In the woods at a abandoned haunted mansion, Kevin is searching for the man-made monster known as Frankie Stein. He looked every rooms in the mansion, but can't find her at all until he found the basement, Kevin walks towards the door, he peeked in the corner of door and see someone in the basement!

Standing just in the room was a girl, but not just any girl, a MONSTER girl. She had pale green skin with stitching along her arms, legs and face with a curvaceous and enticing hourglass figure. She had long streaking black and white hair that reached down to her shoulders, luscious red lips, a pair of differently colored eyes – the left being green and the right being blue –, and a set of silver bolts sticking out on the sides of her neck. She wore a blue top with white sleeves and collar that had a yellow 'F' on the upper left of the front, a set of silver belts around her waist, a black and blue checker skirt with yellow lightning bolts in certain spots, yellow circular earrings, and a pair of high black shoes with yellow laces.

It's seem that the basement is a laboratory and she is doing expertiment in the lab.

Kevin: Good, she is distracted right now!

While she is not looking, he quietly opened the door and entered the laboratory, he slowly walks towards the distracted monster girl with a collar in his hand. As he reached the monster girl she turned around seeing him behind her!

Frankie: WHAT THE ...? Who are you?

Before she had a chance to react, he put the control collar on her neck. She tries to take off the colar, but it was already too late the collar took a effect on the monster girl, her eyes starts glow and fade away afterward.

Frankie: Hello my master! What can I do for you?

Kevin: Tell me your name!

Frankie: My name is Frankie, my master!

Kevin: Okay! Suck me off now!

Frankie: Alright!

Frankie had undo the buckle and zipper of Kevin's pant. Frankie released his pants and pulled down his underwear, freeing the fully erect 10-inch human penis and big balls from their confinement.

Frankie: W-Whoa!

She awe at the bobbing shaft.

Frankie: So, this is master's penis? It's bigger than any of the ones in the guide.

Frankie stared with intrigue at the fleshy rod. Carefully, she grasped the member with her hand.

Frankie: Wow, it's so thick. My hand doesn't even go all the way around it.

She started rubbing Kevin's thick cock up and down with her hand. Ken bit his lip as Frankie pumped his pecker, sending a strong sensation through him.

Frankie: Does this feel good Master?

Ken: Y-Yessss…

He mumbled with a hot breath.

Frankie smiled with excitement, happy to know that she was making her master feel good with her "knowledge of human". She continued to pump his shaft over and over again. She then used her other hand to help with the pumping, making Kevin moan out at the second hand on his member jerking him off.

Frankie was looking directly at Ken's cock as she jacked him off. As she pumped his shaft with all her might, trickles of trickles of pre-cum were beginning to escape the slit of Ken's second head.

She paused with jacking off Ken, giving the normie boy a chance to breath. She looked over to the magazine and flipped through the pages. "It says that something is supposed to come out once you do this enough.

Kevin: F-Frank-kie! Is something wrong?

Frankie: No, I need to try a different technique!

Kevin: Okay, go ahead!

She released her hold on Kevin's shaft.

She removed the shirt from her chest, a pair of big G-cup pale-green breasts with dark green nipples bounced free. Ken's wide eyes were locked solely on Frankie's exposed globes, stunned by their size and beauty.

Frankie: Now that feels a bit better.

Frankie sighed as she shook her now free bosom. She looked back towards Ken who was stunned by the naked franken-girl.

Frainkie: Okay, let's try this.

Franked kneeled down before Ken, face to face with his twitching cock once more. She took hold of each of her ample mounds and pressed them around his huge member.

Kevin: Ngh!"

Kevin grunted at the sudden feeling of the two incredibly soft mounds pressed up and squeezing his shaft.

Franke: How does that feel Master?

She asked with honest curiosity.

Frankie: Does it feel good? I…I've never done this before, so I don't really know.

A dark green blush graced Frankie's cheeks. Seeing the blush cross Frankie's face made Kevin's heart melt. The part of him that knew they should stop had all but gone quiet.

Kevin: Y-Yes… It…It feels r-really g-good, F-Frankie.

Frankie beamed, happy to know her actions were making Kevin feel good. "

Frankie: Great! Then let's keep going.

Frankie continued to pump her master's cock with her breasts, making him moan and groan with arousing pleasure.

Kevin: F…F…Frank…kie…

He panted heavily as Frankie gave him his first ever tit-fuck with large breasts. His mind was clouded with lust and his body was unable to move. All he could think about and feel was Frankie's soft warm breasts squeezing and fondling his cock. This was another first for him, and it felt even greater than when Frankie was jerking him off.

For her part, Frankie was solely focused on making her master feel good. She had read in the magazine that her technique was a favorite amongst human males and judging from the expressions on Kevin's face she was certain that he was enjoying himself. She was also happy to find that her breasts were good for something. She sometimes wondered why her father gave her such a big chest, besides that to match her mother, but now she was happy to use them to help make her master feel good.

