Two on my cock.

Karin, it turned out, was more than happy to come down and watch a video. While our mom's intensity was off-putting she was happy to see me apply myself. Two minutes later she was chanting to the program while I fucked Mommybot in front of her soulless eyes.

"Yes Master, this **** stands ready." Her white eyes and blank face looked even sexier than mom's, knowing that I destroyed so much potential just so I could have another mindless cocksocket. Killed off a genuis intellect so I could fuck her face. Destroyed my sisters life so I could have another cumdump, made it just that much sweeter than breaking my Mother.

"Adopt Karin personality" I ordered. "Strip and prepare for titfuck."

"Yes Master. Strip..... Titfuck..... I cannot resist, I must obey." She smiles and quickly disrobes showing me an amazing young rack somehow defying gravity dispite their size. She thrusts them out and me and spits between them, making a slippery tunnel. She than faces Mommybot and allows her to spit in her cleavage too. They kiss, their programing telling them the incestuous display will arouse and excite their master. After several minutes they both pull back. Mouths full of each others spit and together they drool it all over Karinbot's dirty pillows. "Come on big bro. Moms got me nice and wet for you Master."
