Older sister teasing me

My sister and I recently hung out over at her place. We usually chat and drink for a few hours. We always had an interesting relationship and pretty open. I wore tighter pants so my bulge could be easily viewable with a nice print. I noticed her constantly checking it out the or we if her eye and as she would turn or bend over. which was hot. As the night carried on she started talking more sexual asking what my kinks are and telling me hers. I had mentioned she looks really good in the color green. Later in the night I mentioned needing to shut my eyes for a bit before I head home, had to be around 12:30am. I noticed once I went and sat on the couch and turned lights out she stayed in the kitchen with the lights on cleaning up. She even changed her top to a very loose green button down with no bra. I could see almost all of her boobs falling out it was unbelievably sexy. Her nipples were so hard. I couldn’t resist pulling out my cock and stroking. I think she noticed what I had been doing and giving me really hot views. She went to bed eventually and I headed home. We texted the next day as if nothing happened. I’m so curious if she found that night incredibly hot and wanted to wear something sexy knowing id notice. 😮‍💨🍆
