It was a warm Sunday morning and Billy was sitting in the front passenger seat of his mother's car, the sun beaming down through the windshield. They had just left church after another long service. Billy fidgeted with the radio knob, flipping through stations.
"You did so good today honey, sitting through that long service," his mother said, smiling at him. "I think you deserve a special reward, don't you?"
Billy's eyes lit up. "Really? What kind of reward?"
His mother bit her lip and gave him a mischievous look. "Well, I was thinking...you could have a little fun with Mommy if you want."
Billy's face flushed red. He knew exactly what his mother meant. They had done this before, when she was feeling extra affectionate after church.
Feeling bold, Billy reached over and placed his small hand on his mother's thigh, rubbing it through her skirt. "Mmm, Mommy's legs feel so good," he purred.
His mother smiled and took her hand off the steering wheel, placing it on top of Billy's. She guided his hand to move up and down along her thigh.
"Now why don't you pull up Mommy's skirt so you can feel her soft skin, baby? You know Mommy loves that."
Billy's heart raced with excitement. He slowly pulled up his mother's skirt, revealing more and more of her long, creamy thighs. They were so smooth and warm.
"Does Mommy feel good, sweetie? You can hump me now if you want to," she purred, giving him an encouraging look.
Not needing to be told twice, Billy scrambled over the center console to straddle his mother's lap. He grinded his hips against her thighs, his little erection poking through his shorts.
"Ohhh yeah baby, hump Mommy real good," she moaned, guiding his hips. "Mommy's gonna make you feel soooo nice."
They dry humped like that for several minutes, Billy's face buried in his mother's neck. It felt so good to rub against her.
When they both were thoroughly satisfied, his mother gently pushed Billy back over to his seat. She pulled her skirt back down and smoothed her blonde hair.
"That was fun, wasn't it baby? Such a good boy for Mommy," she praised, giving his thigh a squeeze. Billy could only nod, his face still flushed.
He knew they would likely do this again next Sunday, and he couldn't wait. Being a good boy and pleasing Mommy was the best feeling in the world. Billy smiled to himself and gazed out the window as his mother drove them home.
