As it happened, the inestimable Sheila Monroe, my wealthy client called and asked if she could sit for her painting that afternoon. I'd laid in the ba...kground and washes, and I was ready to start on the detail work, so I agreed and Sheila arrived about noon.She didn't bother to step behind the screen I keep in the studio for changing, but made sure she had my eye first then began simply taking her clothes off in front of me. This was a portrait that showed down to nearly her waist, but she took. She closed her eyes and moaned as fingers rubbed her crotch through her wet panties. One of the women tried to kiss her on the mouth but Grace backed away. “Not yet, not yet. Maybe later,” she whispered, laying her finger on the woman’s lips, caressing her messed up hair.She got up from the bed and turned around. Two older couples were sitting on a large couch enjoying their champagne, watching Grace’s little foray on the bed. She slowly moved in front of them and handed her empty glass to one. It felt as though May was watching her, too, although Mary could not imagine it was possible to see her in the darkened corridor. She was biting her own lip hard, an intermittent tiny squelching noise from her slippery pussy being the only sound she was making.Mary had touched herself before, especially during a summer a couple of years ago, when she was sharing a room with her beautiful cousin Suzanne (without the other girl ever realising she was masturbating in the bed next to hers). But. .. Uhm... It’s...”Melissa knew she had him on the line. She just had to reel him in. She popped open a button on her blouse, and then a second. His eyes darted up and down between her face and her revealed cleavage.“Well?” she asked. “Is it a deal? I show you my tits, and you forget I was up here?”Charlie hesitated for a second, and then comically nodded his head yes.“Okay,” she said, and went to work on the remaining buttons.The young man’s eyes followed her every movement. He was so caught up.
