The pussy juice was tart and sweet. It tasted like the fluid that came from her own cunt. She'd never produced so much of it though. Maybe if she got licked off by a dog, she would. She lowered her lips to the seat and lapped up the cunt juice until the dog started lapping it up, too. Then she sat up, suddenly horrified by what she'd been doing. It was as if she'd temporarily lost her mind.

As she straightened herself, she realized that she'd glimpsed something, something she had to get a look again. She leaned to the side again slightly, peeking under the dog's black-furred abdomen. His prick was standing up out of its sheath-red and wet and quivering.

What shocked her was not that the dog had a hard-on, but the size of the Lab's cock. His cock looked to be five inches long, maybe six-the size Tim's had been a few years back, before it had surged in size like a growing cornstalk. She'd never seen a dog with such a thick and long cock.

"Hung like a horse, isn't he?" Peggy said, sitting up straighter. "When a girl's got a hung dog around, she doesn't always have to go chasing after the boys to keep her satisfied." She gave Denise a dirty grin as she played with her own tits.

Denise shook her head, unable to believe Peggy, unable to believe the size of the dog's cock, unable to believe what she, herself, had just done. She looked up front.

A girl was leaning out into the aisle, her eyes rolled back, her hair dangling toward the floor. A boy was clutching her, his hand down her pants and pumping as he apparently fucked his finger inside her cunt.

More boys and girls had paired up now and were sharing seats. Half the kids were engaged in necking or kissing or groping, Denise expected at any moment to see a boy rip off a girl's shorts, pull out his stiff cock, and ram it up her cunt right there in front of everybody. Things were getting out of hand, but the bus driver just stared straight ahead, driving them down the highway.
