This is based on a real experience that I had, though I'll admit that I embellished some portions of the account.
A high school club I was involved in went on educational and recreational trips during the summer each year that we called "summer trips". There were only about 25 or 30 students allowed on each trip. Throughout the year students could earn points to gain a spot on the trip.
I went on three of these trips, and they were a blast. There was usually a pretty even mix of guys and girls, and most of us knew each other fairly well. We rode across some portion of the country on a school bus, seeing several sights and then camped at some state or national park at night.
The last trip I went on was when I was 18. There was one day on that trip while riding on the bus, where two 18 year-old girls that I was sort of friends with were sitting in front of me. Their names were Amy and Brittany. I'm not sure what they were talking about before, but they turned around and asked me a question.
"What do you think about our boobs?" Brittany, the more outgoing one, asked.
I was somewhat taken aback at their question. Even though I was constantly looking at girls boobs (I was a teenage boy), I never had a girl ask me to look at her boobs and evaluate them. I felt that I was up to the task, so I commenced checking out their racks.
Amy was probably about 5 feet 7 inches tall with a narrow frame and a very slim build. Her boobs did not seem to fit the rest of her body, because they looked rather large. Because of her narrow frame, her boobs were right next to each other, almost like they were pushed together all the time. It was a good look though, from my perspective, and I told her that they looked very nice and full.
Brittany was maybe 5 feet 2 inches tall, with a medium to wide frame with more rounded hips. She was definitely not fat, just shorter and curvier. Her boobs seemed pretty nice as well, though spaced wider apart on a wider frame, they looked less impressive. I told her that her boobs looked ample, but not as big as Amy's.
Brittany punched me playfully and Amy blushed. I was blushing too, and feeling pretty lucky to get the chance to look at their nice boobs, even clothed.
Then Brittany said, "We actually wear the same size bra, 34C. I do admit that Amy's bra is filled up more than mine. Actually, she is about to bust out and should probably move up to a D cup."
"What kind of boob description is ample anyway? What do you mean by that?" Brittany continued.
I told her without really thinking (again, the teenage boy), "Ample means good enough, sufficient, adequate."
"So Amy's boobs are very nice, and mine are just adequate, eh?" Brittany asked with raised eyebrows and a smirk.
She was teasing me, I knew, but I still got defensive, saying, "Yours are nice too. I mean I would be happy with them if I was with you."
Now I was really blushing, while Brittany smiled mischievously. "So you're saying that you wouldn't mind if these were the boobs that you got to stare at...or play with?" She said, with her hands cupping her own breasts.
My blush deepened even more if that was possible, spreading to my ears and neck, while my pulse quickened and I felt a twitch in my jeans.
Brittany laughed, still with mischief sparkling in her eyes as she turned back around to face forward in her seat. I could hear her and Amy whispering and giggling for the next few minutes, though I could not hear what they were discussing.
That evening we stopped off at some state or national park campground. Those details have not stuck with me as closely as the boob parts of the story. We set up our tents and got everything unpacked that needed to be. Once that was done, we had free time until the next morning.
I headed over to the shower area and got cleaned up. Then I was standing around talking with some of the guys in the group when Brittany and Amy walked up and joined our group. I noticed they too had just come from the showers. They had wet hair and different clothes: short athletic shorts and tank tops like girls sleep in sometimes. As I looked closer, I noticed that I could faintly see the outlines of their nipples. Neither of them appeared to be wearing a bra.
Despite the lack of support from a bra, Amy's boobs were still quite perky, sticking almost straight out. Brittany's drooped a tiny bit, but were still looking very nice. They talked with the group for a minute, then started heading off toward the tent they shared. Brittany leaned over and whispered in my ear as she walked by for me to wait five minutes and then come to their tent. She and Amy needed my help with something.
My mind began racing through the possibilities (and some fantasies too) of what the girls might want my help with. I couldn't help but think that it was related to it earlier discussion about boobs. I waited for what seemed like an hour, but was probably more like three minutes before excusing myself from the conversation.
I headed purposely off in the opposite direction from the girls tent, just in case any of the adult sponsors were watching. I circled back around and approached their tent. I could hear hushed conversation and giggling. I called out quietly and Brittany told me to come in and zip the tent behind me.
As I came inside I saw Amy and Brittany sitting close together in the middle of the tent. Amy smiled shyly at me, while Brittany, who was anything but shy, beckoned me over. I obeyed, zipping up the tent opening and walking to join them where they sat. I saw both girls checking me out as I approached. They smiled knowingly at each other, and I blushed at the attention. Brittany patted the sleeping bag between the two of them, and I sat down so that we formed a close triangular grouping.
We talked about the sights we saw that day, and they talked about some relational tension between a couple of other girls that I certainly had not picked up on. These girls were friendly and not unpleasant to talk with, but my mind was distracted. I was distracted by their proximity, their clean, slightly fruity smell, and of course their unencumbered boobs.
"What are you thinking about," Amy asked.
"Me?... I was listening to what you two were talking about," I stammered.
"And what else?" Brittany prompted.
I blushed and then said slowly, "What we talked about on the bus earlier."
