It felt like Mom didn’t want to wait for the next wave. Was that possible? I didn’t know. All I knew was, my dick was now hard as a rock. There is no way Mom didn’t feel it. My shaft was placed right between her cheeks.
Very thin swimming trunks and Mom’s bikini panties were the only things between my hard dick and her pussy. I looked around. Nobody noticed anything.
Most of the people on the boat were facing away from us. Pretty much everybody was looking out onto the ocean. I saw some lips move, but I couldn’t hear what they were saying. Nobody looked in our direction. Plus, our heads were at the same level as everybody else's groins. Nobody could really see us.
And I don't think anybody would have noticed anything, even if they were looking in our direction. We didn't really move. Our upper bodies remained pretty still during all of this. They only parts of our bodies that moved, were our hips.
I was so ashamed and at the same time, turned on. Mom was basically dry humping me. I didn't know if she really pushed down, but it didn't matter. It felt absolutely amazing, having my dick massaged by her ass cheeks.
She was sliding up and down. And with every wave, her pelvis was pushed onto my hard dick. And since it was detained by my swimming shorts, it slid between Mom's legs, poking her. Mom must have felt my dick between her cheeks, on her pussy and between her legs. She didn't say anything. She just looked out of the boat.
The pleasure was overwhelming. I thought I might cum soon. I tried not to gasp. I didn't want to make any noise. Mom's ass was sliding down my shaft and I thought I couldn't hold back any longer. But then all of a sudden, the boat slowed down. I looked up, and saw the beach approach.
I was so fucking relieved. But now I had a new problem. I had a raging hard on. How could I possibly get off the boat? I had no idea. I panicked.
And then the boat had reached its place at the dock and stopped. I saw that some people were already moving, getting off the boat. I had to think. But then all of a sudden Mom, without standing up, or turning around, said:
"Could you take the beach towels, honey. The bag is too heavy for me."
I mumbled something which sounded like: "Yeah."
And then more and more people got off the boat and Mom finally stood up. Slowly. She didn't turn around. And while she stood up, I took the beach towels and placed them on my lap to hide my erection.
I put on my knee immobilizer and somehow, while waiting for everybody to get off the boat, my dick got limp again. As soon as everybody got off the boat, Mom took my elbow and helped me to get off the boat as well. It was a strange feeling to feel her fingers on me, after what just happened.
Mom didn't say anything. We just quietly followed all the other people. And then we saw the beach. It looked amazing. The water was bluish-green and the sand was almost white.
It looked beautiful. Mom and I walked on the beach for a while, to find a nice spot for us and then we put our beach towels down on the sand and lay down.
We didn"t do much, the entire day. We just enjoyed the sun and the view. Mom spent most of her day reading a book, while I was listening to music on my ipod. From time to time we cooled off in the ocean. The water was absolutely perfect. But I couldn't really relax.
I thought about the ride on the boat. I knew it was sick to get a hard on with your mother on your lap. But it felt too good to be true. My dick didn't care who it was giving him the lap dance. But I did. Mom must think that I'm sick.
I was so embarrassed. And what was even worse: we had to get back on the boat again. Oh god, I hoped that Mom wouldn't sit on my lap again. I couldn't think about anything else the entire day.
Plus, I was so close to an orgasm that morning, that I was extremely horny the entire day. I needed another dip in the ocean to cool off.
At some point Mom got us sandwiches from the beach bar, that was located right there at the edge of the beach.
"Here you go honey."
"Thanks."
"You were right... It is really beautiful here."
"Too bad Dad couldn't come. I hope he's alright."
Mom didn't respond. All she said was:
"Just enjoy your day. It's your birthday surprise. We wanna make you happy."
She didn't really look at me. And I couldn't look at her either. So we just lay on the beach next to each other the entire afternoon. On the evening Mom went into a changing booth. She came out wearing a white tank top and a pair of pink, wide hot pants.
After that, we went to the beach bar to have dinner. After we finished, we headed back to the dock. The guy told me we had to be the first ones there, so we got there early.
Again, Mom helped me to get on the boat and to the seat I had in the morning. I sat down and took off my knee immobilizer. Mom placed the beach bag next to me and remained standing. She didn't sit down.
I was relieved. Or was I? The entire day I hoped that Mom wouldn't sit on my lap again. But now... as I was sitting there again, horny as I was, I was wishing she would sit down on my lap again. But she didn't.
By the time we got to the boat, it was already getting dark. And while we were waiting for everybody to get on board, it got darker and darker. Everybody seemed to be really tired from their day in the sun, because I saw nobody talking or anything. Everybody moved very slowly.
But about twenty minutes later, everybody was back on the boat. This time, Mom was standing next to two other women. The unattractive guy with the beer belly was nowhere to be seen. So I guess this time nobody would hit Mom in the back. I realized that Mom wasn't going to sit down this time.
When the engine started, the noise seemed even louder than this morning. And then the boat slowly started to move away from the dock. As before, everybody was facing to the inside of the boat, with their heads turned, looking out onto the ocean.
And then slowly, the dock disappeared and with it, the light of the bulb, which was mounted on the dock. And soon we were surrounded by darkness. We did see the dark waves and the lights coming from the shore, but on the inside of the boat, it was pretty dark.
Like everybody else, I was pretty tired. I thought about closing my eyes, but then I saw that Mom was moving.
"I have to sit down again, okay?"
I didn't know what to say.
"Yeah, sure."
I quickly rolled up the legs of my bathing shorts. I thought, if there was more material between Mom and me, I wouldn't feel all that much. And then I leaned back.
Mom slightly turned and then sat down on my lap. Nobody around us cared. And then Mom took off her huge sun hat, it was dark, so she didn't need it anymore, and put it down on her lap.
And then, the boat picked up speed.
That morning, almost fifteen minutes passed until Mom sat down on my lap. This time, it didn't even take two minutes. So we pretty much had the entire ride ahead of us.
And this time, it was even harder to think about anything else. It was so dark, that I couldn't watch the other people. There was only one thing I could concentrate on: Mom's ass on my lap. And what can I say... I was horny all day... it was completely dark out... and I had all day to think about what happened that morning... so within three minutes, my dick got hard. The rhythm of the boat hitting the waves started, and with it, the bump and grind. Mom's ass cheeks were doing a great job massaging my dick. I knew Mom felt it already. But she didn't say anything.
And then there was another problem: with every time Mom and my pelvis left the seat and gravity pulled us back down, Mom's ass slid the legs of my trunks higher up. And then, another push later, I realized that my dick was freed from the inner part of my swimming trunks and was now about to poke out.
And then it happened. The tip of my penis made contact with Mom's leg. No material was between the two.
I felt Mom freeze. But she couldn't. There was nothing we could do. The boat rocked us back and forth. So with the next wave, my dick poked out of my trunks even more, sliding along Mom's thigh.
It felt electrifying. I felt pre-cum ooze out of my dick. And with the next wave, I felt that Mom's thigh was moist from my pre-cum. Which made it much easier for my hard dick to slide up and down Mom's leg. Not only did it make it easier, but it made it even more pleasurable as well.
Of course Mom felt it. All of a sudden she had a moist thigh. But still, she didn't say anything. She kept still. Actually... she didn't keep still. So far, the waves were responsible for all the movements. They pulled us up and slammed Mom down on my dick. But then I saw Mom adjusting the sun hat a little bit. She slid it a little more to the side where all the other passengers were. And then I felt her hips move. Not up and down, but she moved forward and then backwards. Which had the effect that my dick wasn't slammed into her thigh, but it slid back and forth between her legs.
