We did a photo shoot like that a couple weekends ago. It was a 3 night cabin party in the Smokies. Saturday night a professional photographer (and attendee as well as overall awesome guy) took boudoir photos of anyone who wanted to participate. Quite a professional operation, though we all participated to some degree. One of the ladies took over as director, suggesting costumes, positions and overall composition. Ladies helped each other get costumes on. Men helped with props, staging, and lights. The ladies all joined in for a memorable group photo at the end.
There really wasn't much sexual tension built through the process, but it did give us all a chance to interact with each other in a "not-vanilla-but-not-fucking" kind of way. We all did something, even if it was to applaud a good pose, or wolf-whistle for a new outfit. It broke the ice, it made everyone comfortable, and encouraged even the most shy of the ladies to participate. It even worked on me: I'm notoriously photo-resistant, and they got me into a few shots willingly.
