Chapter 1

"Take a look at the size of his cock!" Sara whispered to 
her friend, Allison. They were lying on the beach watching 
people walk by.

"He's huge!" said Allison.

The man was tall and muscular. His body glistened with 
lotion, and the muscles in his legs flexed with each step. 
But it was his cock that interested the girls. Visible 
under his skimpy swim suit, the tube of his cock coiled 
over the bulge of his balls, and the whole package pulled 
down the fabric of his suit.

"How would you like to get fucked by that?" asked Allison.
Sara giggled, "I can't imagine."

"I can," said Allison. "I'm imagining him covering my body, 
pressing me down, with one hand between my legs and his 
tongue fucking my mouth."

"You're so bad," giggled Sara.

"I'm not bad," said Allison, "I'm just horny. You're the 
one who's bad. While I'm getting fucked, you'd be sitting 
in a corner, watching. You'd be using one hand to get 
yourself off and the other one to play with your tits."

Sara looked at her friend. "Your hot pussy wants it, 
doesn't it?"

Allison blushed. "It always wants it."

"And people think I'm the dirty one. You came on my hand in 
the hotel room this morning, and I'll bet you fucked 
yourself in the shower before that."

"You know I need it a lot."

"You sure do. Why don't you pinch your nipples now? It will 
make you hotter."

"OK. I like being hotter." Allison shifted her shoulders 
and, making sure that her other arm shielded what she was 
doing she took her nipple in her fingers and pinched it. 
"Oooh."

"Now the other one."

Allison shifted and squeezed her other nipple. She 
sighed, and then she looked at Sara. "You were right.
That made me hotter."

"It's amazing how hot your nipples make you. I mean, you 
don't have any tits at all. Just think how sensitive 
they'll be if you ever grow any."

"I don't want to grow real tits."

"Why not?"

"I like to think about men fucking me while they wish I had 
tits. They'd be getting off inside me, and they'd want to 
play with tits, but they couldn't because I don't have any. 
But they would keep fucking me because they want to cum. 
They'd think that it was just like fucking a girl who's too 
young to have any tits, and that would make them shoot 
their cum way up inside me."

"God, you are SO perverted. And you're so skinny, if a guy 
ever fucked you, I don't think you could even see your body 
underneath him. He'd completely cover you up."

"I'd like that. To be completely covered up while I was 
being fucked. That would be great. It would be like he was 
pounding me into the ground."

"You're so thin, I don't think he could get his whole cock 
inside you."

"Oh, yeah! What a hot idea! Imagine getting fucked by a 
cock so big that you could see the outline of it moving 
around in your body. It would be so big it would stretch 
the skin over your stomach, and you could watch the bulge 
on your stomach moving in and out. Fuck! That would be hot! 
God, I want to cum again, but I can't out here."

"I've got an idea," said Sara. "Get up and take a walk for 
a minute, then come back."

"Why?"

"Just do it."

"OK." Allison got up and wandered around the beach for a 
minute. When she got back, Sara had arranged the sand so 
there was a mound under Allison's beach towel.

"Lie down here," said Sara, "And put your pussy right 
on that mound."

Allison lay down on the towel, arranged her body so her 
pussy was on top of the mound of sand and started making 
small movements with her hips. "Oh, that feels good. It's 
just like I'm humping a big fat hard cock."

Sara watched Allison humping the sand. "Tell me what you're 
thinking."

"I'm imagining that guy we just saw is lying on his back 
with his big cock bulging in his suit, and I walk up to 
him, and without saying anything I just lay down on top of 
him and start humping him."

"That's so hot! What do you think he would do?"

"I think he'd just lie there, because it would feel so good 
to have a teenage girl humping his cock. He'd just lie 
there with his hands behind his head and look at me while I 
humped him."

"People would see you doing it."

"I know. That's what makes it so dirty. They'd see me 
humping myself on his cock, and they'd see he wasn't making 
me do it, that I was just doing it because I'm a dirty 
teenage girl, the kind old men want to fuck." Allison 
was looking straight at Sara and her hips were moving.

"Would you say anything to him?"

"No. I'd just hump myself on him. But I'd be looking him 
straight in the eyes, like I'm looking at you, so he
could see me cum. I'd want him to see me cum... like...
I'm... doing... for you right... now."

Allison lay motionless for a moment, and then she said, 
"That would be so hot."

"You have the dirtiest imagination."

"What do you expect, being around you?"

"Me? At least I don't lay on the beach thinking about 
humping every guy who walks by."

"I can't stand this any more," said Allison. "Our parents 
won't be back until tonight. Let's go to the hotel and make 
ourselves cum."
