Morning came, or at least it might have been morning. Light shone through the hole in the roof, but the cave was as dingy as ever. Mark got up and stretched. He was horribly sticky from a night of sweating. He stripped off his shirt, but there was no water to clean himself up. He felt disgusting. In the corner, Amanda began to stir, her shirt was still open revealing her breasts. So last night hadn't been a dream. As Amanda adjusted to her surroundings she realised that Mark was looking at her, gave a gasp of surprise and quickly folded up her arms across her chest.
"I don't think now is the time to be worrying about modesty," Mark commented. "Something in this cave is making us incredibly hot and I don't want you dehydrating out of shame."
Amanda opened her mouth to make a barbed comment, but then thought better of it and relaxed her arms.
"I don't know about the heat" she said, "but something in the pollen of these plants is having a soporific effect. It could also be affecting our bodies ability to cool down."
"It doesn't help that there's no ventilation," Mark remarked.
As they were talking something was lowered through the hole in roof.
"Hello," Mark called out, there was no response.
As the rope lowered they could see that it was a bowl of green fruit, similar to watermelons, but the size and shape of a grape fruit. At least there captors were feeding them.
"Are they safe?" Amanda asked.
"Well it seems funny that they would march use all this way and lock us up only to poison us," Mark replied. "In any case we have to eat sooner or later."
Mark bit into the fruit, it was juicy and sweet, but somehow enormously refreshing. He devoured the juicy flesh ravenously. Amanda joined him and for some time they ate, not caring how much juice they got on there clothes. Both amazed at how hungry they were. Having sated themselves the pair collapsed on the floor, overwhelmed by the heat and bloated from their meal.
Mark found himself drifting off again. He wasn't tired, he couldn't be, he had been asleep for hours. Yet, somehow he found his head was becoming fuzzy as if his mind were out of focus. Strange thoughts drifted, uninvited, into his head. He couldn't be sure if he were awake or dreaming. The heat was stifling, his shirt and trousers drenched in sweat and sticking to him uncomfortably. In frustration he threw off his shirt and sprawled out across the floor. It didn't do any good and soon he found himself removing his trousers and lying back in his underwear. His mind started to wander again. He stripped out of almost all of his clothes, and yet he was still getting hotter and hotter.
As he turned his head back and forth, Mark caught sight of Amanda. Clearly in the same state as him she had stripped down to he underwear. Yet the heat wasn't bothering her. Amanda had thrust the fingers of her right hand between her legs and was massaging her pussy frantically. She was dripping wet, and Mark could see juice running down her legs that was clearly not fruit or sweat. Her eyes were clamped shut and her back arched, her gaping mouth gave out gasps of pleasure.
Mark's penis was all but bursting out his boxers and it took all his self control to keep from reaching down and grasping it frantically. He found himself tensing up from the effort, as Amanda's moans became louder and louder. In the end he had to give in and, stifling a moan he reached down and pumped frantically and his engorged cock.
At that moment Amanda's eyes shot open as her orgasm burst forth. As she cried out in desperate joy, Mark pumped harder and harder and then gave his own moan of pleasure as his cum shot out, drenching his boxers and flowing back over him. The pair collapsed, red faced and shamed, covered in their own juices, trying to forget what they had both seen.
Amanda spoke first, sitting up she looked straight at Mark.
"You want me," she said quietly, it was a statement not a question. "I know you do, because I want you. I'm bursting for you and it's going to happen. I don't know if it's the heat, or the fruit or something else but I need you. I know it will happen. We'll get naked and you'll get inside my tight cunt and I'll squeeze and squeeze it out of you. I'm so hot for you, so hot, I need you now."
So saying she got up and undid her bra freeing her rosy red apples. Amanda was delicately built and lightly tanned. She stood like a jungle spirit, enticing him. She slipped off her panties, revealing the neat triangle of hair made slick from sweat and her own juices. Mark still said nothing, but his rock hard penis spoke for him. Amanda sidled over, seducing him with her movements and stepped over his chest, facing away from him. Then she lowered herself, displaying her sex to him like an animal in heat. Mark inhaled the musky smell of sweat, juice and fruit. It was all to much for him and he leaned forward and devoured her, lapping up her juices like a man in the desert who has found his oasis.
