They had been walking for barely twenty seconds before Mikey was suddenly struck by the urge to pee. "Miss Grant, can we go back? I need to go to the bathroom!" His new BREASTS were simply jiggling a little bit as he walked now, owing to the new bra around his chest, and he felt a great deal of weight leave his shoulders since they were safely suspended rather than just hanging.
"Sure, sweetie. Just remember to sit down, okay? Your mommy told me you have trouble peeing otherwise." He looked up at her alarmedly; he was going to have to sit like a girl from now on?! "Oh, don't worry, honey! I won't tell anyone. Just go into one of the stalls. I'll wait in the restroom until you're done." She opened the door once again, gesturing to the row of stalls against the wall. Mikey caught a glimpse of himself in a mirror, frowning at the way his... his? bra showed clearly through the white shirt he wore, and the design on his shirt was distorted by his boobies... breasts.
He sat down on one of the toilets in the stalls, having to climb up it, jostling his boobies painfully on the wall as he did so. "Ow!" The pain was overwhelming for a moment, almost causing him to fall off of - or into - the toilet seat. "Are you alright in there?" It took him a moment to come up with an answer. "I just hit one of my... thingies... on the wall."
He could almost hear her wince, as she spoke. "Ouch... I'm sorry, honey. Be careful, they can really get in the way!" Like he needed her to tell him that. After some struggle, he pulled his pants off enough to expose his parts, once again becoming aware of the cold rock against his skin through the hole in his pocket.
He started the stream early, unable to hold it in much longer, and struggled to reach his winky to aim, but his boobies kept getting in the way. Every time he looked down all he could see was his shirt pushed out by twin mountains of flesh, but he heard tinkling on the floor and on his pants, blushing as he heard that. Once the stream ended, he tried to hop down lightly, but he lost balance and fell on his side, pushing the stall door open and landing partially on the huge orbs of flesh hanging from his chest.
The pain and shock from falling on them made tears spring to his eyes, and before he could stop it, the tears were steadily flowing. "Oh, honey! That must have hurt so much!" Miss Grant knelt down and scooped him up into her arms, kneeling and hugging him, their identical breasts mashing together. He cried it out for a short while before extricating himself from her arms and trying for a minute to pull his pants back up before Miss Grant did it, taking care not to touch the wet front.
"Come on, let's go back to class. I'm afraid the nurse doesn't have any spare pants. Just try to hide it, okay? The kids won't tease you much, I'll watch." She pulled him up from the ground and walked slowly out of the bathroom, motioning for him to follow as she headed back to class.
