At home, Rex and Nia were naked in the shower. He was so aroused because showering completely naked with Nia behind him. She was looking at his naked butt while she soaped him up. Nia thought Rex's bottom was adorable.

Being naked, Rex liked showing his erect cock to Nia and put his hands on his hips. It made him smile as Nia's eyes stared widely at Rex's exposed body and he asked, "Do you like what you see?"

In response, Nia grinned, "I always do, I especially like how you have no hair down there, so I can see all your body parts clearly!"

Hearing all that while being on display for Nia was having an effect on Rex, whose cock started to enlarge and he knew there was no way she was not going to notice. Soon, it was pointing up right up at her at full attention. Amazed, Nia said, Oh my God, look! You're getting a boner! It's so stiff!"

Rex became even more excited at being fully exposed as he wondered what to do next, "Perhaps stroke it a little? Play with my testicles? Twerk?"

Before realizing it, Rex started jerking off. When he did, Nia started to giggle and touch her breasts while Rex was getting himself off. She was soon eagerly walking towards Rex and turned him around to see his ass.

Nia had Rex get on his hands and feet so he could perform the downward dog. His naked bottom was in full view and Rex could see Nia upside down wide-eyed from under his butt as he heard her gasp before she covered her mouth with her hands. Giggling uncontrollably, she squealed, "Oh my God. You're totally naked and showing your cute butt. It's still adorable as always."

Rex waited like this, feeling Nia's eyes on him as he watched her looking in at him. All Nia did was stand, look and thoroughly enjoy the view.

Because Rex was flaccid due to temporarily ceasing masturbation, it took several sexy comments from Nia to cause Rex's erection to return. Now that Rex had regained his raging erection, he smiled as how it was dangling from underneath his asshole.

In a minute, Rex stood up straight with his stiff member springing up and pointing upwards until the tip was aimed at Nia's belly button. It danced up and down when Rex wiggled his hips and contracted his stomach muscles. With both hands on his penis, Rex fondled himself again as he stayed like that, fully exposed, heart pounding as he watched their reactions and listened to the excited giggles from Nia, "I like how you've got a boner!"

Rex giggled, "Guys can't help when they get hard. It happens all the time to me."

"You look so nice down there. I just want to touch those balls right now. I want to play with your testes and your hard cock too!"

With that, Rex said, "Well, Nia, are you just going to stand around and watch or actually touch my naked penis?"

Nia reacted by finally starting to stroking Rex's shaft, the naked boy felt like he was in heaven with her caressing his private area. Seeing her reasonably big and perky tits as well as her neatly trimmed bush with pubic hairs that were the same color as the hair on her head turned him in even more.

While groping Rex's shaft in her hands, she duplicated the motions Rex had been doing before placing one of Rex's hands on her breasts to grope them both.

A minute later, Nia reached around and cupped Rex's firm bottom with one hand while still having her other hands continue to fondle Rex's penis. She asked, "Are you going to cum soon, Rex?"

Rex smiled, "Given the way you're touching me, it won't be long."

"Good."

Being way too involved in the feeling of Nia having one hand on his penis and her other on his ass, Rex had lost track of time, but he knew it had been at least five minutes since she had started stroking his cock and buttocks.

When Rex knew the end was near, he announced his impending climax just as he exploded in a very intense orgasm with long ropes of cum landing on Nia's chest and belly, effectively coating her upper body. Her fingers were coated from his orgasm too. Happily, Nia exclaimed, "Oh my, that was a lot!"

As Nia started licking some of Rex's cum from her chest and stomach, she seemed to enjoy the taste. Once she was cleaned up, she placed Rex's softening cock between her lips, sucking gently and licking him clean. Nia said, "I should have asked you to cum in my mouth."

Once all of Rex's semen was washed off and went down the drain, he and Nia soaped themselves off and rinsed before exiting. As they both dried off, Rex mentioned, "Let's not forget plans for the welcome home party. Pyra and Mythra will be back in a few days."

"Don't worry. We'll take care of it first thing tomorrow."
