I heard my parents car door slam. An overwhelming wave of panic started rushing in. Nancy and I jumped out of the hot tub and started collecting our swimsuits. I was able to quickly get my swimsuit back on, and get back into the tub. I assumed that Nancy would do the same, I was wrong. Nancy collected both pieces of her swimsuit, and her towel. She clinched the pieces to her body, wrapped the towel around herself, and rushed inside. Just like that, in an instant she was gone. I sat there in disbelief. What had we just done? The guilt came shortly after. I sat in the tub for what felt like an eternity. It probably ended up only being five minutes. I heard the back door open. It was our Mom, "I'm surprised to see you in here, you're not out on a Friday night?"
"I had nowhere to be," I responded quickly. "You guys are home early," I added.
"Your father started feeling a little under the weather, so we decided to call it an early night," my mother explained. I wondered how my mother or father did not see Nancy rushing to her room inside the house. Our stairs are right by the front door. My mother started telling me about their night out with their friends, but I couldn't focus. She wished me goodnight and retired back inside. Shortly after, I exited the tub, collected my towel, and retreated to the safety of my bedroom. As I was laying on my bed, the reality of my actions with Nancy started to settle in. I came inside my sister. Was she on the pill? Should we drive out to get Plan B? Is she okay? I needed to talk to her. She rushed out with out a word said. I knew I couldn't exactly go to her room at 11:00 PM and have a conversation with her. Not at least without running the risk of our parents overhearing. So I decided to send her a text message.
"Hey Nancy are you ok? Can we talk?" I sent the message with great concern of what was to follow. I waited patiently just staring at my phone. I hope she's okay. 30 minutes had gone by and I still hadn't received a response. I decided I was going to try and get some sleep, though I knew it would be impossible. I set my phone on the nightstand and flicked off my light in preparation for bed. Shortly after, I heard my phone vibrate. It was Nancy.
"Hi, yes I'm okay. What we just did was really reckless, we need to talk. Any chance you can come to my room?" Nancy asked.
I was surprised that she asked me to do this. She wanted me to go to her room now? How could we possibly pull off that conversation? What explanation would I give to my parents for going into my sisters room this late at night? "Your room is right across from mom and dads, they'll see me go in and maybe hear us talk," I responded. I thought to myself, this conversation is best done when we're alone. I waited in anticipation wondering what her plan was.
"We can wait until mom and dad are asleep, then you can come," she replied. I agreed. I knew I wasn't going to have any problems falling asleep before hand. I patiently waited for Nancy's cue to come to her room. Just before 1:00 AM I got another text from Nancy, "I think they're asleep, you can come to my room now." The nerves started to rush in again. I picked myself up off my bed and very quietly snuck through our upstairs hallway. This was terrifying. If I was seen at this time going into Nancy's room, I would have no good explanation. I successfully arrived at my sisters room door without being heard. I opened the door a little in hopes to see a signal or an invitation from Nancy to enter. Nancy was laying on the left side of her bed. She saw me at the door and waved me in. The light was off. The room was dark with the exception of the light coming off of her TV that was turned on. This gave me enough light to navigate my way through Nancy's room and over to her bed. I knelt on the floor at the side of the bed she was on. In that moment, I felt very unprepared for what was to follow.
"Listen Nancy, I am sorry for what happened. What we did was a mistake and we just got caught up in the moment. It won't happen again," I said this with concern, truthfully that's not what I wanted, but I thought that's what she wanted to hear in order to salvage any sort of relationship.
"Don't be sorry, you're not the only one to blame, it takes two. We got carried away," Nancy calmly responded to me. Her words and mood were comforting. She didn't seem upset about the situation. This was a relief to me. "You're right, we can't do that again. But you weren't too bad mister," she added with a smirk on her face. Nancy has an act for making me feel better. It was arousing to hear her say that. Thoughts of what we did in the tub flooded into my head and this started to get me excited. I dismissed those thoughts. I needed to focus.
"You weren't bad yourself," I retorted. I still needed to work out some of the questions that I had, "You let me cum inside of you, are you on the pill?"
"No I'm not, but I can try and go pick up Plan B in the morning if you want?" Nancy answered. I wonder what she meant by that. Why would she say "if I want?" I thought that was the only choice.
"That sounds good, I can pick it up if you want?" I used the same question right back at her.
"One of us can," she responded to me. I still felt like there was a lot of sexual tension in the air. Nancy was looking really good in her nightgown. The gown was cut low on her chest revealing a generous amount of cleavage. I wanted nothing more than to just fuck her again right there on her bed. I could feel myself starting to get hard again. My sister caught me looking longer than I should and drew a smile. I started to lean in closer to her at the side of her bed.
"I guess I should go back to my room now," I said to her in hopes that she would stop me.
"I guess you should," she responded. Just as I was about to get up, Nancy grabbed me by the shirt and pulled me in to kiss her. I responded by giving her light kisses on her lips. I could feel her soft lips sync with mine on each kiss. Nancy reached one of her hands behind my head for heavier kisses. At this point I was so overwhelmed with attraction to her. At the cue of her lips, I began exploring her mouth with my tongue. I could feel her lips part in response, allowing my tongue to enter her mouth. Our tongues violently began to dance around. I could hear some soft moans escape my sisters mouth. I was concerned that our parents would hear us. But at this point I felt like I couldn't stop. I got up on her bed, I began to lay on top of her. I continued kissing her passionately. I could feel my sisters free hand travel down my body towards my hard on. When her hand arrived, she started to grip my cock from the outside of my shorts. There was no stopping us. After a short while of kissing, I could feel my sister start to slip her hand through the waistband of my shorts to grab my bare cock.
I broke our kiss and whispered, "Nancy we shouldn't, mom and dad will hear us." My words had no weight to them. After a few seconds, our kissing resumed, and Nancy began to slowly stroke my cock. I could feel my cock starting to ooze with pre cum.
"Lay on your back," Nancy said pausing our kiss. In an instant, I got off of her and began laying on my back. My sister began to started to lower herself on my body. She grabbed onto the waistband of my shorts and pulled them off my body. This sprung my hard cock free. With her face inches away from my shaft, she looked at up at my eyes. She then fixed her eyes back on my hard cock. With her right hand she grabbed around my cock, and her tongue began trailing up and down the side of my shaft. This alone was almost enough to send me over the edge. My sister was very slow and sensual with her tongue. It felt electric. After a few moments, she began trailing her tongue around each of my balls.
