Caitlin moped more than shopped. She would look at a dress she apparently liked and give a big sigh. "They have some nice black cocktail dresses. The one I brought is getting worn. I wish I had the money to buy a new one."
"I'll buy it."
"Come on, Thomas."
"I'm serious. Get a sexy one. You're my girl for the rest of the cruise. When we're dancing tonight, I want the other guys in the dance club to be envious."
"But..."
"And while we're shopping, let's get you some shoes with a decent heel."
Caitlin smiled. "Okay."
Caitlin's mood brightened considerably once she knew she was going to wind up with a dress and shoes. She tried on a few then we walked down to another store where she tried on some more. I enjoyed her modeling the different dresses for me. They all looked good on her and some made her look smoking hot. She eventually bought the one I liked best - a dress with a strap on only one shoulder and lots of lace holes in the top front so I could see most of her chest. It also clung tightly to the rest of her body and ended a little below her crotch area. She looked fantastic in it.
"How are you going to wear a bra with that?" I asked.
"Who says I'm going to wear a bra?" She gave me an evil grin.
Shopping for shoes wasn't nearly as interesting as I don't care about women's shoes.
"Are you going to get shitfaced tonight?" Caitlin asked me. We were in shoe store number two.
"Why would I do that?"
"Because you feel miserable over losing Rebecca."
"And how would getting shitfaced make things better? In college, I got shitfaced once. Puking my guts out afterward was probably the worst I have ever felt. I don't care to re-live that moment."
"Will you do me a big favor tonight and drink more when we're dancing than you're used to? I don't want to get drunk, but I want to get buzzed and it isn't fun drinking that much alone."
I thought for a minute. I wasn't much of a drinker and it didn't appeal to me.
"You told me to tell you anything I wanted you to do to make me happy," said Caitlin.
"Yeah, but did I say I would do it?" I smiled. "Seriously, as long as you promise to keep me from getting drunk, I'll do it."
"What type of drunk are you?"
"The I-wish-I-were-sober type."

"When did you know it was over between you and Rebecca?" We were in shoe store number four.
"When she didn't want to do the Full Rebecca Sunday night. We always did that. The Rebecca was the first more-than-friends thing we did together. If we had had a bad day, doing the Rebecca always seemed to make things right. For her to not want to do it told me she was pulling away. The next morning, it was a matter of watching her and confirming she had pulled away."
"What the hell is a Rebecca?"
"It's a long story. It's something we did at night. I don't want to discuss it."
"Okay. What do you think of these shoes?"
"They look like the last dozen you've tried on."
"Men!"

We had dinner in one of the main dining rooms. We sat with some people we didn't know and had a pleasant time. After dinner, we went to the early show. It was a musical I hadn't seen before and I enjoyed it a lot. After the show, we went drinking and dancing. Caitlin looked incredible in her new dress. I got a strawberry daiquiri when Caitlin did and I matched how quickly she drank hers. While we were dancing, a slow song came out. I didn't think it was appropriate to slow dance with my sister, so we went back to our drinks and took a long break. As we were talking, a guy our age walked up to us.
"Hey! I'm Tyler. You're brother and sister, right?"
"Yeah..." I said slowly.
"Then you don't mind if I dance with your sister, do you?"
"He might not mind," said Caitlin, "but I would. I don't dance with people I don't know."
"I liked to get to know you..."
"But I wouldn't. Go!"
We finished our drinks and went back out on the dance floor. We danced until another slow song came on, then we got some new drinks and talked. While we were waiting for a fast song, another guy tried to ask Caitlin to dance. She told him to buzz off equally as firmly.
"If you want to dance with somebody else," I said, "I understand completely."
"I don't want to. I don't want to have to worry about him slipping a roofie in my drink then using my body all night. Too much nasty shit has happened to friends of mine. At parties and bars, I stay with people I know and I tell them to not let some stranger try to take me home."
"Wow!"
"I try to not date a guy unless I've known him for at least six months and know one of his former girlfriends. Too many scary weirdos out there."
"Did you do that with Jacob?"
"No. See how well he turned out? We aren't sitting out slow dances anymore. I'm tired of getting hit on every time we do."
I had a great time dancing with Caitlin. As she had taught me how to dance, she danced how I wanted my partner to dance. The slow dances were awkward at first, but I got used to them. We kept a little space between us. Some couples close to us were groping each other.
At eleven, we left the dance club and went on the deck. We got some food, sat down and stared at the stars while the wind whipped through our hair.
"Are you going to dance my ass off tonight?" Caitlin asked me.
"I'm willing to keep trying. I'm going to hate the alarm clock in the morning."
"You're a much better dancer than Jacob."
"And you're a much better dancer than Rebecca. I'm sure her parents never let her go to a dance."
We made fun of the way they danced for a few minutes.
"Had you gambled with Jacob before?"
"We went to a charity casino night a month ago and had a great time. It was the first time either of us had done casino gambling."
"He seems to have caught the bug. He's obviously studied up on it." A random thought came to mind. "How is Lisa doing?"
"Okay. She doesn't like living with her parents but she doesn't make enough to live on her own."
"I'm sorry to hear it."
