Brynley jerked as his fingers explored her folds slowly, methodically. Treatments? Realization dawned on her. The swollen breasts. The urges. The copious moisture. The soft puffiness that she had begun to take notice of in her nether regions. The prof smirked, withdrawing his fingers and stepping back. She almost whimpered at the loss of contact. “I see you’re beginning to understand. So, I offer you this- allow me to satisfy your urges, and plant my seed.” She didn’t know what had come over her, but it certainly wasn’t common sense as she urgently tugged him back to her, covering his mouth with hers and relishing the feeling of his body against hers once more. Her shorts and panties were gone quickly, and he had gripped her thighs and lifted her onto the student desk behind her in quick order. He stopped just as suddenly though. “Lay on the desk.” He ordered, leaving her panting and protesting as he stepped away to his own desk again, giving her a sharp look when she didn’t listen right away. He disappeared from her sight as she lay back reluctantly. She heard him rummaging in his drawer for a few moments before she felt his presence once more. “Lay still.” He murmured, lifting her legs and spreading them apart, lewdly displaying her in her entirety. “This needs to be done optimally.” He continued, brushing his hands over her thighs. She jolted as she felt a cold liquid, though not at her ‘typical’ entrance. Rather the much tighter one further down. He was quick to admonish her mild protest as he swirled the slippery fluid over the creases, barely teasing at entering the tight ring. “I need to know that your temperature is appropriate for this process. So please don’t mind the probe, though it is larger than a typical thermometer.” Suddenly he was smoothly thrusting the probe in, going a little deeper with each thrust. It felt cool and metallic. But its presence wasn’t… unwelcome persay. More unfamiliar. But filling. Especially once he had sunk the object to its base.