She kept pumping Kevin's shaft with her breasts, making the young man moan and grunt as all he could feel was a blissful sense of pleasure. However, as Frankie kept fondling and pumping his shaft, combined with her earlier actions, Kevin felt a familiar sensation begin to build. With each raise and lower of her mounds, Kevin felt the need to release rising more and more and knew he would not last much longer.

Kevin: F-Frankie!

He could feel the pressure in his loin building up to intolerable levels, ready to blow at any second.

Frankie increased the pace of her pumping, making her breasts bounce up and down rapidly around Kevin's pulsing penis. To her surprise she could feel it getting slightly bigger as she was sure it was almost about to blow. Kevin tried to resist release but found that Frankie's breast just felt too good. He could not hold back any longer; unable to resist any more. He needed to let it all out. He came.

Kevin: YAH!

Kevin exclaimed as his seed jettisoned out of his cock and right into Frankie's face.

Frankie: Gwuah?!

Frankie grunted in shock as Kevin's splooge sputtered into her face. A good portion hit her before she managed to use her breasts to direct Kevin's erupting rod upward. She watched as Kevin's cum ascended into the air before coming back down, staining her pale green bust. Frankie was astounded by the copious amounts the came out of Kevin's surprisingly still-hard rod.

Kevin panted as his release came to its end. His nerves were overwhelmed by the sensation, one far bigger than any time when he had jerked himself. Even more surprising, he was still hard, something that rarely happened after he reached his climax. His thoughts on himself however stopped when he saw Frankie wiping the cum off her face.

Frankie gathered all the cum off her face into her hands and licked them clean.

Frankie: Hmm…

Frankie hummed as she savored the taste of Kevin's jizz.

Frankie: Salty, but really good!

She gave her master a bright smile, leaving her master even more stunned. Frankie looked down and pouted at Kevin's shaft between her breasts.

Frankie rose up from her kneeling position, moving her bouncy bosom away from Kevin's rough rod. The franken-ghoul removed her shoes, socks, skirt, and black panties, exposing her lower half just as much as her naked top.

Kevin was unable to resist drooling at Frankie's large pale-green rear which matched her chest in size and shininess. Frankie turned around, giving Kevin a full view of her own womanhood, a pair of soft lips between her legs which were dripping with juices.

Frankie: Alright then, now let's see how this works. I-I've never done this before so please bear with me master.

She walked over to him.

Kevin: H-Huh?

He could mutter, still stupefied by her beauty.

Frankie walked right up to him and stared down at his twitching member. She bit her lips for a moment in hesitation before reminding herself she was a monster on a mission.

Frankie: Okay master, time for the 'main course'!

She got onto her knees, swung one leg over his crotch, and began to lower herself onto his cock. She slowly lowered herself down onto Kevin's shaft, shivering as the head first entered her followed by the rest of the girthy appendage.

Frankie sat down and took his entire length inside her.

Unlike a human girl, Frankie lacked any hymen so the only pain she felt was from the stretching of her snatch due to Kevin's shaft.

Frankie: I-It f-feels b-bigger than it l-looks,

Frankie stuttered as she got used to Kevin's size.

Kevin: F-Frankie…

Kevin muttered as he felt Frankie's pussy clamp down onto his cock. He could feel the franken-ghoul trembling above him.

Frankie is now adjusted to Kevin's member inside her. She locked eyes with him and leaned in close. Slowly, she moved herself off of Kevin's cock until only the tip remained before slamming herself back down to the hilt.

Kevin: NGH!"

Kevin grunted as Frankie rammed herself back down onto his cock.

The franken-ghoul proceeded to ride Kevin like a bucking bronco, going up and down his shaft with her own rhythm. As she did so, her exposed cum-coated rack bounded up and down in sync, making the ghoul look lewder than she already did.

Frankie: F-Feels so good!

Frankie moaned as she rode Kevin's cock. It was a strange sensation, but she knew that she would quickly grow to love it as much if not more than sucking Kevin off.

Frankie: This feels so good Master. You're so big and hard, you're making my insides stretch. Does it feel good for you Master?"

Kevin did not answer coherently. He was only moaning loudly, overwhelmed by the intense pleasure that seemed to course through his entire body and converge on his dick. Frankie's tight cunt drove his nerves wild, making him lose all sense of resistance and instead embrace the carnal desires that now consumed him.

Kevin: Frankie!

Kevin growled out as he let his desires consume him. With strength he didn't even know he had, Kevin reached over and grabbed a hold of Frankie's Fine-Stein ass and began to buck his hips, fucking Frankie even harder.

Frankie: AH!

Frankie exclaimed in surprise as Kevin took control of the situation.

Kevin rammed his cock into Frankie's tight snatch like a jackhammer gone wild. Gone was the normally level-headed human, replaced with only a beast ready to breed the female near him. Despite this, he did not let this overtake him to disregard Frankie's own pleasure. His hands caressed her entire body, teasing her form with gentle nudges and pats. However, his main focus was driving his shaft deep into the ghoul that was riding him.

