My mind flashed back to the previous day—the raw, animalistic sight of him fucking his girlfriend brutally on our bed. The image of him pulling out. His glistening, dangerous dick pulsing in the light was still fresh in my head.
Fuck! I couldn't believe I was sitting directly on top of it. We were separated by nothing but thin layers of fabric—the silky material of my floral gown and the cotton of his joggers. For a few minutes, the cabin was filled only with the hum of the engine and Henry’s mindless whistling, but then, I began to feel something thick and insistent poking my ass.
At first, I tried to lie to myself. Saying maybe it was a rod or a tool he had left in his pocket, but I knew exactly what was poking my butt. It was his fucking dick. He was getting hard because of me. The realization sent a dizzying rush of blood to my head.
I couldn't believe he would be reacting this way. Does it mean he actually finds me attractive? I’m thirty-five, and he was just twenty. How could he be getting hard for me? Apart from the age gap, there was the heavy, undeniable truth: I was his father’s wife. I was the woman who had helped raise him. This was morally wrong, forbidden, and completely taboo.
I was about to say something, to shift away or make some excuse to change positions, but then it poked me again. This time, I felt it differently. The rhythmic vibration of the car seemed to sync with the pulsing between my legs, and instead of pushing away, the contact ignited a wildfire inside of me. Fuck! I was loving it.
"Are you comfortable, Mom?" He suddenly asked with his low and raspy voice. "You’re free to adjust in any position you want."
His words felt like a green light. I adjusted, but I didn’t move away. Instead, I pushed my butt firmly back into his crotch, seeking out the source of that heat. I felt his dick poking me harder in response, a solid, unyielding weight against my flesh. I could feel the fire building, spreading around my core. I was getting wet, the familiar dampness beginning to soak into my lace panties. I was enjoying the contact far more than a good stepmom ever should.
I adjusted my butt more, shifting my weight from side to side. This time, it wasn't because I wasn't sitting well; I was shamelessly hunting for a better position to feel the full length of his strong dick.
I didn't even realize when I started grinding on him. It was a slow, subtle movement, disguised by the swaying of the car as Henry took the winding backroads. I could feel Randy getting even harder beneath me, his breath hitching in his throat.
"I can see you're finding a better position to be comfortable. I think it will be better this way," he whispered. He spread his legs a little wider, allowing me to sink deeper into the cradle of his thighs. This time, I could feel his dick perfectly, aligned right against the seam of my gown.
At this point, I couldn't help myself. I began to grind against him slowly, my hips moving in a small, agonizing circle. I could feel myself getting more and more horny with every rotation. I knew I should stop, that I should be the adult in the car and stop before it gets too late, but the thrill was too much to resist.
At a point, his hands suddenly gripped my waist, lifted off his lap a bit, and shifted his hips, lifting himself slightly, and when I sat back down, his dick was positioned directly under my core. It was nearly touching my pussy area, separated only by the thinnest barrier. The proximity made my head swim. He had wanted me to sit better and enjoy the ride.
"Are you guys okay back there?" His father asked, his eyes flicking to the rearview mirror. He sounded genuinely concerned, thinking we were just uncomfortable in the cramped space, totally unaware that we were finding a better position to do the unthinkable behind his back.
"Yes, Dad, she's just trying to find a better position, and I'm helping her so we can both enjoy the ride." Randy replied, his voice remarkably steady despite the tension.
As I continued to grind against him, emboldened by his response to his father, he placed his right hand firmly on my bare thigh while his other hand held my waist to steady me against the movement of the car. At this point, my panties were already soaked, the silk of my dress sticking to me.
My imagination began to run wild. I imagined him reaching down, pulling my gown up to my waist in one swift motion, shifting my underwear aside, and fishing his dick out to fuck me right there. I imagined the sensation of him filling me while his father focused on the road ahead. The thought sent a fresh wave of shivers down my spine, causing me to drip even more.
I noticed his hand was trembling slightly on my thigh, but he wasn't moving it higher. Maybe he wanted to, but he didn't have the courage to take that final step. To help him, to show him exactly what I wanted, I reached down and pulled the hem of my gown up myself, inching it higher and higher until my ass was nearly showing. I was certain that from his angle, he could see the edge of my black lace underwear.
I could feel his heart beating like a drum against my back. Slowly, tentatively, his fingers began to rub my bare thighs. His touch was light as a feather but burning like a brand. But that wasn't where I wanted his hands. I wanted him to slide them down and feel how incredibly wet I was for him. I wanted him to know the effect he had on his stepmother.
Taking the ultimate risk, I slid my own hand down, reaching beneath the fabric to pull my panties aside, exposing my bare, aching pussy to the cool air of the car. I moved my hand away, waiting with bated breath to see what he would do.
After a moment of agonizing hesitation, I felt his hand go down. I smiled to myself and parted my legs just a fraction more to give him full access.
"Ohh... Yesss..." I couldn't help but let out a low, muffled moan when I felt his finger on my bare pussy.
"Honey? Are you okay back there? Is everything alright?" Henry asked again, looking at us in the mirror.
My heart skipped in fear. He was watching us! I was expecting Randy to stop, but he didn't stop. He continued to rub my pussy with a slow, agonizing rhythm, his finger dipping into my wetness. He was totally lost in the moment, unaware that his father was watching us.
