My first story

I don't have a name for it. I'm not going for any real story here, just good old futa/f action.

Samantha (or as her friends called her, Sam) was having trouble concentrating. Her best friend Jenna was laying on the bed right in front of Sam, her gorgeous breasts hanging down, exposing Jenna's considerable cleavage. For a normal high school girl, this wouldn't pose any problems. But Sam was no normal high school girl.

Sam had recently come into possession of a penis. A real dick, right in the spot where a dick would be on a guy. Her pussy was still there and she was for all intents and purposes a girl, but for some reason, just over two years ago when she first turned 15, she woke up with a massive, 16" erection. She did what any other teenage boy who first discovered the joys of morning wood would do, and afterwards it shrank to a very odd size - just under one inch. Whenever Sam would get horny, her cock would practically explode to nearly twenty times its flaccid size, and the erection would only go away after she came. To this day she still doesn't know why the penis suddenly appeared there on her fifteenth birthday, or why she didn't grow any balls, and frankly never wants to find out, preferring that nobody find out about it.

Sam had been able to keep it under control for a while, but lately she had been needing to cum more and more to settle her thick meat staff, and what's worse is that she had been growing more and more turned on by girls, particularly her best friend. All of Sam's concentration was focused on keeping her dick from bursting through her tight pants (the unusually small flaccid size of her cock made it possible for her to dress like a normal girl).

"Sam, you OK? You're looking a little pale."

Jenna's words jolted Sam from her daze and unfortunately jolted her dick as well. Sam could feel the blood rushing down to her nether regions, so she got up from the bed where she and Jenna were studying.

"Yeah, I've just got to, uh, go to the bathroom. I'll be right back, Jenna."

"Oh, OK!" Jenna said, bubbly and cheerful as ever. "Don't take too long though, this chemistry homework is reeeaaaally getting to me."

The way Jenna emphasized the word "really" was so seductive that Sam couldn't control her pulsing cock anymore as it strained and tugged at her panties as she made her way to the bathroom, closing the door just as the buttons on her jeans burst and her 8-inch (and growing!) cock stood triumphant, sticking straight out and slightly up from her crotch. Sam leaned against the bathroom door as she took her nearly fully-erect cock in both hands and began stroking it slowly. Sam's thoughts drifted to Jenna as she closed her eyes and sat down on the bathroom floor, still leaning against the door. Sam's shoulder-length blond hair rustled as her hands began moving faster and faster over her fully-erect cock. Sam couldn't stop thinking about Jenna - those delicious breasts, her hazel-col
