After taking a relaxing bath I catch my step-brother masturbating in front of the mirror in my room and it makes me so excited that I get on my knees and start stroking his cock, sucking it, tasting it from top to bottom and putting it all in my mouth, I can't believe I'm doing this, but it was so hot, I want his cock between my big tits and I give him a titjob, fast, slow, very fast, oh how he loves it and so do I and he cums on my tits and I'm so happy and fulfilled to have made him cum. Oh don't blame me for that.
