You look at the time, based on what you know you only have a few minutes left until it's time to leave for the clinic. You realize you have to cum now or it'll be too late. You can hear your dad calling for you, it's almost too late.
You furiously rub your clit, so anxious to have one feeling of pleasure. Eventually you feel it, rushing through your body, a powerful orgasm. It feels so amazing, but only for a few moments.
When you're done you realize that this was really your last time feeling sexual pleasure. From now on you'll live a sexless existence. You woke up as a normal girl, and tonight you'll go to be genderless.
You start to get dressed. You realize that soon you wont need your bras or underwear, there won't be anything for them to hold. You start to cry a little but you while the tears from your face. It's time to leave.
