It is unfortunate that more boys don’t have a big sister like I had to help them through puberty. I mean that’s a tough time for everyone. But I had my sister and am I ever grateful I did.

We have always been close even though she is two years older than me. There were some rough times in our relationship when she was between 12 and 14 but even then, I sensed that she really would come through in a pinch, if it came to that. So by the time I was 14 and beginning to grow in all sorts of ways that I hadn’t expected, Jo was there to help out.

You see, Jo had a way of getting me to talk about whatever was troubling me. Even when I felt embarrassed, she would be able to throw her arm around me and after beating around the bush, I would finally tell her the problem. What made it impossible for me to hide anything from her was that she was always so open with me. She would not only tell me everything that was bothering her but she also seemed to have absolutely no immodesty around me. I mean, I was in her room once talking about some of the things happening around school when she began changing her clothes. I was certainly aware this was just my sister but I was also aware that most of my friends would have given anything to witness the show I got during the next few minutes. Keeping up her side of the conversation, she proceeded to strip down to her bra and panties. I had seen her this way many times so I wasn’t particularly shocked. But she continued to undress, slipping off her bra and tossing it on the bed.

“Tell me, Brother, do you think I have a chance to catch a boy with these boobs?”

I mean, what could I say. About the size and shape of grape fruit halves, there were these two gorgeous knockers in front of my eyes. I felt my penis stiffening involuntarily. “Uh, Sis,” I murmured, “don’t you think I’m a little too young for this?

“Huh? Oh, my tits you mean. Are you getting a hardon? Do I make you horny? Maybe, there’s a chance for me, after all. Hey, it’s been a while since we played show and tell. I’ll show you mine if you’ll show me yours. How about it?”

Without really waiting for me to reply, Sis slipped her panties off. With her hands on her hips she looked at me, full on letting me see everything she had. I really couldn’t tell what I should look at. Breasts were at that time in my life the most exciting “forbidden fruit” but that patch of curly hair at the base of her tummy fascinated me, too. I had a bunch of hair down there but it looked nothing like hers. And the last time I had seen her crotch it was sparsely covered as mine.

“Come on, Bobby,” she coaxed. “Get naked. I’m feeling horny and nasty and you know what happened the last time I felt that way.” I remembered with a shudder. We had been several years younger then but I still could clearly remember giving each other enemas and then rubbing lotion all over each other. It had been quite an experience.

Sis began rubbing her tits with one hand and her furry mound with the other. I decided there was really no way out so I proceeded to undress as modestly as I knew how considering the circumstances. I tried to hide my very erect cock but Sis insisted that I let her see everything.

Without warning, she dropped to her knees and kissed the head of my cock tenderly. “Why, Bobby, you’ve grown so nicely! Why have you been hiding this from me, you naughty boy?”

She had her hand around my balls so I didn’t dare even move but I felt like crawling into a hole. How could my sister do this to me? After kissing my prick, she began drooling over it, literally. She slobbered on it then sucked it into her mouth to lick away the slobber. She kissed down one side, then nibbled up the other. She sucked and swallowed as she slid onto my cock until her nose pushed into my tummy. The pleasure was making me delirious but at the same time I felt embarrassed for my sister. After all, all my friends used the term “cocksucker” derisively.

I stopped worrying about what my sister would be called and began REALLY worrying about what was about to happen. I was getting this strange feeling in my crotch that I felt few times before. If I tried to relax it felt like I was going to pee. And when I tried to tighten up so that wouldn’t happen it felt like I had built a dam and pressure was rapidly building up behind it. The pressure was now so high that I couldn’t relax and yet it seemed like any minute now, the dam would burst. I felt severe panic along with all the wonderful feelings Sis was giving me.

Suddenly, I knew it was all over. My cock began jerking uncontrollably and white, sticky fluid began squirting out with each jerk. I could no more stop the spurts than I could stop a sneeze. It was a wonderful feeling but so strange. I got a big gob in Sis’s hair and down one side of her face before she got my dick back in her mouth. After that, she seemed to suck it like it was a straw leading to her favorite soda. When my jerking subsided to an occasional throb, Sis slid my cock out and kissed the end, letting me see the white stuff ooze out with each throb. She didn’t try to lick all the stuff off, preferring to let it drip down her chin and onto her breasts. Later she rubbed it in there.

“Okay, now it’s your turn to look at mine,” Sis exclaimed. Laying back on her bed, she brought her feet up beside her hips and, in the process, spread her thighs wide. I could now see that there was a lot more to see than I had remembered. At the point where her pubic hair became thinner, a moist pink button stood. Beneath that was a darker pink area, roughly oval in shape, that seemed almost to be moving.
