Until somewhat recently, my only experience with nudism was on my graduation trip to Spain with my mom and older sister. One of our stops was at a town on the coast where we spent a few days relaxing on the beach.
Before we left on the trip, my mom suggested that I might be more comfortable in a "bikini" style swimsuit, like the ones I had worn when I was younger. She told me that "all the European men liked to wear them". It didn't take much convincing. I'd mostly given them up due to peer pressure, and the idea of wearing one again seemed like fun.
Our first day at the coast, I donned my bikini and spent the day sunning and swimming with my mom and sister. Being 18, I couldn't help but notice that a few of the women were topless. When my mom joined them, I tried not to act too surprised. We weren't really open about that sort of thing at home, but we were on vacation and the rules seemed different.
We went back to the hotel to shower and change for dinner. I got another shock when my mom, who'd taken the first shower, entered the bedroom we were sharing with nothing but a towel around her head. She hung her bikini near the window to dry and suggested we rinse out our own suits and do the same. My sister and I exchanged a shocked look.
Our mom playfully chided us for being so modest. My sister took the next shower and returned wrapped in a towel. I used the bathroom after her. They were both dressed by the time I'd finished. Normally I would have changed in the bathroom. I'm not sure what compelled me, but I decided instead to change in the bedroom. Facing away from them, I removed the towel and pulled on my briefs. Then I finished getting dressed and we went out for dinner.
We came back late and got ready for bed. The room wasn't air conditioned and it was hot and humid. As my sister and I changed into our bed clothes, our mom declared that it was too hot to wear anything to bed. She acted casual as she removed her clothes and slipped into the bed that she and my sister were sharing. My sister and I exchanged another glance, but tried to act normal as we got into bed.
I laid awake for a while trying to sleep, but I uncomfortable and sticky with sweat. After deciding that my mom and sister were probably asleep, I quietly took off my clothes and tossed them over near my bag.
My mom was up first the next morning. She showered, then woke us up. My sister took the bathroom next. I remained in bed, realizing that I didn't have a way to the bathroom without exposing myself. My mom nagged me that it was time to get going. When my sister was done with her shower, my mom told me to get moving again.
I waited until they seemed occupied, then got out of bed and walked to the bathroom. For a second, I thought I'd go unnoticed. But, as I crossed the room, my mom turned around and took in my nude form. To make matters worse, I was fully erect as was often the case in the morning. She said nothing, but I did see her crack a smile.
I took my shower. I had thought I'd feel embarrassed, but I felt almost nice about the brief experience. Once again, I returned to the bedroom wrapped in a towel. Like the previous night, they were ready to go. This time, however, I tossed my towel on the bed and took my time getting dressed while facing them.
We had a brief breakfast, then made our way to the beach. My mom removed her top almost immediately. When the sun started to set, we returned to the hotel. My mom got cleaned up and walked out naked. Following our routine, my sister went next. She came out wrapped in a towel and hung her bikini next to our mom's. I went last. This time I dried off and put my towel back on the rack. Then I returned to the bedroom to hang up my suit. We discussed the dinner plan while I got dressed.
That night, our mom got naked as we readied ourselves for bed. My sister, who usually wore shorts and a tank top to bed, decided to forgo the shorts and go to bed in her panties and top. Following our mom's lead, I stripped of my clothes and got into bed.
The next morning, I woke up early. I got up to go to the bathroom. It was just starting to get light outside, and I could see that my mom had pushed down the covers exposing herself and my sister during the night. I went to the bathroom and then returned to bed. I tried to sleep for a little while, but I couldn't stop looking at the bed across from mine.
They woke up a little less than an hour later. My sister and I stayed in bed while our mom used the bathroom. When she'd finished, my sister took the next turn. I sat up and chatted with my mom as she got dressed. I don't know what compelled me, but as we talked I slowly pushed the covers down and eventually kicked them off. I was erect again, although this time it was more from excitement than the usual morning reaction.
My sister came out wrapped in a towel. She paused, staring at me briefly, before telling me it was my turn. I stepped out of bed. As I walked to the bathroom, my sister turned away and removed her towel. I almost stopped, but continued past as she started getting dressed. I took a shower and dressed in front of them as I had the previous morning.
That afternoon, my sister joined my mom topless on the beach. We stayed on the beach the whole day, finally returning to our hotel to get ready for dinner. Our mom went first as usual. She didn't bother to close the door. We waited, but when she was nearly finished I took off my bikini and rinsed it out in the sink.
She finished her shower and got out just as I was turning off the sink. I told my sister she could go next. My mom said she'd rinse out my sister's suit. My sister hesitated, but removed her swimsuit and handed it to my mom as she got in the shower. My mom took my suit and hung them together near the window. I stood in the middle of the room, naked, as I waited for my turn.
