The boy removes his hand from your shoulder and a scarlet burning rune is left behind. You don't have enough time to figure what it means though as you can feel that already rather intense rut intensify. Soon you are slamming into the young man so hard and so fast that it shakes the whole bed, hell it shakes the whole house. The SLAM SLAM SLAM of the bed rocking against the wall could be heard from outside. The SLAP SLAP SLAP of your balls against the side of the bed just as resounding. You are huffing and panting and growling and snarling even more so than before. It is like an animal is taking you over which in many ways it was. You can feel your body beginning to swell and grow as your dick nipple is pissing cum down the young man's throat right into his stomach. You keep your clawed hand there fast against the back of his head; practically making him breathe your dick nipple as you continue to breed his ass. All you can think about is rutting his hole right now; making him pregnant with your seed. Nothing else matters right now except the rut and it is all you can think about. Again and again just fuck fuck fuck fuck. You're drooling and panting like a dog, your tongue hanging out and wagging as you stare mindlessly down at your mate as you bust another nut and another nut and another into his guts. You can feel the slop of it leaking back out of his ass and covering your balls in your own juices. The boy is already chanting again and you don't care, you're too busy rutting.
