And, when Robby pushed a little more forcefully one time, and the head of his dick slipped through her tight sphincter, it happened so quickly that neither teen was prepared for it.
Suddenly ... quite suddenly ... The head of Robby's prick was surrounded by tight, hot, slippery pussy flesh, and Debbie's pussy lips complained as they were stretched farther than they ever had been before. That little place that gave her twinges occasionally gave a yelp of distress as what was left of her cherry was shredded and the tatters pushed out of the way. That his prick didn't go deeper was only because, as Robby had pushed in the past, he pushed only so hard ... only hard enough to keep firm contact with his sister's pussy lips and mound.
"OH! Owww," moaned Debbie, as she was penetrated for the first time in her life by anything bigger than a finger.
Robby froze, hearing the distress in her voice. He also understood something new had happened, and had a pretty good idea of what that was. He left his knob securely locked in her, as her pussy lips closed tightly just below the neck under that head.
"You okay?" he asked, breathlessly.
"It stings a little," she said, her voice not quite whining. "It's stretching me."
"You want me to take it out?" he asked. He gave a tentative pull, just enough to feel that he was firmly stuck in her, and that if he pulled out it would stretch her even more ... or again, as the case was.
"No," she said. "Not yet. It doesn't feel so bad now. I think I'm stretching or something."
Robby was in a quandary. He knew enough about his penis that he knew it was bigger around in both directions from where it was so firmly gripped. It didn't matter if he went further in, or pulled back. The results would be the same. It would hurt her.
"Maybe I'd better take it out," he panted. It felt wonderful right where it was, but he didn't want to cause his sister pain.
"No, it's not so bad now. Just don't move for a minute, okay?" She was beginning to pant too.
"I have to do something," he said. "My back is starting to hurt."
"Suck my nipples some more," she said. She wanted to move her hips, but was afraid to. This was a whole new feeling. The top of his shaft, right behind the head, was in contact with her button, and she just knew that if she thrust upward that contact would increase. She wanted that contact to increase, but was also afraid the pain would come back.
Her mistake was that, whenever he sucked her nipples, her body did what it wanted to. She had never thought about the fact that as he sucked, her hips moved. And this time, when he sucked, and her hips moved, it achieved what she'd wanted to feel. Her pussy climbed the shaft of his penis about two inches and she was stretched again.
There were competing feelings. Her clit shouted, "Yes!" while her poor stretched pussy lips wailed, "Noooooo" The slight tear that was all that was left of her hymen squealed and pumped a few drops of bright red blood out of that tear as the bottom of his shaft scraped along there, spreading that blood deeper into her channel. Her nipple, which was being sucked into her brother's mouth and bitten gently, added its scream of, "Oh fuck yes!" to the mix, and that was what overpowered the complaining parts.
Roby felt more of his prick enveloped by wet heat, but by then it was too late to do anything about it. He let her nipple pop out of his mouth and looked at her face. Her mouth was stretched into a grimace, her eyes tightly closed. She looked like she was in pain. He automatically started to pull back, pushing with his arms. He did it so quickly that it made a sucking popping sound as his prick was jerked out of her pussy.
Her eyes snapped open and her grimace went to a round shape.
"Nooooo don't take it out," she complained.
But it was too late. It was already out. They both looked down to see his hard cock suspended over her pussy. There was a sheen of moisture that went a third of the way up the shaft. It glistened like a coat of paint on his cock, with just the faintest tinge of pink to it.
"It was hurting you," he said, pushing up to sit on his calves and give his back muscles some relief. The sheet slid off his shoulders and fell on his heels. His sister's naked body lay spread eagle before him.
"It's cold!" she said, reaching for him. "Come back." She sat up and grasped his shoulders, pulling at him. "And it felt good too."
Robby lay down beside her, pulling her on her side, to cover them with the sheet again and hug her. He kissed her lips.
"I don't want to hurt you," he said as she snuggled against him, trying to put as much of her skin against his warmth as possible.
"I told you it felt good too," she said. "It was starting to feel even better. Put it back in," she demanded.
"We can't," said Robby. "I told you. You could get pregnant."
"You can take it out when you squirt," she countered. Her hips were pushing against his penis, which was still hard.
"You really want me to?" he asked, unable to believe that she wanted something that hurt.
"Put it back in," she repeated.
