The highway stretched out like a black ribbon under the setting sun as we pulled out of the driveway. I was driving, my mom Karen in the passenger seat, her legs crossed in those tight denim shorts that rode up her thick thighs. At twenty-three I was supposed to be the responsible one on this trip to my cousin's wedding, but the way she kept shifting and sighing made my cock twitch from the start.
"Long drive ahead," she said, voice low. "You sure you're okay handling all the hours?"
"Yeah, Mom. I've got it." But my eyes kept drifting to the way her tank top clung to her heavy tits, nipples already poking through the thin fabric from the AC.
By the time we hit the first rest stop it was dark.

We grabbed food and got back on the road. Karen kicked off her sandals and propped her bare feet on the dash. "Feels good to relax," she murmured, rubbing her calf. "My back's killing me from sitting."
I reached over without thinking and squeezed her thigh. "Want me to pull over so you can stretch?"
She didn't answer right away. Instead her hand covered mine and slid it higher. "Or you could just keep driving and let me handle it."
Her fingers moved to my lap, tracing the outline of my dick through my jeans. I sucked in a breath. "Mom"
"Shh. We've got hours of nothing but road. Just drive."
She unzipped me right there, pulled my cock out, and wrapped her warm hand around it. Slow strokes at first, thumb circling the head every time she reached the top. I gripped the wheel tighter, trying to focus on the white lines while she worked me. Pre-cum leaked over her fingers and she used it to slick the shaft, jerking faster.
"Fuck, that feels good," I groaned.
"I can tell. You're throbbing." She leaned over the console, hair brushing my arm, and took the head into her mouth. Hot, wet suction. Her tongue flicked the underside while her hand pumped the base. I nearly swerved.
"Jesus, Mom, you're gonna make me come."
She pulled off with a wet pop. "Not yet. Pull over at the next exit. There's a motel."
We barely made it inside the room before she was on her knees again, this time taking me deeper. I fucked her mouth while she moaned around my cock, spit dripping down her chin onto her tits. When I pulled out she stood, stripped off her shorts and panties in one motion, and bent over the bed.
"Get in me," she ordered, spreading her ass cheeks. Her pussy was shaved smooth and already glistening. I slammed into her from behind, balls-deep on the first thrust. She was tight and hot, gripping me like she hadn't been fucked in years.
I pounded her hard, the sound of skin slapping skin filling the cheap room. She reached back and rubbed her clit, pushing back to meet every stroke. "Harder, baby. Fuck your mom like you mean it."
I grabbed her hips and gave it to her, the headboard slamming the wall. When she came she clenched around me, soaking my cock and the sheets. I pulled out and shot thick ropes across her ass and lower back, watching it drip down her crack.
We didn't stop there. After we cleaned up she rode me on the chair, tits bouncing in my face while she ground her clit against me. I sucked her nipples, biting just hard enough to make her gasp and come again. Later, in the shower, she bent forward and let me fuck her ass with soapy fingers first, then my cock, slow and deep until she begged me to fill her.
By morning we were back on the road, her hand resting on my thigh again, both of us knowing the return trip would be even longer.
