While reading in bed, I realize I need to pee.... really bad. I can't hold it any longer so I rush to the bathroom, but someone is already in there. I wiggle around trying to hold my pee, but they're taking too long. I piss myself, soaking my panties and making a puddle on the floor outside the bathroom. Suddenly the family comes up to me and starts sniffing my panties. I scold him, but realize he must really like the smell of my pussy. I get a naughty idea, and bring him into my room. I pull down my pee soaked panties and let him knot me, all his cum filling me up to the brim. I realize I won't be able to make it back to the bathroom without leaking all his cum and giving myself away... so I quickly take my soaked white panties off and stuff them up inside me to plug the cum. Once in the safety of the bathroom I pull them out and let all his cum and a little more pee gush out of me.
