Chapter 4 The Best of Both Worlds

It was as the pleasant sensations began to truly fade and her body returned to normal a few moments later, that Gaz realized Dib had not cum. She had never seen a boy's orgasm but she knew they spurted something from their dicks.

She raised herself on one elbow and looked at Dib's still erect penis as it hung to one side of his groin. She grabbed and felt her own saliva beginning to dry on his skin. She pulled the organ towards herself, pointing the head at her face.

She stared as it for a moment, before shrugging and leaning forward once again to pop the purple helmet into her open maw. With both her hands now free, she began to play with his ball sack once again. She moved her lips up and down his shaft, making slurping sounds as she went, while her other hand occasionally pumped his shaft.

She heard Dib moan and then sigh in sexual pleasure. Apparently she was doing this right.

Gaz suckled at the rubbery gland in her mouth. The sensation of slurping at the bulbous knob was almost exactly like sucking on a hot-dog. The taste was different though; mostly the bland flavor of skin, but occasionally she got a dribble of his pre-cum on her tongue.

She still felt horny; the desire for more sexual stimulation and play was strong, but her actual arousal had diminished to a low warmth. It would be a bit of time before she could diddle herself to orgasm again. After a couple of moments of blowing her brother, Gaz became slightly bored. Still, she kept at it. It excited her a little, making her tingle at the perverseness of the act, plus the sense of domination and power over him.

Her eyes wandered around Dib's room, until she suddenly spied her discarded Game Slave 2 laying on the floor. The urge play videogames welled up within her once again; to hold her beloved little portable game system in her grasp. Gaz's hands kept working at Dib's genitals, while she slide him in and out of her mouth. Her hands were occupied, but her fingers practically twitched with the urge to caress something else.

Abruptly, she sat up, which made Dib's penis slip out of her mouth with a wet *pop.* She climbed over Dib's legs and slide to the floor. Plucking up her Game Slave 2, she pressed the power button and began another game.

Behind her, Dib made noise. “Ghaahz?” he called, concern audible in his voice. He must have felt her get off of the bed.

Gaz spared him a glance for a few seconds, before she reached over and yanked off his blindfold. Dib blinked in the sudden flood of light into his eyes. As his eyes adjusted and his vision cleared, he saw Gaz standing next to his bed. After Gaz was sure he could see her, she hooked her right thumb into the waistband of her panties and pulled the thoroughly soaked underwear down to her ankles.

Gaz grinned as she watched her brother's eyes bulge in response. He tried to say something around his gag, which thoroughly garbled it, but she ignored him. Her hand returned to her Game Slave and she resumed playing. Deftly stepping out of her panties, she sat her petite rump on the edge of Dib's bed. She scoot back until the skin of her butt touched his thigh, which made Dib shiver. Then, while still playing her game, she crawled over his middle, opening her legs and giving him a good look between her thighs.

The familiar sounds of the Game slave 2 could be heard as Gaz finally settled herself down between his spread legs. Dib began to protest around his gag once more, but Gaz still paid him now mind. Actually, she kind of liked the sound of his helpless noise.

Gaz scooted backward until she was laying with her belly on his sheets and her young chest pressed into his groin. Dib squirmed a little as he felt the soft bumps on her chest rubbing and grinding into his still very erect penis. At last, Gaz put both her elbows on his inner thighs. He felt her press down, her slim weight pushing his already spread legs further apart.

She propped her torso up on her elbows, leaving her head hovering directly over her brother's throbbing organ, which pointed upwards at her mouth. His sister's elevated position gave Dib an excellent view of her budding chest, resplendent with her pale pink nipples and areolas.

She moved her hands up from his groin to his belly, bringing her wrists to rest on his stomach. She still held the Game Slave in one hand. Gaz sighed and suddenly sank her head lower, until her lips touched his the tip of erection.

