This team-up happened by chance when Summer Sinn was modeling at SCORE for a couple of days. Crystal Gunns was in Florida to perform at the Booby Trap in Pompano Beach, about an hour's drive north of SCORE HQ. CG had dropped in with her roadie to get some magazines and DVDs to sell after her shows. Popping into the studio to say a quick hello to the staff, which she always does, Crystal and Summer were introduced while Summer was being photographed. The girls had never met before. Someone in the studio brought up the idea of a twosome shoot, not a stickee-lickee girl-girl of any kind, just basically a fun-type anatomy assay. Luckily, Crystal had a few free hours in the AM the next day and Summer was game. Our videographer rolled tape during the still shoot to capture the event for boobological history. Some might say the girls have physical similarities; others will say they don't. Whatever the case, both are two big-bust stars with mucho sex appeal. That's a jack fact!
