Once the elevator reached ground level, Gaz got out and said, "I can't believe I'm an actual sex slave now. I'll be having sex with Master's delicious meaty cock, bred by his tasty cum, and used as he sees fit. I'm so happy." She jumped a bit when she saw Gir watching TV to her left. He didn't hear what Gaz said, but Gaz knew someday Gir would see her naked because of the house rule. Maybe even while Zim was training her or just having sex for fun. So might as well see her naked now.
Gaz walked over to Gir but didn't stand in front of the TV. "Gir, could you tell me where the Master's room is, please?" She asked with a smirk. Gir looked a bit to his right and saw Gaz naked and wearing her sex slave collar. Her nipples forever erect and her pussy forever wet with juices stopping just at mid-thigh. Gir pointed to the room upstairs then continued looking at the TV.
"You're Zim's sex slave now?" The small robot asked. Zim must have told Gir about this, or Gir figured out why Gaz looked like a slut. Gaz didn't care either way.
"Yes, I am," Gaz replied. Gir smiled. "So you'll be seeing me coming around when Master wants to train me or just have fun sex." Still smiling, Gir said,
"Be what makes you happy."
"I am, Gir. I really am," Gaz replied. Gir continued with his cartoon marathon while Gaz walked upstairs and finally walked towards Zim's room. As she walked in, Gaz saw a beautiful pink heart-shaped bed with a pink curtain around it. "Has Zim had this bed the entire time he's been on Earth? Has he been waiting for this day or did he just put this here for me?" She would have to ask when he comes up. Gaz slightly bent over the bed, touching the soft cloud-like mattress. "Oh my god"! These sheets are so comfortable. I can't wait to be fucked and cuddle with Zim in it," She smirked almost in a giddy way. Gaz walked over to Zim's bathroom. The bedroom was bare and so was the bathroom. The bare essentials were the only thing in there. Gaz saw Zim used the same kind of mouthwash to get rid of tastes in the mouth. The huge ass slut could still taste the cum she swallowed. Gaz thought Zim wouldn't mind if she used the mouthwash. She wanted the kissing to be special on this special day.
Gaz went back to the bedroom and sat on the edge of the bed, waiting eagerly for her Master. Ten minutes passed before Zim walked in with a green color vial in hand. Gaz immediately stared at her Master's big hefty cock, mentally drooling like her pussy was. "What is that vial going to do?" She asked.
"When I told you that you will remain the way you are after taking the red vial, it included your hymen being repaired. So the green vial takes negates that from happening. Your body will never go raw from sex, and you can cum and keep cumming no matter what. At any point you feel physically exhausted from sex as normal humans do, this vial will allow your body to still be able to cum," Zim said.
Zim gave Gaz the vial. She drank it and spread her legs for Zim to see. "I'm ready, master," She said surly. Zim flashed a grin, hungrily glaring into his new submissive slave. He got on his knees in front of her pussy and began licking her. Zim's tongue began to swirl in Gaz's inside. "Ohhhhh," She moaned shamelessly. "Your tongue is incredible, master." Gaz proved her point by her wobbly legs. She felt back onto the bed, but Zim kept licking her out. His long alien tongue drove deep into her tasty cunt. Gaz squealed. Her eyes rolling back as the pleasure raced through her like a shot of heroin. Within a minute, her body convulsed as she came. Gaz squirted at Zim's face as he continued sucking her out.
After her climax, Zim told her to move up on the bed. The slave did, spreading her legs wide open for Zim. The alien got onto the bed and lean over Gaz. His left hand on Gaz's right shoulder. He used his right hand to aim his dick firmly against the entrance of her honeypot. He placed his right hand on Gaz's left shoulder and slowly inserted his dick inside. He moved carefully, grunting at the tight vice as Gaz moaned more, "It's so big," She softly moaned. There would be time for her to cry out loudly, but this time both of them were tender. Zim's dick pressed against Gaz's hymen.
"This is it, Gaz," Zim said in the soberest tone. Gaz smiled and nodded her consent. Zim pushed an inch passed, breaking her hymen. Instead of pain, Gaz squirted in unknown pleasure. Zim waited for Gaz to recuperate. Gaz's tongue hung out of her plump lips on the left side of her mouth. The girl vigorously nodded her head for more. Zim slowly thrust in and out of Gaz's tight natch.
