*This is sort of a re-imagination of a story I read a long time ago. All characters are over the age of 18.
ROAD TRIP
My name is Bryan. This story takes place after my senior year in high school. It started off with my mom, Kasey (43 years old, pretty, dirty blonde hair), accidentally barging in on me as I was masturbating. Yeah, we've all been there at some point. Very embarrassing. Later in the day she pulled me aside and said "Look, all boys do it. It's ok, and nothing to be ashamed of. I want you to feel like that's something you can do, without judgement from me, alright?"
It was a liberating feeling. I stopped locking the bathroom door. I stopped waiting until the house was empty, etc. Once she caught me beating it on my bed. She walked in, saw what was happening, smiled, and turned around and left without saying a word.
Fast forward to June. I had graduated a few weeks earlier and we were taking a road trip across part of the country. We were packing up at our first hotel before hitting the road again, and mom went downstairs to check out. I had a few quiet moments to myself, so I pulled out my phone, loaded up some porn, and got to business. The door opened.
"Honey I forgot.... oh," she said, as she saw me on the bed with my hard cock in my hand. "I'll just be a minute," she said, evidently looking for something in the room.
"Mom! I'm sort of busy here!" I said, covering myself up.
"It's ok. Nothing I haven't seen before. Like I told you, it's nothing to be ashamed of."
She eventually found whatever it was and went back downstairs, so I resumed stroking. I finished quickly, still pretty worked up about having been caught like that. Or rather having been seen with my hard cock in my hand. It was exciting, and it gave me some ideas for the rest of the trip.
We were on the road shortly, and had a long day ahead of us. After lunch I lowered my seat back to take a nap. Being so young, I was fully recovered from the morning's "session", and was ready for round two. I sneakily began to rub myself over my shorts, until I was hard. Really hoping she wouldn't notice. But her eyes were on the road, so I continued rubbing my cock through the material of my shorts.
"Honey," she said. "Do you really think I can't see that?"
"Oh god, sorry mom," I spit out, covering myself with my hands.
"I know I said to not be embarrassed about that, but maybe don't do it when I'm sitting right next to you? Look, I'll stop up ahead at a gas station. I'll go inside and you can finish in the car."
She pulled over after a few miles and went inside. I made sure there weren't any people around, and then took my shorts down and resumed stroking myself to visions of Jennifer Lawrence. I had already cum earlier in the morning, so I had staying power. It was taking longer than I expected, and mom would be back any moment. I heard the car door open.
"Oh," she said, seeing what was happening in the passenger seat. "I thought I gave you enough time, I'm sorry. How about you move to the back seat and finish up?" she said, as she sat down in the driver's seat.
I crawled into the back and laid down, with my pants around my ankles. My head was behind the driver's side seat, so she couldn't see anything. The only sounds in the car were made by my hand pumping my cock. I then had a weird idea. I turned myself around, so that now I was laying the opposite direction. If she were to turn around, or look in the rear view mirror, she would have a direct line of sight to me abusing my hard cock.
"Almost done?" she asked, briefly turning around. She got a full look, and quickly turned back around facing the front. "If it's taking you too long, think about something that makes you.... you know."
"I am, mom," I replied, between pumps up and down my cock.
"What is it," she asked. Did my mom just ask me what I was fantasizing about?
"A teacher from last year. She was a MILF."
"Ok, that's good. Think about that."
"I'm kissing her and taking off her clothes."
"Great. Too much information, honey."
"I've got her bent over," I said, feeling the surge of cum coming now. Saying it out loud was just too hot. Seconds later I had blasted off all over my chest. I reached for the wet naps under the seat.
"All done?" she asked, before I hopped back in the front seat and we resumed our trip. This new policy on masturbation was fantastic. I loved it. Mom smiled and patted my leg. "Glad we got that out of the way. That's twice today, so I'm assuming you're all done until tomorrow?". No I was not, as she would be finding out later in the evening.
We reached our hotel at about 8 pm. We ordered room service and watched a movie. The room had one king size bed, and we were both laying on it at opposite ends. I was in just boxer shorts, and mom had changed into a robe, with her nightgown on underneath. It had been about 10 hours since my last ejaculation, so I was fully ready to go. I started rubbing myself through the fabric of my boxers.
"Mom?" I asked, leaning to my right towards where she was laying on the bed. "I'm starting to get super excited, and I want to jerk off again."
"Again?" she said, laughing. "That's okay honey, I'll just go into the bathroom and let you do your business."
"No you don't have to. You can stay right there. I won't be long." I slipped my throbbing cock through the hole in my shorts, and held it upright, slowly moving my hand up and down. Mom was trying to watch the movie still, but out of the corner of her eye she could see what I was doing. Finally she turned over on her side and faced me. "Almost done?".
"Getting there," I replied.
"What are you thinking about."
"The same teacher from before."