Frankie's mind was swirling. Kevin's shaft was driving her mad and her entire body wild. She could feel herself ready to lose control and felt something bubble inside her she never had before. Something was building, something forming from the intense pleasure Kevin was giving her. She wasn't sure what it was, unable to remember anything from the magazine, but all she knew that it was coming, and that she would be unable to resist, nor did she want to.

Frankie: MASTER!

Frankie cried out as she felt her first ever true orgasm. She had experimented before thanks to the magazine, but never felt such a sensation in her entire life. Her juices sprayed out of snatch, coating Kevin's dick and crotch in it.

Feeling Frankie cum made Kevin snap out of his carnal mindset, allowing him to stop and pause to let Frankie ride out her orgasm. As his mind also cleared up, he couldn't help but marvel at the satisfied/blissful expression Frankie made as she came.

When her release came to its end, Frankie panted heavily. Her entire body slumped against Kevin's, her naked breasts against his clothed chest. She could still feel Kevin's rod fully hard inside her, making her mind swirl with lust.

She gave him a kiss on the cheek before whispering.

Frankie: I want to be fucked some more, master!

Kevin nodded and drove his cock back into her.

Frankie: AH! Master! Ah!

Frankie moaned as Kevin continued to piledrive himself into her. Each slam between his hips and her buttock let out a loud smack accompanied by the squelching sound on his cock pushing into her dripping wet cunt.

Kevin: F-Frankie!

Kevin howled, completely lost to the feeling of Frankie's tight insides. The electrically-animated girl's inside clenched tightly around the young human's prick. All he could think of was how good Frankie's insides felt around him.

Frankie: Ngah!

Frankie cried out as she bounded up and down on Kevin's lap. Her big breasts bounced brilliantly before Kevin's eyes, arousing him even more with each thrust. Frankie could feel the head of his cock push into her womb with each thrust, driving her nerves wild. "

Frankie: M-Master! I-I f-feel s-so g-good!"

Kevin: M-Me t-too! F-Frankie!

Kevin panted as he continued to plow the franken-ghoul's undead field. His eyes met with her differently colored ones before lunging forward and claiming her lips into hers. The two poured their very souls into that kiss as they fucked each other like animals. Kevin's chest pressed up against Frankie's boobs, squeezing them between their bodies.

The squelching sound of linkage reverberated through the room, accompanied by their respective moans. The two teens held tightly onto each other, locked in their lovemaking embrace and their minds lost to their respective lusts. They pulled away from their heated kiss!

Frankie: M-Master! Oh Master!"

She cried out, her mouth in a gaping grin. Never did she think she could feel such undeniable pleasure. She had never felt such a charge in her entire life, not even when she had been struck by lightning. Kevin's cock hit the hilt with each thrust, driving her mind wild and her bolts to spark.

Frankie: So good! This feels so good! I never want it to end!

She could feel something inside her building, reaching its peak and about to release.

Kevin: Frankie!

Kevin cried out, grinding himself into Frankie's tight cunt with each thrust. Like her, he was on the verge of reaching his climax. This however, momentarily snapped Jackson out of his lust-filled mentality and his sense of worry returned. "

Kevin: Frankie! I-I going to cum!

Frankie: Yes!

Frankie cried out as she continued to ride him.

Frankie: I want it inside!

Kevin was smiling when Frankie crashed her lips onto his, intensifying her actions and riding Kevin's rod wildly. Kevin tried to move, but Frankie had her arms tightly around his body. Despite his tries to move, Frankie's hardcore fucking was overwhelming his senses. With all his energy gone, Jackson could not fight anymore. Nor could he hold back on his release.

Frankie: OOOOOH! Master!

Frankie cried out as she felt Kevin's rod thicken before shooting his surprisingly massive load into her. The sensation overwhelmed her own control and she came to her own orgasm. Her vaginal walls tightened around Kevin's cock, making him shoot more of his hot spunk inside her. At the same time, her bolts spark wildly with electricity, creating a brighter flash than ever before.

Kevin: FRANKIE!

Jackson howled as he came. His load flowed into the franken-ghoul like a rushing river. This was release was far bigger than the last, overflowing Frankie's womb and making her stomach expand in size.

The release lasted about three minutes before both were spent. Frankie's stomach looked to be a few months pregnant with Kevin's cum and her own juices escaping out.

The two of them moaned out in satisfaction as they felt their bodies go limp. Kevin dropped onto his back on the bed and Frankie fell onto his chest. With all the cum inside her cunt and Kevin's member now limp, the appendage easily slid out and a small amount of his and Frankie's juices oozed out of her pussy while the rest remained inside.

Frankie: That…was…voltagous!

Frankie panted as she lay on Kevin's chest, the two panting heavily.

Kevin: I…I'll…s-say…

Kevin panted with equal tiredness.

Kevin: A-After we rested! We are going to my hideout, okay!

Frankie: Yes, master!
