Armen was out on his own outside. He was laying down on the grass, staring down at his own penis. He watched as his grey member stiffened, his tail wagging to do so. He begins wrapping his tail around his stiff cock and starts stroking it. Soon, Atreus shows up to the backyard. As Armen was masturbating, Atreus looks at Armen, looking to have sex.

"Oh, you're making me kinda horny here." Atreus said, blushing a bit.

"Atreus, my naughty child." Armen said in a naughty tone. "You wanna go inside me?"

"Well... okay." Atreus said.

Armen twitches his penis in an attempt to make Atreus hard. This worked, as Atreus enjoys every moment of it. The grey cat saw his moaning herm son's member get stiff.

"You're getting hard, and already you're moaning?" Armen said. "You haven't even entered my hole, yet."

Armen gets on his stomach, showing off his butt.

"Go on, my kid." Armen said. "The door's open."

Atreus then inserts his dick inside of Armen. He then starts humping his father. Armen moans from the humping he is getting from his son.

"I'm gonna cum." Atreus said.

"Already?" Armen said.

Atreus cums inside of Armen's butthole. He then pulls out of his grey brother, and presents his clit.

"Now try me." Atreus said.

Armen slides his dick inside his herm son and then proceeds to hump him, stroking his dick to milk him even further. Meanwhile, a mature egg was floating down on Atreus's fallopian tube. Armen is about to cum as he humps faster.

"Get ready, Atreus." Armen said.

Armen cums a huge load inside of Atreus, then pulls out of him. Armen's sperm fertilizes the floating egg inside of Atreus. Armen was a little paranoid that he might get mad at him for impregnating his own son. Atreus assured him that he had that happen to him before, seeing as he gave birth to his grandson Alfred. 9 months later, he gives birth to a healthy baby boy by the name of Xavier. Seeing the little child gave him a sense of satisfaction and pride for his new son.
