"Fuck yeah!" Tony couldn't move his head, but recognized the voice as his bother Alex's, obviously no longer asleep. Alex moved out of the shadows and in front of you, completely naked. "Now son" your father started, "if you're going to watch at least let me know so I can put on a show." Alex smirked before saying, "yes sir." You swear you see his penis twitch upon saying the word sir. In a matter of seconds, Alex's cock grows, doubling and then tripling its size. He's clearly been using the chronivac for self improvement, you think to yourself, he was smaller than you previously.
Alex inches closer to you, "like it slut, its double digits" he says with pride in his voice, "eleven inches rock hard." Maybe its because you cant move your head thanks to the chronivac, but maybe its because the desire you have to please the monster in front of you is genuine. You can't tell anymore.
"Wow son" you hear your father say from behind you timidly, "I didn't realize you were such a man." Alex let out a cruel laugh, "Yep, biggest in the family, the true alpha in this house." Alex stared your father right in the eyes as he said it, and to your suprise, Kevin looked away, finding a spot on the floor near his feet to concentrate on. "Now let me show this beta what a real man can do" Alex stated pushing your father to the side, lining his hips up behind your already sore ass.
Alex pushed his improved, massive 11" cock into you without hesitation. You screamed so hard internally, you swear someone must be able to hear it, but no one responded. Alex defiles your hole pump after pump, while your father looks on in pride, cheering him on. "Fuck yea boy show that bitch who the man is" and "Aww look, she likes it, now fill her with your alpha seed." Your ass felt like it was ripping in half, until finally, without notice, Alex let loose a torrent of cum into his brother, pulling out so that the squirts could spray out of his massive cock, into Tony's gaping asshole.
