The night Pyra and Mythra's return, Rex and Nia made decorations and cake. There was a banner that read "Welcome back!" and the cake was chocolate. Also, there were a few bunches of balloons. Both of them smiled at a job well done.

As Rex looked down, being naked in front of Nia aroused his penis was out horizontally now and getting thicker by the moment. It seemed like the same could be said about Nia, whose vagina leaked profusely while looking at Rex's penis. She giggled, "Look at how the celebration looks when Pyra and Mythra come home, Rex. This calls for a little celebration because of how well everything is done."

Rex concurred, "That's for true, my cute little pee-pee could use some groping right now."

Nia smiled at Rex's erection while sliding her index under it to give it a playful flick. After tugging at the scrotum, her finger went up to his navel. Then, Nia gave Rex a big hug, holding him like a little brother, she groped Rex's buttocks and smiled, "I like caressing your naked butt. You have a cute bare bottom."

That made Rex giggle, "Thanks. Your ass is nice too."

"I also really like your package."

Rex smiled, "I like feeling your fully nude body against my equally bare one."

Nia grinned, "Your skin is so smooth for a male, almost as smooth as my skin."

When Nia reached out and cupped Rex's round scrotum in her palm, he moaned. Leaning closer, Nia had her lips touch Rex's very gently. He could feel her breath as her hand rose slightly and she grasped the base of his erect cock. She knelt and took the head into her mouth very tentatively, closing her lips around the glans. Rex shuddered involuntarily.

Gently, Nia took Rex into her mouth, then let her lips play over the tip while she groped Rex's buttocks with one hand and let her other hand find its way up to Rex's stomach, poking his innie belly button, she paused to say, "Your navel is adorable too."

Suddenly, Rex felt like he would burst, Nia noticed and latched her mouth around his penis to collect everything that would spill out. He came in her mouth and she made sure to keep it from getting too messy, she spilled a few drops, but Rex collected them in the palm of his hand.

When Rex stopped climaxing, Nia sat down on her butt, then gestured for Rex to position himself between her legs and he very softly tickled the soles of her feet, making her giggle. Rex giggled back, "You have cute feet. They're so small and ticklish with adorable little toes."

It made Nia shake a bit when Rex licked her pussy, a tiny spasm in her taut abdomen made her shift her hips a little. As Rex's tongue swirled coyly and tantalizingly around Nia's pink folds, she could not help but arch while trembling a little and moaning.

With help from the naked boy, Nia felt her vgaina get wetter and wetter, sexual liquids seeped from her cunt and Rex licked it all. It wasn't long before Rex's face was drenched in cum. He then heard Nia whisper, "Lie down, please."

As Rex lied down on his back, Nia looked at him with a Cheshire cat smile. She grasped his erection and fondled it for a little bit before she slowly slid it back in her mouth. Nia began to move her head up to down, then rose and slid down again while running her hands down his hips and abdomen, Rex moaned, "Oh my god, oh my god."

After a while of playing with Rex's hips and flat belly, Nia wanted to pinch Rex's nipples while still sucking his cock. Rex could hear the sounds of Nia's suction as he repeatedly thrust into her mouth and pulled back. He pushed and pulled his dick into and out of her mouth rhythmically, Rex arched his back as he came, crying out and shuddering.

Now that ejaculating spurts of Rex's cum left him tired, Nia cuddled with him as she said, "Let's get some shuteye, tomorrow is a big day since Pyra and Mythra will be home by then."

Snoring was heard, Rex was already out cold.
