Surprised on a Spaceship

My friend's a man now, except for one very important part!We live on a multi-generational starship, traveling through the galaxy. My best friend suddenly transitions from female to male, and I've got to see it for myself! He's kept one memento from his time as a woman, female parts that beg to be satisfied the way nature intended. You'll be stunned by the steamy MM action in this space-faring tale!
