I gently parted her pussy lips and pressed the tip of my cock against her entrance. It was so wet, I knew it would slide right in with even a small nudge. I continued to massage her slit. While squeezing her boob with my other hand, just as I was about to give it a test, I suddenly felt Jessica’s body tighten against me. I looked over at her and her eyes were open and shocked.
“Charles, what are you doing??”
Instinctively, she clamped her legs shut, grabbed my arms and tried to get off. Unfortunately though, because of her forward motion, my cock which was already right at her entrance, slid easily into her pussy a couple inches.
“Ohh my God, what??” Her breathing was heavy. Luckily the music was loud and Lily couldn’t hear her sister.
“Jess, I’m so sorry…” but I could hardly focus on talking as it took everything in me not to thrust all the way in.
Jessica continued to struggle, but this only caused more motion and friction of my cock in her pussy.
I placed my hands on her smooth legs, and gently pushed them back open.
“Please Charles, you’re married to my sister… aren’t we family? What are you doing??”
“Jess, you’re so beautiful, I didn’t mean for this to happen. Please stop moving so much… you’re riling me up even more,” I said with strain in my voice.
“Charles!!” Jessica screamed. My penis flinched deeper into her pussy.
“Are you guys okay over there? Do you need me to turn the music down?” Lily loudly asked.
Jessica and I both froze. I squeezed her tightly against me, realizing now that both of her dress straps had fallen over her shoulders, exposing her tits. I looked at Jessica, lustfully, silently begging her not to say anything. Jessica looked at me, not knowing what to do. I was her brother-in-law after all; I’d watch her grow up, and now she looked at my one hand that was cupping her breast, and looked at my long penis halfway up her vagina. If she said anything at all, my marriage would be over – there would be no way out, and I think Jessica realized that too.
And so, after what seemed like an eternity, Jessica replied, “Sorry Lily, I was just having a dream and Charles woke me up.”
“Ah, okay. Charles, aren’t you tired? Why don’t you both get some sleep before our next stop?” Lily asked.
“Yea, just trying to get comfortable, I’m sure both of us will be able to get some rest soon,” I replied while looking at Jessica.
Jessica sobbed quietly as she looked around at her predicament. Her breathing was still heavy, and I could tell she was conflicted. She squeezed my arms and quietly whispered to me, “I’ve never had sex before. It’s so big, Charles, please don’t. We can still stop, right?”
I softly kissed the side of her neck, and whispered, “Jess, thank you for not saying anything. You’re so beautiful. Just let me push all the way in once, then I’ll pull out. Is that okay?” I could barely think straight, it was so hard to wait for a response, and it felt like I would explode at any motion.
Lily closed her eyes, and replied, “…Ok, fine Charles, but only because I love you like family. Please make it quick…”
