When Silvia opened the door, she was wearing a button down shirt, and nothing else, The shirt was unbuttoned enough to expose her cleavage and enough...of her breasts to get me hard. She was built very well, nice body, with at least 38C, maybe a D cup tits. She told me that at times she had to wear D cup bras, but most of the time she squeezed into a C.Ok, this was my first FMF 3some, so I was way turned on and excited. I could not believe Silvia was going to do this for me. She told me that. Alonzo called for a drop of miscellaneous supplies, especially ammunition for the M-14s. He realized that there had been a mistake when he failed to request tracers be included when we started out. He also ordered two more magazines for our rifles and a combat radio for each of us. Other than that, it was a standard drop of three days worth of consumables.The supply drop was scheduled for noon tomorrow, and he gave the GPS coordinates that he wanted to use. We reached the drop zone well before. We then talked about thongs and she said she was wearing one. I joked with her saying I'd love to see it. Her next move shocked me as she undid the left shoulder strap buckle, turned around and lowered her overalls to partially expose her perfect ass in this black thong. My heart was again pounding with excitement.I couldn't believe my eyes as she stood there just sticking her dark tanned butt at me. I had to act fast and asked her to drop the overalls lower so I could see her whole ass. She. And all I could saw was awesome. At this point she said that she felt I was enjoying them so she doubled the amount to Thirty Six at full force.when I tried to stand I nearly fell over. Julia caught me just in time. But as I caught her I had pulled her corset down revealing her massive boobs.She just laughed telling me I was a naughty slut. Then Julia helped me through another door which was really bright and white. She helped me onto a couch and pumped it higher. I asked her if I was now.
