The walk from the window where they'd peeked, despite the sexy talk by Betty, had caused Stacy's passion to simmer down a great deal. But now, as she watched the pony's cock getting hard and extending out and down at least eighteen inches, she felt the heat in her loins building and spreading again.
Betty looked at Stacy, her dark eyes flashing, her fingers still busy on the big balls. "Isn't that an exciting sight! I washed his cock late this afternoon. That's the reason it's so clean."
Stacy agreed that it was an exciting sight, but she didn't say anything. She even felt that she should turn tail and run like hell. But she couldn't seem to move her feet, and wasn't even sure that she wanted to flee. It wasn't as if she was going to do anything – and she was curious as to just how Betty was going to go about relieving her sexual tension with the pony's long cock.
She could tell that the long shaft had been recently washed. She'd seen horse cocks extend out many times while pissing and also when a stallion was around a mare in heat. She'd even seen a stallion fucking a mare a few times and that'd been exciting, but also quite frightening.
Betty got on her knees on the bed she'd constructed out of the hay and blanket and began caressing the long shaft. There wasn't any slime like Stacy had seen so often, which she knew was a lubricant provided by nature, and she successfully resisted an impulse to go over and touch the big organ. It looked so hard and sleek and it wasn't repulsive at all.
Betty looked at Stacy, smiled, and quickly positioned herself on the makeshift bed. She placed her crotch almost directly under the end of the stiff shaft and wriggled her ass until the big cockhead was resting against her cuntal lips. She was grasping the cock with both hands. She wriggled a little more, hunched upward, and four or five inches of the pony's prick slipped into her pussy. She began making fucking motions, lurching upward ever higher, soon taking seven or eight inches on each upward thrust.
Stacy could understand why the pony had been tied so that he couldn't lift his head. He couldn't lift up to make thrusts of his own, and she thought a little wildly that if he could really do any fucking he'd ruin Betty forever. As it was, Betty was using her hands as well as her own body movements to control the depths of the penetration.
Betty's face was contorted with passion. But she had her eyes open and she looked at Stacy and spoke without faltering in the steady pace she'd set.
"Pee-wee can usually last a long time. But I haven't used him and his lovely cock for a couple of days and I can tell that he'll be blasting off soon. He recovers quickly, though, and might not even lose his hard-on after shooting off his first load."
"Very interesting," Stacy said, feeling that she should say some damn thing, her eyes going to Betty's thrusting titties and then back to her cunt moving and clinging on inches and inches of the pony's long cock.
"Oh, sweet Jesus, I'm coming! Oh, Stacy, you can't imagine how good this feels! Oh, awwwww…"
Betty's lovely buttocks bounced and wriggled wildly, and a quick glance told Stacy that the passionate girl's eyes were tightly closed, her white upper teeth clamped down over her full lower lip.
Stacy was steaming herself. It took all of her will power to keep from clutching at her own crotch, her own quivering cunt. She didn't actually have an orgasm, but she could feel the secretions adding to the wetness of her already damp panty crotch.
In a few seconds Betty was still, her eyes open, a bright smile on her pretty face, her hands still holding at least eight inches of the pony's stiff cock embedded in her twat.
"Pee-wee didn't come, Stacy. As you can see! Would you like to give it a try?"
"No! Never!"
Betty laughed. "I think you protest too much, honey! But if you don't want to have some far-out pleasure that beats masturbation all to hell, then I'll take another trip and make Pee-wee shoot his stuff!"
While speaking Betty had started hunching again. Stacy stared at the prick and the pussy, her mouth and throat dry, her legs weak. But she didn't want to give her virginity to a pony!
Within two minutes the pony ejaculated. Stacy could tell that Betty had another orgasm as she swiftly fucked herself up and down on the spurting cock. The white sperm overflowed Betty's clinging cunt and Betty moaned loudly and cried out with pleasure.
Stacy turned, hurried to the door, opened it, and then took off running.
CHAPTER THREE
Out on the sidewalk, heading for home, Stacy slowed down to a jog. But after jogging for a couple of blocks she started walking, no longer in all that much of a hurry, even wondering if she should go back. She should've at least said goodbye to Betty. The uninhibited girl would understand why she'd taken off, though and she could always explain or apologize or some damn thing the next day at school.
It was a little over a half a mile to her home. It wasn't all that late, but it wouldn't've made any difference if it'd been in the early morning hours. Except for the lack of sleep, of course. She had her own key and could come and go just about as she pleased. She could handle her mother, drunk, drinking, or sober, and her father was always telling her to have all of the fun she could while she was young enough to enjoy things to the fullest.
She didn't think he would approve of the offbeat fun she'd enjoyed that evening, though! The peeking at the swappers had been great fun, too. That Betty! Fucking herself with a pony's cock! Pee-wee's cock was just about as big as a large horse's, though. But she wouldn't think about that! Hell, she might get nutty enough – or hot enough – to breeze out to the barn and do some experimenting with the five beautiful horses out there!
The big house was dark. Deciding that her parents were out someplace, as they never went to bed that early, Stacy thought about Betty's parents. They were a very attractive couple and the father was always smiling at her, flirting, really, and she wasn't surprised that they swapped. Betty's mother was something like Betty, a sexy-looking chick, and Betty was very broadminded to accept the truth about her parents without even telling them that she knew. She'd at least tell them how terrible she thought they were, Stacy thought. Not that her mother and father would do such a thing!
There was a combination cook and housekeeper, but she didn't sleep in. Stacy locked the front door behind her, then checked in the living room to make sure that her mother hadn't passed out on a couch – or on the carpet. Sometimes her father went out in the evening alone, but Stacy didn't bother to check the bedroom her parents used to see if they or her mother had gone to bed early.
She hurried upstairs to her room, closed and locked the door, and turned the light on. She couldn't remember the last time her mother or her father had been up to her room, as she had her own alarm clock, but she didn't want to take any chances on being caught doing what she just had to do.
Stacy pulled the shades down over the two windows. There weren't any dwellings close by, but there was always the chance that somebody could be spying with a pair of binoculars. She didn't like the idea that she might be watched, even if she had just engaged in and enjoyed voyeurism for the first time.
While stripping out of her clothes, Stacy decided that she wouldn't bother to get her collection of pictures. They were hidden under some clothes in a bureau drawer, and she'd spent many enjoyable hours looking at the vivid sex acts depicted in the brochures put out by various mail-order houses.
Her father was on many mailing lists, apparently, because he received many envelopes through the mail with "sexually oriented ad" printed on them. She'd seen him open such envelopes, then, after glancing at the contents, tear them into small pieces and toss them into the waste paper basket. She'd spent hours putting the brochures back together like a jigsaw puzzle until she'd decided that he wouldn't miss the majority of such erotic advertisements if she simply beat him to them. She let him receive enough so that he wouldn't get wise to what she was doing and she still got a kick out of going through the waste paper basket in his study.