Dib gasped Gaz slurped the end of his cock past her lips and into her mouth. Then he felt more of his shaft disappear into her hot wet mouth; felt her lips gently working at his dick as she sucked him it. Gaz spread her elbows and lowered her head, driving the rest of “little Dib” into her mouth until finally her nose bumped into the skin of groin.

Gaz sighed again, this time letting the air escape around Dib's engulfed cock and causing him to jerk at the feel of it. Her eyes were focused on the Game Slave in her hands, which still emitted sound. She began to work the plastic buttons as she started a new game.

As she played, Gaz sucked with her mouth, and worked his shaft with her lips, tongue and jaw. She even slowly moved her head up and down, slurping the length of him in and out from between her lips.

Dib struggled wildly for a moment, making frantic noises of shocked protest. Of course, his efforts were futile. Dib could not move any more than two inches in any direction. He only succeeded in shaking himself and Gaz a little.

Again Gaz took no notice. She continued to suck away on him. She kicked her legs as she relished playing her beloved Game Slave 2 once more, while mildly tormenting her brother and slowly arousing herself. She sucked on him quite merrily and played her videogame as if this was the most normal thing in the world.

Eventually Dib gave up, overwhelmed by the feeling of his sister's mouth around his penis. As he watched her blowing him, he tried to fight the slowly rising orgasm he felt in his balls. A few more minutes like this and he was going to blow it.

Gaz's moved slowly up and down his shaft, but her lips and tongue worked with greater intensity. Only a few minutes ticked by and already Gaz was well into her new game. In her excitement she unconsciously increased the strength of her suction. She was only half paying attention to her brother's hard throbbing dick in her mouth. The majority of her focus, as always it seemed, was on her video game.

Gaz had two pleasures in life. Video games, and food. She combined them both whenever she could, and right then her mouth was unconsciously doing its very best to swallow whatever tasty morsel she was feeding it.

She forced her tongue into the crevices between where the shaft met the crown's base, bathing the tight rubbery skin in her saliva. A moment later she twirled her tongue over the knobby head, sucking powerfully as she did. She tasted more of his salty pre-cum. It was... pleasing to her tongue. She let out a “mmm” sound around Dib's cock. This sent extremely pleasure vibrations back up his shaft, making it “jump” in her mouth.

The spasm from her brother's captured organ surprised Gaz, nearly making her lose concentration on her video game. But she maintained control. It was like adding a little more challenge to playing videogames.

She continued to lick and suckle him, beginning to moan and hum around his pulsing shaft more frequently just to torment him. This, of course, produced delightful results and she tasted more dribbles of fluid from end of his shaft in her mouth. She slurped it up, savoring the liquid pleasure she was extracting from her helpless brother. Each little drop she tasted made her think about the spunk she was going to force him to eject into her mouth, whether he wanted to or not, and that thought made her loins burn with renewed excitement.

A few minutes later, Gaz only partially heard Dib's warning cries, her concentration being elsewhere. She did notice when she suddenly felt his cock in her mouth engorge itself to rigidity on her tongue. Then his cock began to spasm while shooting stream after stream of thick salty cum into her mouth and down her throat.

Gaz paused her game and sucked and swallowed around Dib's organ. She watched her brother's face while she worked him over with her mouth, drawing the rest of his orgasm from him. She looked up and made eye contact with him while his eyes rolled back and his head bent to one side. Occasionally his gaze flickered back to her pretty face, watching her watched him, all the while she continued to suck feverishly at his ejaculating penis and swallowing his load.

Even though his climax had surprised her, it was short lived. After four or five good loads, his orgasm began to fade, the pulsating throbs becoming weaker until his dick was only half-erect in her mouth.

Gaz grinned, slurping at his deflating tool. She watched as Dib's eyes finish their ramdon rolling and he blinked them back into focus on her. She still had her lips wrapped possessively around the tip of his penis, her cheeks puckering as she kept sucking on him.

