I had a long weekend with my wife, her mother and her aunt Becky in a rented camper van on the beach. Since the camper had surfboards on board, we naturally wanted to use them. Unfortunately, none of us had any experience with them and had never stood on a board before. Luckily, it was fairly calm and there were hardly any waves. So I went out of the water with the board one after the other with the ladies. My wife was the first to try kneeling on the board. I kept the balance of the board, but after half an hour my wife gave up and went back. Then my mother-in-law wanted to try it. Again we went out on the water with the board. The water level was quite low on the bank, so I could always walk alongside and the water was only 1.50 meters deep at 300 meters. She did well and was able to stay on the board longer than my wife, but she often tipped into the water and I had to keep helping her climb onto the board. This worked best from behind, so that I stood behind her and she pulled herself up, and I could hold the board from behind.

There was always light physical contact under the water, of course. When I pulled her up, she leaned forward and pushed her backside towards me. Since my arms were just long enough to hold the board, the contact was intense. But she was skilled at pulling herself up onto the board quickly. Since it was strenuous for her, she wanted to go back after 30 minutes.

Now Aunt Becky wanted to try it too, of course. So back onto the water and 300 meters out again. I showed her the same procedure, but she fell sideways into the water very often. Again and again she got back onto the board from behind. Of course, with the same physical contact. Now she said I should stand in front of the board and hold on when she wanted to get on from behind. It worked well, but after a few times she crawled forwards from behind to me and then sat with her legs apart with the board between her thighs. My eyes remained fixed on her pussy, which was clearly visible under her swimsuit.
She repeated it a few times and then said that she was getting a bit exhausted and that I should help her from behind by pushing her buttocks up.
So I helped her up from behind. She was wearing a thin swimsuit and I felt her skin on her buttocks in my hands and imagined the view from the front again. Then, despite the cold water, I felt feelings in my penis.
Then she wanted to go back to the beach too, lay down on the board and I pushed her. When the water was no longer so deep and my swimming trunks were visible, she discovered my erection. Of course I was embarrassed because there was a very clear bulge. We carried the board back together and I walked sideways so that the bulge wasn't noticed by anyone else. She then asked me if it was her fault!! She probably saw it on my face that I confirmed it.
The next day we were at the beach again but today only Becky wanted to get on the board. Of course I noticed straight away that she was wearing a different one-piece. When we were outside again and her swimsuit was wet I saw that her nipples were clearly visible. Her pussy was also much more clearly visible now because the inner material was probably much thinner.
We did the same exercises as the day before and today it didn't take very long until I felt an erection. Since I wanted to get rid of it now, I pushed my penis out of my swimming trunks to the side so I could jerk off and relax. When she was sitting on the board with her legs spread again and I could see her pussy from the front, it was almost time. But she fell sideways into the water again and wanted to get off from behind again and I was supposed to hold the board from behind again. Now she walked past me from the side and noticed what was sticking out of my swimming trunks. Without saying anything, I felt her hand grabbing it and jerking me off.
