The family that plays together

You and your sister were merciless with the minotaur. There was no rhythm or grace to your vicious pounding. She clearly wasn't used to taking such a massive cock like yours up her ass, so everytime you **** your way through her anus it offered heavy resistance. Since your had your prey on her back, you could easily see your cock bulge and deform her belly with every thrust before being **** back out by how tight she was.

Meanwhile something very similar was happening to her throat around your sister's cock. You watched with excitement as she gagged and choked on it and little trickles of saliva and precum dripped from her lips. You couldn't see her face, but you imagined your sisters huge balls slapping into it every second and wondered if the minotaur would have two black eyes afterward.

It had been so long since you had seen your big sister that you had almost forgotten how unbelievably hot she was, especially with her cock holstered in another monster's mouth. She glared at her cock reforming the minotaur's throat with a hungry grin and licked her lips several times. Her hair was stark white, but not from age, more like a thundercloud, and her eyes were a smoky grey that gave her an air of mystery that always made you hard just looking at her.

When you had asked if she would demand to put a baby inside you, it was actually a not-too subtle suggestion. You had been dropping the same hint to her over and over again for years, but to your disappointment, she had yet to take you up on the offer.

After you both came inside your prey twice, you switched places, you taking the minotaur's throat, and your sister moving between her legs to destroy her pussy. While you choked the minotaur with your ribbed dragon cock, you watched your sister and fantasized about her ravishing you like that and almost came again at the idea. It wasn't that you didn't know what it was like to have her inside you, but it had never gone as far as her cumming inside your pussy, she always pulled out and smothered you with her cream instead.

Your sister's heavy thrusts were starting to lose their strength now and she was getting wobbly in the knees. Also her head was hanging back and her face contorted with pleasure. Finally, the two of you came in unison, your own pleasure coming from the fantasy that she was coming inside you instead.

You both screamed and the clouds all melted away at once bathing the field in bright sunlight which glistened off your skin. While your prey scampered away in defeat you wrapped your wings around your sister and the two of you collapsed in the long, wet grass to make out.
