"You're right, I should've..." you answer. The queen smiles at you warmly.
"It's all right, you can still have another chance" She explains. "I can make this your usual form"
"Er... actually, would it be possible to be male again? I miss my old self" you explain at which the queen giggles, slightly.
"Miss your little friend?" Escapes from her still giggling mouth "As you wish". With that, she passes you a conch shell and asks you to blow into it. Your breast fall away into your previous masculine chest and your arms, shoulders and face regain their previous features. Even your tail takes on a more muscular form and lastly your genitals invert, restoring you previous penis. You inspect your new form with gratitude as you roll and turn in your now more familiar yet stronger form, looking and feeling every part.
"Thank you, thank you so much" you gasp in pleasure and the queen gives you a smile of recognition. You are then sent off and released to enjoy new life as a merman.
