At that moment, Ty reverted from his "ghost" state back to reality. Fading into view, Dustin stared at the sudden Ty appearing behind him in bewilderment.
"You make a very nice girl, Dustin." Ty grinned, pressing his erect manhood into the crack of her ass.
This made Dustin blush deep red and she shook in terror. "T-Ty... what are you... what's happened to you?"
"Me?" Ty smiled, watching Dustin's pleasured reaction as Ty reached around her body and cupped his hands greedily around her large soft breasts. "What's happened to you?"
"T-Ty!" Dustin blushed redder, squeezing her legs together, still wet from cumming. "I... I..." The throbbing of Ty's cock against her shapely ass checks was enough to make her wetter. Dustin turned her head, licked her lips, and thrusted her ass against Ty's shaft, grinding it.
"Oh, my, my." Ty smiled wider. "To think this morning you were so mean to me."
"I'm sorry..." Dustin said in a sultry voice. "That was when I was a big stupid boy. Now I'm a small sexy little girl."
"Yes, you are." Ty grinned, squeezing Dustin's breasts in his hands and willing them to grow bigger. He chuckled as Dustin's eyes widened at the sight of her tits inflating into Ty's hands, spilling over his palms and around his fingers.
"Oh God!" Dustin quivered. "It was you!"
"Yes..." Ty said, gently leaning in and biting his former step brother's neck. "Do you like what I've done?"
Dustin was now shaking with both terror and erotic bliss. "We shouldn't." She whispered. "You should change me back."
"No, I like you this way." Ty grinned, pulling Dustin around and looking deep into her shining blue eyes. She turned away abashedly.
"Me too." She admitted, blushing deep red.
"Now, now." Ty gently cupped her chin and turned her face to his, slowly sinking in for a kiss. "Nobody is here to interrupt us, Dus...ty. Dusty."
"Yeah...?" Dusty said breathily, chest heaving as Ty wrapped his arms around her silken back and squeezed her breasts against him.
They began to make out, and as horny as both of them were, Ty easily picked the light and slim blonde off the ground and wrapped her legs around his waist. His cock ground against her vulva as they passionately made out. Before long Ty's shaft was soaked in pussy juice, and he pulled them out of the bathroom together and slammed Dusty against the hall wall, making her gasp in pleasure.
"Come on, little brother, fuck me. Make me a woman." Dusty said in gasps, reaching down and placing Ty's shaft against her opening. "Break my cherry."
"You better fucking hang on." Ty said with a growl, and plunged his cock in, snapping a hymen for the second time in a day.
Dusty screamed her delight and grabbed her hair and her face, blushing a burning bright red on her soft cheeks, as Ty hammered her against the wall, smashing her ass into the drywall with loud wet slurps. Eventually, Dusty went limp and Ty fell to the ground, pushing himself on top of her and frantically fucking his new step sister. She screamed in both pleasure and pain, her pussy in both, yet Ty kept slamming his entire shaft home. He watched with sweat pouring down his face as little Dusty started to gyrate and cry out, throwing her head back and arching her back as she frantically gripped the carpet.
"That's it!" Ty bellowed. "Cum, you little fucking bitch!"
Startled, but not surprised, Dusty relented and groaned as she orgasmed from her step brother's cock, feeling his own juices flood her at once and begin pouring out her pussy. Ty withdrew, stood above her, and walked into the bathroom as she lay gasping, throwing down a clean white towel on top of her and grinning with conquering domination.
"Here, clean yourself up, you fucking slut." Ty commanded and began walking downstairs.
"Go fuck yourself, asshole!" Dusty screamed back and grumbled as she began to wipe down her quivering pussy.
