He does, then Shelby lends him a hand

Richard snapped. He grabbed Shelby's head and pulled her into him for a powerful kiss. While their mouths got reacquainted he reached down and frantically undid his trousers.

As soon as his cock was free, Shelby grabbed it with both hands and jerked him ferociously. Her whole body bounced wildly, but he held her close so they could continue kissing. She twisted her head continuously, kissing him one way then another as she ran her hands over his steel hard cock.

Shelby pulled back, but didn't slow her handjob at all. “God! I love how big this cock is! Do you still fancy me, Richard?”

“Fuck yes!” said Richard, trying not to scream it. He let his hands fall from her head to her chest. Her breasts were small, but very pert. Even through her blouse and bra he could feel how erect her nipples were. All his worries disappeared as the lovely redhead serviced him.

Shelby recognized the far away look in Richard's eyes. Keeping one hand working his cock, she leaned sideways and picked up the small wastebasket next to his desk. She held it next to their legs and pointed his cock at it. Seconds later he burst, arching his back and sending streams of hot white jism into the basket.

The Irish girl smiled with satisfaction as she climbed off her teacher and set the wastebasket back.

“Well,” she said casually, “time for lunch.”
