I got wet sitting on my friend's lap during a car ride

I'm 21 and last weekend I went on a crazy road trip with a group of friends, all crammed into a van for a seven-hour drive to a music festival. The van was packed tightly, and since I'm the smallest, I ended up on my friend's lap in the middle row. Let's call him Ethan, a guy with a lean build and a mischievous smile that I've always found sexy, even though we never did anything about it. It was late, and the van rumbled over the mountain roads, the only sounds the hum of the engine and the quiet chatter of the driver and passenger in the front. Most of our friends were asleep or had turned off, leaving Ethan and me in our own little bubble.

Ethan's arms wrapped around my waist to steady me as the van rocked. I was wearing thin yoga pants, and every jolt caused his cock to press against my pussy through the material. At first I tried to focus on staying still, one hand on the doorknob above my head and the other on the seat in front of me. But the constant movement, plus the heat from Ethan's body, made my pussy wet. My clit throbbed with each stroke, and I couldn't ignore how fucking good it felt.

I don't know what got into me, but I spread my thighs a little, pressing my pussy harder against Ethan's crotch. I could feel his cock getting hard, thick and stiff beneath me, and it sent a shiver through my body. My yoga pants were so thin there was nothing between us. I looked back and Ethan's eyes met mine, a hungry gaze in them. He knew what I was doing. His hands moved to my hips, pulling me in harder, so every rocking of the van drove his cock into my pussy. The friction was crazy. His hard cock rubbed against my clit with every turn, my pussy getting wetter and wetter, soaking my panties. I bit my lip to keep from moaning, my tits heaving as I tried to stay quiet. Ethan's fingers gripped my hips, guiding me, and I heard his low groan as the van hit a sharp turn. I rocked my hips slightly, matching the rhythm of the road, chasing that sweet pressure on my clit. His cock slid through my clothes and into my pussy, driving me wild.

My body burned, my pussy throbbing with need. Ethan squeezed harder, pushing me further, and I knew he was just as turned on. The van had hit a rough patch, and that was it—I came hard, my pussy clenching as waves of pleasure ripped through me. I held my breath, collapsing against Ethan's chest, shaking. He held me close, his breath hot in my ear as he whispered, "Fuck, you're going to kill me." Exhausted, I melted into him, slumping in his arms, his cock still hard beneath me.
