Scratching your head you decide you aren't used to the new body part and decide you would much rather have a vagina. In a instant you feel a warmth emanate from your balls as they shift and get sucked into your groin and position themselves in your body and then morph into ovaries. Next the skin that formed your ball sack tightens and then smooths over, then the feeling moves to your member and you moan as it recedes into your body and the area where your manhood used to be also smooths over leaving you temporarily genderless.
You then roar with ecstasy as a slit then opens up between your legs right above your asshole and forms itself into a fully functioning vagina with a womb which connects to your already formed ovaries. Feeling a damp sensation between your legs you feel yourself becoming increasingly hornier as you start to go into heat. blushing and grabbing your tail to play with in your hands you say in your head
"I must find myself a partner to make my husband so that we may reproduce and conquer this strange world i am now in".
You then think for a moment and for some reason you have the faintest memory of a woman that for some reason you have a intimate connection with and get a great idea. Waving your hands in the air you then summon your prized possession, your sistrum and with delicate grace you play the ancient instrument and are instantly teleported back to your apartment.
