"I want... to be...I want to be a sphinx," you decide and blurt out.
Andy smirks upon hearing your choice.
"A sphinx? Are you sure?" he smiles.
"Yes, I am," you say softly.
"That's a rather unusual choice, you know."
You mumble something. But you do not care. A sphinx is an odd choice, it is true, but it is the most sensible for you in this moment. You don't really want to become a nameless soldier in an army and die in combat after ruthless training and living in a camp without much comfort or hygiene. Or women, in all probability too and men aren't really your cup of tea. As for being a mount, it does not seem much better. You would have to feast on hay or greenery and stay in a paddock most of the time. And die in combat too and take orders from whomever, might ride you. Carrying an owner, even as a pegasus, sounds just awful. As a flying horse, sure, you could dash across the rainbows and skies and clouds but you would not be free, attached to a bridle all day long. What would being the point, chained to a post or stuck in a paddock all day long? Giants are not renown for their intelligence and as for being a Cerberus, the idea of possessing three heads is enough to make you want to vomit. Ugh! No way! Satyrs seems to have a nice life of eating and mating but they are ruled by their pheromones and are easily manipulated through promises related to sex. Moreover, the idea of being attracted to not only women but men is not appealing at all and you'd be molesting, raping and harming people. Not great for them, or you in the end. A sphinx sounds much better.
"I know," you murmur. "That's what I want, though."
"If that is what you wish," smiles Andy.
He spreads his hand over your head and you feel a shower of magic wash over you. You feel you body change. Fur starts to spread over your body, from your chest down. A long tail sprouts from your backbone and your spine elongates. You can feel retracted claws sharply replace your nails and toenails. Your dentition becomes fanged, infinitely more than before. Then two stabbing pains erupt on your shoulder blades. What can that be? Your body is transforming into a lion's but what can those pains possibly be? You turn your head over your shoulder and glimpse wings, wide eagle wings, spreading from your body. Wings? Since when do lions or sphinxes have wings? Then you feel your chest expanding. But to your horror, not with pectorals. With boobs. Round and shapely, quite adorable in fact for any man, breasts are now jingling and bouncing happily. You cannot even scream because you then feel your face change, your lips getting plump and your eyes almond-shaped and wide. Your features are much, much finer now. You can also feel your hair getting longer and brush past your shoulders. And as a finishing touch, your groin indicated new pains. Appalled, you stare at your own crotch with horrified eyes. Your testicles get swallowed by your own flesh and once inside, you can feel them rearrange themselves on the sides of your lower stomach. Ovaries. They've become ovaries. Which means... And indeed you can see your penis vanish as it became a vagina, womb and birthing canal. You did not even get to say goodbye and the last remnants of your male genitalia were a clitoris, labia and a hole meant to welcome a man's penis and hold and expel a baby. Ugh! Disgusting! You turn to Andy, furious and certain to have been swindled.
"What have you done? I am no sphinx! I am a woman with a lion's body and the wings of an eagle? What is this farce?!?!" you roar in a feminine voice that you must admit inwardly is very sultry.
"I have indeed changed you into a sphinx," calmly says Andy, unfazed. "You must have been thinking about the Egyptian sphinx, a lion with a man's head. But in Greek mythology, the sphinx, or sphynge, is always female and has wings upon her back. It adores asking riddles too. You cannot really be a mount, but you can serve fine in an army. I am sure we can find you some things to do. And let me reassure you, your female parts are rather gorgeous to behold."
You are outraged. Blast those mythological differences! You wanted to avoid the worse and you are now female! One with a face, hair and boobs indeed worthy of a supermodel's, as you gaze into a pool, and likely to attract all males around! Of course Andy did not tell you anything and assumed you'd get the sphinx creature wrong! You growl and curse at your ill fortune, pawing the ground in fury while Andy just smirks smugly at your rage.
