Im 16 years old and share a room with my brother that is 14years old. I mastubate alot and i usaly did it in the bathroom or in my room when my brother was out but afew weeks agow i found out how exciting it was to wank to a pair of panties and then cum in them. As i DONT want my sister to know (she is 17) i usaly keep 1 pair over afew days and just mastubate mindlessly to them, they get coverd in my sperm and that only make me want to do it again. One day i forgot to lock the door and my brother cauth me wanking to a pair of pink panties. i found it very embarrasing, not only for being cauth but that my brother also commented how small my PENIS was. I got a kinda small PENIS at around 13cm ad he got a 14cm PENIS. I dident want him to tell anyone about that so i asked if i could do anything so he wouldent tell. "let me fuck you" he said and as the fool i was i agreed to this(i had never had sex before so i dident know what to exspect). It hurt like hell(we dident use lube)and it wasent like he took is easy, full speed unetil he came inside of me. I have been turned into his little sexslave cause i dont want anyone to know about the panties or that he fucked me. As soon as he feel abit horny he eather want me to give him a blowjob or hump me. im veally confused and i am asking for the myg0t community to help me.
