Lisa goes all the way

More days and nights passed in much the same fashion, Lisa and her monsterous companion staying cool and hidden in the daytime before exploring and foraging together in the evening, then curling up together at night. Of course there was also the sex. Well, not quite sex but sexual activity which was getting wilder and wilder.

Lisa knew that she must be losing her mind. Despite several opportunities she felt no compulsion to run. In fact, she had begun to feel a genuine affinity for the beast. She didnt even consider herself a captive any more, he was simply her friend or rather, her lover. It should have shamed her but in truth she had never felt sexier. It was as if she was in control yet also constantly in danger and that thrill excited her beyond belief.

It was also madness that despite having found several food sources nearby, edible berries and nuts, her favourite source of sustenance was still his cum. It was as if she was addicted, slurping it down whenever she could and always wanting more. As the days turned to weeks she worried about these things less and less until they were just habit.

Another of their habits she no longer thought about was taking three of the monster's huge fingers deep in her cunt every night. He no longer had to be so gentle with her, thrusting into her furiously at times as she came and came over them. She would lower herself down onto them and bounce, taking them easily with not the slightest hint of pain. They both knew it was almost time.

It was during one particularly vigorous session that it happened, the beast initiating the escalation once more. Lisa had already cum several times, stretched out by his hands and when he began to shift she thought he was moving to lick at her like he sometimes did. She got a shock when he knelt between her legs and proceeded to lift her up, one arm supporting her back as the other gripped her hip. She felt the impossibly huge tip of his cock press against her now widely gaped cunt and gasped. In truth his shaft was probably only marginally thicker than what she was now used to, but the tip was another story.

The monster held her aloft, sliding her slick folds against his rock hard cock as he looked her in the eyes. Once more he spoke his only word, clearly a question.

"Hurt?"

As Lisa looked up at him she knew that it would. That to have that thick piece of flesh press into her would be agony and yet she wanted it more than anything. Deep down she knew that she had beeen working herself up to this moment. They both knew.

She gulped as she shook her head.

"Not hurt... gentle." Lisa replied breathlessly.

The beast let out a long, low, satisfied growl, a sound Lisa had never heard him make before, then he started to press. Despite the fact that Lisa's cunt now gaped wide and was slick with her fluids, his cock met significant resistance. Thankfully the monster remained gentle, pushing slowly but firmly and eventually she felt herself begin to stretch and stretch until he popped inside. Lisa screamed but the beast remained calm, holding still and stroking her waist as he let Lisa get used to the sensation of having him inside her.

She soon relaxed and he pushed a little deeper, watching Lisa's reaction carefully. She smiled up at him so he pushed further, and further until he saw her wince. He had hit her womb and a shake of her head confirmed that that was her limit. Lisa leant forward to look and saw she only had about a third of him inside her, even that such an accomplishment she could hardly believe it.

"Gentle." she whispered.

The beast obliged, sliding his hips back but never pulling fully out, keeping his tip inside. He began to work up a steady pace and Lisa quickly warmed to it. So too did the monster it seemed, his breath becoming ragged as he relished finally breeding his human lover. As Lisa felt him battering against her womb more and more she realised he was losing control, not hurting her but showing all of the tell-tale signs that he was about to cum. It was then that she realised she never spoke to him about cumming inside her. How could she, he would never understand.

In that moment several conflicting thoughts coursed through her mind. Could she get him to stop? Did she even want to? Could he, whatever he was even get her pregnant? Lisa realised she didn't have long to decide... he was about to blow his load directly into her womb unless she did something about it. Right. Now.