"Ah, yes, soooo good," Gaz moaned. She enjoyed her first time being taken from a massive dick like the one Zim has. Zim's hands groped Gaz's mammoth soft breast. He squeezed her nipples between his middle and ring fingers. Gaz's back arched into Zim's chest in a gasp. Zim bent over and kissed Gaz. His hips gently plopped against her thick ass and thighs. He rolled her breasts in his hands, softly fucking her. "Ooooh, it feels good," She cried softly. Her voice sung like a soft violin. She felt so happy. From Zim admitting his feelings for her to losing her virginity to Zim on a heart-shaped bed as his sex slave. "Ooooh," Gaz's moan was cut off by Zim's dominating lips. His tongue drove deep into her mouth. Zim's hips continued sticking his dick into her flaming pussy.
After half a minute into the kiss, Zim stopped kissing her. His slow tender insertions became harder and deeper. The alien's dick drove into her cavern. "Oooohh fuck," Gaz gasped. Her head fell back with her eyes shut tight. Zim gently forced more of his dick into Gaz until the halfway mark. He stopped then kept fucking her with only half of his dick inside her. Gaz moaned, "Are you AH! Enjoying your slave's pussy Oooo, master?"
Zim grinned, "I'm enjoying it just as much as your mouth." Gaz's stomach fluttered with happiness. It was her goal and purpose now to let the master enjoy the use of her body. "Tell me how badly you want the rest of my dick," Zim grinned.
"Ahh!" I'm happy Ah! To be fucked silly Ohhhh shit by you, master," Gaz gasped between moans. "Even with just Ahh the head. Please! Fuck me with your entire cock! Ohh gods! I want it balls deep inside of me, Master." Zim stopped his hips. He slowly inserted the rest of his dick inside her. The wet cave clamping snuggly around him like a glove. "Ohhh!" Gaz felt every new inch with the joy of a child and the pleasure of a blissed-out bitch.
Suddenly, Zim's penis head hit the back of her womb. Gaz gasped. So this was what Zim meant by ridding her of her 'annoying cervix.' Zim grinned, "There, All twelve inches inside you." The alien patted her bulging stomach. He gave a small thrust inside her and smirked at Gaz's whining moan.
Gaz grinned like a happy lunatic. Her smiling opened mouth emitted low throaty laughs and her half-lidded eyes danced around their eye sockets. Zim watched as Gaz's head rolled back and her body went limp. Zim slowly moved his dick as it hit the very back of her womb. Gaz's lazy eyes looked down at the bulge tenting in her stomach. Twenty seconds later, Zim picked up his pace. He slowly increased his thrusts. Leaning over and kissing her, Zim's tongue spun around inside Gaz's moaning mouth. Gaz's eyes rolled up as she grunted with each thrust.
Zim suddenly growled, "I'm going to cum."
"Yes, please Master! Let's cum together." Fill my womb with your delicious cum!" Her wail caused Zim to give one last thrust as they came at the same time. Gaz's eyes rolled up and her body shook and tensed all over. The warmth of Zim's cum could fill a pint of milk. Zim's hips pressed snuggly against Gaz's thick ones, staying balls deep into her warm pussy. She soon recovered after cumming and felt Zim's dick still fully erect and hard inside her. The head of his cock pressed firmly against the very back of her cum filled womb. Gaz saw Zim's gentle smile but also a furrow of his brow and a possessive dominance to his demeanor. "How are you still hard after cumming twice?" She asked.
"Males of my species can stay hard as long as we want and cum any amount we choose. That's why our balls are bigger," Zim grinned, leaning forward towards her sweaty face, "And I don't plan going soft until after I fuck and cum inside your ass." He pulled out his dick, watching cum spew out of Gaz's freshly used virgin pussy like a faucet. "Another feature the collar has is it can stop you from getting pregnant by me, no matter how much I cum inside you. It can also make you so fertile that you would get pregnant the instant I cum inside your pussy." Then in a clear firm order, Zim said, "Now turn around and put your ass up and your face down to the pillows."
Gaz happily obeyed, "Yes master." Once in the position, Zim enjoyed the view of Gaz's magnificent ass and what he planned on doing with it next. He placed his cock right between Gaz's asscheeks and hot dogged between the sweet warm balls of flesh. Then he grabbed her hips and moved his hips slowly. "Mmmm," Gaz moaned in pleasure, "Oh, Master, I've always wanted to experience hot dogging a cock with my ass." Gaz gripped the sheets and kept her face looking forward at the pillows and the headboard.
