Jonathan Keane - "Boy's on Film 8: Spring"

Not going to lie, stole these caps directly from this site - http://eviltwincaps.blogspot.com. While not geared specifically towards underwear you will find it there along with a ton of nude caps. Good site, check it out. Anyway, didn't see this movie/scene but it looks like some BDSM may be going on? This scene goes on (sans white briefs) on eviltwins site if you want to see what else happens.
