You are sitting in the lounge, watching ${1. favourite TV show} while you relax with a glass of orange juice. You hear movement upstairs as your ${2. is your sister older or younger?} sister leaves her room. After hearing another door upstairs open then close, you shrug.
She's probably just going to the bathroom, you think to yourself.
A minute or two later you hear movement upstairs again, your sister returning to her bedroom, most likely.
You shrug again, not really caring what she's up to, then take another sip of your orange juice and turning your attention back to the show you're watching.
After about ten minutes, you hear a loud cry of pain from upstairs. You drop your glass and rush upstairs to see what happened.
Throwing open the door to your sister's room, you find her naked on her bed, a dildo lying next to her with some blood on it.
"What happened, ${3. sister's name}? Are you hu- Why are you... naked?" You ask, shocked as the sight before you finally sinks in.
"${4. character.name}! Why didn't you knock?" Your sister asks, tears in her eyes.
You close her bedroom door and slowly approach her. Your sister has a ${5. description of sister's body (slim, toned, chubby, etc)} body with a ${6. sister's chest size} chest.
"I-I heard... you cry of pain. I came here to see i-if you're alright..." you say, still trying to make sense of what you're witnessing. "Is that... mum's dildo..?"
Your sister looks down, slightly ashamed. She covers her chest with one hand and her crotch with the other. She looks at you, then the space next to her on the bed, as though she wants you to sit next to her.
With a sigh, you sit down next to your sister, who then leans into you. You put your arm around her and kiss her on the forehead.
"Yes..." she says, "it's mum's dildo."
"You've never done it before?" You ask.
"No... I'm a virgin. I-I never even used a dildo until today..." she replies. "I pushed too hard, broke my hymen..."
