You grab some toilet paper and dab off the last few drops of urine clinging to you. After dropping it into the toilet you stare down at your recently transformed groin. It's not the first pussy you've ever seen, but it's the first time you've ever seen one from this angle. It's also the first one you've seen with this much hair around it; most of your previous partners had either trimmed or shaved their pubic hair.
You gently brush your fingers through your pubic hair and caress the lips of your new sex. It's harder to see what you are doing than you'd imagined it would be, so you close your eyes and just explore with your fingers. You quickly locate your clitoris and try giving it a rub but it is too sensitive and stimulating it directly is almost painful. Moving on, you part your labia and slide your finger along your moistening slit. reaching the edge of your vagina. hesitantly you begin to slide your finger in.
The pleasurable sensations your feel as your vagina is penetrated for the first time are hard to describe. It doesn't really compare to anything you've ever felt as a man. You slowly slide your finger out and then back in, a little bit deeper this time. You do this a few more times until your finger is buried all the way in your vagina. A few more strokes and you decide to try adding a second finger. With two fingers moving in and out of you, you feel really full and even slightly stretched out. You consciously decide not to try three fingers... at least not this time.
You continue your masturbation for a few minutes and can feel a sensation building within your groin. You know it's an orgasm and you're guessing it's going to be a big one.
