Kneeling on the floor, Harry was gagged and his hands were bound behind him. His pathetic little cock was similarly bound so that he couldn't come without permission.
Although he should have been disgusted, his heart was actually pounding from the excitement brought from the scene before him.
Sitting on his marital bed was none other than Draco Malfoy, naked from head to toe with his enormous cock standing proud. Behind him, Harry's equally naked wife was kissing her lovers neck while she rubbed his chest too. Harry's tiny dick throbbed painfully at the sight of his wife loving another man; a true man worthy of the name, not a little sissy with a small dick like Harry. His beautiful wife deserved a man like that to satisfy her like Harry never could. He knew that now.
Of course that was true also for the rest of Harry's family. His children, now all at the age of consent, were on their hands and knees between Draco's spread legs and with their butts toward their father. Lily and Albus were kissing one of Draco's feet each while James, the oldest, shamelessly sucked on the alpha male's cock.
"Swear yourself to me," he said in a commanding voice. "Become my fuck-toy like your mother already is."
"Do it, James," Ginny prompted between kisses, "Join mommy and be a slut with me."
"I swear," James said with a sigh. "I'm forever your, my Master."
"Lily, Albus, you too," Ginny said sultrily, "Join your brother in servitude for the rest of your life."
Lily and Albus glance at each other and after a nod they both crawled at James's side before Draco's cock.
"Master," Lily said kissing the tip of the huge dick, "I am forever your to do as you please."
"Master, I, Albus Severus Potter swear myself to you for all of eternity in mind, body and soul," Albus promised, nuzzling his face against Draco's balls with unending affection.
"Well said," Draco approved. "Receive now my seed and be born anew as my slaves."
He forcefully grabbed Lily's head and released his seed into her pretty mouth, switching then to James and finally to Albus.
"From now on you are mine. No longer persons but tools for my pleasure. If you accept this fate swallow my seed."
All three of them gulped down mouthful of their Master's nectar without hesitation, opening their mouth and sticking out their tongue as proof of their unyielding devotion.
They were now and for all of eternity Draco Malfoy faithful fuck-toys.
