Yes

"Oooh Fuuuck…" he moans throwing his head back. "Suck it. Suck my cock"

He arches his back and thrusts his hips upwards, showing his cock deeper in your mouth for your great delight. You can't believe how good it feels, how tasty his pre is. He puts his hand on your head, and bracing yourself, you push all the way down to his pubes, taking his whole length down your throat without the slightest problem.

Those two celestial beings really did a wonder with your body.

You reach out to your brother's mind again, and feel a deep satisfaction seeing his heterosexuality flickering. Apparently a nice incesteous blowjob was very efficient.

You keep bobbing up and down, hungrily sucking his meat, wrapping your lips and your tongue all around his tip and his shaft, until…

"Oh- s-stop… I'm… I'm gonna…fuuuuuck"

Not caring the least about his warning, your keep his cock in your mouth as it fires hot, long, tasty loads of cum in your mouth. Cum that you gulp down happily.

He falls back onto his bed, exhausted, but you're far from done with him. You still haven't cum, and your body yearns for, demands immediately, begs to have some sex. You use your new powers to make him horny and ready again.

Looking at his stiffening cock, you wonder. Your demonic cock is hard as wood, and you really wants a piece of your brother's ass. But on the other hand, your own ass is just begging to be fucked, you asshole throbs at the idea of getting fucked by your own brothers. What to chose, what to chose.
