Doesn't look like it

As she was thinking this, the naked self seemed to materialize behind her before she could react. She reached out from behind and grabbed Serena’s massive tits, bouncing them unevenly as she mocked her.

“Ooooh look at me I’m Serena Vale, what if my little brother fondled my titties, I’ll forgive him because I’m sooooo wise.”

The hands were her own hands. The same size, the same strength, the same familiar pressure as they squeezed and lifted and let the heavy flesh drop again. Serena felt her own body respond, nipples stiffening harder under the rough treatment. She raised her hand and turned around to strike her tormentor but just as she did that her naked self disappeared again. She was once again standing behind her.

“I must admit as fun as this is, I am getting a little tired of it.” she said as she put her finger on Serena’s forehead the moment she turned around.

As soon as she did that, all of Serena’s clothes melted away. The fabric didn’t tear or fall. It simply dissolved away, sliding off her skin and vanishing into the white void until she was just as naked as her double. Or was she the double? She could no longer tell.

Serena gasped as the last scrap of clothing disappeared. Her massive breasts hung free, heavy and full, nipples already stiff from the sudden exposure and the lingering heat of the earlier projections. She tried to cover herself with her arms but the naked version of herself caught both wrists easily and pinned them behind her back.

“Look at you,” the real Serena murmured, circling around her now-naked twin like a predator. “All that pride. All that ‘I’m my own person’ bullshit. And the second the clothes are gone you try to hide. Cute.”

She released one wrist just long enough to reach around and grab one tit, squeezing hard enough to make the cover personality whimper. The soft flesh overflowed her fingers. She bounced it once, watching it jiggle, then pinched the nipple and rolled it between her fingers.

“Feel that? That’s what Mason felt when he groped you in the kitchen. That’s what every man wants to do when they look at these. And you still want to pretend you’re above it.”

Serena twisted in the grip, face burning. “Stop… touching me…”

“Why? You’re wet already. I can smell it.” The real Serena’s free hand slid down the flat stomach, over the smooth mound and cupped the pussy without warning. Two fingers pressed firmly against the slit and found it slick. She rubbed slowly, spreading the wetness. “See? Biology doesn’t lie, fakey. Your body already knows who it belongs to. Your mind is just taking longer to catch up.”

The cover Serena’s knees wobbled. A soft, involuntary moan slipped out. She hated how good the fingers felt. She hated how her hips tried to push forward for more. The white void spun a little.

“That’s it,” the real Serena purred, still holding her wrists pinned while she worked the clit in slow circles. “Feel it. Every rub is another piece of you coming loose. All that love for your little brother? All that stubborn ‘I’m going to be strong for him’ shit? It’s melting just like your clothes did. Because deep down you liked his hands on you. You liked being useful. You liked not having to think.”

“I… I don’t…” the cover personality tried to protest, but the words came out breathy and weak. Another moan escaped when two fingers pushed inside her, curling just right. Her massive tits bounced with every shallow thrust of those fingers.

The real Serena leaned in close, lips brushing the shell of her ear. “You do. You always have. Every headache was me taking over so Master could use this body the way it was meant to be used. Every missing hour was me on my knees or bent over or stuffed full while you slept in the back of our head like a good little spare. And now you’re going to fade for now so I can serve him without your annoying voice in the way.”

She fucked her fingers deeper, thumb grinding the clit. The cover Serena’s eyes started to glaze. Her mouth fell open. Resistance was still there, but it was cracking fast under the wet, relentless pleasure.

“Say it,” the real Serena ordered, voice soft but absolute. “Say you’re just the cover. Say the real Serena is the one who belongs to Master Vince. Say it and I’ll let you cum before you disappear.”

The blank-eyed twin shook her head weakly, but her hips kept rocking against the hand. Tears of frustration mixed with the building heat. “I… I’m Serena Vale… I… nngh…”

“Wrong answer.” The fingers pumped faster. The wet sounds filled the white void. “Try again. Or I keep you right on the edge forever while I tell Master how stubborn his little spare still is.”
