He couldn't believe it. He was watching his gorgeous college student masturbate in front of him. No, he corrected himself, she was masturbating for him. He was suddenly very glad he was sitting behind his desk because he didn't think he'd ever been this hard. It was incredibly erotic to see her this way. To anyone else she looked normal, paying attention, taking notes. But he could see her getting wetter and wetter as her hand moved faster. He had no idea how but he was managing to teach without making an ass out of himself, although he could barely tear his eyes away from Dani's hand long enough to answer questions. Mercifully it was time for silent reading so no one noticed him staring at his student, at least not that he noticed.
She could feel herself spiraling towards climax. She looked up at her professor and the look of pure lust on his face sent her over the edge. She couldn't stop her body from shaking slightly and her lips parted in a silent expression of pleasure. To her surprise, instead of sating her needs that had only served to increase her desire.
"Class dismissed. Your only homework is to finish reading this chapter and the next one." Dani gathered her books and stood up. "Miss Alston, may I see you in my office please?"
She nodded and followed him into his office. He locked the door behind her and then pulled her roughly to him, his hands running down the length of her back and down under her skirt to firmly cup her ass as their mouths met in a smoldering kiss. She pushed her hips forward to grind against his heavy erection. She couldn't resist the temptation so she leaned away slightly so she could unzip his fly and let her hand curl around the length of him. She began a steady rhythm that elicited a moan from him. She was suddenly spun around and bent over his desk in a move so fast it made her head spin. Before she had time to regain her senses he gripped her hips and slammed into her from behind, making her cry out in pleasure. Giving her no time to adjust he set the pace: fast and hard. It didn't take her long to build up to her first orgasm. As it ripped through her she saw lights dance behind her eyes and her body shuddered.
He slipped his arms around her just in time to keep her up as her legs gave out. He lifted her and turned her around, setting her on the edge of the desk. Wrapping his arms around her waist to support her he once again slammed into her, picking up his earlier pace. Watching her expressions change, seeing her tilt her head back and bite her lip, watching the shifting of her body as she tried to get closer, she was driving him crazy. Her muscles tightening around him in her orgasm was the final thing that pushed him over the edge. He thrust into her and made both of their worlds shatter.
