Step-Brother Touching Me In The Bathtub Naked Suck Finger Masturbation

First, my Step-brother caught me washing my head in my bathing suit in the filled bathtub and approached me. I was shy and asked him to get out, but he decided to stay and I continued washing my head. I asked him to give me the conditioner and decided to undress, he pestered and touched me, masturbated me, gave me a finger to suck and I continued to wash, finally he enjoyed it and left.
