Beach photo shoot

we were on vacation in Mexico at a nice beachfront resort one afternoon after too many drinks I asked my wife to go for a walk down the beach away from the resort I took my camera hoping to get some pics we walked a bit and it seemed deserted my wife slowly striped as I clicked away we were both getting hot as she posed on all fours showing me her shaved pussy I saw someone close by on the beach my wife freaked and try to cover up but the guy was only a few yards away. he started to apologize for interrupting he seemed nice enough young guy probably mid 20s I convinced my wife to take some more pics as he had already seen everything already she was half drunk and said ok . I took a few more then asked the stranger to take some of the 2 of us he was more then happy to he took a few of her sucking my cock and me playing with her pussy I had him hand me the camera a he was having a hard time getting good shots. I had the idea to have him pose with my wife for a few pics also my wife had her doubts but after looking at the bulge in his swimsuit she said ok but no touching .I had her pose by him that is when the battery died in the camera but I didn't say anything just continued I told her I wanted both of the nude her got big when he dropped his suit and a 10 inch cock popped out I had them pose close together then him behind her cupping her tits I said I wanted some fake action shots so I had her open her mouth and put his cock inside but not touching the side then I had them pose with her on all fours and him behind her. I told him to slide his cock along her ass crack it would look like they were fucking I acted like I was still taking pics I told them to move some so it would look real that is when it happened either my wife went to far forward or he pulled back to far but as I was in front of her she froze for a moment as her eyes flew open then she went nuts and started slamming back into him as his cock had slipped inside .I couldn't look away as they fucked in public on the beach I put the camera down and walked to her and she sucked my cock like a wild women she was cumming every few minutes I told her to get up and straddle him as I got behind her and fucked up the ass she was on fire and we both came soon I shot a load in her ass and he shot one on the outside of her cunt she asked him to come back to our room but he had to catch a plane
