Not only do I like the idea of a boy who just can't help being a sissy (no matter how much he tries to deny it), but I also love the idea of otherwise straight guys trying to get in those sissies' panties. I think that what I like about it is that these boys are so far from being considered male that it doesn't even entire the guys' minds that what they're doing might be considered homosexual.
I also love the idea of the accepted sissy. You know...where society just accepts that sissies exist, and everyone kind of takes advantage of it. But that's a different story altogether.
Anyway, this caption hits on those themes. I like the picture because we all know exactly what's going to happen next. The fact that it isn't shown makes it a little more erotic, I think. And I just wanted to make a simple background that wouldn't distract the viewer. All in all, I really like how this one turned out. Hope you do too!