"When my lease is up, we might get a two-bedroom place together."
"Does she have any regrets about our summer together?"
"None. She had a great time and knew it was only for the summer. She told me you were hot in bed."
"Well, if I was, it was because I did all the things you told me to do. Three times with Jacob on Sunday? It sounds like you're an animal in the sack."
Caitlin flushed. "How was Rebecca?"
"In bed? Okay. She wasn't in the mood as often as I wanted. I don't think she was ever comfortable having sex. You know how fundamentalist kids are. Always the missionary position. When she was in the mood for sex, she would take her panties off right before getting into bed. If she left her panties on when she got into bed, there wasn't any way of convincing her to have sex. Lisa was more fun, but the only reason I dated Lisa was for the sex. With Rebecca, sex was more of the cherry on top."
"Earlier, you mentioned the Rebecca. What's that?"
"It's a long story."
"I'd like to hear it."
Oh, what the hell.
"The first time Rebecca and I slept together, we were just friends. We had watched a movie at my place on a Friday night and afterward we talked a long time about the movie. It was past midnight when Rebecca decided to go home and I told her not to, that only drunks would be driving so late. I asked her to sleep with me with the promise that we would both stay clothed and I wouldn't make a move on her."
"You slept together fully-clothed?"
"Well, Rebecca wore one of my T-shirts and panties while I wore a T-shirt and shorts."
"Why didn't one of you sleep on the couch?"
"I don't know. I wanted to sleep with her and she went along with it. We got in bed and I wanted to give her a hug. I somehow scooped her up and deposited her on the right side of my ch
est then hugged her there. I liked it and didn't want her to move off me, so I recounted our evening together; how much I had enjoyed hanging with her. At first, she had been uncomfortable but she gradually relaxed. When I was done, she asked if she could sleep on me and I said yes. The next morning, she told me she had loved the whole bedtime experience. The next Friday, she slept with me and asked me to tell her about our day again. So that became the Rebecca."
"And the Full Rebecca?"
"Well, the clothing steadily disappeared. My shorts got replaced by underwear. Then I left off my shirt. Then I bunched her shirt up high so I could feel her skin against mine. Then her shirt disappeared. Then my underwear disappeared. So we called our sleeping together with her in her panties and me naked the Full Rebecca."
"That's crazy. Or romantic. Or something. I can't imagine two adults dragging things out like you did. When I like a guy, we fuck on the first or second date."
I didn't respond as I was thinking about Rebecca. God, I missed her. I pictured her next to my bed wearing only her panties as she had on so many nights. Her long blond hair peeked out from behind her back. Her breasts jutted out proudly. Her soft skin was ready to slide against mine.
It was easy to push thoughts of her aside when Caitlin and I were doing stuff, but they never went away. Now I was surrounded by memories of good times Rebecca and I had had together. Loneliness engulfed me.
"Come on," said Caitlin as she pulled on my hand to get me out of my chair. "Let's dance some more."
"Sounds good."
* * *
It was two when we staggered back to the cabin. Caitlin went into the bathroom to do her bedtime stuff and when she came out I grabbed my shorts and did mine. When I came out, Caitlin was under the covers and I could see the top of her nightshirt. I got under the covers and lay down on my back.
I expected Caitlin to go right to sleep, but instead she said, "Thomas, the Full Rebecca sounds really neat. Could we do it tonight?"
"You're too big and heavy to sleep on me."
"I know, but I want to do the rest."
I stuck my arm out.
"Okay. Come put your head on my shoulder and I'll talk about our day."
Rather than move towards me, she did something under the covers. I took me a moment, but I realized she was taking off her night shirt.
"Caitlin, what are you doing?"
"Getting dressed for the Full Rebecca. Take your shorts off."
"Caitlin, what the hell? You're my sister. Put your shirt back on."
"Come on, Thomas. Just this once. I won't see anything and neither will you. I want to see how it feels."
I rolled me eyes. I loved to cuddle and cuddling with a mostly-naked woman would normally appeal to me, but it wasn't right with my sister. At the same time, it was what she wanted and there wasn't any harm. No one would find out about it.
"Oh, alright. Just this once."
"Now take your shorts off."
I slid my shorts off and was naked. Caitlin moved up next to me so her head was on my right shoulder. I pulled her close with my right arm and held her against me. I wondered briefly what panties she was wearing. I hadn't seen her naked tits, but I already had an excellent idea of what they looked like from seeing her in her bikini. I knew they were pressed into me, but I couldn't feel them distinctly. What I did feel was her soft skin covering the right side of my body.
"Okay, what did we do today?" I asked rhetorically. I recounted the boat ride, the hike through the jungle, and the exploration of the ruins. I talked briefly about our stay at the pool. I recalled the pleasures of shopping with her, seeing the show with her, dancing with her and having a late-night snack with her on deck. I finished with our final dance session and our doing the Rebecca.
"That was wonderful. Rebecca was stupid to give this up. We'll have to do this again tomorrow night."
"Caitlin," I growled. "You said just this once."
"I know, but I didn't know how great it would make me feel."
"You're taking advantage of my being a conflict avoider."
