His only concern was if he could get back home. He started crawling through his mother's vagina, heading towards the exit. He could hear occasional moaning as he did so. His mom definitely tried to hold it in, but a few slipped through.
It took a bit, but eventually he made it to the bottom. As he climbed out, though, he realized. "Oh shit, I don't know how much time I have!" He set it to 24 hours... but since he did it in the morning, and slept in his mom all night, it was certainly almost up.
He didn't want to dwell on that yet, as he squeezed his way out of his mother's panties. Going to the edge of her chair, he jumped down all the way to the floor, taking a moment to get back up as he started to explore.
The classroom was well lit, with nice, baby blue walls. He was still behind her desk, so there was only way he could look out, unobscured. He knew this was his first time in her classroom, and he didn't even know exactly what grade it was, so he wanted to make the most of it. One thing though was that he couldn't even see the time; He had no idea how long he had.
He ran out from the side of her desk, and looked out upon the rest of the room.
