I came to visit my stepbrother and accidentally saw him jerking off in his room, watching porn from his computer. It really turned me on and I ran to my room, wanted to get my rubber dick, but I forgot it. I saw my breasts in the mirror reflection and began to imagine my brother undressing me and touching my breasts. I've always wanted to try to fuck him, but he has a girlfriend. All these thoughts excited me to the point that my hand went into business. I slowly lower my hand, touch my breasts and move lower to my pussy and start masturbating. I bring myself to orgasm and notice that my brother looks into the crack from the fact that he looks at me and I finished.
