It was my buddy Joe on the phone. "Do you want to do our homework together ... and then maybe ... well just come over as soon as you can." I said I did and I would -- calculus was a little tough, especially in the 50s when all we had was a slide rule, and he was better at math than I was. I could use the help, and ..., was he hinting at something more interesting?

I got to his house at about 7:00 pm. His father, a widower, was working swing shift, and I realized as we went up to Joe's bedroom that we were alone in the house. Why was a sleeping bag on the floor in the middle of the room? I turned to ask him just as he was shutting and locking the door. Then I thought I knew, but I asked anyway. "What's the sleeping bag out for?"

"I supposed we would get into it," he said, matter of factly.

"What would we do?" I asked, innocently.

"I think you know," he said. "Wanna?"

He started undressing so I did too.

"Are you going to take everything off?" I asked.

"Yep," he replied.

This was great! Just what I had hoped -- we were going to get sexy with each other again. The first time we did it was about a month ago in my basement. We were just fooling around, kind of wrestling on the old couch and our dicks accidentally touched; they were both hard. I had known that mine was even though I didn't know why, but I was surprised that he was hard too. When they touched it was like a bolt of electricity shot into mine. Even though we were at that very horny age, like many guys of the time we knew next to nothing about sex, but once the dam was breeched by that accidental touch, we were ready to try anything. We maneuvered our stiff dicks back together again, this time on purpose, and after a few minutes of that we decided to pull our jeans down to cop a better feel. We were too modest to take down our underpants but it still felt really great when our hard-ons met. It was all I could do to keep from ejaculating and I would have if we hadn't quit. It must have been the same for him because were both ready to pull up our pants after about a minute.

The next two times we did it were on his bed after dark because we were still too modest to let our naked bodies be seen. We did get completely naked and lay together side by side with our hard cocks together. I was amazed how good it felt, the hard smooth flesh of his penis pressed against mine. But I was so nervous that I wouldn't be able to hold it and both times we only did it for a few minutes. Looking back, I wonder why we tried so hard not to let go with an orgasm. I guess we were just way too naive, completely amateurish.

But this time it was light in his room. Dim from just a desk light on, but still light. So, this was going to be the first time we would be naked together where we could actually see each other, except for the locker room of course, but that didn't count. Scary. As we undressed I snuck as many looks at his erection as I could without trying to appear too interested. His dick was a little lighter in color, but circumcised like mine. Mine curved slightly back toward my body and his was perfectly straight. I could see he was looking at me too and it made me a little edgy, but at the same time it was very titillating to have someone checking me out with such obvious interest. No one had ever seen my penis erect before, and, I'd never seen another hard-on either. It was very sexy. I was nervous as a cat.

Quickly we wriggled into the bag face to face. It was pretty cozy and we couldn't get away from each other but then that was the idea. Our cocks touched and the sensation was so fine, tucked cosily into that warm bag. I was amazed all over again just how wonderful it felt. We pressed tighter, self consciously wrapping our arms around each other -- where else could we put them? Our cocks huge, pinned firmly together between our bodies, we settled in. I lay perfectly still trying to get under control, trying to hold down that rising sensation in my groin. We must have lain there like that for several minutes. Then something really, really amazing happened. I opened my eyes and looked into his, just inches away. Some kind of nonverbal communication happened that I can't explain. We began to move closer as if some magnetic force was very slowly pulling. Our lips touched so softly that I could barely feel it. At first I was aware of a very soft pressure on my lips which gradually increased until, we were kissing. Neither of us had ever kissed anyone before but it came naturally enough. Not perfect at first but improving rapidly. I don't know how long or how many times we kissed. It seemed like hours but it was probably a minute. The first ones were dry, our lips puckered too tightly for any real appreciation of the sensation. But then we relaxed a little and the kisses became softer, moister. I was really getting excited, totally aroused as our soft puffy lips melted together. I wanted nothing more than to keep pressing my lips against his, to devour him, but suddenly I felt his cock convulse against mine and immediately mine answered. I tried hard but there was no stopping the orgasm. It came in several huge pulses and then it was over. Our lips still together, parted slowly. Again, we lay quietly, not knowing what to do or say. I thought he had come too, but I wasn't sure. If he hadn't what was I going to say. The silence was deafening.

