The three headed upstairs. Dan didn't bother putting any clothing back on at all, but had the two girls leave on their wrist and ankle cuffs so they "could stay used to being captives." This brought a couple of giggles, but actually both of the young women found it exciting, knowing they could be restrained at any time. Lisa had spent almost all of the time she had been here before completely naked, but this was Diana's first experience of going without clothing for any length of time. To her own surprise she had quickly adjusted to the constant nudity and loved the feeling of both freedom and bondage that seemed to go with it. She had never spent much time out of doors naked except for some private sunbathing - she and Lisa had done that last week, in fact - but up here was so isolated and quiet that it seemed natural to go outdoors without worrying about who might see.
The three dug around in the kitchen and put together some sandwiches, fruit, and snacks and shoved these into a picnic basket they found. Lisa picked up a couple of beach towels and Dan disappeared for a minute and returned with a large cotton blanket and a small cloth bag and the three headed out the back and down to the pond. The day had warmed up again and the lack of clothing didn't bother them. They spread the blanket, but Lisa wanted a swim before they ate. Dan had them remove their cuffs - no use ruining the leather. The three spent the next twenty minutes swimming and playing grab ass around the float until finally hunger drove them back out. They dried off and Dan replaced their cuffs. The three flopped down on the blanket and began to attack the food.
Diana asked Dan, "Lisa said you hadn't really played many of these games before, but you seem to know just what to do - and how hard, for that matter. You're really new at this?"
"Before last week I'd only played a few spanking games, but I'll admit I have a rich fantasy life. Not as good as this reality, but rich. And I do read a lot."
"I'd like to see your library," Diana said, only half teasingly. "I don't care where you learned, but I've loved every bit of it. And I expect to leave here with stripes like Lisa had last week."
Dan looked sharply at Lisa, who shrugged. "I guess they weren't all gone before she got a glance. I'll have to be more careful next time."
Still looking at her, Dan said, "Humm. That kind of carelessness probably calls for more punishment, don't you think?"
"Most certainly," Lisa grinned. "I'm sure you'll really have to whip my ass."
"Well, since I saw it," Diana added, "I think you should whip my ass too. OK?"
"I'm sure there will be enough to go around for both of you. You know, you two are the sexiest women I've ever met. In fact you are hotter than any I've ever imagined. This all seems so much like a wild dream I think maybe I should pinch myself. But I think I'd rather pinch you two." As he said this Dan reached out and caught a nipple in each hand and squeezed them between his thumbs and forefingers. Lisa and Diana both sucked in their breath, but both also arched to thrust their breasts farther towards him. The three of them spent the next forty five minutes feeling, kissing, stroking, and in general making out. Dan would be locked in a full length press with one girl and the other would push herself against his back and let her fingers play with his balls and anus. Once, at Lisa's silent urging, Diana wet her finger and worked it inside Dan's rear hole. His response indicated he liked this stimulation and Diana, to her own surprise, also found it exciting. She had had a few fingers in her own ass and during the last day Dan had introduced her to all kinds of anal stimulation, but she had never done anything along those lines to any of her own boyfriends. She was finding she liked a lot of things she had never tried.
Finally Dan reached into the cloth bag he had brought and pulled out a couple of lengths of rope. "I think we should stretch one of you now. I think maybe Diana first." he tied the rope ends to her wrist cuffs and then had her lie back on the blanket. They were in a small grove of shade trees and Dan used two of these to tie her arms widely spread. He then added two more ropes to her ankle cuffs and used another tree and a stake which he drove into the ground to spread her feet four feet apart. With Diana now stretched tightly on her back, he turned and embraced Lisa. After a long, deep kiss and a bit of feeling, he said, "Come on Lisa. Let's see if she's ticklish."
Diana's eyes popped wide open. She was not only ticklish - she was very, very ticklish. Dan began to run his fingertips lightly up and down her sides, across her stomach, and along her thighs. Diana broke into fits of laughter and strained and twisted against the ropes. "Come on, Lisa. Help me out."
