I'm a "boomer," and when I was young, teen sexuality was "controlled," by and large, by keepking the girls chaste. If the girls were sexually pure, that was good and proper, although there was a bit more latitude for boys.
What this meant is that lots of girls who came of age in the 50's and 60's were brainwashed (somewhat) into thinking that sex was wrong, dirty, sinful, and genuinely nasty. Yeah, this all went by the wayside towards the end of the 60's, but girls tended to present themselves (truthfully or not) as modest, proper, and virginal. There was lots of "testing" as boys tried to get to first base, second base, etc.
So I've always found modest, virginal, shy (looking) girls very appealing. Also with long hair and long ribbons. I have to say, a teenage girl (I find the mid-teens cutest), in a nicely buttoned white blouse, pleated skirts cascading down to just above her knees, legs together, crossed at the ankles....combines as an image of subdued, restrained, but very hot sexuality that is a real turn-on for me.
Of course, it's not right for a girl to tease, even if she genuinely "prim and proper." So my fantasy is the slow, gradual stripping of the schoolgirl--who really doesn't want it--violating, degrading, and, yes, hurting her, garment by garment, step by step.
Intensely exciting to me is the image of a schoolgirl, flat on her back, on a dirty floor (floor of the school's heating plant?), pinned down. Her blouse is ripped open, her bra cut between the cups, and her 34-B tits pushing up for my vicious pleasure. Then her skirt is pulled up, fanning out on the floor to her sides, and her dainty satin half-slip his bunched up around her hips and waist. (Why don't you porno writers include pretty slips, huh?)
As the terrified girl roughly touched, groped, and explored, she is further tormented with psychological abuse, as I tell her what I'm going to do to her, and how she will never forget this experience, whenever she is intimate with any boyfriend or husband. I spend a bit of time rubbing my erection against her satin pantycrotch, emphasizing that only the thin, dainty fabric separates me from her virgin girlhood.
That's when her shiny nylon panties are ripped away, and she gets a long, hard, definitely not enjoyed fucking from a horny coot, old enough to be her father, and then some! Perhaps I make her separate her pussy lips for my entrance, or should I have her hold my cock and guide me in?
Viagra is a great boost for us older guys, and she gets a long, long, hard and painful rape on the dirty concrete floor.
