I went into my room and waited for Becky to be done in the shower. I stripped out of my wet swimsuit and put on a robe. The phone rang and I answered it. "Hey sexy!" said Sheryl's familiar voice. "Are we doing anything tonight?" "Hello beautiful." I replied. "I hadn't thought that far in advance. What did you have in mind? I've been at the beach this afternoon with Becky, and I'm fairly beat from the sun and water. Quiet night in?" "That's fine with me. What kind of quiet night in? I'd rather not hang out here, my brother has a couple friends over." She said. "No problem, I'm sure Becky and my parents would welcome you here. I think everyone here may be gearing up for a game night. How's that for a boring, quiet night in?" I laughed at myself. "You should come for dinner too." "Super. I'll be there by 7. What should I bring?" She was ever-thoughtful. "How about a bottle of wine? Your parents will give you one. My parents will drink one. And if you bring it, we'll all have some because they'll open a bottle too." I said. "Hey, how about I come early and the two of us cook dinner? I have some pretty good Chinese recipes I'd like to try." She suddenly interjected. "Sure. Come over whenever. I'll tell Becky, maybe she'll want to join us in the kitchen." With that settled we said our good-byes. I settled down into my desk chair as my computer booted and I reclined slightly. I did not think about what I was wearing, and my robe fell open, revealing my crotch completely. Of course, that was the moment Becky appeared at my door. "Uh, the shower's all yours." She said. I looked up at her, unaware of the state of my robe. She looked incredible. She was just wearing a towel, wrapped around her to hide all the important bits. Her hair was still wet, and hanging down around her face. The towel was not big and I could see most of her legs. After checking out her legs thoroughly I wondered why she was still standing there, so I looked up at her face. She was staring, and when I followed the line of her eyes I realized I was uncovered. "Oh crap!" I said, and quickly flipped my robe shut. "I'm sorry, didn't realize my robe opened! "That's okay." Replied Becky. "I've never seen one that wasn't hard and sticking up before. It is pretty different!" I was a bit embarrassed by this, and said, "well, I've been swimming, they shrink after being in the water..." Becky laughed and told me to take a shower. "Oh, Sheryl is coming for dinner, she and I are making dinner, want to join us in the kitchen?" I asked her. "Sure!" She replied. "Do mom and dad know?" "Nope. Just got off the phone with Sheryl. Haven't had a chance to tell them." I told her "I'll tell them, you go shower." And with that, she turn and disappeared from my room. I showered and dressed, making myself more than averagely presentable. When I got downstairs Sheryl was already in the kitchen with Becky. She had brought was seemed like an impossible amount of groceries for dinner. "Wow, did you bring enough food?" I asked. "Oh be quiet." Becky retorted. "This is going to be a long dinner with many courses. We'll eat while we play, your parents are picking the game. Now put on an apron, you're going to be chopping everything." I rolled my eyes and pulled on an apron. As I chopped, I watched the interaction between my girlfriend and my sister. I realized that my two best friends in the world were here in the kitchen with me. I didn't realize how attached I had become to Sheryl, I kind of figured that I was feeling close to her because of all the physical fooling around. I guess there was more than that, because I really felt a fondness for her that I couldn't explain, and I realized that we had actually been fooling around less in recent times, and just spending time together more. Dinner was a most pleasant affair. We took care of three bottles of wine and played a few games with my parents. It was approaching 10:00 when Becky said to Sheryl,
