You come home from work and throw your bag onto the couch. "Princess, is there still dinner left over?"
"I thought we'd skip straight to dessert tonight~" Grace calls. You follow the intoxicating scent of fruit and whipped cream into the kitchen.
As soon as you cross the threshold, Grace whips a dollop of hand-whipped cream at you. It smears across your eyes and turns them a seductive, delicious pink.
"Princess!" You scoff. "What the h-" You feel it sinking into your face. You feel… looser. More gelatinous.
Your brain even easier for Princess to sculpt.
She opens the oven and pulls out a golden brown, baked to perfection copy of her hair. There's even a jelly streak over one eye. Princess places it on your head and tops it with a healthy dollop of whipped cream.
"You're a good little trifle twin." She teases. "Demanding, domineering, and teasing to a tee." Her words stick in your semisolid brain. Your tongue pokes out of your mouth. "But it only takes a nibble to send you spiraling back to submission."
She bites off a bit of your nose and promptly replaces it. Your eyes roll back in your head from bliss. "Yes, Princess~" You moan. You stain the front of your pants with whipped cream.
You refuse to strip, but you find it hard to talk back when she eats your tongue. "Good girls can't talk back~" The dommy part of your brain wants to cross your arms and stomp your foot.
The part of your brain melting with pleasure takes your clothes off and watches layers of jelly and cake replace your body.
"About time." You say when she attaches your big, cream-filled dick. Just an inch or two shy of her own, of course.
She wipes some of the pre-cream off the tip and spreads it on your tongue. You look cute when your brain goes all wild with pleasure and you have to clench your big, jiggly thighs~
Before long, you can barely remember your silly old flesh body, and you're over the moon with how much you love being Grace's trifle twin. Especially when she makes you wear the maid outfit and serve snacks to her friends. <3