Dib moaned in pleasure at his orgasmic release and stared back into his sister's face.

Once satisfied she had taken all he had to offer, Gaz relaxed herself. He had come faster than she expected, but even so she was a little sore from her position. She put down her Game Slave, and finally let Dib's captured member pop free from her lips. She leaned forward into a full body stretch, pressing her face into Dib's stomach as she arched her back.

Gaz felt warm and excited. The sheer debauchery of guzzling her brother's forced orgasm, mingled with the high of totally dominating him, made her shiver. While still laying on top of Dib, she reached down a free hand and stroked her moist slit, tracing a finger long the ridge of her swollen labia.

The action sent a burst of warmth through her thighs. She wanted to masturbate again. But even as her finger traced her nether lips for a second time, Gaz's eyes fell on the Game Slave 2 cradled in her other hand. She stared hard at the portable gaming system.

Dib stirred underneath her, disrupting her thoughts. Gaz turned to look directly into his face. He stared back at her and said something around his gag, but it was unintelligible. Gaz stayed bent low over Dib's middle, and looked at him a little longer, thinking what to do.

When Dib's penis gently poked itself into her budding breasts, she raised herself and looked down. Dib was still half-erect, still hard. As she saw his slowly bobbing penis pointing at her, she grinned. Turning back to face Dib, her grin widened.

She propped herself up and then crawled up Dib's body, until her face was inches from his. Dib felt sister's hot breath on his face. She reaches up to take hold of his head with her hands, one gripping the strap of his gag. Dib's heart rose in happiness. She was going to remove the gag!

But instead of releasing the binding straps, Dib was shocked when Gaz leaned forward and he felt her tongue touch his lips and mouth. He jerked and squirmed in surprise and shock, but Gaz held him firmly. With his sister's strong grip and his restrictive bondage, Dib could not pull away.

Gaz's tongue touched him again and this time he felt it lick his lips. Her tongue traced over his lips, which were forcibly spread wide by the rubber ball gag. She licked all the corners of his mouth and he felt her lapping up the drool at that was running down his jawline. She lapped at his lips and then followed the trail of saliva under his jaw and down his throat, gently slurping up the fallen moisture.

After she was done cleaning up all of his mess, she kissed his ball gag mouth. Then gently slid off his bound body, the fingers of her hands trailing down the center of his chest as she moved away. Dib was stunned.

Standing beside the bed, Gaz stretched again, and then reached down to unlock the chains around Dib's ankles. His heart rose in happy hope. A moment later, Gaz released the chains around his wrists, freeing his arms.

Dib flexed his freed limbs and smiled around his gag. He was glad she was finally setting him free. As he attempted to sit up, he was jerked back by the collar and chain around his neck.

He reached up to touch this last chain which prevented him from leaving his bed. His fingers noted the presence of a small padlock. Knowing now he could not free himself, he turned expectantly to his sister, waiting for her to fully free him from his bondage.

Gaz stepped forward, but instead of presenting a key to the chain, she placed both hands on his chest and pushed him back onto the bed. He gave way in surprise, letting himself be laid flat back onto the sheets. Next Gaz climbed back onto the bed and on top of him. This made Dib protest and reach up to try to stop her.

She grabed hold of his hands with her own. He searched her eyes for meaning. She stared back determinedly.

“Listen Dib.” she says, glaring at him. “I'm going to play my Game Slave while I have sex with you. Make it good.”

“Bhaat Ghaahz! Whee chaahn't--” Dib began to protest, but Gaz quickly cuts him off.

Gaz reached forward and roughly grabbed her brother by his naked shoulders. She brought her face to within an inch of his. Breathing heavily, flushed with the exhilaration of it, Gaz ordered, “Fuck me now Dib, or else. Fuck me now and fuck me good, or I'm **not** going to unchain your collar. Got it!?”

The intensity of his sister's stare, and the fear of much worse than being left chained up, made Dib gulp. He slowly nodded as he stared into her piercing eyes so close to his own.

