I walk up to my brother who is outside relaxing and looking sexy as can be. I know I shouldn't be thinking like this because I have a boyfriend and I promised myself I wouldn't cheat on him but I can't help myself. To tease my brother, I plop down across from him and purposely have my legs spread so he gets a clear view of my panties. I see that it worked and he is getting hard and it makes me so fucking wet. I tell him that I can't cheat on my boyfriend even though I miss the taste of his cum. I get a brilliant idea. Its not cheating if we masturbate together, right? I know exactly what he likes so I stuff my panties inside myself and pull a little vibrator out of my purse and make myself cum. I then take my wet panties and him to cum on them. He does and I stuff the panties in my mouth so I can taste both of our juices. Mmmm, tastes so good!
