He bought the wrong purple pill

Blake and Alicia both watched his chest waiting for breasts to grow. They watched as his height didn't change. They waited for several minutes and they didn't see any changes at all.

"What the hell? Did the pharmacy rip me off?" Blake said angrily.

"That's weird." Alicia said. "I've never heard of the name brand stuff bought at a reputable store not working. Maybe you are immune?"

"This is bullshit. I'm going back to the pharmacy and getting my money back." Blake said pulling his shirt back on and heading for the door. He felt a pressure in his abdomen that signalled a slightly more urgent need than getting his money back. "Um... Right after I take a piss."

Blake closed the bathroom door, lift the toilet seat, dropped his pants and froze. He'd been about to grab his penis and pee but realized at the last second that he didn't have anything to grab. "Alicia!" he shouted.

Alicia barged into the bathroom a second later with a look of deep concern on her face. "What? What's the matter?" It only took her a second of looking at her friend to realize what the problem was: he had a pussy. She raced back to her room and grabbed the box the XChange pills had come in and rushed back to the bathroom. She found Blake there now sitting on the toilet.

She handed him the box which obviously neither of them had looked at closely enough before. "XChange Basic - Purple. For the gentleman that wants to discreetly try something new."

"Fuck!" Blake said tossing the box on the floor. "I've got a pussy for the weekend and I'm going to miss the slumber party. There is no way Liz's dad will let me in looking like myself. He's been pretty strict about the no boys thing for this party."

"Well... technically you aren't a boy right now. Maybe he'll let you come now?" Alicia said trying to be helpful and supportive.