Gaz let go of him and leaned back. With her rump sitting on his groin, she turned herself around until her back was facing him, assuming something like the reverse cowgirl position. She used her knees to raise herself above him. With her free hand, she reached down and grabbed his semi-erect penis. The threat of violence must have deflated him a little, but she gave him a few good pumps with her hand and little Dib's head swelled back to its normal large size.

With Dib erect once more, Gaz pointed him upwards towards her dripping slit. She rubbed his purple cock head back and forth over her swollen labia, moist with arousal and hot from the lust she felt. Droplets of her pussy juice leaked onto his crown and down his shaft. With her other hand she began to diddle her once again erect clitoris.

If Dib was not erect before, he was now hard as stone. Watching his sister handle his meat and rub his little head against her swollen dripping opening, feeling the heat from her genitals as they brushed against his, was enough to send his loins into over drive.

After taking the time to make sure that she was sufficiently aroused, Gaz positioned the tip of his penis upward. She slipped it just inside her nether lips. Then keeping one hand on his shaft to guide it, she slowly lowered herself down bit by bit, plunging his shaft gradually into her depths.

It was all Dib could do to keep from thrusting his hips as his penis was wrapped all around with tight wet feminine flesh. The feeling of his sister's tight little pussy totally engulfing his swollen dick was indescribable.

When Gaz had almost finished lowering herself back onto his lap, Dib's hips, overwhelmed by the feel of her tight pink tunnel, gave an little involuntary thrust up. The movement made Gaz's small body bounce a little. She grunted but said nothing.

After setting herself down, she reached out and picked up the Game Slave from the bed sheets. She pressed start and re-engaged her game. Meanwhile, using her legs for leverage she slowly raised herself up her brother's shaft. Then she promptly plunged herself back down, thrusting him upward into herself. She grunted in exertion and pleasure.

Seeing that she was ready, Dib tried a slow thrust upward into Gaz. She immediately responded by raising up his shaft and then come back down to meet this second thrust. Dib began a slow thrusting upward with his hips, driving his little pecker in and out of her gripping hot snatch. Every time Dib drew back for a thrust, she pushed herself up a little to add to the withdrawl, before plunging herself down onto his member in his rising thrust upward, spearing her pulsing depths with his tool.

Gaz's focus never wavered from her game, but her hips seemed to keep working without her thought, slowly fucking herself on her brother's dick. Each thrust felt good to Gaz, sending ripples of pleasure up into her belly. The slow rocking motion of their bodies pounding each other filled the room with a slap... slap... slap of flesh colliding. The sound of their slick genitalia interlocking together could also be heard.

Gaz was grunting now with every other thrust, feeling her arousal slowly building. Without meaning to her thrusts had risen slightly in tempo over time. She was panting through her mouth frequently now. Sweat was beginning to glisten on her pale white skin.

Suddenly she felt Dib's hand caress her backside, fondling her cheeks as she slammed her bum down into his groin. At his touch on her petite ass, Gaz ground her butt into his crotch, sending jolts of pleasure shooting into herself as Dib's penis poked this way and that inside her, and his fleshed rubbed against her engorged clit.

As she rose again off Dib, she felt his hand guiding her, and she let him as she rose up and them slammed down onto his shaft, grinding him again. Dib ground back this time, making his embedded cock scrape against her delicate pink lining. Gaz let out a small yelp as his cock touched a particularly sensitive nerve.

They kept thrusting and grinding, Dib using his grip on her waist and bum cheeks to guide his thrusts with more strength and motion. The heat in Gaz was starting to really build. Every now and then, she had trouble keeping focused on the game. Her body now shined with sweat, her skin slick with it on her legs and thigh, especially where her flesh met her brothers. Dib was sweating too.

At one instance, when trying to concentrate on her game, Gaz found herself muttering, “More. A little more.”

