Halfway back to class, Mikey got the sudden urge to pee. "Miss Grant, I have to go to the bathroom." She smiled down at him knowingly. "Need to adjust your bra? Sure, sweetie. Go into the bathroom right outside of class. I trust you to come back afterwards." Mikey simply nodded and ran to the bathroom, slowing down after a few strides. Even with the bra, his boobies... breasts... pulled on his skin and hurt when they jiggled.
He headed for a urinal as soon as he got to the bathroom, and struggled to unzip his pants; eventually he just had to squat, rest his boobies on his knees and pull his pants down. He was halfway through peeing, unable to hold it, just letting it fly, when Benny spoke up from behind him. "Could I see them, Mikey?"
Mikey just stood there, thinking for a minute. "If you pull my pants up, you can see them." He heard a gasp behind him. "For real?! Sure!" Mikey stood still as Benny grabbed his pants and underpants and pulled them back up, then turned around carefully so he didn't set his boobies jiggling around again. He grabbed the hem of his shirt and pulled it off with some difficulty, exposing the lacy pink bra he was wearing.
"Hahaha! Where did you get that?" Benny pointed and laughed, as any boy will do seeing another one wearing pink. "Miss Grant gave it to me. She was wearing it before." This wiped the grin off of Benny's face, replacing it with awe. "Whoa... you have her boobies, and now you're wearing her bra? That's so weird... it's kinda cool!" Mikey sighed at Benny, irritated now. If he thought it was so cool, why didn't he have them instead of Mikey?
"Do you know how to unhook it? I wanna see 'em! I'll never see Miss Grant's!" Mikey shook his head, and his face burned red as he spoke, but a deal was a deal. "Get behind me and you can unhook it, I can't reach back there." As Benny ran behind him and started fiddling with it, he whispered, "I wish the next thing Benny wondered turned true..." The rock burned in his pocket for a moment, and he suddenly realized why the wish came true!
As Mikey was about to try to reach into his pocket to get the rock, Benny finished unhooking the bra, letting it fall onto the floor. The released weight almost made Mikey fall flat on his face - well, on his boobies. He stumbled a little bit, then stood up straight as Benny gawked at him, making him feel like a piece of meat on display. "Wow... they're perfect! They look just like Miss Grant's, huh? The same skin color... big pink nipples... they're so hot!"
Mikey didn't agree; the huge boobies were big on her, and they looked absurd on him, not to mention he was having trouble standing up with their weight attached to him. They sagged just a little bit, and as big as they were on his chest, they pushed together naturally. His thoughts were interrupted by a sudden rush of pleasure as Benny rubbed the points - nipples, he reminded himself. "Benny, sto...aaahh!"
He trailed off into a yell as Benny kept playing with them, his winky was really hard now, and after about ten more seconds, he came and lost his balance, falling to his knees and shivering as the bottoms of his boobies touched the cold bathroom floor. Benny stopped a moment later, staring at Mikey. "Wow... that was kinda like touching your dick, huh? I wonder what that felt like..."
Suddenly Benny lost balance as Mikey was recovering, and he screamed as he fell to the floor with two massive globes of flesh under him. After a moment, Mikey knew that Benny had boobies that looked exactly like his and Miss Grant's, because of the wish. "What the hell happened?! It feels like my shirt is about to break open... ahh!"
Benny screamed again as he looked down to see his view obscured by his shirt, pushed out by two huge orbs of flesh. Mikey picked his own shirt up off the floor and put it back on after some difficulty, and walked out as fast as he could without much pain, carrying the bra he knew he couldn't put back on.
