Maybe we have a J-Pop boyband. The boys in the group are 22, 21, 19, 18 and 16. The story would center around the youngest member. They have been together a little more than 4 years. The junior member of the group has just turned 16.
16 has a girlfriend back home, but because of the band working on a new album, or videos, or on tour they are often separated for a month and sometimes longer. The girl is getting rather bitchy as what little time he does have he spends with [one of the band members, or some other boy his own age] him instead of her. He should be with her she insists and teases him about having a bro-mance going on.
16 has done some minor playing around with other boys. The groups management has kept the female fans away from the boys until they turn 16. Even then they supply the women which are often near the ages of their moms and usually not too tantalizing. But boys need sex so the couple of women in the boy's entourage don't have too much downtime. When the band meets in Hawaii to work on a video and record songs for their new album 16 will finally be able to try one of these women if he so chooses.
Among the boys in the band there is some homosexuality going on. Management mostly looks the the other way, but put 16 off limits until he turned the magic age [which he did as this role play begins]. It may be going on between just two of the boys, or all of them. 16 may, or may not know that it is going on. He will be hit on by at least one of the other boys. Whether he chooses to fool around, who knows.
I can play 16, or you can. The band can be white boys if you prefer.
