With Ty's inner turmoil he wished to go to his happy place... and that was what happened. A small lapse in judgement and Ty whipped his and Michelle's position in reality to a place he had set up many years ago.
Michelle looked around and asked "What? Where are we?" All she saw was the inside of a white blank cube of sorts.
Ty said "My happy place. I set it up awhile ago where I could just come here if I wanted and make anything I wanted and any scene without worrying about anyone... I'm not sure this is even in our universe."
Michelle just saw white wall and asked "So... how-"
"I just altered reality. I didn't bring anyone else here so user interface wasn't an issue." Ty said as he was beginning to succumb to his desires.
Michelle went from staring at a wall to staring out to a distant sparkling sea as she felt soft warm sand on her feet. She yelped in surprise at the sudden change and then felt a large giggle and as she looked down she saw her enlarged breasts... Well they were enlarged already, but now they were like a watermelon each on her barely clothed chest as she now had on a black bikini. Not taking her eyes away from her cleavage she patted her butt and felt her hands make contact with a much larger squishier. "Woah..." She said somewhat uncomprehendingly.
Ty was sitting on some combination of bed and beach towel looking a lot more fit with a cocktail in hand "Enjoying yourself?" he asked
Michelle chuckled and tried posing in some way with her bloated figure and asked "Is this what you wanted?" She then walked to Ty leaned in and started to snuggle up next to Ty, gave him a nice kiss, and then asked "You know what to do next?" presuming what Ty wanted. Ty nodded and gave her a peck on the forehead as the environment felt a lot cooler. Ty then sat up as he looked down on a confused Michelle.
Michelle looked down at herself confused. She had been a big girl... not just big but BIIIIG. Now she was just some preschooler in shorts and a pink shirt.
Michelle pouted and asked "I thought you wanted to..." and then her mind not knowing adult things very well tried rationalizing and describing what she thought had been going on. "...Get married!"
Ty chuckled and said "don't worry don't worry. We'll get married when you grow up." This was just the beginning of the day and Ty would use it to mess with Michelle a bit... He'd just need to remember to measure time somehow.
