Send Rachel to her room to rest

Prompt: Send Rachel to her room to rest while her transformation settles, then check on Kyle

Turn 10:

You pull back from Rachel's transformed face, watching the last traces of your essence glisten on her reddened lips. "Go to your room," you tell her, your voice carrying command threaded with affection. "Let the changes settle. Sleep if you can, though I doubt you will."

Rachel rises unsteadily, her legs trembling from pleasure and transformation both. She touches the small horns protruding from her hairline with wondering fingers. "What about Kyle?"

"Leave him to me." You wrap glamour around yourself again, this time choosing a different form—not invisibility, but Rachel's own shape. Her body, her face, perfect mimicry. "I'll make sure he's ready when the time comes."

Rachel's smile is dark with understanding. She gathers her discarded clothes and slips from the bathroom, moving with newfound grace toward her bedroom. You wait until her door closes before turning your attention to Kyle's room.

The hallway reeks of frustrated arousal. You can taste it in the air, the pheromones you released earlier mixing with Kyle's own **** need. His door is closed but not locked—an invitation, perhaps ****.

You don't knock. You simply open the door and step inside wearing Rachel's stolen form.

Kyle sits on his bed, still shirtless in those flannel pajama pants, his laptop open but clearly forgotten. He jerks around at the sound of the door, eyes going wide. "Rachel, I—"

"Shh." You close the door behind you with deliberate softness. The lock clicks. "I know you've been thinking about me. About what almost happened in the hallway."

Kyle's throat works as he swallows. His erection is obvious, straining against flannel, and he makes no effort to hide it anymore. "This is insane. We're twins. We're—"

"We're alone." You move closer, allowing Rachel's transformed beauty to work on him. The weak pheromones her changing body now produces mix with your own, creating a cocktail of desire that fills the small bedroom. "Mom and Dad are asleep. Nobody has to know what happens between us."

"Rachel, please..." But he doesn't say stop. He doesn't say no. His hand reaches out almost involuntarily, fingers trembling as they hover near your hip.

You catch his wrist, guiding that hand to rest against the curve of your waist. Through the glamour, you feel his touch, his heat, his **** wanting. "Tell me what you've been thinking," you murmur, settling onto the bed beside him. "Tell me the truth. What do you want?"

Kyle's resistance crumbles visibly. "I want... God, I can't believe I'm saying this. I want you. I've wanted you since you opened that bathroom door. Maybe before. Maybe for longer than I want to admit."

"Good." You lean in close, your lips nearly brushing his ear. "That's very good, Kyle. Honesty is important between us now."

Your hand trails down his chest, feeling his muscles twitch beneath your touch. His breathing has gone ragged, ****. One word from you and he would break completely.
