Open the door without clothes
From Create Your Own Story
You decide to just answer the door. You're siblings after all, you took baths together when you were little so why would this be any different? You open the door as Lindsay continues to talk.
"Mom said Aunt Amy called and she wants us to-" Your sister freezes mid-sentence at the sight of your naked body.
As she stares you stare back. Lindsay has always been an attractive girl. She's skinny but curvy, with gorgeous blonde hair and an adorable face to match. She's wearing a baggy, oversized T-shirt that goes down to her thighs and you can only imagine what's underneath that.
As you check your sister out, her gaze slowly lowers to your groin and stays there.
"She...she said um...that...she wants us to..." She stumbles trying to regain her composure but she's fixated on your dick.
