Adrian knew what he was about to do could get him fired, not to mention how Sally's father might react if he caught the two of them. He didn't care. Sally was hot and he found her partial shark transformation strangely erotic. Adrian slowly turned in Sally's grasp, unzipping his pants as he did. He wrapped his arms around her and kissed her hungrily. Sally returned the kiss in kind even as she guided Adrian into her.
Adrian was amazed how tight and wet Sally was - no wonder she was so eager to fuck! Sally pushed Adrian's back against a nearby wall, almost knocking over a table in the process but not letting him slip out of her. Adrian's hands slid down Sally's back to grasp her firm ass cheeks and thrust. Her hips pushed back against him. Over Sally's shoulder Adrian could see her shark tail flailing around. Their animalistic wall bang ended when Sally bit Adrian in the neck. It wasn't enough of a bite to draw blood, but when it happened both Adrian and Sally orgasmed. Adrian could feel Sally's body pumping him for all he was worth until he was completely limp.
They clung to each other against the wall for a few minutes in the afterglow.
"That was...intense..." muttered Adrian.
"I can leave the gate unlocked if you want to come back tonight after daddy's asleep" suggested Sally. "After midnight should be safe. We can got for a swim..."
"I don't think I'll be recovered by then" Adrian lamented. "How about tomorrow night?"
"I look forward to it." Sally kissed Adrian before backing away with a toothy grin. She walked gingerly toward the pool and waded back in.
Adrian watched her go, enraptured. He pulled up his pants, quickly gathered his things, and made haste for the front door.
