"Tommy, how come you snuck out after you were supposed to be in bed last night," Tina asked, not loud enough for Mom to hear, but loud enough to make Tommy nervous.
Tommy had just turned fourteen last month and with the onset of puberty came a very healthy curiosity about sex. He had discovered that by peeking in the windows of his neighbors, he was able to learn a great deal that wasn't included in Dad's 'birds and the bees' speech, and certainly wasn't part of his Sex Ed curriculum. But now he had been caught. He pulled his younger sister into his room and gently shut the door.
Tina, at twelve, didn't have the physical development that her older brother had, but she had been developing the same curiosities lately. Somehow she had sensed that whatever Tommy was up to, it had to do with the strange feelings she had been feeling ever since a couple of her girlfriends at school let her in on a few secrets that suddenly made boys a much more interesting sub-species.
"You better keep your mouth shut, or I'm going to give you a good pounding," Tommy threatened.
"Ooooo! I'm sooo afraid! You beat me up, and you'll get it twice. Once for hitting me and once for sneaking out. Dontcha think it would be easier just to let me in on the secret?"
