As Jeff waited, Diana made her decision. "I know! Teehee, I'll put you somewhere that you'll always be near me! That way, even if I'm naked, I can always check in on you!"
Jeff was confused. "And... where would that be?" He knew of a few locations; Her mouth, somewhere in her butt, up in her urethra, even in her ears.
Diana's response made Jeff even more curious. "You'll just have to wait and see, Teehee! But first..." Diana walked over to turn on the shower. Jeff didn't know if she was doing that for him, or for herself.
It didn't take long to learn, as she took her clothes off, with her diaper on the toilet. She then picked Jeff up, tucking him neatly inside of it.
Diana stood there, thinking. Jeff didn't like the look. She then turned around. "Hehe, I may as well do this as well..." She took Jeff out of her diaper, before stepping in the shower, still holding him.
That's when he realized. He was forced to share the shower with his little sister. "Diana, I don't think this is necessary..."
Diana looked at him as she was getting herself wet. "What do you mean? Why would it matter if it's necessary?"
Before he could speak again, Diana lifted him up higher; She positioned him to where he was peeking out of her mouth, as she grabbed the soap to wash herself.
As she washed, Jeff was stuck looking down. He couldn't see her vagina from this angle, as her stomach blocked the way, but he had a decent view of her yet-to-develop breasts.
She finished off with the soap, taking Jeff out of her mouth. That's when she chose to use the soap on him as he struggled. "DIANA! Stop!" "Hold still!"
After a few minutes of fighting, Diana finished. She stuck Jeff back into her mouth as she worked on her hair. "Why me..."
----- After the shower -----
Diana finished up, Jeff still complaining about sharing the shower. She took him out of her mouth as she stepped out, before grabbing the towel.
Jeff didn't know if it'd get worse, but it did. Diana put him against her chest as she wrapped the towel around herself, drying off. Thankfully for him, it didn't last long.
Diana set him down, and put a diaper on. That's when she spoke again. "Hehe, now you get to see where I was talking about earlier!"
She picked him up, before opening the waistband of her diaper. He was prepared to be dropped in...
...but, she didn't drop him. She reached in, and separated the lips to her pussy. Then she reached further, shoving Jeff inside of her vagina. "There you are! Nice and snug."
Before she moved, however, the walls on the side of her vagina pulled Jeff in. He tried to hold onto the side, as Diana watched curiously, worried but confused.
Jeff was pulled inside, as he began screaming. Diana could feel his screams vibrate within her, with a pleasure she didn't know. However, she couldn't get past the worry; Her brother was pulled inside of her, and she can feel as he's pulled back.
Within the darkness, Jeff could barely see. He only knew he was moving backwards, pulled by the walls. He felt himself get pulled through an even smaller space. Then, he stopped, the fleshy walls changing. He was all the way in.
Diana wasn't sure what was going on within her. She could feel Jeff for a moment, before the feelings disappeared. Jeff was suspended within her womb, the cord connecting to him.
Jeff wasn't sure what was going on. He felt like he was floating, but also attached to something. He wasn't sure what was going to happen.
Diana, also unsure of what just happened, finished off in the bathroom, going to bed with the strange situation in her mind...
