This trip took place during the summer when I was eighteen and David were nineteen before I left for college in late August.

As you might remember, the first time we had ever masturbated together was during Christmas break over a year earlier. At first, we did it together a lot, but then, after a few months, we settled into a routine of getting together two or three times a week. We would either go to his room or mine, but if the folks were out and not expected home for several hours, then we’d head to the living room like that first time. David and I had become much closer by the time we took this trip over a year later.

It was in mid-July when mom's best friend’s daughter had her baby. I was more excited about this family trip than I had been about one in a long time. It was almost like when we were children, practically best friends when we were together. However, I was not really expecting this trip to turn out quite the way it did for us.

David and I loaded the car for the folks and then headed down to where mom’s best friend lived. It was about a four to five hour drive. When we arrived, we checked into our hotel. We hadn't taken a trip where we stayed in a hotel since I was probably around eight or nine and back then we’d all usually get one room with two queen-sized beds, but since we were now much older, our parents decided we needed separate rooms; one for David, one for me, and one for them. The hotel must have been fairly full because our rooms were on a different floor than our parents. That evening we all met in the hotel’s dining room for dinner, after which mom and dad were going out to a nightclub for some drinks and an evening of partying and dancing.

We stayed at the hotel and David decided he wanted to go down to the pool. Naturally, I did too, so we changed into our swimming suits in his room, in front of each other, checking each other out the whole time as we always did. I knew then that this trip could get quite interesting very quickly.

The pool was much smaller than I thought it would be, but we were the only ones there at the time. I had just noticed that the water could have been a little bit cleaner when David pushed me right in. I fell into the pool with a huge splash as he stood next to the pool laughing before jumping in himself.

We were very flirtatious as we splashed around in the pool, our minimally clothed bodies rubbing against one another.

After a while, another family with small children showed up to swim, so we decided to get out and headed back up to our rooms.

When we got back upstairs into David’s room, I announced that I was going to take a shower. Keep in mind that David and I shared a bathroom back home, and after everything that had happened between us over the past eighteen months or so, we were relaxed about being in the bathroom together. It was a regular occurrence for one of us to be in the shower while the other came into pee, use the bathroom or brush their teeth. So I didn't think anything about David coming in after I got in the shower. What did surprise me though, was when he pulled back the shower curtain stark naked and stepped in to join me. This was a first for him!

“Well hello there, sweetie!” he said as he stepped in with me.

“Hello yourself!” I replied, in a voice obviously a little confused.

He said, “Well, I figured I might as well join you,” shrugging and grabbing a washcloth and the soap.

I turned my head and noticed that he already had a huge erection. I honestly didn't have any objections to him getting in the shower with me and I figured at this point, why not! At first, it was quite innocent. We washed our bodies and talked about going to see the new baby the next day, how things were going on back home and so on. So I turned my head back around started washing my hair. We came to a break in our conversation as I started to rinse my hair and I felt David press his fully erect cock up tightly between my butt cheeks.

Turning around very quickly, I shouted, “What the hell do you think you’re doing there?” We were now face-to-face, his hard cock pushing hard into my stomach. Neither of us said a word.

I slowly reached down to gently touch him. I had given him many a hand job by this time, but I had always taken my own sweet time, slowly feeling and exploring his cock as if I had never touched one before.

He reached around me and grabbed my butt cheeks with both hands, pulling me into himself hard so we were now pressed tightly, body to body.

Then something I would never have imagined happened. He kissed me. I have no idea if either one of us was more responsible for instigating this than the other, but neither of us seemed to object or stop doing it.

He then said in a trembling voice, “Let me get out of here. Be-e-e-fore I do something I’ll regret.”

I was worried that maybe he felt bad about having kissed me. I reached down turning off the water as he stepped out to dry off. I stood there in the shower and dried off too. I decided that he didn't feel bad about our kissing because before we were even finished drying off, he was again back playing with his still rock-hard cock and smiling at me. He left the bathroom first, getting onto one of the beds in his room. I followed suit but headed toward the other bed. Both of us were still naked.

“No, no,” he said, “Come and join me and sit down over here.” He patted on his bed for me to sit down next to him. So I did.

We started out by facing each other and touching ourselves at first as usual. Then David abruptly stopped and reached over for me to come closer. First gently grabbing and then squeezing my firm boobs, he then brushed his hands over my erect nipples making me moan with pleasure as his hands started to work their way down my torso, teasing my stomach and hips with his wandering hands down to my soaking wet pussy’s lips. He rubbed in my slit from my butt hole toward my clit, and as he reached there, he began a slight circular motion until I came with an extremely explosive orgasm.

We moved up the bed so I was sitting with my back against the headboard but we were still close and still facing each other. He again resumed working on my clit as I started slowly to stroke his rock-hard cock.

He knew what he was doing, expertly fingering me and hitting all the right spots. He was thrusting his hips along with my strokes and after only a few minutes he said, “Oh my god, I'm gonna cum, Pam!”

He then stopped fingering my pussy as he started to cum. His stream shot out further than I'd ever seen him squirt before, going everywhere. It was on the bed, headboard, wall behind me, as well as on me. There was even some on the floor.

After taking a second to recover he said, “Now it’s your turn.”

I said, “You take it from here,” and he had me lie back on the bed and he reached down to put one finger on my clit, rubbing it lightly using the same small circular motions before sliding one, then two fingers back inside my pussy pushing in then pulling out slowly before slowly building up speed. I was receiving one fantastic finger fucking from him.

“You’ll let me know when you're close, won’t you?” he asked. I nodded, not saying a word.

As his fingers worked away inside me, he leaned down and kissed me on my stomach, chest, and neck, making his way up to my mouth.

After a few more minutes I whispered, “I'm close. Oh yeah, David, so very, very close.”

Right as I felt my orgasm hitting, David pushed one finger up into my anus. Holy ‘s-h-i-t!’ He continued with two fingers deep in my pussy wildly as I came, grinding my hips into his hand making animalistic noises. I had never felt like this before. As I began to relax, after one tremendously wonderful orgasm, he slowly pulled his fingers out. We lay there silently, side-by-side, for quite a while, before regaining our breath and then talking about what had just happened between the two of us.

We both agreed that we wanted to do that again. Eventually, we got up and cleaned ourselves up. That night I did not return to my own room but instead stayed in there with David. We spent the night there, both of us still naked, locked in each other’s arms, just cuddling.

The next morning, we awoke and he hugged me tightly and then said, “Pamela, I really want you to know that last night I really wanted so desperately to just fuck you!”

I said, “I thought as much, but I’m so glad you didn’t go all the way with me since I’m not on the pill and it would be virtually impossible for us to explain to our folks that I’m pregnant by you, especially since I’m only eighteen.”

I knew right then that I had the most precious step-brother any girl could have ever had, and to this day I still do. I couldn’t have a real biological brother that was any better than David is to me.

We got up, cleaned up, dressed and met the folks down in the lobby. We went down to the restaurant for breakfast and then off to see the new baby.

I think that there may be more to this adventure …
