Underwear tricks, enjoy.
I read on Solo Touch that boys like to spew sperm into girls underwear. So I got the idea of getting back at my older brother, Jack, for playing mean tricks. One day when my brother was showering I went into his room and grabbed a pair of his boxer shorts. I got completely naked and put on his shorts. My vagina was soaking wet now. I rubbed myself until point of no return. I took off the shorts and smelled them, yummy! I returned the shorts. Later saw that he had put them on. He smelled like me with a huge wet stain.
