The sight of Athena sporting a large penis made Jon feel funny inside. He thought that he should be repulsed, but instead he felt strangely turned on.
Jon, Karyn, Zoe and Athena all started to feel strangely warm. Karyn and Zoe recoiled in terror as they felt their new equipment starting to throb and stiffen. Athena, who was apparently more sexually liberated, looked at her new cock with curiousity. She felt around and underneath it. Her vagina was gone, completely replaced by this large male organ and the heavy sack that swung beneath.
All four felt a strange urge to touch their throbbing cocks. Jon, Karyn and Zoe all tried to resist, even as their gowns tented out with their erections. Athena looked around, and laughed when she noticed that Jon's was less than half the size of any of the girls' members. She reached down and gently started to stroke and fondle the penis. She gasped again at the strange feelings that radiated from the organ - it was similar to rubbing her clit, but not quite the same. The feeling was much more centered on her groin than usual. She pulled the gown over her head, spread it on the floor, and lay down to start masturbating.
The sight of Athena's lithe body and perky, medium-sized breasts with their small areoles, sent Jon over the edge. He reached under his gown and started to stroke his own dick, watching Athena masturbate furiously but clumsily on her gown. Jon stayed silent, but Athena was starting to moan louder and louder. The sound of her voice turned Jon on more and more.
Soon Karyn and Zoe lost control as well, reaching down and stroking their new cocks curiously. Before they could get very far, however, they heard Athena cry out with a loud groan of pleasure.
They all looked at Athena as several spurts of white, sticky ejaculate shot out of her penis and spattered on her breasts and belly. Jon came a moment later, smearing hot, sticky semen all over the inside front of his gown. As they watched Athena lie panting on the floor, they noticed her large penis start to shrink rapidly. In a few seconds, her cock and balls had shrunk away to nothing, along with her pubic hair, leaving a tight, hairless pussy between her legs.
Jon cried out "Nooooooo!!!!" but it was too late. He felt his own, less impressive member starting to diminish, still hard from his ill-timed mastubration. He pulled off his gown and tried to pull and stretch his penis away from his body, but it was too late. Within seconds he stood naked, pulling at the new clitoris nestled in his bald vulva.
"It's not all bad," said Athena, consoling him, "it looks like your clit is really big for a girl."
