Your younger sister, Marissa
From Create Your Own Story
"What are you doing?" Marissa looks beyond shocked. She looks really disgusted.
"I, ummm, I'm sorry, I just came to see you and, I, ah fuck..." you give up and sit on her bed.
Marissa recovers from the shock and starts laughing.
She laughs for a good minute before being able to speak. You star getting annoyed.
"Were you licking and sniffing my used panties?" she laughs again, looking down at you sitting on her bed.
"I didn't mean to. Fuck, I..." you begin explaining, not knowing where you're going with this.
"Language, please" Marissa corrects.
"Sorry... but I saw them. I didn't know they were panties. They looked so nice and when I picked them up I smelled something and, listen, this'll sound weird, but is was something animal in me. You must, excuse the wording, be fertile or in heat because its like a drug to me. I dunno. I'll leave now..." You drop the panties and leave.
You glance at Marissa and see a contemplative look on her face. You continue to your room.
During the day you decide you need to do something ...
