Chapter 9: Need More

The first half mile or so, it wasn’t hard to walk in silence. I was content reliving my first time having sex with my sister. I pondered things like: I put my dick in, then pulled it out, then put it back in again. Did that mean I had sex with Tanya twice, or did it not count because I had only cum the one time? However, after about 10 minutes on the trail, I was getting horny again, and I wanted nothing more than to touch, kiss, and even fuck Tanya again. And that was even with Tanya putting her sports bra back on and throwing the tiny crop top back into her backpack. I could understand why she was freaking out, but all I wanted to do was fool around with her some more. Now that I knew what magnificent tits were hidden under the tight sports bra, Tanya just looked different to me, sexier even when not showing off. However, I didn’t want to make my sister uncomfortable by talking about things she didn’t want to talk about, so we walked without saying anything to each other. Still, the rest of the trip downhill became filled with uncomfortable silence. It made for a long three miles, and even though gravity was working with us, we didn’t make nearly the time we had heading up the trail. We must have been getting close to the point where our trail rejoined the main one back to camp because I noticed a fragment of conversation on the wind. It was then that Tanya surprised me, “Turn around.”

“What?”

“Turn around; go back up the trail.”

“Why?” Tanya didn’t answer directly. Instead, she stepped close to me, grabbing my crotch with one hand, “Turn around and go back up the trail.” My cock hardened pretty quickly in my shorts, and I just said, “Oh!” and started walking. I didn’t say anything immediately but soon asked, “So what changed your mind?”

“I blame you for this. The more I walk with your cream inside me, the more I want a second helping. For the first half mile, I was really angry with you for starting this whole mess off by asking to touch my boobs. But then you actually listened to me and stopped talking about what happened. That made me angry at myself for letting things get crazier and crazier. Then that faded to annoyance that my brother had popped my cherry, and that faded to indifference as I considered that no one else would ever know, so what did it matter? Then my pussy started to feel tingly, and I began to think maybe it wouldn’t hurt to get one more dose of your cum. I’ve spent the last mile getting hornier and hornier thinking about letting you dump another load of jizz inside me!” My cock had softened a bit since Tanya grabbed my crotch, but after hearing those words, it surged with a vengeance. When I looked at Tanya, her eyes were half closed, and her face looked similar to when we had been making out. “I mean, seriously, Mike, what have you done to me? At the top of the trail, I was sure it was a one time experiment with incest. Now down here at the bottom, I’m not sure I could make it through dinner without another dose of brotherly love before we get back to camp!” I swept Tanya up in my arms, and she let me kiss her. However, when I started trying to get her out of her clothes, she protested. “Not here; let’s get over to that tree off the trail.” It was a scraggly thing with sparse leaves, but we both raced for it. Tanya reached the tree first and bent over at the waist, bracing herself against the tree with both hands. I came up behind Tanya, and this time when I tried to unsnap her shorts, she just made happy noises. I pulled off both shorts and panties, and she wiggled her hips to allow them to fall to her ankles. Then she stepped out of them and spread her legs invitingly. I undid my fly and fished out my hard cock. Fully able to see what I was doing, I tried rubbing my cock on the outside of Tanya’s pussy again. “Mike, what are you doing? Trying to make me go insane? I need you inside of me!” She said while shifting her hips uncomfortably. Still, I didn’t try to penetrate Tanya just yet. I was still nervous about how quickly Tanya’s pussy had made me cum earlier, and I was trying to really rile her up before I put my dick back inside her. However, once again, I slipped inside my sister without meaning to. Her pussy seemed to have some magic quality that could pull my cock into it even when I was trying to keep my dick on the outside. This time, knowing Tanya was on the pill, I didn’t try to pull out, but instead got an even better grip on my sister’s tiny waist and tugged on her hips. “Fuck Tanya, that feels so good!”
