BDSM Beach Part Seven The wind blew Cassie's hammock, causing it to swing just a little bit. The cool air sent a ripple of goosebumps down her naked flesh. The wind also blew across her clamped nipples, which reminded her of how sensitive and painful they had become. Her freshly spanked ass could feel every crisscross of the hammock's rope netting beneath her. She struggled against the pain, but the thin rope that wove around her limbs and into the hammock held her tight. Her struggling only caused the hammock to swing more, which caused her heavy breasts to swing further and upset the clamps even more. It was just another beautiful afternoon in paradise. After the morning spanking and breakfast, Kevin had ordered the girls onto the porch, where Julia had set up four hammocks. One by one, he had tied the girls into their hammocks. Thin rope laced and wrapped their ankles, thighs, wrists, elbows and collars to the netting of the hammocks. The process took a long time, but Cassie savored every minute Kevin spent binding her body. It was the most he had touched her since she had come to Cancun. Once the girls were all bound, Kevin toured them as though they were dishes served up for his pleasure. Cassie watched him suck on Alisha's plump tits. She groaned as she watched him finger and stroke Melinda's cunt. She grew wet as he bit Danielle's thighs. It was all worth it when he'd come back to her and run his fingernails over her body. Soft, wonderful not-quite-scratches started at her lips and went down her neck, over both breasts, across her hips and down her thighs and ended at her feet. Every inch of her body was ready to be taken. That was when Kevin had put the clamps on her nipples. The cruel rubber tips pinched her nipples and set her breasts on fire. A little index card had been attached to each clamp, so that every time the wind blew, it would catch the cards and twist her nipples. Cassie bit her lip and stared down in wonder at the abuse her nipples were going through. The pain was intense, but it was a good kind of pain. It was the kind of pain she wanted to remember forever. While Kevin applied the clamps to the other girls, Cassie found herself thinking about Julia. She didn't know where Kevin's submissive had gone, and she was surprised by how much that disappointed her. Ever since Julia had kissed her, Cassie was having the hardest time not thinking about the older woman. With the final set of clamps in place, Kevin pulled up a chair and opened a book. Cassie, and the others, moaned in frustration. Bound, helpless, horny and clamped, the girls could do nothing but anticipate his next move. He hadn't forbidden them to speak, but none of the girls was brave enough to talk. They were all afraid of being the one to come across as greedy or rude. Well, for a good 10 minutes, at least. "Kevin, sir," Danielle said. "Please don't ignore us." Cassie felt a strange flash of irrational anger. How dare Danielle, who'd been in Kevin's bedroom last night, ask him to disturb his reading? She realized that she was more upset that Danielle was being rude on behalf of all of them then she was jealous that the other girl had gotten more attention. Kevin snapped his fingers at Danielle, never lifting his gaze from his book. That was that. She was smart enough not to ask again. The girls laid in their hammocks on a lazy Cancun morning. The wind toyed with their clamps as the ropes ignited with their libidos. The sun warmed their bodies on the outside, while wicked thought warmed them from the inside. After a period of wet frustration, Kevin put his book down and returned to his captives. He started with Cassie, and somehow, that felt to her like a victory. He brought a bottle of water with a straw and placed the straw on her lips. She wanted to do something sexy with the straw, but she lost her nerve. She sucked down on the straw and eagerly drank the water. When Kevin took the straw away, Cassie tried to say "thank you" but no words came from her mouth. He reached down with both hands and removed her clamps. The pain had become a dull constant reminder, but once the clamps were removed, the blood came rushing back to her sensitive nipples. Cassie thought the clamps had hurt before, but now she knew just had bad the pain could be. She cried out and tugged at the ropes holding her down, struggling to reach her nipples and somehow comfort them. Kevin chuckled and moved on. Melinda cried out, and knowing that the pain was too much even for a tough athlete gave Cassie a small amount of consolation. Danielle screamed next, her cry dwarfing anything the previous two had yelled, while Alisha merely whimpered when her clamps were removed. Cassie watched as Kevin returned to her. He opened a box and pulled out more rope. For a brief moment, she was terrified of what he could possibly do next that would require her to be tied down more. Her fears evaporated as he pulled out a long sea-blue vibrator. Kevin slid the vibrator into Cassie's cunt. The cold plastic filled her slick pussy and then slid partway out again as he teased her. With only a few inches inside her, he stopped. He laced the new rope around the rope already wrapped around her thighs. In a few minutes, he had created a cradle for the vibrator that would keep it in such a teasing place. Then, he turned it on. "Oh!" Cassie whispered. Her cunt was so ready and sensitive that even the partial penetration was making her squirm. The hammock held her tight, and she found that her most vigorous twists and pulls only caused the vibrator to dance and squirm inside her. There was no escape and no way to get the full thrusting she desired. Kevin gave her thigh a squeeze before walking over to Alisha. Cassie could tell he was doing the same thing to Alisha, but she didn't care. She was still trying to get some sort of satisfaction from the vibrator. The ropes held her to the hammock, but she found out the hammock itself wasn't very solid. Suspended in mid-air, she clenched her thighs, crunched her stomach and pulled with her wrists to try to get the hammock to stretch just enough to allow her to get in a few more precious inches. The best she did was one more wonderful vibrating inch, but it didn't discourage her from continuing to try. The other girls were struggling more, too. Melinda was twisting so much that Cassie feared her hammock would break. Danielle appeared too exhausted to give it an honest try, no doubt worn out by her orgy last night. Alisha had no such problem, although she was as round as Cassie, and the curve of the hammock didn't allow for much wiggling. Cassie could see a puddle on the floor beneath Alisha, and she realized it must be where her cunt's desire had dripped. Cassie wondered if a puddle were forming beneath her, too. It was going to be a long day in paradise. To be continued.