It was, in one sense, mere exploration, just as they had done before. But feeling that penis in her vagina had awakened something in Debbie that had been peacefully asleep before now. She had known, on an intellectual level, what intercourse was, but had never really thought to try it. It was a little like seeing a food one had never tried, and thinking that it might be good ... that it could be good ... but never actually feeling like you wanted to put it in your mouth.
All that had changed as she felt the pain of, in a purely sexual sense, becoming a woman. Now the thing that had awakened deep in her brain had tasted that strange food and the sensations were both bitter and sweet. As if it had taste buds, her pussy wanted another sampling of that new delicacy ... wanted a mouth full of that strange taste ... so she could experience it to the fullest.
Therefore, when she pulled her brother back on top of her, and he tentatively pushed the crown of his iron hard penis between her pussy lips, she unthinkingly thrust up at him.
To take the food analogy just a bit further ... she bit off a little more than she could comfortably chew.
Robby felt her pushing up at him and his natural response was to push back. They'd been doing that for a long time - pushing their loins at each other - but this time his prick, already lubricated with her slick juices, pushed into her like a hand fitting into a too-tight glove. The stretching sensation started again at her pussy's mouth, as their lips went suddenly white and thin as they tried to expand around not only the head, but the shaft that followed. Then her tight pussy clenched as the sensitive tissues were forced apart.
Her immediate response was to take in a big breath to shout that it hurt and, at the same time, to drop her bottom back to the bed in an attempt to get away from the thing that was stretching her so cruelly.
Ironically, it was her body's attempt to get away from the sk$$$$$ng spear that dropped her clit into full contact with the top of his shaft as it went deep in her. By then there were only two or three inches of shaft left outside her body to scrape along her super-sensitive bud, but those two or three inches made all the difference in the world. The fact that Robby's brain insisted on continuing to push once he was fully seated in her sex also caused his pubic bone to smash her clit as if it were trying to drive the little organ back into its protective sheath.
Her clitoris wasn't about to surrender, however. It fought back by engorging even more, becoming rubbery-hard as it was over stimulated by pressure. It sent screaming signals along neural pathways, calling for relief.
The result was, that by the time her complaint of pain reached her mouth, with its jaws clamped firmly closed in a wide grimace, it turned from an expression of pain to a groan of satisfaction as her body got exactly what it had asked for ... a pussy just stuffed to overflowing with a nice, long, hard male organ and the beginnings of a physical response called an orgasm rushing toward her like an ambulance hurrying to give aid.
Robby, meanwhile, was caught on the horns of another dilemma. As his penis was surrounded by hot pussy flesh that hugged him like a sexual bear-hug, he knew immediately that if he moved, even an inch, cum would boil out of the tip of his prick like steaming water gushed from Old Faithful at Yellowstone National Park. It was partly that feeling that caused him to keep pushing, to stay as fully seated in his sister as it was possible for him to be. He felt panic, joy and ecstasy all at the same time. He was quite literally overwhelmed with sensations and feelings.
Debbie, as her clit fought for its life, felt something else, deeper inside her. It was another pain as the tip of her brother's prick, which had defeated her outer portal, found another doorway and tried to force its way through that one as well. Her virgin cervix refused to open, at least open enough to allow that invading monster to push into the womb those gates guarded, and that caused pain too. This pain was of a deeper type, not sharp and stinging, but a dull ache that was something like the ache in muscles that is eased by a good, long, body-bending stretch.
Her pussy muscles tried to adjust and do that stretching. What happened would probably have been called a spasm by a Doctor, as her abused muscles moved and shifted erratically, in almost a rippling motion. Her screaming clitty's message flashed along a nervous system that was overloaded with sensations. Her body's response to this overload of stimulation was to act a little bit like a circuit breaker. Except, in this case, when the switch kicked to "standby", it energized another circuit that her orgasm flowed along at something close to light speed. Most of her body went rigid, muscles locked temporarily in that "stand by" mode, as the spasms took all the body's resources and centered them on her pussy.
Robby too was dealing with an overload as Debbie's twitching cervical lips tried to close, then open, then close again, almost massaging the sensitive tip of his penis. With a helpless groan, Robby's body did exactly what it was designed to do. Automatic reflexes kicked in and his body expelled the fluid that would sooth the electric shocks that were torturing his penis. Creamy fluid filled the tiny tube that was the primary complainant in his body at the moment and, having no place else to go once it had served that purpose, jetted out of the tip of his cock, splashing all over Debbie's tight cervical mouth. Then, not satisfied that it had completely soothed his penis, his body served up four more helpings of that warm cream, to ensure that the stimulation was dealt with.
