Well, in for a penny, in for a pound, right?

Just as you're about to cum, you quickly pull out of both girls, their pussies making a lewd sucking sound as they moan and writhe against each other. When your cocks are fully out of their wet heat, they turn and look at you, begging with their eyes, as they are still trying to actively suck the others tongue down their throats, to put your cocks back in and pound them until they can't feel their legs anymore.

"Not yet my dears"you smirk down at them" I have something else in mind for you two." The look of confusion on their faces quickly turns into a look of panic as you reposition yourself at their backdoors. "No, stop! We haven't had anything in our asses ye-AAHHHH!" Oh fuck, they are tight! The whimpers they made as you reposition their intestines to make room for your cocks slowly morphed into cute little moans and gasps as you ravage their insides. You notice that they their moans are getting quite high pitched, and a minute later you find out why, as their holes start to clench around your cocks and their pussy juices drench your thighs. A few more strokes and you bury yourself as far as you can into their asses, letting out a few moans as you fill them up spurt after spurt of your demonic seed.

They collapse bonelessly to the ground, panting and slowly coming down off their orgasmic high.
