"Go ahead son, get nekkid," I repeated his phrase that had thrilled me two nights before, emulating his deep voice. "Don't be modest on my account."
Russ chuckled at my impersonation, and proceeded to comply. He bent and pulled his underwear down to his ankles, straightened and stepped out of them. Then he balanced alternately on each foot, pulling off his socks. I kept undressing while keeping a close eye on the way his thick penis and full scrotum swung back and forth as he did this. When he was done, he stood there and watched me as I finished undressing. This of course aroused me, and my penis started to fill and lift its head up, hovering slightly in front of my balls by the time I had put my clothes down and stood back up, facing Russ. I snuck a peek below his paunch and saw his penis was thick and full, but not yet erect -- another larger sock full of sand. We both turned and bent to get into the bag simultaneously, blocking each other, doing a little dance as each of us moved out of the way again, like people trying to get out of each others' way in a hallway. Finally, Russ stepped back and motioned with both hands like an usher for me to get in first.
Russ was fully erect now, and trying to hunch over to hide it. He knelt and slid himself in beside me. This time I had stayed facing the center of the bag, and got a good view of his erection up close, bouncing slightly as he slid his hips in past my face and into the bag. I wasn't shy about staring at his whole body as it passed by, and his face was bright red when he got all the way in. I grinned and waited for him to make eye contact, which he avoided for a few seconds, pretending to adjust himself in the bag. Then finally we were facing each other, up on our elbows, our bodies maybe a foot or two apart. I imagined our two hard penises pointing straight at each other, and wondered if their tips were very close to touching.
"Well," I said, "how do you propose we go about getting to sleep tonight, knowing we both have the same problem right now?"
Russ was still bright red, and breathing a little heavily, whether with arousal or the effort of sliding into the bag I couldn't tell. He licked his lips, hesitating.
"Well, if you're all right with it," he finally said, "why don't you lie back..."
I could tell he had meant to say more, but couldn't bring himself to it. I turned onto my back and raised my arms up, lacing my fingers behind my head. I saw Russ hesitating again, then he reached over with his right hand and slid it between the sleeping bag and my chest, brushing over the hair, up and down first over my right chest, continuing to my left, brushing each nipple as it passed.
"You know," he said, pausing. "We've kind of been making a mess of the sleeping bag this trip. What do you think about doing this uncovered? We could unzip the bag and leave it open till we're finished."
"Sure," I agreed. I wasn't going to pass up a chance to see more of his nakedness.
This involved more turning and sliding around and all the incidental contact that involved. The sleeping bags had to be unzipped most of the way around to free us. I ended up kneeling when the job was done, with Russ standing. His erect penis was standing straight up too, as was mine. We were both breathing a little heavily.
"Do you mind if we put this back on?" Russ asked, reaching up to the lamp at the peak of the tent. "If its not too weird, I kind of want to see what's going on this time."
"Sure," I nodded, thrilled at the thought of being able see more as well.
He turned it on, and I lay back down on my back, now as free and exposed as we had been on the grassy island. I laced my hands behind my head on the pillow. Russ lowered himself to lay facing me on his side, up on one elbow with a pillow stuffed under his armpit for support. With his free hand he resumed his exploration of my chest and belly fur, his eyes wandering down to my feet and back, pausing at my full-blown erection.
I took a big breath in and out, trying to slow my rushing heart, thinking about what was happening here. The last two nights had happened so quickly it had hardly seemed sexual. Tonight was different. Russ was naked and aroused, and the way he was brushing my chest and nipples was more patient, like he was focused more on my thorough enjoyment this time, not just helping me get to sleep. He didn't want to rush through this. He brushed down and around my stomach a few times, then spent some more time with my nipples. Finally he moved down past my stomach, and brushed his fingers around the highly ticklish triangles to the right and left of my groin.
I flinched each time he reached that area, and he grinned. "Are you ticklish?"
"Sure am," I admitted, and flinched again in answer as he swirled his fingers around either side of my groin. I gasped and giggled, "You're gonna make me cum," I squeaked.
He half sat up then, bending one leg under himself and freeing up both his arms. "I kind of thought that was the point," he smiled down at me, letting my body back down from climax for a few moments. Then he began to explore my body for other ticklish spots. He went for the obvious first -- my armpits -- digging his fingers in and wiggling them downward to the fleshy sides of my chest. I burst out laughing, automatically freeing my arms from behind my head and wrapping up his hands under them.
"Shh-shh-shhhh..." he warned me, "Walt and John are going to hear you."
He wiggled his fingers into my skin again where his hands were trapped under my arms. I huffed out quieter giggles, starting to squirm and keeping his hands trapped. He stopped until I settled and lay still, breathing heavy. Then he gently slid his hands out from under my arms and moved them down to my wrists, gently guiding them back up to my head. I took his cue and laced my fingers behind my head again. I noted that my penis had softened a little with the distraction of tickling, dipping over slightly but still half erect. Just that thought got the blood flowing back into it, though, and I got to experience again the delicious feeling of a growing erection.
As it rose below, Russ placed his hands on the tips of my elbows, one on each side, and slowly drew them down the skin of the underside of my arms toward my armpits. I could feel the skin of his palms and fingertips. They were the heavily textured fingertips of someone who works with his hands, but not hard or heavily calloused. I had time to savor the gentle roughness, the perfect amount of manly texture, as he ran them slowly past my armpits down my flanks on either side. My whole body shivered and I felt a wave of goose bumps thrill across the entire surface of my skin. I closed my eyes and reveled in the ecstasy of his palms traveling all the way down the length of me until he had to turn and switch his hands to opposite sides, where he continued from the sides of my butt down the outside of my legs, until he cupped my feet. I opened my eyes again, worried he was going to tickle the soles of my feet, my ultimate weakness.