Lisa thought, "What the hell. Why not?" She knelt on one side of the stretched brunette and began to let her own fingers dance across the taut skin along with Dan's. Soon Dan began to let his fingers wander across her breasts and along her pussy lips. Lisa hesitated only a second and then joined him in tormenting these areas too. She even let her own finger tease Diana's anus and actually penetrated her pussy a couple of times. Finally Dan stopped the tickling and began to run his tongue across her swollen nipples and down her now sopping slit. He was sucking on Diana's right nipple when he suddenly reached up and put his hand behind Lisa's neck. He gently urged her down, and with only a second's resistance, Lisa lowered her mouth to her friend's left nipple. Diana didn't object. She arched her back as much as possible, bringing her tits closer to the two hot tongues busy working on her.
Soon she was squirming uncontrollably and started begging, "Fuck me, Dan. I need you inside me. Fuck me now."
"Not quite yet," Dan said. "I want to get you properly aroused first."
As Diana cried out in frustration, Lisa suddenly stood and started for the house. "I'll be right back. Just keep on with what you're doing."
Dan didn't lift his head, but gave what might have been a wave in acknowledgment. He continued to stimulate the bound girl, driving her higher and higher. He was now getting almost too aroused himself to wait much longer. Somewhere in the back of his mind he heard Lisa come out of the house and saw her start back towards them, but he was too busy to pay much attention. He stretched himself out above Diana, supporting himself on his hands and knees. He lowered his head and sucked hard on first one and then the other nipple. He placed the tip of his rock hard cock against the entrance to her slit and pushed just the head inside. Diana strained upwards as far as her bonds allowed to try and get him in deeper. Dan finally let himself sink in all the way and pressed her hard against the ground. For half a minute the two ground their genitals together, not withdrawing at all, but pushing and twisting against each other. Suddenly Dan felt a slick finger at his own anus. He looked back and saw Lisa kneeling between his own (and Diana's) legs. She had her finger extended and was twisting it deeper and deeper inside of him. As her finger probed and lubricated, he pressed even harder against Diana's tight pussy. Suddenly Lisa withdrew her finger, but almost immediately Dan felt the end of something - must be a dildo, he thought - press against his now open rear. Slowly the plastic shaft began to penetrate him and suddenly he realized that this fake cock was mounted in a harness around Lisa's waist. She was fucking him with a strap on as he fucked Diana. In fact, although Dan didn't know it at the time, the other end of the dildo was deep within Lisa's own pussy and she was also fucking herself as she fucked him. Dan responded and began to move in and out of Diana as Lisa moved the hard shaft in and out of his own rectum. Lisa stretched herself against Dan's back and, not surprisingly, the intense stimulation very soon had all three exploding in the convulsions of incredible orgasms.
Finally they collapsed in a hot, sweaty heap. Diana reveled in the weight of both of them pressing her against the ground and tightened her internal muscles around Dan's shrinking member. At last the three pulled apart and Dan turned and embraced Lisa for a long kiss. Then both of them turned and, without a word, bent to suck hard at Diana's nipples. Suddenly Lisa began to let her mouth move down across Diana's taut stomach and on over her newly shaved mound. She moved between Diana's legs and began to lick the length of her slit. For several minutes her tongue darted over Diana's clit and in and out of her pussy. Dan sat back and stared intently, his hardening cock indicating his reaction to this show. Soon Diana came again in another loud climax. Lisa made one more long lick from just in front of Diana's anus, up through her slit, across her clit, and on up her stomach and over a hard nipple. When she finally pulled away, she and Dan began to release the stretched girl from her bonds.
As Diana sat up and worked her sore arms, she turned towards Dan and gave him a hug and deep kiss. Then she turned to Lisa and gave her one too. As she pulled back she quietly said, "Well, I guess we know how we feel about this, now, don't we."
Lisa looked into her eyes, nodded and said, "I guess so. It feels awfully good, but don't expect me to give up men."
