"That feels so good," she moaned timidly. "No, don't stop, you can kiss me again later. Please, just keep doing that."
Gerald needed no such encouragement. Things were happening too rapidly for him to repress his thoughts any longer. He was going to go as far as possible with his gorgeous sister, fuck her if she gave him the chance. He had wanted it for over a year and there was no point hiding from the truth now that they were together.
As his tongue continued its slow agonizing movements, Gerald moved his hands up and down Donna's curvaceous torso, getting closer and closer to his goal. He had to feel her snatch closing around his probing fingers. The girl was ready for it, was making no attempt to resist him. She was a hot little piece, all right, her desires as strong and irresistible as his own.
Donna had indeed abandoned herself completely by that point, feeling her arms wrapping themselves around her brother's hot, sweaty back. Thought was out of the question. Instinct predominated. Fifteen years was long enough to wait. Donna was old enough to have sex. She wanted it badly, knew that somehow her brother would unlock the secret of sex for her. She was frustrated, but Gerald would show her the way sooner or later.
The storm seemed to have moved from the external world into the fruitful field of her virgin body. Each time Gerald's hand approximated her dripping cunt Donna could feel herself getting hotter and more aroused. Sex seemed hard and uncomfortable to Donna but she would not have traded it for anything in the world. At last her loving brother was turning her into a real woman.
Finally the deed was done. Donna felt strong fingers closing around her pubic bush, rearranging the incredibly soft, blonde pubic tresses. Her labia closed momentarily, an unconscious defense against the violation that she knew was coming, but that too turned Donna on all the more. She didn't know what she wanted from her brother but Gerald knew and it was impossible to do anything but place herself in his confident care.
The fifteen-year-old virgin gasped aloud as she felt Gerald's forefinger part her labia and enter into the citadel of her twat. His finger seemed too large and rigid, almost as stiff and threatening as the prick that was starting to emerge from Gerald's pajamas. This, too, was a mystery to Donna.
"Just take it easy, take it easy," Gerald intoned. "Relax and let yourself feel it. You have such a fucking beautiful cunt. I want to cum all over you, feel my prick explode inside you. You want it, too, don't you Donna?"
There was no need for Donna to frame an answer to her brother's rhetorical questions. Her cunt had begun to relax of its own accord, embarrassingly wet now, quivering palpably around the finger that was stimulating it so well. All sensation had been localized in that mysterious cavity. It was as if her whole body had been drawn into the hungry maw of her virgin fuck hole.
"Touch me," Gerald insisted. "Go on, you know just what I want you to do. Take it in your hand and make me feel good." Gerald shifted his weight again, practically forcing his stiff cock into his sister's inexperienced hand. He felt like he could cum on the spot as he had done so many times with other girls. Only this time it was different. There was nothing frightening about Donna. She was his sister, flesh of his flesh, a woman who understood him and whom he could trust completely.
Still, a pang of uncontrollable lust passed through the lad's body as he felt his sister's fingers making first contact with his throbbing meat. Her nails scratched the swollen head of his rod but added to Gerald's lust. There was little she could have done to turn him off at that late stage of the game.
Donna felt a brief moment of shame as she weighed her brother's cock in her soft hands. The thing seemed to be a good seven inches long and three or four inches thick, lined with hard veins and thicker at the base and head than in the middle. It was strange to feel the heavy burden palpitating in her hands, but Gerald liked what she was doing. For once in her life Donna didn't have to feel inferior to other women.
It took only a few minutes for Donna to learn how to please her lover. She coiled her soft fingers around the center of the thick shaft and then began to pull the loose skin back and forth over the swollen crown. Each stroke increased the rate and intensity of Gerald's breathing, to the point where Donna was able to ignore for a moment the storm of passion that was continuing to wreak havoc in her own luscious young body.
"It's so big and hard, I'm scared of it," Donna murmured a few seconds later, as much to herself as to Gerald. "You wouldn't do anything to hurt me, would you?"
Gerald ignored his sister's frightened question, just as she had done to him a few minutes before. He had the girl just where he wanted her, and there was no need for discussion. His finger had now penetrated her wet pussy to the last knuckle and it was a lot easier to see her now that his eyes were used to the night light.
His sister was incredibly beautiful, her tits jutting out provocatively from her slender birdlike torso, her soft ass grinding into the mattress beneath her. Everything about the girl was soft and young and innocent. Everything but her face which had transformed into a mask of naked lust. Yes, Gerald was going to get just what he wanted from the hotpants little sexpot.
Reluctantly, Gerald pulled his prick away from his sister's clenching hand. It was time to explore her pussy more closely, to get his tongue into that redolent fuck box. His mouth watered at the thought but Gerald was experienced enough to take his time and avoid scaring his innocent little sister.
Soon Gerald was lying with his head between Donna's thighs. The smell of her cunt was enough to drive him wild with sexual need. Her twat writhed open before Gerald's staring eyes, the freshest and most pungent thing he had ever experienced. His tongue protruded from his mouth, and then Gerald was ready to take the all-important next step. Using one hand to part the girl's soft pink labia, Gerald soon was able to work his tongue into the lovely little crevice. First he brushed his lingual organ against Donna's clitoris, more by accident than by design. It was surprising to feel the girl writhe and quiver before he was inside her, a fact that Gerald knew to file for future reference.
But soon the enterprising lad had worked his tongue all the way into his sister's twat. Her taste was unbelievable, pure, clean and intolerably stimulating. Gerald left his tongue in the fissure for a few seconds more and then started to rotate it slowly, knowing that it was too late for Donna to resist.
He reached up again and began to fondle the girl's tits, not bothering to be gentle this time around. Her nipples were red in the semi-darkness, outlined clearly against the snowy whiteness of her boobs. Donna's eyes were closed and it was impossible to know what the girl was thinking and feeling as he continued to work her pussy over with his greedy, insatiable tongue.
By that point Donna had given up trying to control or even understand the things that were happening between herself and her handsome brother. She had dreamed of moments like this but had never been able to visualize that actual details of sex. The reality of her passion was far better than anything the young temptress had ever dared to imagine.
"Yes, keep doing that with your tongue," she shouted aloud, shocked by her own boldness. "I can't tell you what it's doing to me. I never knew it could be like this. Stick it in further. Come on, Gerald, do it just like you were before. Aaahhh, Goddddd!"
Gerald felt a surge of power after hearing his sister's impassioned request. He forced his tongue deeper into Donna's dripping quim and then stopped short, feeling her healthy young vaginal muscles contracting around him. She was hot to trot, all right, ready to be brought to the first orgasm of her young life.
