"Take it all in baby boy" Rick grunted. He slowly shoved his member in Mortys mouth.

Morty took in as much as he could gagging and whimpering the first time Rick hit the back of his throat. He pulled back a little but suckled hard and fast wanting the milk from his bottle.

Rick let out a low moan as his head fell back. "G..good boy!" He cooed.

Morty made more and more happy noises as he pleasured his Grandpa. He nursed more and more loving the feeling of having Rick's cock fill his mouth.

Rick gently guided Mortys head down on his member. "G...good boy!" He moaned.
