Taking a probe

Another week of Johanna using her breasts to service the needs of her patients had passed, becoming a part of her daily routine. It was just another one of those days, she was on her knees pushing her full breasts up and down the patient's strong, hard cock when she felt a hand on her head. It was the doctor's old, but authoritative hand that grabbed hold of her thick brunette hair and **** it toward the patient's aroused member. She tried to struggle against his firm grip, but he held fast, until the head of his cock brushed against her lips. Johanna still fought him until he finally commanded her in a stern voice, "Be a good girl".

At his words, all resistance drained out of her and she opened her mouth to accept the patient's hard shaft. The doctor kept pushing down on her head as he guided the man inside her, and soon Johanna felt waves of pleasure run through her body as she began to revel in the sensation of the cock in her mouth. Before long, she could feel him begin to twitch and soon he filled her mouth with cum. "Don't swallow yet!" the doctor said firmly and she obeyed. "Open your mouth," he ordered and when she did, a huge load of semen was revealed there. He took a swab to collect a sample and then looked at Johanna with his beady eyes. "Now swallow it," he commanded and she did, before being sent away.