Dib heard this and obliged. Gripping his sister by her waist, he scooted himself back on the bed, while keeping her sitting in his lap. Now he had a little more slack on his collar chain. Then he leaned forward and reached his hands up to caress her erect nipples. He gentle massaged her areolas and rubbed her teats between his thumb and forefinger.

Gaz gasped at this sudden unexpected pleasure. Then she gritted her teeth and frantically continued working on her game. Dib resumed his thrusting, but Gaz was slower to join him. For a while, he essentially just bounced her on his lap, the sound of skin slapping increasing rapidly until it was a regular beat.

Suddenly, Gaz exclaimed, "Uhh, uhh, yeah, oh YEAHHH! Fuck yeah, I just beat the mini-boss!"

Dib just sighed around his gag, knowing it was futile to try to say anything. He just tweaked her nipples and grounded his groin into her extra hard to show his support. Gaz grunted and gritted her teeth against the distracting pleasure. Her pussy was already threatening to start spasming around Dib's very effective little guy and Gaz was fighting to finish her game first.

Sweat poured down Gaz's face as her legs jerked and thrust her little body against her brother's without her will. The pleasure was welling up in her groin, pooling into a hot mass that threatened to explode out from inside herself. Dib's hard cock felt so good thrusting inside her and his fingers felt great as they played with her budding breasts and nipples.

But she held herself back, not letting the feelings overrun her just yet. She had to win first. Her fingers trembled as her legs quivered, her climax threatening to burst. She was so close. She willed herself to hold out... for just... a few seconds longer.

At last she punched the attack button for the final time and watched as the main boss crumbled on screen. Gaz grinned widely, panting hard with exhilaration and feeling. She relaxed her grip on the Game Slave and suddenly thrust back into Dib as hard as she could. For a several frantic seconds she slid forward and then thrust back again and again, rocking the bed with her motion as the bedframe creaked in complaint.

And then, Gaz came. Gaz's eyes rolled back into her head and she clenched her teeth, biting her lower lip. Her insides tightened into a knot as her pussy seemed to compress in on itself. Dib felt the muscles in her body tense and felt her snatch suddenly grip him like a small vice. Then Gaz's body was rocked by spasms as the dam of pleasure inside her broke. Her pussy clamped and released and clamped and released Dib's member as he kept thrusting into her as she rode him through her orgasm.

Gaz's mind clouded and her body seemed to melt, suffused with a sudden pervasive warmth from within. As the heat spread, Gaz's body relaxed and the stiffness of her spasms faded and slowly died away. She sat limply on her brother's groin as se still pounded away at her. If not for his arms around her chest to keep her balance, she might have let her body slip off him.

But Dib held her up, still rubbing and now lightly tugging on her nipples. He kept thrusting, even though Gaz was no longer returning his motions.

Gaz sat as her body was rocked by her brother's continued thrusts, his actions churning her afterglow into a longer life than was normal. She let her body and mind relax, just absorbing the sensations of it all.

Eventually, a few minutes later, Dib's body tensed beneath her and she felt him slow him thrusting. She turned to look and saw his face was contorted in pleasure.

“Ghonnah... Chummhf!” he managed around his gag.

He shifted his legs, and turned his middle, awkwardly dumping Gaz onto her side. He pulled his hips away, as if to slide his penis out of her. Gaz abruptly reached behind him and grabbed his ass cheeks. Pushing him forward, she thrust his groin back into her behind, while at the same time thrusting her hips back against him.

“Keep going.” she ordered, roughly holding his body close against her.

Dib did not protest, because only a few second later, his cock exploded into life for the second time, emptying its contents into Gaz's depths. Dib's hips thrust powerfully with each spasm, as he gripped her waist and thighs. He rocked her small body, driving into her as deep as could while fighting the paralyzing pleasure that clutched at him.

In a half moment, his orgasm was over. He had pumped Gaz full of his cream and they both knew it.
