Chapter 4: Making Out

The trail grew steeper still, and my desire to kiss Tanya certainly helped keep me moving. This isn’t to say that I moved uphill without resting and encouraged Tanya to do the same. We both stopped to rest a few times and took a swig of water from our canteens. By the time we saw the three mile marker, we were both dripping with sweat and a little bit out of breath. In shape or not, this was a strenuous trail, and we weren’t taking it easy. I stepped closer to Tanya, wanting to claim my kiss, but she held a hand up to keep me away, saying, “Wipe your face off; I don’t want you dripping sweat on me.” As I toweled my face off with my shirt, I responded, “What about you? You’re sweating as much as I am.”

“Well, you seem to think it’s sexy, or at least not gross.” I actually did think it was sexy. The beads of sweat on Tanya’s face were cute, and the ones dripping from her big boobs made me ache with desire for my sister. On top of that, her shirt was clinging to her chest, and I could see more underboob than I had even when Tanya lifted her arms over her head. I almost jumped to Tanya when she motioned that I could approach for the promised kiss. Mindful of Tanya’s stipulation that I couldn’t touch her chest while kissing her, I put one hand on the small of her back and the other behind her neck as I slowly dipped her body and moved my face closer to hers. Despite the thought I had a mile back when Tanya had agreed to let me kiss her, I was approaching this kiss very gingerly. I didn’t do anything to try for a long, drawn out kiss, either. Actually, as our faces got closer and closer, I just barely touched my lips to Tanya’s and then pulled back to look at my sister.

“Dude! That kiss sucked!” Tanya scolded me. “How do you ever expect to get a second date if you kiss like that? Try this!” My little sister grabbed my face with both hands and pulled it back down to hers. Then my brain almost exploded as I felt her tongue enter my mouth. Now I was French kissing my sister, and I had no idea what I was supposed to be doing. At first, I tried to keep my tongue out of her way so she could put hers wherever she wanted. She seemed to be pulling my face more intensely to hers, and her tongue seemed to be seeking mine out, so I stopped trying to evade hers. At some point, instinct kicked in, and I started moving my tongue, not to evade hers but somehow complement what she was doing. That finally seemed to make Tanya happy because she relaxed in my arms as our tongues dueled. When the kiss finally ended, Tanya stated, “You finally started catching on at the end. Please tell me you don’t kiss your dates the way you kissed me at first.” When I didn’t answer immediately, Tanya continued, “Aw fuck! Your first kiss ever was with me, wasn’t it? Damn it! I can’t believe I’m saying this, but you need more practice kissing. I can’t have my big brother blow a bunch of dates because he doesn’t know how to kiss a girl.” My brain was still trying to process my good luck when I felt Tanya’s hands on my face and her tongue in my mouth again. I knew Tanya had said I wasn’t allowed to do this, but I couldn’t help myself. I removed my hand from the small of her back and grabbed one of her magnificent tits. I didn’t even try to avoid her nipples, although I tried to make my grabbing gentle since she really seemed to like that. Tanya didn’t protest and, in fact, threw her hands around my neck so she could continue to support herself. That encouraged me to tug her shirt out of the way and start feeling one of her bare tits up. I wanted to see what I was playing with, but that would mean breaking the kiss with my sister. I kept kissing Tanya since that seemed to be the more urgent of my two desires. Damn! I thought I had been horny before, but making out with a girl at the same time I was feeling her up was dialing my horniness up to eleven. I twisted my body so that Tanya was bound to be able to tell that I was hard, but that didn’t seem to bother her either. It was another instinctive reaction. Tanya was making my cock hard and feel amazing, so it was only natural that I would want to rub it against her slim body. Finally breaking the kiss, Tanya gasped, “I’m going to have to be careful. I was just going to give you a chance to practice kissing a bit more, but those gentle hands of yours have got me wanting to make out.” Not needing any more encouragement than that, I squeezed on Tanya’s exposed tit a bit more and brought my mouth back to hers. She pressed her lips against mine eagerly, and once again, our tongues were dueling. If there had been a bed or couch handy, I’m pretty sure I’d have tried to lay Tanya down and have sex with her. However, on the steep mountain trail, we stayed standing and kept kissing feverishly. I guess all good things have to come to an end because Tanya broke the kiss and said, “Enough; there’s only so much making out siblings should do. If we keep this up, I’m going to end up as horny as you obviously are already.” As Tanya stepped away from me, I saw the most amazing thing. She hadn’t pulled her crop top down over the tit I had been feeling up. I got a clear, close up, unobstructed view of that marvelous jug! My mouth had already been hanging open from the kissing, but now my jaw really dropped. I immediately forgot my sister’s words, trying to slurp Tanya’s delectable nipple into my mouth. Stepping back and giggling, Tanya covered herself back up. “Now now, you need something to motivate you to behave on the way to the scenic lookout.” Then she trotted off down the trail. Had my little sister really just promised me a chance to suck on her titties? It certainly seemed like it! I hurried down the trail, hardly able to contain myself.