As she arranged the swimsuits, she commented that she was glad I'd opted to wear a bikini on the trip and that she'd always thought I'd looked cute in them. She went on to say that she'd wished we'd been more open at home and that she felt like she'd missed out a little now that I was starting college. I agreed that it felt nice and that we still had a few months left to make up for lost time. My sister didn't bother to cover herself after her shower. I went next and we finally all got dressed and went out for dinner.
That night, we removed our clothes before getting ready for bed. The three of us did our nightly routine in the nude. I didn't bother with the covers when I got into bed. My mom and sister didn't either.
There hadn't been much opportunity for privacy on the trip and it had been more than a week since I'd been able to relieve my sexual tension. That night, I had an amazing dream about the girl I'd had a crush on at school. It had been a few years since I'd had a wet dream, but I knew I'd just had one as I woke up from the fantasy. When I opened my eyes, my mom was standing next to my bed.
I was on my back. She was naked except for the towel on her head. I'll never forget what she said: "Must've been a good dream." I laid there feeling a mixture of embarrassment and excitement. "I'll get you a towel," she said. She got a wash cloth from the bathroom and brought it to me. I cleaned myself up. That morning, I took the next shower and my sister went last.
It was our last day there. At breakfast, our mom said she'd heard about a little beach nearby that was popular with the locals. She asked if we wanted to check it out. When we said sure, she said there was one catch. It was a nude beach. Although we'd opened up around each other, being in public felt different. So, I was surprised when my sister said she was game. Not wanting to be the odd one out, I agreed.
We had to walk about half an hour to the beach. It was mostly deserted when we got there. We found a space to ourselves and laid our our towels. Our mom took the initiative, removing her clothes and bikini. My sister, almost without hesitation, did the same only stopping briefly before removing her bikini bottoms. I undressed to my swim briefs. I remember looking around wondering what would happen if someone we knew saw us before sliding them to the ground and putting them with the rest of my clothes.
At first, I remember feeling awkward. To make matters worse, I immediately became erect. Fortunately, no one was too close to us, so it wasn't obvious. My sister and I tried to act casual. Our mom took out the sunscreen and said we'd better make sure not to get burned. She started applying it to herself. We had to stand up to join her.
The three of us rubbed the lotion into our bodies. I tried to face away from the main crowd on the beach. When I got to my legs, my mom reminded me not to miss anything. I knew what she meant and tried to get the sunscreen onto my erection as quickly as possible. She helped my sister with her back, then offered to do mine.
I turned away from her and she stared rubbing the sunscreen into my back. When she got to my low back, she put on a little to much. She said she'd rub it in and proceeded to apply the screen to my ass and legs, which did nothing to help my erection subside.
Finally ready, we laid out on the beach. After a while, my mom suggested we swim. My sister and I were nervous, but followed. I was still rock hard as we went down to the water, but was glad to have a way of concealing it as we walked into the ocean. We swam around together, and I had to admit that it felt amazing. My nervousness started to wash away and my erection went with it. We spent the rest of the day alternating between sunning and swimming. Toward the end of the day, my mom even convinced us to let her take a bunch of pictures of me and my sister and got someone to take a few of us together.
We reluctantly headed back to the hotel at the end of the day. We showered and went out to eat. Then we returned to the hotel for our last night in the town and drifted off to sleep naked in our beds.
We had a train to catch to our next destination that morning, so we had a quick breakfast and went to the station. Our next hotel was nicer and air conditioned. My sister and I waited awkwardly after we'd gotten ready for bed the next night. Our mom, probably sensing what we were thinking, walked over to the air conditioner and turned it off. "I don't think we'll need this," she said as she cracked open the window. We removed our clothes and made our way into bed. We continued that way for the rest of our trip.
No one was really sure how to act when we got home. Our return flight arrived in the afternoon, so we occupied ourselves until it was time for bed. We all had our own rooms, so we went our separate ways. I slept nude, but without company that night.
The next morning, I got up and went to the bathroom. My sister and I shared one between our rooms. I considered going naked, but something made me put on some clothes. My sister was already in there in her usual shorts and a tank top.
We went down to breakfast. Everyone was quiet. My mom joked that we must all be in a post vacation funk as she set out our plates. We reminisced about the trip and how much fun we'd had travelling. We all talked excitedly about going to the nude beach, which had been a mid way through the trip. After breakfast, my sister and I cleaned up the kitchen.
"You two have any plans today?" we heard our mom as from behind us as we did the dishes. We both replied that we did not. "How about a little beach vacation at home?" she asked. We turned around. She was standing over by the table completely naked. My sister and I emphatically said yes, and quickly finished the dishes. We returned to our rooms, shed our clothes, and joined our mom out back to enjoy the sun.
The rest of the summer, we were naked almost any time we were home.
