to talk to her. Most people, including telemarketers, wouldn't wait past about ten rings. She gave her customers the code that, when keyed or spoken, would send them directly to voice mail. So this wasn't a customer.She told the phone to give up the mystery, her finger tapping the screen, and she listened as the voice. I was embarrassed somehow, but I managed to take my top off slowly, while having my tits covered by my arm, then I was taking my hand off slowly revealing them, and I went back to work as if nothing happened, but the man was going crazy, his eyes mesmerized on my bare tits all the time, he did not leave me alone for a single moment.The next step came a little faster than I have expected, he offered me another 25% extra per hour for taking my pants off and work with only my panties on, to make. . His face was so close. Close enough to reach out his tongue and taste her, if that was something he desired. It was something hed never done. Something he thought submissive. Distasteful. But more than once hed found himself alone in his bed, fist around the length of his cock imagining what his sisters cunt would taste like as she came. It would bother me very much. Her voice was thick, and when he looked up at her, her eyes were wet and she was biting her lip. Confusion was apparent on her.