"And I bet I'm not the only guy in school that's wanted to do this ass, including fucking it," Zim smirked. Gaz's body tingled as Zim's hot rod rubbed against her buttcheeks. She could feel the Master enjoying himself, adding to her overwhelming delight in her heart. A sudden slap sent a shiver down her spine.
"Well, no one could ever radiate such a powerful and dominant presence that demands complete obedience like you, Master," Gaz moaned.
Zim gave a sinister grin, "Damn right." Zim began hot dogged Gaz's lovely massive ass. The feel of her submission allured Zim like a bee to pollen. "You're my slave now," He hissed. His hands grabbed her asscheeks. He gripped the milky warm flesh. It molded so well in his hands, jiggly, round, soft, all the perfect feelings. With a lick of his lips, he squished her cheeks together on his dick. After another thirty seconds, Zim let go of her ass. Gripping his foot-long dick, he aimed the head at her asshole. He heard her gasp when he pressed against it. The hole winked at his dick, opening and closing tightly around the front part. Zim's hands, still on her thick hips, felt her tremble under his hands. Zim grinned widely, "Ready to have your third hole filled balls deep in cock."
Gaz looked back, smirking as she swayed her hips left and right. The little horny tease wanted to be fucked relentlessly. "Yes, Master," She said breathily. Zim slowly inserted his member inside of her. Inches gradually sunk into Gaz's constrictive hole. "Ohhhhh fuck," Gaz moaned gladly. Zim's member spread her wide, caused her pussy to drip more of his cum down her legs, and made her spit drool out her moaning pouty lips. Once balls deep in Gaz's ass, Zim's dick was in the same depth as he was in her pussy.
Zim moved his hand back to Gaz's hips and started fucking her slowly. "Oooooo," Gaz moaned as Zim went faster. The Irken grinned, enjoying every bounce and jiggle of Gaz's ass. Gaz's ass laughed and danced like vibrations of a guitar. It bounced nicely like a pornstars when being fucked from behind. In fact, thanks to the many invisible recording video camera balls, Gaz was practically a pornstar. Zim's lips curled up. He always fantasized fucking a pornstar and now he was doing it with her first performance of having her virginities taken.
Zim halted his hips. While Gaz's face was planted on the pillows and her ass high in the air, Zim grabbed her wrists and pulled her back. Her front raised up, causing her boobs to dangle down like massive water balloons. Her breasts bounced free. "Your ass is amazing," Zim grinned, "and it's just as tight as your mouth and pussy.
Gaz replied in shameless pleasure, "I'm happy that you're enjoying the use of my body, Master. Oh, fuck! Your cock feels good."
Suddenly, Zim's face twisted and strained. His hips pumped her ass faster as he pulled her wrist back further, raising her body torso higher. "I'm going to cum inside you, Gaz," Zim grunted.
"Me too Master," cried Gaz, "I'm going to cum too! Please unload everything in my virgin ass!" They both came at the same time. Gaz's eyes rolled up as the gurgling sound of Zim's thick cum entered her ass. Her head rolled back at the convulsing pulse of Zim's thick member. She felt the warmth spread from her ass and belly to her whole body. Delirious set emotions rattled her brain as she rolled her tongue out and let it dangle there. After unloading the same amount of cum in her ass as he had in her mouth and pussy, Zim released her wrist. Gaz's upper body collapsed to the bed with her face down and her ass up, unconscious. Zim pulled out and smirked at the sight of his cum spewing out of Gaz's freshly used virgin ass.
After the last of his cum spewed out, Zim let his hard dick go soft, drooping down to six inches, then he moved under the covers with Gaz on his left. He wrapped his left hand around Gaz, pulling her closer to cuddle. A minute later, Gaz's eyes returned to normal and saw she was in bed with Zim, cuddling like she fantasized after sex. Well, almost. Gaz placed her hand on the right side of Zim's chest, wrapping her left leg over his, and then She placed her face on his chest. Now they were cuddling like she fantasized. "You were incredible, Master," Gaz said.
"And so were you, Gaz," replied Zim. Then he kissed the top of Gaz's head, making her feel so happy as she drifted off to sleep. Zim saw her relaxed breathing and looked up at the ceiling. "Zim, you are The Irken," He thought to himself with a much bigger ego than his dick
