Massaging My Sleeping Nephew

My 18-year-old nephew is a really attractive young man. Since his adolescence, I started feeling a little curious about how he was developing and I often tried to sneak a peek at his body while he was showering or changing in his room. It also happened that he had to sleep over some nights or he would pass out on the couch when he came back from school: he was a pretty heavy sleeper and I always tried to get a better look at his body by slowly pulling his blanket off of him, but never got any luck as he used to sleep in baggy clothes all the time. Finally, the chance to see all of him presented itself.
