Wet Panties

A couple months ago I started to notice that my panties were often wet hours after I threw them in the hamper after showering and working all day. I didn’t think much the first time it happened but when I did laundry a few days later they were wet and appeared to have cum in them. The only thing that made sense was that my stepdad shot his load in them. I got instantly wet and couldn’t get the thought of him jerking off on my pussy - indirectly. I licked them and the taste was intoxicating. I’ve tasted my own juices on my boyfriends cock and on my own fingers but the saltiness of his cum and my juices made me almost orgasm on the spot. I even put some water in the crotch and squeezed it in my mouth. Oh my god!!…I immediately went and finished with my vibrator.
The next day I woke up and rubbed my pussy thinking about his cum and wanting to get him to shoot his load down my throat. I creamed my panties and left them on my bed instead of the hamper. All day I thought about the g*ft I was hoping to get when I got home.
He gets home from work about an hour before I do and my mom gets home after me. This gives him time to do what he wants for awhile. When I got home I went and got to my room and my panties were on my floor with a huge warm and wet load in them. He must have just shot the load when I pulled in. Instant wet. I ripped my pants down and rubbed his cum all over my pussy and fingered it into myself (im on the pill) and licked our cum off my fingers after I came.
Holy fu**. This has happened atleast 10 times since. It’s our game that he HAS to know I’m playing with him too. We’re going to fuck - just having too much fun with this for now.
