All characters are and were 18 or older at all times where there were any sexual feelings or contact.
Growing up I had two sisters, one a year older and one a year younger. We grew up in a conservative part of the Midwest with our mom and dad. I was a fairly normal guy, though a little bigger than average, who was so devoted to sports I came upon other things in life a little later than most.
My mom and dad were pretty normal conservative folk; they and I sometimes thought my sisters were from a different planet than we were.
My older sister Jill at 19 was tall (about 5' 11", only about 3 inches shorter than I am), had an athletic build, long blond hair, and steely gray eyes in an otherwise very nice (though not gorgeous) face. Also – I only started noticing this when I was 18 – she has very shapely legs, a bubble butt, and high poke-in-your-eyes tits. She is a perfectionist, and was also a late bloomer. She works at something until she gets it right, and has from the time she was a little kid. Two examples:
She had a volcano as a science experiment she designed when she was about 10. She made, at one time or another, every member of the whole family help her set up and test her volcano at least 20 times over a three day period before the science fair. Of course it worked perfectly then, and she won 2nd prize.
As a second example, when she was 14, though she had never played softball before, Jill decided she wanted to make the high school team. She made our dad, me, or both of us play catch with and/or pitch to her at least an hour every day during the entire summer. Sometimes she would have me and some of my friends out there three hours playing with her even though her skill level was way below ours. But she was always kind to me and fun, and my friends always liked her, so there was no problem. Needless to say she not only made the team but ended up the starting first baseman.
Jill was also outspoken, and had no problem saying what was on her mind. This sometimes got her in trouble in school and with our parents, but she was always sly and smart enough to get out of it without significant consequences.
My younger sister, Kate, is very different. She is short, about 5' 3", with short brown hair with natural streaks of red, green eyes, a beautiful face, totally curvatious, and top heavy (her tits were way too big for her slim waist). She is usually a typical follower. Not as smart or as talented as Jill, she still wanted to do most of what Jill did, and succeeded most of the time (although to a lesser extent) in school and sports, and was probably the most popular girl in her class.
Soon after Jill turned 19 I started noticing changes in her behavior. She started wearing makeup and skimpier clothes, seemed to grab her crotch and breasts a lot around the house, and often asked me weird questions about guys at school. My mother apparently noticed changes in her too. One day when I was going through the medicine chest in the bathroom I shared with my sisters I came upon some prescription pills of Jill's, each pill separately packaged in a blister pack. She walked in about that time, took them from me, and said something like "Mom said you're not supposed to see these pills she got me from the gynecologist," and walked out with them.
One summer day before Jill's senior year and my junior year in high school, our parents went for an overnight at some relative's house, and we three kids were alone for an entire Saturday and Sunday morning. We did our own thing during the day Saturday, Jill and I cooked dinner, the three of us ate together, and since none of us had any plans with friends we played some video and card games, and then decided to watch a DVD. Kate didn't like our choice and said it was that time of the month for her anyway, so she went to bed about 10, leaving Jill and I with the movie.
The movie had many sex scenes and sexual overtones, and Jill was acting weird, including rubbing body parts, and squirming around, apparently immune to the fact I was nearby. At one point she said she had to pee, told me to put the movie on pause, and came back wearing only – as far as I could see – a long T-shirt. Her constant rubbing of her crotch and tits were too obvious, and I didn't like the effect it was having on me, so I asked her "What the hell are
you rubbing yourself for Jill?"
To my surprise she put the movie on pause, turned to me and said "Tom, have you had sex with any of the girls at school?"
I wasn't sure I wanted in on this conversation, especially knowing her characteristic directness, so I said "Should we really be talking about this?"
She then turned the movie off, sat next to me on the couch with her legs crossed and her T-shirt hiked up near her crotch, and made it clear that we were going to have a discussion about sex. So I swallowed hard and primarily listened, because even when she asked me questions she rarely waited for an answer.
In her typical direct manner she said she had started to really badly want to have sex, but thought she was way behind other girls, and didn't want to make a fool of herself with sexual partners. She told me I should be interested in that too, and that the best way for us to go about it to gain some experience without being buffoonish was to experiment with each other. She said she had gotten as much information as she could from reading, and now needed some actual "field work".
With that, she stood up and pulled her T-shirt over her head, exposing her glorious – My God was it Glorious – completely nude body. My dick was instantly rock hard.
She apparently was a little non-plussed by my wide eyed, gap-jawed, staring, and barked – "I know you're on porn sites all the time; you've seen naked women before. Now I need your help because I don't have a dick, or a tongue that will reach the places I need, so you have to help me out. Now close your mouth and take off your clothes."
To be honest, I felt like a zombie at that point, my mind shanghaied by the site of her breathtaking body. Knowing how relentless Jill was and how anxious I was to see where this was going, I did as instructed. But I was still inhibited and undressed hesitantly, so she got impatient and started pulling my clothes off faster. Her first
comment when my boxers dropped was,
"Wow, is your dick always like that?" to which I replied "No, only when it's aroused."
