A sparkly purple dildo

Meg runs over to the side of the room, her body moving like sweet jelly in that tight black dress. She bends over, clearly, happy presenting her cute ass to you, and reaches into a cabinet.

Then she turns with a smile, showing you a huge, massive, gigantic, sparkly, purple dildo.

The size just shocks you. You feel your clit itch. You feel your jaw drop. It's got to be 20, maybe 24 inches long. A head at both ends. And thick too. "What is that?" You ask. Although it's clear what it is. You can't think of any better question.

"My cock" Meg answers, echoing her answer from earlier, about the dumb rooster painting. She beams a big, horny smile.

And you can't resist this any more. You stomp across the room over to her and in her against the wall, thrusting your tongue into your sister's mouth, as deep as possible. She's taken aback at first, but quickly returns the favor.

And then you lose your footing. You're just too filled with lust. Your body shakes. You both fall to the floor.

Of course you don't care. You paw at Meg's body. You paw at her neck, her shoulder, her tits. You have to get her out of that dress. Quickly you find a zipper down her back and peel it down. The dress falls off her almost immediately. And there's her body, for your pleasure. Her pale tits, her pierced nipples, her pierced belly button, her bald, pierced twat. The two of you just write into one another on the floor for a bit. Two naked bodies. Two sweaty sisters. Flesh pressing against flesh. Breasts heaving up against breasts. Saliva dripping from both of your mouths, like you're animals in the midst of a kill. It's the most depraved moment of your life. And all you care about is making it last as long as possible.

Meg moans and groans. So this is what your sister looks like in the throes of passion, you think. You didn't realize it until now, but subconsciously you've wondered about it all your adult life. She looks amazing, like a ball of pure, naked, lust.

"Meg" you whisper between panting breaths. ".... we can never go back." You lick her pierced nipples, pulling on her nipple rings.

"I don't want to." Meg answers. Her fingers pinch and rub your swollen clit.

"Your body belongs to me now" you say, grabbing the huge purple monstrosity from your sister's hand. Being in charge has been working so far, so why let up now?

Meg may be the wild child, but you're the older sister. And now that you've got her favorite toy, you're going to give her the best fucking of her life.

Her big brown eyes gaze at you. You've never seen her give that look before. Every moment is a reminder that what you're doing is unconscionably taboo.

"Make me scream" She says.
