While dinner passed without issue (if a little awkwardly due to an inability to cover Joseph's inhuman body and the fact that he barely fit behind the kitchen table) a new one soon presented itself in the form of a shaky cry for his sister. "Dawn? Can you help?"
She rushed into the room only to find her 8'4 brother staring sadly down at his old single bed. She facepalmed internally. Of course, he wouldn't fit into his old, tattered bed, he was twice the size of it and triple the weight! Gently, she put a hand on her brother's forearm. "Hey, Jojo, don't sweat it. I have an idea."
She pulled him away (or rather, he allowed himself to be led, there was no way she could move his gargantuan body by herself) to the linen cupboard, where she piled his arms high with as many cushions and blankets as he could carry (a lot). Then, she marched him to the lounge room. "Can you move the chairs and the coffee table out of the way?"
It turns out, he could. His new muscles weren't just for show, after all. They heaved and flexed as he effortlessly lifted sofas above his head, and curled armchairs as if they were paperweights. He even benched the coffee table with Dawn on top, much to her delight. After the showing-off was finished, they stood back to admire their handiwork. But the space they had just cleared was quickly covered as Dawn began tossing pillows haphazardly onto the carpet. At her brother's quizzical look, she explained, "Remember how, when we were young, we'd have sleepovers like this in each other's rooms? Well, we're doing that, but bigger." She patted his thick bicep, taking a slight pause to squeeze the dense muscle. "To match you. Now, come on, spread those blankets around and we should be covered."
Within a few minutes, the lounge room had been transformed into the perfect sleepover den. Dawn snuggled under the blanket and patted the pillows beside her. Joseph gave her a worried look. "You're sleeping here with me?"
"Of course I am, why wouldn't you think so?"
Joseph gestured down to his naked body, his massive muscles, and, most importantly his gargantuan cock. "I'm... naked, Dawn. I don't know if I'd be able to control myself."
"You will," she replied, smiling. "You haven't done anything since you grew, not even growing hard! I trust you, bro, I know you wouldn't hurt me. Now get down here!"
She grabbed his hand and dragged him down into the blankets with her. Then, with the other hand, she switched on their old nightlight. A starry sky projected up onto the ceiling. They lay there for a while in silence, just watching the stars go by.
"We haven't done this in ages," Joseph rumbled.
"Yeah. It seems like yesterday you were knee-height. I could scoop you up and swing you around."
"And I could crawl into my pillow fort and toss my stuffed animals at you!" Joseph laughed. "And then Mum would make us hot chocolate, and..."
"...rub our backs 'til we fell asleep. Yeah. I miss those times." Dawn yawned and stretched her arms. Joseph rolled over to look at her.
"You want me to give you one of her back rubs?'
She eyed his massive biceps warily. "Maybe when you learn how to control your strength a bit better. Here, I'll do you instead."
She rolled Joseph over, before grabbing some moisturizer to rub into his back. Then she got to work, running circles over his massive muscles, pressing her thumbs into his shoulder blades and gently massaging out any knots she found. It was only on the third round that she heard soft snoring coming from her brother. He'd fallen asleep. She let her hands leave his back, and just knelt and stared at the slumbering giant.
Then, she reached into her pocket and drew out the tub of ointment. Now was the perfect time to apply a little more, and should he wake up, she could easily pass it off as a massage. The only question, was where would she apply it?
