Luke sat there, gazing at the screen. His 6-inch dick pulled out of his pajama pants. This had become a habit for him. He had watched porn over 400 times. Tonight, Luke sat in his room alone, watching two girls have sex. He was nearing his time. He put a pillow over his mouth and let out a long low groan. He shot seven streams of the sticky-hot goo into the napkin he held over his unit. Luke was in heaven, but his life was about to change. Emma had been watching in silence from the crack in his door. As Luke came, Emma pulled up her nightshirt and started rubbing herself. She pinched and squeezed as Luke recovered from his powerful orgasm. She squealed, and Luke stopped instantly. Emma put her juicy hand over her mouth. Luke slowly put his pants back on and crept towards the door. Emma was paying no attention to Luke as she licked the juices off her fingers. Luke opened the door slowly to see Emma with one hand in her mouth and the other in her pussy.

"Emma! What are you doing?" Luke whispered in a sharp tone.

"I'd ask you the same question!" Emma said.

"Wait, were you watching me jerk off?"

"No, I would never! Well, maybe I was OK!" Emma was obviously confused as she couldn't find a way out.

"Did…Did you like it" Luke asked.

"Umm…. Yeah I guess"

Luke stared at her gorgeous body. Captivated by her beauty.

"Do you, umm… wanna…"

"YES!" Luke blurted out maybe too loud.

Luke led Emma to his bed. They started making out, Luke's hand exploring Emma's body. Their tongues clashed against each other. Emma took of Luke's shirt, revealing his six-pack. She kissed his nipples and rubbed his abs. Luke began to take his pants off. Emma stared as Luke revealed his rock-hard 6-incher. She grabbed it and shook it around. Luke forced her head towards it. She opened her mouth and shoved it in. Back and forth she rocked. She did this for a couple of minutes. Luke got her up and stripped her down, leaving the heiress in her bra and panties. Her small breasts tantalized Luke. He grabbed them and fondled them in his hands. He hugged Emma and rubbed his dick against her midsection. Emma's bra came unclasped and she kissed Luke again. Luke sucked and liked at Emma's nipples. He had dreamed of this for years. He layed Emma down on the bed and straddled her. He began to shove right into her pussy. Emma let out another squeal, louder than the first. Luke pumped into her harder. Suddenly, the door to Luke's room opened. Jessie stood there in disbelief.

"LUKE, EMMA! What is going on in here?!" She asked in a shrill whispering voice.

"Umm… Nothing." Luke said as casually as possible, covering up his dick. Emma rushed to throw her nightshirt back on.

"Emma, don't bother, because I'm going to join you."

Luke nearly fainted. He was about to have sex with his amazingly hot sister and his nanny. Luke stripped Jessie. Her huge tits exploded out of her Texas sweatshirt. Luke grabbed them with his mouth while his hands groped Jessie's ass through her yoga pants. Jessie pushed Luke off with amazing ease.

"Luke, let me see your dick" Jessie said quietly.

Luke pulled his dick out of his boxers, as hard as it could be.

"Hmm… let's do something about that." Jessie said. Luke's dick suddenly began to grow bigger and bigger.

"Woah, Jessie, what's happening to me?!" Luke cried. His dick grew and grew till it reached about 11 inches.

"Jessie! How did you do that?" Emma whispered sharply.

"Well, I have the power to change people's bodies, how do you think I got to look so good? Why do you think your mom hired me?"

"So, you can change anything about anyone?" Emma asked.

"Yep, anything"

"Can you make my tits bigger?" Emma asked. Jessie pointed an eyebrow at Emma. She felt her chest lurch forward. Her breasts swelled and swelled. She went from in between an a and b-cup to a d-cup in 10 seconds.

"Oh, my god, yea!" Emma groped herself. Luke's mouth watered. He ran over to Emma and started groping her huge tits. Jessie came up behind him and sandwiched Luke between their tits. He grabbed their asses and drew them in close. Jessie and Emma made out above him.

"Jessie, I wanna look like you!" Luke blurted out. Luke's body began to stretch out. His face morphed. His butt reached out and gained curves. His stomach smoothened and his hips widened. His chest swelled up and his breasts expanded. Suddenly, there were two Jessies in the room. Luke was having so much fun playing with his tits, he didn't even notice his dick shrinking back into his body. He ran up to other Jessie and grabbed onto her. Jessie stepped back.

"You know Luke, I've always thought you were a cute kid, I wonder what it'd be like to be you." Jessie started to shrink. Her hips narrowed and her hair came back. Her butt became smaller and her abs grew. An eleven inch dick emerged from her groin. She was Luke, with one major difference.

"Jessie, you still have tits!" Emma said.

"I know, I couldn't live without them" Jessie admitted.

"Well you know what, I want a nice big dick" Emma said. She lurched back onto the bed. She groaned in pleasure as a footlong dick broke from her groin. She ran up to Luke and started shoving it in between his big tits. Luke getting used to Jessie's body walked over to Jessie and started sucking her dick. He had always wanted to but didn't want to come off gay. He throated his own dick on his own body. Emma was still tittie-fucking Jessie. They got up to reposition. Emma put her dick into Luke. Jessie inserted Luke's dick into Emma. They started chain fucking. Luke was in front taking Emma's 12-incher in his tight pussy. Emma was in the middle taking Luke's 11 inch dick and Jessie sat on the end shoving into Emma while grabbing her sexy ass. Suddenly the alarm clock rang. It was 7 AM.

"So, same time tomorrow?" Jessie asked.

"Yep."
