It was Saturday with Nia spending the day at the mall. It's been a week since she gain Zita as a second sex partner, which she and Bonnie have been teaching her the ropes of sex. But it did turn out that Zita played a lot of porn games and had ideas of her own. Like her and Bonnie used their breasts to sandwich Nia's cock and gave her a double boob job. Of course Zita's giant H cup breasts did out class Bonnie's F cups but Bonnie had an idea to use her big juicy butt. She sat on Nia using her big fat butt to sandwich Nia's huge meat log between her ass cheeks, while Zita continued to rub her huge breasts on the meat log that's between her and Bonnie.

But both Bonnie and Zita are busy to go and get fuck. Bonnie is doing something with her family, while Zita said that she wants to play a game and all the sex has been eating up her time to play it. Leaving Nia to spend the day alone without anyone to fuck, which she had gotten use to, thanks to either Bonnie or Zita or both having sex with her each day. Leaving Nia to window shop as she wanders around the mall.

She had played around on her computer using message boards. There's an app called 'Sex Hunt' Nia has been chatting with a Ms S. who she has sent pictures of her breasts and penis. All of which is discreetly as the site has rules that if broken the user will be banned. There is also a Dr. AP who is a new member who just divorce her husband and is now living with her daughter.

Nia's moms were working leaving her alone and so she decided to go to the mall. Which had her stopping at the high end store Club Banana, which carries many designer labels. Of course seeing how the same company that owns Smarty Mart both stores often carry the same items. The only thing different is being the small logo patch on the clothes, the price, and the name of the color.

Which is just a waste of money as Nia would only pay for pricey clothes only if they're well made and last for a long time. Not to mention thanks to her having a cock she has to wear baggy or loose clothes. Her choice of clothes are pants long skirts, dresses that she can hide her cock. That even when it's soft is still 6 inches making a bulge no matter what.

Nia wandered into the store just to see what's there. Which all the clothes are pricey and designer, which Nia has no idea why women spend hundreds on clothes that are the same thing that's in Smarty Mart. As some research showed that both stores are not only owned by the same company but also get the clothes from the same factory. (1)

That's when she spotted Kim Possible talking with the worker at the desk another girl who went to the same school, Monique. From what Nia knows, Monique is a black girl who keeps her dark hair long, and has a killer bod. She has the largest breasts in the school at I cups but she is also one of the tallest and biggest girls standing over 6 feet tall, than there's her butt that is the biggest that doesn't belong to one of the fat girls.

Kim wasn't bad either, even if she is the smallest girl on the cheer team. With small C cups and a well toned butt, Kim wasn't as eye catching as her much bustier fellow cheerleaders but makes it up for her firm and toned body. Which she got from years of saving the day as a heroine known world wide. Of course she hasn't been going on missions as she's taking a break after she and Ron broke up.

Which from what she heard, happen once Ron found out he's still rich thanks to the royalty checks still being sent to him. And according to Bonnie and Zita, he let the money go to his head again and spent way too much ending with him broke again. But this time he's doing time because of unpaid bills and not paying taxes on the money. And Kim left him because of him being a rich jerk and it wasn't the first time it had happen.

"My parents split up and me and mom haven't been closer. We really bonded since dad left," Monique said as she and her mom have been spending more time with each other. Which she doesn't want to tell Kim about, not knowing what she'll think about her having sex with her mom.

"It just taking some time to get use to, without dad or my brothers around," Kim said.

"You'll get use to it and you will have plenty of time to be with yourself without being called for a mission," Monique said.

"I really do need some me time," Kim said having been burnt out from being a heroine and her school life. She needed time off from that kind of life. "See you later."

"Yeah girl take some time for yourself," Monique said and watch her friend leave the store.

"So she doesn't go on missions anymore?" Nia asked making herself known.

"No she doesn't. Aren't you the new girl?" Monique asked seeing it's Nia.

"Yeah and I'm really surprise that no one really cares that Kim is a heroine who saves the world in this town," Nia said.

"Yeah, I'm surprise myself. Kim saves so many lives and the world with her helping to stop those aliens. I'm still shock that she's not the hero of this place," Monique said.

"I wonder if she doesn't mind not having people show her any respect for what she does for everyone," Nia said.

"Planning on her joining on in with the fun you and Bonnie have been doing?" Monique asked.

"You know?" Nia asked surprised.

"I was walking near the showers when I heard you and Bonnie having some fun," Monique said. "I never knew she was into girls."

"Oh," Nia said as Monique just thinks she's a lesbian.