"You came too didn't you?" he asked finally.

With great relief I said, "Yes, I couldn't hold it. Sorry"

"Sorry? Why sorry. It felt good didn't it? he said.

"Oh yeah! It felt fantastic," I said.

"It sure did. But we'd better get out of here now I guess," he said. "Try to keep the stuff off the bag. Boy there is a lot of it!"

He'd unzipped the bag and thrown the top back so we could see the big gob of semen pooled where our stomachs were still pressed together. Our cocks were still fully erect, but abruptly they held no interest for me. My sexual desire, so recently raging, was mysteriously gone. The two turgid dicks were no more interesting now than a couple of weiners. It's an odd thing, the refractory period that follows orgasm. Why did nature design us to flip-flop from orgasm to almost immediate lack of interest in sex? Being my first experience, I wondered what was wrong. Why had I gone from being horny as hell to couldn't care less about doing it again. But I was also about to learn that the loss of sexual desire doesn't last long.

Dressed, we approached the homework which now seemed like pure drudgery. Who could concentrate on school work after a mind-blowing, life-changing experience? But then after half-hour of plodding through most of the calculus problems and acting like nothing had happened between us, Joe suggested that if we get the homework done we might return to the bag for an encore. My dick, even limp, tingled at the thought. The refractory period, it seemed, was short. Another half-hour finished off the homework and Joe said "Wanna.....?" gesturing with his head toward the bag.

"I guess so," I said, coyly like I didn't care. In truth I wanted to get back in the bag so badly I could taste it, and I surely wanted to taste his lips some more. Not only was I ready again, I couldn't wait now that I had tried real sex. We undressed in a flash and had barely snuggled back into the bag when our mouths were locked in a ferocious kiss, lips fused. Neither of us had said a word about the kissing. It didn't seem to be necessary because we were going at it like a pair of old lovers on a Saturday night. We kissed for probably 10 minutes without stop, getting hotter and hotter. My hand wandered slowly down his back as we kissed. I had to feel his cock. My hand slipped between us and around his hard shaft, but once there I froze. He rolled slightly to give me more room, and a little moan muffled by my lips escaped from his mouth. Emboldened by his obvious pleasure, I stroked the soft skin of his turgid member, exploring its surface, comparing it in my mind to my own more familiar organ. He arched his back pushing the phallus into my hand. My cock needed some attention too and I brought the two together feeling that old electric jolt as his frenulum kissed mine. If we hadn't had an orgasm about an hour ago I'd of blown it right then. I knew I couldn't hold it too much longer anyway. But by then the hot kissing and cock-on-cock friction was too much. Suddenly we were out of control, out of our minds. We thrust wildly, grinding the two engorged organs back and forth, the two phalluses making passionate love. The second stupendous orgasm of the evening erupted, and this time no one was worrying about keeping the bag clean. Lust trumped caution and our wild thrusting continued long after the last tiny dribble of semen oozed out of our cocks. Eventually we stopped, satiated.

We lay there spent, for a long time not wanting to talk or move. Eventually, though, reality prevailed and we emerged from the bag. We dressed without talking, and I gathered up my homework. Finally I spoke. "I'll see you tomorrow at school," I said.

"Yeah, see you then," he said, and I left.

By the time I got home, showered, and got into bed, the memory of the sleeping bag adventures brought my penis to life once again. I ached to feel his lips on my lips, his cock rubbing mine, but I had to settle for jerking myself off. As I drifted into sleep, I hoped that this evening was just the start of something fantastically wild and wonderful and that we'd rub cocks forever.
