After about two hundred hand spanks she told ...e to stand up. “Drop those pants to your ankles and be quick about it.” My nervous hands struggled to release my buckle and work the zipper while she tapped her foot. She looked motherly with her hair back and her sleeve rolled up. I pushed my pants down and then went back across her denim lap. Once she had me in position again she really started.
