Scott was passed out across his bed, totally oblivious to the fact his bedroom door was slowly opening.
Beth poked her head around the door, and surreptitiously surveyed the room. Her eyes eventually focused on her completely naked brother, who was flat on his back, width ways across his bed and snoring loudly.
"Scott? Are you Awake?" she whispered, pushing the door open all the way, and entering the room. Beth was completely naked too.
Beth skulked across floor and up to the side of the bed. She climbed on into a kneeling position next to him. Beth looked down at Scott's flaccid penis and a facetious disappointed pout formed on her face. She reached out with a finger and ran it along his soft fleshy cock. When she reached the end, she pulled her finger away, and Scott's penis instantly hardened and stood tall of its own accord.
"That's more like it gorgeous boy," Beth said with a grin, before lifting her leg over her big brother and straddling him. "Ready to fuck my pussy big bro?" Beth asked Scott, who still had no idea what was going on.
Beth reached down for his hard cock and introduced the tip to her inner lips, and after she had taken her hand away, she lowered herself down around Scott hardened shaft.
Beth moaned, as she started to grind away, rolling her hips onto Scott.
Scott started to stir very slightly.
Beth began to grind Scott deeper into her, and Scott started to moan softly, still under the veil of sleep, but his body was aware of what was happening to him.
Finally, his heavy eyelids peeled open.
"Beth?" He rasped, more sober than he was before, but still buzzing.
Scott looked down at his cock, rhythmically vanishing up inside the beautiful slender teen that straddled him. Then he looked back up into Beth's lustful eyes, with more clarity than before.
"I fuuuucking knew it. You've wanted my cock ever since I pressed it into your ass crack, through your sexy bikini."
"Mmm, I think about that day whenever I play with myself, sometimes I even rub my bed post into my ass pretending its you," Beth groaned, as she bounced more intently. "Tell me more dirty things you've done to me Scott?" Beth said with another groan.
"How about when you caught me jacking off into your panties, did you like that?"
"Oh fuck yes, I wanted to be those panties. Anything else?" Beth moaned.
"Yeah, I've jacked off into your shampoo bottle."
"Mmmmm, your so dirty Scott, but thanks for coming clean."
"Well when you have finished riding my fat cock you'll come clean too," Scott said with a smirk. "Hey speaking of dirty, where's your friend? She can make my face dirty with that hot little pussy."
"She fell asleep," Beth said with a moan.
"We could always wake her."
"No, I think she left."
"Fuck, she was so fucking hot."
"Yeah I know she is," Beth said with a wry knowing smile.
Beth had reached a steady pace, between a slight bounce and rolling her hips back and forwards.
"Oh fuck, your pussy feels so good sis."
"So does your big juicy cock, big boy" Beth replied as Scott put his hands on Beth's slender hips, forcing Beth down his cock as far as she would go, then he started thrusting into her in time with Beth's bouncing hips.
"Oh god Scott, you have no idea how much I've wanted you inside me."
"Fuck, really?"
"Yeah, I have a confession to make, sometimes I come in and suck on your cock when you're sleeping," Beth smiled sheepishly.
"I knew you were a dirty little bitch. But it just makes you even sexier."
"You think that's dirty... how do you feel about you and one of your friends double penetrating me?"
"What the fuck? Really? Well if that turns you on, I'm all over it baby girl."
"Yay," Beth said happily, as she continued bobbing up and down on top of Scott. "Hey, I have another dirty idea, wanna take this to Mom and Dad's room?"
"Mmm, fuck yeah baby girl."
Beth clambered off Scott and back on the bed beside him. Scott sat up and got to his feet with a drunken sway. He turned to face Beth, who was also getting to her feet, but on the bed. Beth reached out to Scott and put both arms around his neck. Scott put his hands on Beth's ass, and pulled her into himself, where Beth lifted her legs around his waist.
"We might as well fuck on the way there," Beth said with a sultry look.
"I love this new you sis, you're fucking filthy" Scott said with a smile, as he reached under and slipped his cock back up into Beth, who moaned loudly as he slid inside. Then he grabbed her toned ass with both hands and carried her to the bedroom door.
His first few steps were slow and steady, so as not to become unstable with the extra weight. As Scott carried Beth out into the cool hall, his confidence grew and his pace picked up slightly.
Out in the hall, Scott carried his little sister along the hallway, then down the stairs. Scott's left hand rested on Beth's ass, feeling her bounce on his cock, as they descended each step. The other hand provided much-needed stability, as it glided down the rail beside them.
At the bottom they turned ninety degrees and walked down the hall away from the front door, reaching the living room door on their left.
As they passed, they heard the faint snores of someone asleep in there.
"I guess your friend didn't leave, shall we go wake her up?"
"I was kinda hoping it was just gonna be us."
Scott smiled, as he gazed lustfully into Beth's eyes.
"Sure thing sis."
At the end of the hall they turned right into a short hall with their parents bedroom at the end.
Scott pushed the door open using Beth's back and they traveled to the bed, where Scott climbed on to it, still holding on to Beth. Scott walked them both across the bed on his knees, and he finally completed their journey by laying Beth down beneath him, his cock still buried inside her.
Scott leaned in and kissed Beth's neck, as his free hands reached up to her breasts and her squeezed them firmly.
"So, who is this Maddie girl?" Beth asked.
"Mmmm, just a girl at work," Scott said between applying kisses to Beth's neck.
"You wanna fuck her don't you?"
"Well yeah, she's smoking hot," Scott said, pulling back to look at Beth, before going back to work kissing her neck.
"I can help you with that," Beth said.
As the words left Beth's lips, Scott realized that her breasts were growing an extra cup size. He pulled up away from Beth, taking a look at what was happening beneath him.
"Maddie?"
Maddie was almost identical to Maeve in facial features, albeit with a longer, more mature face and a few feint wrinkles. Her buxom body was much taller than Maeve's, with a long elegant quality to it.
"Yeah. So you want to fuck me, do ya?"
"Uh... but, how are you...what the fuck happened to Beth?"
"I'll give you a full explanation after, for now lets just enjoy ourselves." Maddie said pulling her feet up against Scott's ass, which pushed his cock in deeper. "Ohhh yeah that's it Scott, fuck my pussy."
Scott humored Maddie's request, how could he resist her. But despite the lust that was coursing through him, he was still reeling from what had just occurred.
"Oh yeah that's it, honey," Maddie moaned, as Scott cautiously started to make small thrusts. "It's all gonna be fine baby, we are going to be so good together," Maddie said reassuringly as she caressed Scott's head, which dissolved the confusion in Scott's brain, and he instantly started putting more force in his thrusts, slowly picking up the pace.
"Oh Maddie, you're so fucking hot," Scott said staring down at her.
As Scott looked down, Maddie morphed again right in front of his eyes, her breasts shrinking, her entire pussy tightening around his cock, as her body frame shrank, her face growing younger and rounder.
"Maeve? Wait... you're Maddie... aren't you. What the fuck is going on? This is freaking me out now, but you feel so fucking good" Scott said with equal measures of panic and lust
"Its Magic, Scott" she replied, her hips bouncing on the bed from Scott's thrusts. "The thing is Scott, I have the power to fulfill all your wildest fantasies, you just have to say."
