But this only made him more aroused, more determined to give her the best he could deliver. His balls had tightened up into a hard sphere. The nuts churning inside pained him. He was going to have to get off and quick or go out of his mind.
Fucking faster, he started twisting just a little.
The corkscrewing action pulled him even deeper into, the girl's ass. Her soft, flesh asscheeks were turning slippery from the sweat off their bodies. His hairy legs ground into her rear and stimulated both of them to even higher levels of arousal.
Her tits pulsed wildly under his fingers. Taking one pebble-hard nipple between thumb and forefinger, he felt it growing stiffer. The nipple felt as if it would explode at any instant. He pushed it down into the soft marshmallowy flesh of her boob.
She shrieked and he felt hot come again. Her asshole felt like a noose tightening around his cock. He was sure she was going to rip him out by the roots as her body gyrated wildly, caught up in the powerful sexual release of her climax.
"Gotta go faster," he muttered. "Just gotta really butt-fuck you. Coming too soon! God, you're so fucking tight, you're makin' me come too soon!"
His hips blurred, as they fucked into the girl's ass. He was sheathing himself all the way into her clutching asshole. He rammed in harder, faster. He had to shove his cock all the way into her.
She came again. This time, he couldn't hold back any longer. She was shoving her ass into his groin. Grinding it in, whirling it around, she was doing her damnedest to get him off.
The white flood of his jism splattered into asshole. He whitewashed her rectum while pumping furiously in and out.
He gave her the sexiest enema she'd ever received.
Together, locked cock-up-asshole, they rocked through a mutual orgasm. Never had the girl felt anything this intense, this intimate, this sexy. Her entire body was one giant nerve ending. And that man's cock stimulated her to the point of losing her mind.
As they came down from their sexual high, she limply fell forward. The rock was hot under her naked body but she didn't care. Her asshole burned as if a flaming arrow had been shot into it. But she felt all warm and contented inside.
That was what counted, the way she felt inside. How could she have ever thought getting her ass fucked was perverted? It was as much fun in its own way as regular fucking or sucking a man off.
She heard his voice, as if in the distance, saying, "Enough? Or do you want to try it one more time?"
The way she rolled over and embraced him gave the man the answer. He wasn't going to escape her clutches until she was totally exhausted.
It took all afternoon.
CHAPTER NINE
"I'm completely out of it," admitted Joe. His entire body ached, but it was a good ache. His balls were sore from too much fucking, but there wasn't anything else in the whole world he'd rather do to get them in this condition.
Stretching full length in the sun, causing her tits to flatten as she arched her back, Ginnie said, "No chance for getting it on again?"
"Sex-hungry bitch," he snarled in mock-anger. "All you can think of now is fucking. I've created a monster!" His eyes rolled heavenward as if asking for help.
"It's your fault. You're the one who showed me how much fun fucking could be. I just can't believe I was so hung-up."
Her voice drifted off as she remembered what a completely different person she'd been just a few hours prior. Now, she was a woman of the world. She guessed she and Joe had done things that most of the other girls on this field trip had never dreamed of doing.
She shivered a little in spite of the hot sun as she thought how great it had been getting that huge prick all the way up her cunt for the first time. Or into her asshole. Or sucking on the tasty cock.
She'd done more in a short time than she'd done the entire rest or her life. If it hadn't been for the glow that still filled her, she would have been angry at her parents.
They'd lied to her all these years. Sex wasn't perverted or dirty or obscene. It was the best thing in the whole wide world! She couldn't guess why they felt the way they obviously did about fucking and sucking.
It must have been the generation gap.
"I've got to get back to camp and check up on the other hellions under my expert guidance," the professor said.
"Under you?" Ginnie asked. "I just bet the girls all are, literally. Have you fucked all of them?"
"Only Nancy. And you. And now that I've found you, I don't have to go hunting for anymore tail. I've got the sweetest ass to fuck right here in you."
He leaned over and kissed her thigh. Before long, he was avidly licking at her pussy, his tongue probing back into the darkest recesses of that flowing slash.
After Ginnie had come twice Joe sat up and said, "This time, definitely back to camp."
Through half-opened eyes the girl looked at him and said, "More later? Please?"
"Tonight," he promised. "I've got quite a yen for fucking in sleeping bags. It makes it a hell of a lot more fun when you're all tied up inside the damn thing."
"Tonight," she sighed, wondering how she could possibly survive that long without his wonderful cock-fucking her.
She lay on the rock for a short time longer untilshe was completely relaxed. A quick plunge back into the pool to wash off the sweat from a frantic bout at fucking, then a little more sun and she was ready to go back to the camp.
Phyllis was sitting outside the tent talking with Nancy. Ginnie heard her friend saying, "and then Frank really fucked me with that gorgeous prick of his. Shit, I never saw a cock that big! I mean, Christ, it huge!"
Ginnie brushed by the two and heard Phyllis comment, "I guess she's a total loss. Ginnie's got to be frigid. Did you see the way Joe was looking at her? And she shut him down!"
"Her loss, my gain," laughed Nancy. "I'll take all Joe has to offer all day long and as far into the night as he wants. God, can he ever screw. He goes at it like a fucking machine!"
Ginnie heard the two talking about her shortcomings and Joe's sexual prowess. Just hours before, she would have been outraged. She would have been blushing all the way to her toes. Not now. She knew what it was all about. Maybe better than the other two coeds.
She curled up in the sleeping bag, finding it extremely cold. As she drifted off to sleep, she wondered what it would be like having Joe in there with her. However it was, it wouldn't be cold. She'd bet a million dollars on that.
The others were milling around outside when she heard Dr. Preston telling everyone, "Curfew tonight. We've got to get going early in the morning."
Phyllis and Nancy crowded into the tent and waited for the man to pass by their tent. As soon as he was gone, they began chattering like magpies.
"Think I'm gonna sleep? Ha! I'm gonna get my bush over to where Frank can stuff his prick into it, just wait and see," Phyllis said.
"You and Frank, sure. Me, I'm going to get Ron all hot and bothered. I want to suck on his cock in the worst way possible. Just the sight of that guy's pecker bulging up in his jeans is enough to make me start creaming all over myself," Nancy announced.
Ginnie quietly listened. The other girls would be leaving the tent soon. That suited her just fine. Joe would come by and crawl into her bag and then crawl into her pants. And then he would fuck her even better than he had that afternoon. This time, she knew what was going down. She could return the fucking – measure for measure, blow for blow.
And it would be in the privacy of the tent with her friends gone off on their own erotic excursions. They'd be fucking their brains out in other parts of the camp.
"Okay, Nancy, the coast is clear. I don't see old man Preston anywhere. Good luck with Ron!"