"I'm taking advantage of you being an awesome big brother who will do anything I ask to make me happy."
"You don't fight fair, Caitlin."
She gave me an evil laugh.
"Was Jacob good at cuddling?"
She snorted. "He was awful. After sex, he would say something nice and give me a kiss, then roll over, face away from me and go to sleep."
"I love to cuddle. Rebecca loved to be cuddled at home. When we were with friends or in public, all she would let me do is hold her hand. It really bugged me."
"Well, you don't have to worry about that anymore. There are lots of available girls who love being cuddled. Including me. I love you, Thomas." Caitlin gave me a long, sweet kiss on my check.
"I love you too."
"Good night."
"Good night."
Wednesday, Cayman Islands
My eyes felt glued together when the alarm went off. I fumbled over and turned it off. I then realized a problem with Caitlin's plan for us getting undressed for the Full Rebecca. How was one of us going to get out of bed without exposing ourselves to the other? One of us had to go to the bathroom so the other could get dressed for the day alone.
Caitlin of course solved the problem easily. She sat up so her body faced away from me, got out of bed, bent down to pick up her night shirt and put it on. I could only see her backside while she didn't have her night shirt on. What a nice backside it was. She was wearing pink, low-cut panties. I had some serious morning wood. I hadn't cum on the cruise and I was getting close to blue balls zone. I had occasionally thought about getting away from Caitlin for a while to beat off, but I had decided against it because I wanted every minute of the day to be good for her.
Today's excursion was a cruise out to the Stingray City Sandbar. Caitlin dug out her orange bikini and went off to the bathroom. I pulled on my swimsuit.
Unlike yesterday, we were relaxed and having fun with each other right away. The excursion was incredible. First, we went to a shallow reef and snorkeled in crystal clear water. The weather was perfect. We saw gobs of tropical fish. If we had stopped there, it would have been a really good excursion. Instead, we went to the Stingray City Sandbar. The stingrays were everywhere and had no fear of us. Both of us held one. It was amazing.
Once the excursion was over, we had lunch, worked out and showered. I showered first and tried to beat off while Caitlin was in the shower, but she came out before I was done. Once she came out, we took a nap. It seemed natural to sleep in one bed together. I was afraid Caitlin would want to do the Full Rebecca at nap time, but all she wanted to do was to hold hands.
Like yesterday, we did dinner, show, dancing and a midnight snack. As we sat and ate, I said, "When we were walking around the deck on the first day, you said you were looking to do four things on this cruise - excursions, drinking, dancing and fucking. I obviously can't do number four. How am I doing on the other three?"
"Great. I'm having a great time. I'm probably a poor substitute for Rebecca but you are more fun than Jacob. I was getting so tired of the drama."
"Anything you want to add to that list?"
Caitlin thought for a bit. "I enjoyed hanging out at the pool, but I don't want to be asked about Jacob so I'm fine with avoiding it. I'll stick with my initial list. How 'bout you? Are you having a good time with me?"
"You aren't Rebecca, but the things you want to do on a cruise are the things I want to do. I'm having a good time."
"Good." Caitlin paused for a bit. "Let me ask you something. When was the first time you slept with Rebecca?"
"Around Labor Day? I think the weekend before."
"And when was the first time you fucked?"
"Exactly a month ago." It seemed so long ago now. At the time, I thought it would be a date I'd always remember. Now, it was a date I wanted to forget. No, I'll remember the first time with Rebecca and forget Monday.
"It's hard for me to wrap my h
ead around how long it took you two to go from more-than-friends to lovers."
I shrugged. "Once or twice a week we took a step forward in our relationship, but the steps were so small that it took us a long time to reach the point of making love. It was all about getting Rebecca comfortable with the physical side of our relationship."
"I've made you talk about Rebecca long enough. Let's go dance some more."
* * *
Once again at two we staggered into our cabin. I felt a little silly putting my shorts on for bed, knowing I would take them right off. When I came out of the bathroom, Caitlin had her night shirt on.
"What is your shirt made of?" I asked.
"Silk. Feel it."
I did. "Feels nice."
"The girls like it," she said as she shook her tits. My cock stiffened.
I got into bed and stripped off my shorts. "Do you always wear a night shirt when you sleep with a guy?"
"Depends on the guy." Caitlin got under the covers and took off her night shirt. Again, I saw nothing. "If I am going to cuddle all night with a guy, I sleep naked or in panties. With someone like Jacob who wants to sleep by himself, I wear a night shirt."
I raised my arm and she put her head on my shoulder and snuggled up to me.
"Instead of doing the Rebecca, I want you tell me step by step how you got Rebecca to make love to you."
"Caitlin? Really?"
"Really. I'm just so curious. What were all the little steps?"
"I don't want to talk about Rebecca right now."
"Thomas, you promised."
I had promised. "Oh, okay," I said, feeling slight exasperated. "On one condition - if it starts making me sad, I stop."
"Agreed."
"So I'm starting with the first night we slept together...The next morning when we woke up, Rebecca gave me a kiss on my cheek and said thanks for the great night's sleep. That was our first kiss. She left right after we woke up to get dressed at her place. The next Friday, she slept with me at my place again."
