As teeth sank into his flesh, Preston only felt the pain of it momentarily before he let out a guttural moan, unable to stop the pleasure that coursed through him. It didn’t matter that this should’ve hurt him… it didn’t matter that his body was now covered in even more blood… No, what mattered was that he was seeing the darkness that radiated inside of Jack, the darkness that he created… and he loved it. Oh, how he loved bringing out Jack’s devilish desires, seeing the power that coursed through him. “Make me,” Preston defied, looking over his shoulder to where his son was standing, blue eyes darkened with a mixture of lust of challenge. “If you want me to believe that I’m yours, you have to make me… you have to claim me.” With the arousal in the air, Preston’s body fed from it and grew more powerful, and soon enough his tail had grown until it wrapped around his son’s slim waist while he pushed his ass back against Jack’s crotch, toying with him… teasing him. “Otherwise… I won’t believe it. Otherwise, you’re mine… and you always will be.”
Jack briefly wondered what either of them must have looked like, Jack covered in blood, hard and his eyes dark, dangerous and full of lust. His father, the same way. Naked, bloody and clearly going at each other. Jack sucked on the inside of his cheek at that defied rejection of what he wanted to hear. What he wanted to have soaked into his mind right now. “Oh, Father...” Jack drawled as he felt that tail wrapped around his body and felt that perfect ass press back against his aching cock. A hand moved up to grip the back of Preston’s head before he forced his fathers head against the desk again, pressing down tightly on his head to keep him there as his cock, slick with blood started to press into his father. He just wanted to hear him scream, at the very least. “You want me to claim you?” He snarled. “Like I claimed my brothers? Made them weak and fucking-..” Jack groaned as his cock pressed harder, further into his father as he held him down.
