The next hour came as Jen was in girls' gym class. They were getting prepared for a run when she coughed up the next pill. Thinking on her feet, she slipped it into a bottle of water, and a brunette with glasses named Sarah picked it up and drank it.
At first, nothing seemed to happen to Sarah, but then she offered it to her friend Natalie, a girl with long black hair. She accepted the drink, but after the first sip, the two merged together into a two-headed conjoined form. Sarah helped put the cap back on and Jen got a detailed look at their body: Both heads sat next to each other on their shoulders, with Sarah on the left; They had four arms, two on each side, and each girl controlled both the arms on her own side; A bulge in their gym shorts showed that they had a penis now; their breasts seemed to be their B- and D- cups put together, forming F-cups on their new chest.
Jen thought she was off the hook with a comparably mild mutation compared to those earlier today, until another girl, Ashley, asked them for a sip too.
