Diana had just unlocked the office and was setting up when the doctor entered in through the back door. Their first patient was due any minute. He didn't even say hello, just, "stand up." When she did, he came behind her, pulled her pants down, and thrust his hard dick in to her waiting pussy without warning. It was lucky that she had rubbed one out in the car before going in to the office- her pussy was wet and willing. The doctor held her head down on the desk with one hand, and got a good grip on her hip with the other and began to thrust in and out briskly.
Diana moaned as he pulled backward and gasped as he thrust in, the pleasure overwhelming her senses. His dick was so fucking good. He mumbled, "Yes, slut. Take that dick" and she felt the building orgasm take over her body. She shivered and bucked against his body as the orgasm flowed from her pussy to her brain and back, the juices flowing from inside her and dripping a slow beat on the floor. The doctor lifted her by the hair and turned her head enough to smash his mouth into hers, forcing his tongue between their lips to mingle with hers. He reached his other hand around to her breast and tweaked her nipple hard, and the first orgasm rolled into another. She groaned deeply and he began to groan as well. She tried to pull back and tell him to pull out, but he held her neck and came deep inside of her pussy.
He stayed inside her while they caught their breath, and then pulled his still-hard dick out. Their mingled cum spilled out of her and he handed her a few tissues to clean up. He took a handkerchief out of his breast pocket and wiped off his shining dick, and then pulled up his briefs and pants. Diana adjusted herself and blushed when she made eye contact with him. He studied her for a moment before he stepped closer to her. With one hand he reached out and held her jaw, and the other down to grab her pussy through her scrub pants. "This is mine now, yes?" he asked, but it wasn't much of a question. Diana nodded, dazed. "I do what I want, when I want, with this pussy. Yes?" he said. She nodded again. He grazed a thumb over her full lower lip and said, "And this mouth, that's mine too." He leaned further forward and took her lip between his teeth, and then kissed her roughly.
Diana couldn't breathe. She stood very still as he had his way with her mouth, only wishing that he'd pull her pants down and fuck her again. He pulled back, though, and gave her lip another nip.
"Good," he said softly, "I think this is going to work."
