My brother and I have all sorts of secrets shared together, as it is absolutely normal between siblings: to create a world of our own without parents and other annoying adults. But our secrets are deep and full of meanings, our secrets are not like any ordinary secrets of any ordinary people, our secrets are special as we are special. For example there is a lot of sexual interaction between us, but this would outrage any adult, so that's why we bury our little fun times and whisperings. This time I wanted to tease my brother to do something that might reveal a life and interaction that we kept untold by now. We have to study for an exam, Mother is around the house, doing chores and we are condemned to sit at this table and do our homework. But we got extremely bored and I started to bet that my lil' brother doesn't have the courage to take his penis out and rub it under the table! I even teased him with my big tits, to be sure he gets a healthy boner! "If Mother sees you with your cock out she'll also see me with my boobs on the table, so we're even now!", I said giggling! After I see him getting hard I encourage him to do it, to do it for me, his sister. I want to see him squeezing it hard, to jerk it off violently, harder and faster, faster than that, baby brother! "Let your hand slide up and down on your cock, brother!" I hurry him to touch himself more and more fast until I make him cum all over himself under the table. "Yeah, feel that cum that's gonna explode from your balls!" Well... I lost the bet! But....we did it! We did it one more time, hi, hi
