I'm your sister's friend and am staying at your house for a bit while she and I work on a project together. You come into my room as I'm unpacking my bags. We make some small talk as I unpack and my shorts shift to expose parts of my pussy. You can't help but stare. The next day as I'm making some food in a thong, you come out to the kitchen. I know at this point that you're into me so I decide to play on it a bit. I sit at the table and make small talk as I eat, showing off my panty covered pussy. After this, you catch me in the laundry room putting my clothes in the wash. Finally, I hang out with you in the room I'm staying in. I decide to play with you even more and show off my bare pussy. I confront you a bit, asking that you that you keep this quiet. I lay there and tease you some more before your sister asks me some questions. I decide I'm going to keep teasing you, as long as you don't ruin it.
