At one o'clock, Bill knocked on the door. "Ready?"
"Sure am!" Nina exclaimed happily. She locked her PC, grabbed her bag and walked to the door. Together they exited the building and made their way to his truck. He opened the door for her and she settled in. He climbed in, started it up and put it in drive, the destination unknown to her. She assumed it was to their usual spot at the park.
Bill eyed her in the passenger seat, noting her slightly opened legs and lips. She was learning well; one of her lessons was to be ready for him at all times. She was never to have her legs or her mouth closed, as they should always be open to accept his hardness whenever he felt like giving it to her. Seeing her there, open, wearing his collar, dressed as a schoolgirl got him so hard he felt like he was going to split his skin.
"Undo your shirt. Let me see you." Bill watched her intake of breath, knowing she did not want to obey here out in the open. Her fingers rose tentatively to the buttons of her shirt and she worked them reluctantly. Soon they were all undone and her shirt gapped open except for where her seatbelt held it tight. Nina breathed harshly and kept her eyes cast down, unwilling to meet the gaze of any passing drivers that might see her like this.
"Spread your shirt. Put those beautiful tits on display for me."
Nina pulled her shirt open, tucking the edges against her sides. This put her breasts fully out in the open, exaggerated against the seatbelt holding her tight. She bit her lip and clenched her fists, wanting to please Bill yet fighting against her nature to cover up.
"Good girl. You are beautiful, and the world should see you just like this. Stay there."
They continued their drive, making their way down the now familiar route to the park, Nina exposed to all who happened to look. They passed a few folks who did double takes and then immediately shook their head disbelieving what they had seen. After a few minutes, they pulled up next to a truck going the same way at the red light. The driver looked down at Nina and almost spit out his coffee. He caught Bill's eye and smiled big, nodding his head in approval. Bill smiled back and cocked his head, in an invitation to follow. As the red light changed, Bill pulled ahead and the trucker melted into the lane behind him, unable to resist the temptation of seeing where this would lead. Nina, her eyes kept down in humiliation, didn't see the exchange or the truck behind them as they pulled into the park.
Bill brought the truck to a halt, wheels crunching on the gravel. He put it in park, shut off the engine and pushed his seat back, providing ample room behind the wheel.
He turned to look at Nina, "Are you still grateful for my gifts?". As he asked, he noticed the truck pull in beside them, although Nina, lost in her own thoughts didn't notice.
She looked at Bill and breathed, "Oh yes, I am grateful. May I show you?"
