After the blowjob and finger thing I received from Larry, I wasn't sure I could even walk, but I knew we had to get going. Dad might ask questions about what happened to us if we didn't show up at a reasonable time back at camp.
We shortened our hike so we could still enjoy a leisurely pace back. During this time, when any change in the trail demanded an adjustment on our part, Larry would just sort of naturally and casually put a hand on my shoulder, or the small of my back, or even give me an "innocent" boost on my ass to help me along. I got those same ambivalent feelings about this mildly sensuous contact. On the one hand, I was still spinning from the thought that a man might make me feel the same way that girls had in the past, while on the other I was feeling just sort of warm and comfortable inside every time he touched me.
We arrived back at camp and everyone acted cool. Dad was oblivious, even though Larry continued to keep me wound up with that incidental contact every chance he got. We made it through the usual ritual with dinner, cleanup and star watching by a campfire. The only really strange thing was once, when Dad was distracted somehow, Larry actually slid his hand down the back of my pants, pressing a finger way down my crack. Then, while sort of squeezing everything, he said softly in my ear, "Don't forget; I have a special treat for you tonight". I was a little stunned and a little dense at first, but then it slowly dawned on me that Larry intended to continue somehow what he had started this afternoon when he had a couple of fingers up my butt while giving me that glorious blowjob. I was apprehensive, to say the least, but realized that we were already way over that line and that I might as well accept the fact that I had really enjoyed Larry's "treats" so far.
We got our showers and turned in pretty early. In no time Dad was snoring away again in his end of the trailer. I lay there apprehensively, wondering if and when Larry would "make his move", or if his touching and comments had just been some sort of playful teasing that I had misread. Just then, Larry started things off more or less like he had last night. He moved his hand over onto my lower abdomen and began rubbing slowly back and forth, moving under the elastic and ever so slightly closer to my penis with each stroke. Once he was definitely brushing the root of my penis, he moved his hand to cup my penis and balls. He grasped everything in his hand and began that wonderful soft squeezing motion. I was so hard already I was beginning to leak that clear pre-cum stuff.
Keeping up his ministrations, Larry tugged on my briefs. I realized his intent, raising my hips and helping slip my briefs down, kicking them off completely. Larry then sort of tugged and pressed on me, whispering "turn over on your side" into my ear. In a total state of abandon, I immediately did as he asked, without question. I was ready to do for him whatever he asked. I felt Larry sort of snuggle up to my back with his chest and stomach pressed against my back and something large, solid and warm lying down along the crack of my ass and thighs.
I thought I felt something a little wet too as Larry backed away so that he could begin to rub the head of his enormous dick up and down the crack of my ass. It felt really tremendous. At some point everything became quite slippery. Larry must have that same clear stuff coming out of his penis, only more so, judging by how wet everything was getting. By now, Larry had the huge head of his penis plowing the bottom of my crack, up and down, making delicious contact with my butt-hole on each stroke. It felt wonderful. Even though his penis had to be as hard as a fencepost, the head felt wonderfully warm and soft when he would let it linger at my hole and press slightly on each trip up and down my ass.
By now I was rubbing myself profusely and wondering just where this was going. On the next stroke "up", Larry left his penis resting just above my hole and I felt his hand caressing my butt cheeks. He pressed a fingertip against my clenched hole and just moved it back and forth across the sensitive flesh there, slowly getting everything to relax in response. Having learned a little from our earlier play, I was able to fairly quickly relax enough for Larry's finger to get in past the point of resistance. When it did, he began a delicious motion of sort of hooking and twirling his finger around the tight muscle getting it to relax even more. Then he left one finger in and began inserting another beside it, again taking his time and stimulating the nerve endings to the point he could have his way. Larry continued with the two fingers for the longest time, twirling around, thrusting in and out, occasionally picking up more of the slippery stuff from the head of his penis still pressing softly into my crack.
