Mark hesitated. That was a tough decision. And he had not expected it too... So he pondered. What did he hate the most about being a gillwoman? Certainly having to take Amphibio's prick and getting pregnant, only to give birth afterwards. So remaining a gillperson but as a male would be it.
"I choose to be male again. That'll already be an enormous relief."
"Suits you. But you won't be able to lay eggs anymore, obviously."
"Will you accept pearls instead? Or gold jewellery?"
The witch nodded so Mark gave the witch his eggs. He hated being a mum anyway. The witch gathered her ingredients and told him to wait, which he did. This potion was long and complex to do. But after hours, once it was done, Mark seized the steaming wooden bowl and gulped it, ignoring the fact that it looked like a God-awful soup of roots, bug pieces and other vile ingredients. The taste was just as awful but he sensed his body transform at once. His boobs retracted. His hips became slender. He became taller. More muscular. His groin hurt and he felt something push outwards. He stared and saw it was a penis. Green and little and retractable in a sheath but it was there! A penis! An actual penis!
"Hi, little guy," he gushed with joy. "I've missed you!"
This was the honest truth. He panted, looked at himself and happy to be male again, if a gillman, he told the witch he'd gather the pearls, gems or gold she wanted and that he'd return then. He afterwards made his way back home. He'd tell Amphibio at once and inform him of his immediate departure. Ha! He'd take care of the damn kids now!
Upon seeing him, and getting the news, Amphibio was surprised and not happy. But he stayed calm. Not caring of how much the children cried, Mark took enough to live on his own and left. He was happy. But not for long. As soon as he had his back turned, Amphibio knocked him out with a branch and Mark woke up tied up under the hut. His mate told him that he'd dad enough, that the witch was bad news and that he'd summon a warlock who would hypnotize Mark and make him desperate to be a good submissive mate for him, albeit male. They'd abduct or adopt or buy any children they might want. Mark completely terrified. No! To be a gay gillman? To have only his penis as consolation? No way! But the warlock was going to come soon...
