Jessica didn't know what had gotten into her, but she knew what she wanted into her. She had been horny before, but never so horny for sex. Sure, she had been attracted to Adrian before, but something about seeing Adrian's big gray shark cock unlocked a new sexual hunger within her. She rode Adrian slowly at first, trying not to hurt herself. With her hands on Adrian's shoulders and Adrian's hands on her hips, Jessica steadily worked Adrian's shark cock deeper and deeper into her.
Adrian tried to thrust with her, but he felt a bit like he was being used as a shark dildo. Not he minded too much. His engorged member was incredibly sensitive. Adrian felt his eyes starting to roll back in his head. He tried to say something, but all that came out was an animalistic grunt/moan.
Jessica came down with one final thrust, driving Adrian deep within her. She felt his body quiver, felt him explode within her. Her body shook in response and she forcefully kissed Adrian as the only way to stifle a scream of pleasure that she was worried might otherwise bring security. The orgasms washed over her like waves. When they stopped, Jessica slumped against Adrian, both of them spent.
After several minutes to recover, Jessica dismounted. She stumbled on her feet, weak in the knees and aching between her legs. The braced herself against Adrian's desk and took deep breaths. After she composed herself, she put her clothes back on. Adrian was still dazed and feeling drained.
"That was...holy shit..." Jessica panted. "But we better go."
Adrian blinked, still trying to get his own bearings. "Where?"
"I think I'm the only one who can drive right now," said Jessica. "Let's go back to my place."
Adrian wasn't about to pass up that invitation. He fumbled with his pants and let Jessica lead him out to the parking lot.
At Jessica's apartment, they headed straight for the bedroom, but not for any more amorous pursuits. Exhausted, they both collapsed on the bed and were fast asleep in minutes. Jessica's last thoughts before falling asleep were wondering why she hadn't experienced any sharky changes yet. Maybe in the morning?
