Eating all that peanut butter made you thirsty, so you decided to get yourself a glass of water. You used your own telekinesis, although your powers were very weak, to levitate a glass under the tap and pour it yourself. You then levitated it back to your seat. It took some mental effort to do this since moving anything larger than a pencil took a lot of willpower for you, but it was nice that you didn't have to stand up. You thick bulky diaper and your large belly made it hard to get to your feet sometimes. In fact, sometimes it was hard just to walk down the hallway. You took a deep breath and a long drink of cool, clear water.
"Oh, you didn't have to get that yourself. I would've pour it for you." Rebecca said.
"It's okay." You said.
Rebecca telekinetically poured herself a glass of water... and telekinetically opened the freezer and got herself some ice cubes. It took almost no effort for her to do this. You always were jealous of her having so much more psychic strength and talent than you. Actually, she was physically stronger than you too... and a lot smarter... and was better at talking to people. Before the pregnancy, you had always been the small, scrawny, runt and she was always the tall, smart, and athletic one. Actually, you were still pretty small and scrawny, just with a bulging tummy now.
Sollos could hear all your thoughts of self-pity and jealousy. Oddly, he seemed to be on your side.
"Get a grip, woman! She may be better than you on the surface but there's one thing she hasn't got!" Sollos said.
"What? What could it possibly be?" You asked.
"She isn't blessed to be the vessel for Sollos the Magnificent!" Sollos said.
Sollos manifested his powers in a way you had never seen before. He transmuted the water in Rebecca's cup into prune juice. Rebecca spat it out, immediately recoiling at the terrible taste, putting a purple stain on tablecloth.
"Oh... Oh crap, what was that?" Rebecca said.
Sollos laughed and giggled.
"Maybe I should make her poop her pants too, hm? Wouldn't that be a joy?" Sollos said.
"Sollos, no! That's bad, very bad! Don't be mean to your Aunt Rebecca!" You scolded.
Rebecca looked at your tummy with a puzzled expression.
"Did... did he do that?" She said.
"Yeah, I think so." You said.
"I didn't know he could transmute things now." Rebecca said.
"Neither did I." You said.
It was becoming increasingly apparent that Sollos would one day have god-like powers. You hoped he would use them responsibly, but somehow you felt he would be a tyrant. It scared you, but you kept that kind of thought in the back of your mind. Sollos heard this thought, however, the fear that he might on day become a tyrant. He felt bad hearing this. He was a selfish brat, but he wasn't evil, or at least he tried not to be evil.
"Fine, I won't make Aunt Rebecca poop. I don't want to be evil, mother, I only want to have fun. However, I see a vision in the future, and I know that you will have to void your bowels in three minutes. If you don't want to soil yourself, you best get to the toilet now." Sollos said.
You smiled. It meant a lot hear him call you "Mother" for once. He didn't do that very often.
"Sollos feels bad about turning your water into prune juice. I think he's sorry." You said, trying to get to your feet.
Your sister helped you up while telekinetically wiping up the spill.
"Oh, well, he's forgiven, I guess, if he knows it was bad to do that." Rebecca said.
"I have to hurry to the bathroom. I think I have to poop." You said.
Rebecca nodded and you began waddling toward the toilet. You were only a couple steps away when it hit you... you were too late. A stinky mess escaped your butt and spread over the back of your diaper. You groaned. Rebecca patted you on the shoulder.
"Didn't make it, huh?" She said.
You shamefully closed your eyes and nodded.
Rebecca telekinetically lifted you up in a reclined position, like she was carrying you like a baby.
"Come on, Tina, let's get you cleaned up." She said.
She scrunched her nose.
"Ooh, that's some stinky doodies." She said.
You blushed, totally embarrassed to be talked to and carried like this.
Rebecca set you down on your back on the changing mat in the bathroom. It was where she usually changed Jenny's diapers, but she kept a large supply of your diapers there too. Rebecca removed your messy diaper and took some wet wipes to clean your butt. You had really messed yourself good. While you appreciated that she was there for you and helped you out with stuff like this, you thought this might be a good time to tell your big sister how she made you feel, how you were so jealous and wished you could be like her... but maybe it was best kept quiet?
