She decides to fuck both of you at once.

Finally your mistress pulls out and you think for a second her desire has been fulfilled. This is not the case you soon see as with a wave of her hand and a brief touch to the boots you see her massive rod splits till there is a second identical cock hanging between her legs. “Now climb onto your sister Ilaya, I want your backs together so I can taste your cunts at the same time. As for you Ayali, you may lie there and enjoy I like looking at you like that. You would dare give me commands, for that you will see nothing but the floor as I fuck the both of you.”

“Yes mistress.” You both answer and know your new names to be Ilaya and Ayali, her lusty twin daughters.

You climb onto her back and throw your legs into the air. Your mistress however takes your legs and pushes them down onto your smashing your tits and has Ayali reach back and grab your heels holding you in place on top of her.

“Now you feel my power don’t you.” As she says this she enters both of your pussies with a savage thrust burying herself deep within your both impossibly deep. “Beg me to cum within you or I shall never stop.” She demands.

Waves of **** ecstasy wash over both of you as she fucks you. You want to do as she asks. The collars demand you do as she asks. But the pleasure is to intense, the heat of your twins body below you and the pounding of your mistress is to much to resist. Despite your orders the way they were worded you can’t do as she asks, for you both simply do not, can not let her stop. You hear yourself moaning in delight as the orgasms rock your body in waves. Perhaps she has given the two of you to much stamina, to much desire, who knows, but she continues fucking you both for quite some time, never letting up and she offers the same demand a second, then a third, and a fourth time all the while you and your sister **** resist the call and simply moan and squeal in delight as she fucks you relentlessly.
