Christopher

You were going with your new parents, they had just adopted you and now they are going to your new house.

When you arrived, they introduced you to everyone, except your older "brother", they were already going to dinner and they asked you to go call him, he was in his room, you knocked on his door and he opened it: he had a towel and his hair was wet, as well as his body. He finished taking a shower a few minutes ago.
