It's a rainy day outside and Nasa and Cloud are discouraged from playing outside for today.

“Aw man… This sucks.” Nasa said. “I was excited to go to the park.”

“Me, too.” Cloud said, sighing sadly.

“You know, there's always some fun activities to do during a rainy day.” Sky said.

Thinking to themselves, they both went up to their room to play with each other. Soon after their rainy day activities came to an end, they decided to lay down. Cloud saw as Nasa's member started twitching.

“Um, Nasa?” Cloud said.

“What is it, Cloud?” Nasa asked.

Nasa saw as his yellow penis started to erect for no reason. Cloud watches this and then saw as his own penis went stiff.

“Wow.” Cloud said. “Watching you go stiff got me stiff.”

Soon, Cloud goes up to Nasa and the two place their dicks next to each other. Cloud started humping, rubbing his dick next to Nasa's while stroking them both at  the same time. After a few seconds of this, Nasa starts moaning.

“Oh, boy…” Nasa said. “I don't know how you get so much stamina, but…”

“That must've been from my father's side.” Cloud said, smiling.

The two then started cumming simultaneously and splattered each other with their own sperm. The two cubs lie next to each other, both sleeping as Armen aSkySky entered to check up on them.

“Aww, how sweet.” Armen said. “Both asleep after playing.”