Debbie's cervix, told by some nervous communication involved with her orgasm, finally relaxed, the lips loosening fractionally and dipping outward to flow around the blunt thing trying to batter its way past them. Three soothing warm jets of fluid then splattered into the soft dark cave deep inside her body that was made to welcome that fluid.
In the space of some twenty or thirty seconds, a million nervous impulses did what they were designed to do and did it flawlessly. And, in the space of only four or five seconds, even more millions of healthy, viable sperm cells were transported from one human being into another.
A miracle of nature had taken place in the space of a few breaths, and even fewer blinks of an eye.
Debbie felt, on some level, the rush of wet warmth that flowed into her body from her brother's penis. She was instantly addicted to the feeling. She was addicted before she had any conscious thought of what was really happening, or the consequences of those actions. On a purely metaphysical plane of existence, she knew she had found the thing that made her the happiest she had ever been thus far in her life.
Robby's experience was a bit more tortured. He knew exactly what was happening before it actually happened. He knew he was about to cum in his sister, and that there was nothing in the world he could do about it. He knew that even if he jerked his prick out of her, he couldn't do it before he spermed her pussy. In his mind's eye he knew he was going to fill his sister's belly with life and the electrons bouncing around in his brain visualized his emission as tiny full-formed fetuses being injected into her womb, where the thousands he saw would grow and burst from her body, destroying her like some alien plague.
Even as he felt the explosion of ecstasy that went along with his orgasm, he felt the misery of having ruined his sister's life. He berated himself, admitting that he knew better than to let her bully him into doing this thing. At the same time he felt his body insist that he stay right where he was until the last feeble clench in his groin expelled the last few straggling sperm cells from his body into hers.
Then, feeling completely miserable, he collapsed on top of her.
They lay there gasping for breath for a few minutes. Robby rehearsed in his mind the various ways he could apologize to his sister, who would now probably hate him for the rest of her life. He felt her hands come to his waist, and expected her to push as her angry outbursts began.
Instead her hands stroked along his sides, and up onto his back, and then down to his buttocks.
"Oh thank you Robby" she sighed. "Thank you so much."
Robby was stuck speechless.
Debbie squeezed him with her arms. "I completely understand why Mommy wants to do that now."
Robby found the energy to push with his arms, so he could look at his sister's face. Perhaps the 'alien invasion' had altered her already.
"I fucked you," he said. It was hard to tell if that was a question or statement. The words sounded harsh in his own mind, but that was how he characterized what had happened.
She just looked up at him adoringly, her eyes big and liquid brown suddenly.
"I wasn't supposed to do that," he croaked.
Debbie's hands left his sides, where they had come to rest. She grasped his head gently and pulled him down for a kiss. When it was done she let him go.
"When do you think you'll be able to fuck me again?" she asked. "You didn't go nearly as long as Mommy and Uncle Robert go."
Robby looked at her incredulously. He tried to roll off of her, but she gripped him and rolled with him until they were again lying side by side.
It took half an hour, but they talked about what had happened, and how each of them felt about it. Robby learned that, not counting the dangerous nature of the transfer of body fluids, he had done nothing but please his sister. She had already forgotten the pain and discomfort she had felt initially. She didn't care about the fact that he might have made her pregnant. She would care later, but she was still in the grip of the chemicals a woman's body produces during an orgasm that are designed specifically to encourage her to lie there afterward and let all that nice sperm soak in completely before she gets up.
In the end he insisted that, if they did this again, they had to do it only at times when she was unlikely to be fertile and that they had to try to find some way to acquire some rubbers. She, on the other hand, insisted that she would be extremely unhappy if he tried to keep her from enjoying this new thing they had found together, and that it would happen again or he'd be sorry.
While it sounds like they argued, it wasn't really like that at all. It was more of a situation where each pleaded his or her case about what they wanted the future to be like. As with most teens, they couldn't see very far into the future, and their plans were, for the most part, short term. It was impossible, lying there in the afterglow of sex, even if it wasn't 'good sex' in a classical sense, not to give each other little loving touches and kisses.
Once they had said what they felt the need to say, they kissed some more. It was comfortable lying there together. Their speech got less and less focused and, eventually, they drifted off to sleep in each other's arms.
That's how Ramona found them when she broke her routine and came home for lunch for only the third or forth time since she'd taken her job at the bank.