"But you are pretty and from what, I...," Monique said as she press herself up against Nia ready to make her own moves on the new girl when she felt something poking her. Looking down she sees something that she only saw boys sporting. "You're a guy?"

"I'm a futa," Nia said.

At Monique's house -

Once Monique clocked out she took Nia home, with both of them taking their cars and Nia following her. Who had explained everything to her with her being a futa, Bonnie discovering her secret and them being lovers. Then got into how Zita had walked in on both of them while they were fucking and joined on in as well. Hearing about how much sex Nia has been having, Monique wanted to get into that. But not wanting to be caught at her work, she had to wait for her shift to be over before taking Nia home with her.

Monique and Nia strip off their clothes as they both stared at each other. Nia staring at Monique's bust and booty, and said girl staring at Nia's massive cock. Monique has been playing with her mom's collection of sex toys but she never thought she would see a real one that big.

"Well lets start," Monique said as she bends over on her bed wiggling her butt at Nia. "Ready to have a hell of a ride?"

"How about I take you to Heaven instead, baby?" Nia said getting behind Monique.

Monique rolled her eyes at that cheesy line, but her eyes stayed rolled up as she reacted to the thick cock that had just been stuffed into her. "Uuhhhnn! Aaahhhnn! No wonder you got both Zita and Bonnie wrap around your fingers. It's so big and feels so good."

SMACK!

"Damn! You've got a nice big fat ass, Monique!" Nia 'complimented' her as she slapped Monique firm and big butt cheeks a few more times.

"You know it!" Monique said taking Nia's massive cock like a champ thanks to her playing with bigger sex toys.

"And... Uuummmm! A nice tight cunt too!" Nia said as she began stroking in and out of her newest lover at a faster pace while her hands continued to torment her rear.

"That's right do me hard," Monique said as her first orgasm hit her.

At this point all rational thought fled Monique's mind as Nia's cock began penetrating her to the deepest extent possible, making her cum again and again. She could feel her hunched over her curled up body, driving her hips into her, while her hands reached around her body to cup and squeeze her bouncing breasts.

Nibbling on the edge of her ear Monique heard her murmur quietly in her ear. "You really do like this, don't you Monique? You like it when I fuck you hard again and again."

"Oh yeah," Monique said. Nia licked Monique ear lightly as her body spasmed from the force of her orgasms.

"How about we show everyone what kind of girl you really are?" Nia suddenly asked in a louder voice.

Monique's brown eyes widened at this. 'What is she...?'

She didn't have long to wait in order to find out.

"UUUUAAAAUUHHHNNN!" Monique yelled out loud in a combination of surprise and sexual joy as her lover suddenly picked her up in her muscular arms and walked her off the bed and over towards her bedroom window with her cock still driving into her dripping pussy with each step. Arriving in front of the window Nia quickly snagged open the curtains and pressed the buck-naked girl up against the glass as she continued to spear her dick into her repeatedly from below.

Monique's head shook in rejection of what was happening to her, but it changed nothing. She was now completely exposed to any passerby who might glance up over the garden wall and see her getting her brains screwed out by her new lover. And she never felt so turned on and alive. But then she remembers that her bedroom window face the backyard, and her house is one story and her backyard is on a hill overlooking the other house.

Between mind-shattering orgasms Monique tried to regain control of her body and actions, but it was impossible. Nia's skilled hands, fingers, and mouth seemed to be everywhere, perfectly anticipating just where to touch her to make her cum again and again. And that wasn't far from the truth, through her study of some sex aide books her knowledge of sex has expanded exponentially. Combining that with her... training with both Bonnie and Zita and Nia now knew exactly where and how to manipulate the human body to produce the effect she wanted. And right now that effect was sexual excitement.

Monique was screaming out in pleasure and her face was a display of complete ecstasy. In the midst of drilling up into her, Nia had suddenly maneuvered her right hand down to her rear and suddenly inserted one of her fingers up into Monique's ass. And that rude, disgusting, unbearable, foul, action had just triggered the most tremendous orgasm in the teenage girl's young life, making her howl at the top of her lungs until she finally passed out.

When she came to, the panting Monique found herself back on the tangled sheets of her bed. Picking her woozy head up she realized that she hasn't been out for that long. Looking to the side she saw Nia still there and her massive cock still rock hard.

Seeing her eyes on her Nia smiled smugly. "Well, I think its time to show you why Bonnie didn't mind having Zita join in on the fun. It takes alot for me to have enough and bring down my cock."

"Oh boy," Monique said scared and lust filled at the same time seeing that she's in one hell of a ride.!
