Lucy

Three days after taking a DNA test online with your sister Lucy, the results arrived. To your surprise, the test says that you and Lucy aren't related. You find this news a bit sad, since you always thought that Lucy was your sister. The more you think about it, the less sense it makes, but the test doesn't lie, so it must be true. You notice that Lucy is acting a bit strange now, you assume that it's because of the results of the test.

It's now nighttime, you can't fall asleep, you're still thinking about the results. After trying to fall asleep for around two hours, behind the door of your room, you hear Lucy's voice say quietly: Hey... Are you awake?... You are, so you tell her that you are awake. You think that she can't fall asleep for the same reason as you. After this, she says in a voice that seemed strangely excited: Oh... Good!... Can you come in the living room, I need to show you something... You're not sure what she'll show you, but decide to accept her request. You get out of your bed, open the door to your room, and start walking towards the living room.

Strangely, the lights are turned off, so you can't see anything, you ask Lucy why they're turned off, and she says: Don't worry about it, it... it's for a surprise... Her voice seems shaky, as if she is hiding something. Just turn on the lights... when you're ready... You're not sure what the surprise is, but you can smell it. There is a strong, but pleasant smell near Lucy, it's a musky and humid smell, you don't know why it smells like this. You stop thinking about it, and make your way to where the light switch should be. You find it, and turn on the lights.

When you turn around to see Lucy, you are in shock. On the couch, there she is, completely naked. She is completely revealing her body, her legs are spread, showing you her massive balls, and incredible penis. You knew she was trans, but you had never seen her naked. You now understand why it smelled musky. Her breasts, they're beautiful, they seem so hard, and her nipples are so perky. The curves of her body are incredible, they make your body tremble in fear and excitement. You don't know what to say, while trying and failing to find something to utter, Lucy says in a lustful voice: Do you like what you see?~ She then touches the tip of her penis, spreading the precum on her tip, and she then licks her finger and tastes her own precum. The taste makes her moan, she then says: Come on... I know you want this... We're not even siblings anyway, so it's fine... When she said this, you noticed that her voice changed, as if she's hiding something.

She then starts touching her left breast with one hand, and she caresses her balls with the other. You're not sure what to think, only a day ago, you knew her as you're sister, but now... That test... Would it be wrong to have a sexual relationship with her? Lucy is awaiting you're response while touching herself, she clearly wants you to join her. Now's the time to say something:
