SQTE-149 - Are girls with perfect breasts actually nymphos in bed?

I don't get why they'd gather so many busty actresses just to shoot most of it in backlighting. Are they trying to be artsy? All I see are silhouettes. In Kurata Mao's case, the camera angles are bad and the actor is just doing his own thing. Sakai Ami's blowjob scene is shot in direct light, so that's the only good part. Arai Azusa is okay, I guess. I suppose only people who like backlighting should buy this.
