Second hand story

A story I got second hand from another guy.  He knew a guy who at 15 was watched having sex by an older man. The first time it was unexpected.  The second time the older man convinced him to be watched again by saying that he had already watched him have sex and he might as well let the older man watch again. The older man would continue to watch the younger guy have sex until the younger guy graduated high school and enlisted in the army. After he got out in 4 years he went back to letting the older guy watch him have sex. His reasoning was the older guy had watched him have sex since he was 15. This went on for at least another 10 years.