Amanda let out another frantic wail and collapsed forward. She pulled open his shorts and grasped his meaty cock. Her mouth enveloped it, sucking and sucking like her life depended out it. Her pussy thrust out, forcing Mark's tongue further and further inside. The two continued frantically tasting each other for what seemed like hours, but could only have been minutes, before Mark started to shudder involuntarily and then exploded into her mouth and down her throat. Amanda gobbled up his cum frantically as though it were some delicacy, before she gave out and with a cry born of impossible tension finally released, thrusting her head back before collapsing. Mark's own head fell back, his face covered in her and the two fell asleep side by side covered in their own and each others pungent juices.
It was impossible to tell how long they were asleep, but when they finally awoke they found another bowl of fruit waiting for them on the floor of the cave. Amanda dived at the fruit and devoured greedily, Mark followed hardly any less ravenous. The fruit filled their stomachs, and quenched their thirst, but did little to cool them down. The heat of the cave was still intense and they could do nothing except lie back covered in fruit juice and sweat.
Mark was feeling increasingly delirious, but he thought he could make out the shape of Amanda crawl on all fours towards him. She was still naked, and sticky from the mix of juices all over hear body. Neither of them had been able to wash and Amanda's odour was pungent and overpowering. A few days ago the smell would have made Mark nauseous, but now it was an incredible turn on. His cock rose up rock hard, as if saluting her. He reached out to grip it, but at that moment Amanda sprang. Her lips locked on his and her tongued forced his mouth open. Mark gasped in surprise, which only let her in further. Their tongues dance. She tasted of juice and sweat and the faint tinge of his own semen. At the same time disgusting and arousing. He couldn't stop himself, his tongue was caught inside her mouth. Eventually she let him go, breaking the kiss just long enough to lean one leg over and straddle him.
Mark looked up as she sat perched on his chest. She was flushed with excitement and arousal, her breasts, like soft apples, seemed to have swelled somehow since the previous day. Her pussy lips were engorged, red and so inviting. Somehow Mark's cock was even harder than it had been before. It took all he had to stop himself from snatching her up and forcing himself on her. Just as he was starting to loose his grip Amanda raised herself up and, holding her sex open with her left hand, gently lowered herself on to his penis letting her moist pussy envelop him. Mark let out a sigh of release, it was like coming home. Her vagina warm and inviting, massaging him firmly, but gently. Then she began to move raising herself up so slowly, and then collapsing all at once. Mark could not imagine how he did not come there and then, and yet he held on. Amanda carried on, rising and falling, Mark thrusting up to meet her. The pair moaned in ecstasy as they rose towards climax, like a boat on a river raising towards the waterfall. And then over the top, they released. Amanda's juices erupted from her all over Mark as he came inside her, his semen flowed like piss, seemingly never ending. Amanda crashed forward onto his chest. Mark wrapped his arms around her tightly and they kissed again.
Once again they slept, not knowing how long. But, when they awoke this time they were naked and wrapped in each others arms. They kissed long and deeply. They were interrupted by a widening shaft of light, as the stone was rolled away from the door. The tribe were releasing them. They emerged blinking in the sunlight, into the welcoming arms of the tribe who embraced and kissed them as new members. No-one spoke, they didn't need top any more. Mark and Amanda simply understood. The combination of the pollen and the fruit had changed them. Their sex drive had increased, as had their personal connection both with each other and the tribe. It was a form of telepathy. They could not read thoughts, but they knew what each other were feeling.
Mark and Amanda remained with the tribe. They lived in the shelter of trees, naked in the warm sun. Like the other couples in the tribe they kept largely to themselves, never speaking but understanding each others needs and desires. Every few days one or both of them would join a gathering party looking for food, and, on rare occasions, new converts to join the tribe. When new converts were found they would be lead to the cave, and after a few days they would emerge as lovers and tribe members. Amanda and Mark would smile and embrace the new members, remembering their own initiation. Then they would return to the shelter of the trees and make love for hours.
They spent much of their time making love now, they couldn't bear to be apart for more than few hours. They would fall asleep each with Mark's penis resting gently in Amanda's moist vagina, only to awake ready for each other again, they never tired of each other and their lust never diminished. After a few months of near constant sex Amanda fell pregnant with their first child, a daughter whom they did not name. There was no need, they instinctively understood her and her needs just as they did each other.
