backyard BBQ

Me & my very pretty wife were invited to a party at my co-workers place. He was recently divorced & was living with his buddy. Two other couples were there. It was a hot sticky evening. We all had shorts & t-shirts on , just in case they suggested we take a dip in their pool. My wife had her little white bikini on under her clothes (my idea). About midnight the other two couples left. I suggested we leave too. My friend talked us into staying for one more drink. They decided to take a dip & removed their shirts & jumped in the pool with their shorts on. . They were in a remote area & it was a dark night I took my shirt off & followed suit. I reminded her that she had a bathing suit on under her shorts, To remove the shorts & come on in. Her bathing suit was very skimpy. Not much more than three tiny patches that barely covered her nipples & pussy I admit, I was excited all evening anticipating this moment.. Without hesitation, she removed her shorts & shirt & joined us in the water. Some light shown from the kitchen window. They got a pretty good look at her. They both realized the bottom was no more than a G-string. Her ass completely bare. The top hardly covered her nipples. As she splashed around occasionally revealing them. After a little while we all got out. The thin cloth of her bikini almost disappeared .because of the wetness. Her nipples, now hard from the cold water stood out. Even her shaved pussy lips were completely viewable. It did not phase or embarrass her one bit as she reached for a towel. My friend offered to dry her off & began doing so. feeling her up as he dried her. They both asked my permission to tell me how beautiful she is. That did embarrass her a little, She was about to put her clothes on. My friend begged her not to & remined like she was. A shot time later as she was about to put her clothes on, she announced "what the hell, you seen everything", removed the bikini, & strutted around their kitchen completely naked to tease them. They both jumped off their chairs & sandwiched her between them, both with obvious erections. She announced, "it's your turn , take it off. They both removed their shorts, both with erections. One looked at me, while holding her hand & asked "ok to take her in the bedroom"? I nodded ok & got a beer from the fridge, They did not appear again for 11/2 hours., me watching TV. . The three of them ran out & jumped in the pool again. Not sure, but I believe they took turns & fucked her again, as I could hear her grunting. I think I disappointed them. They assumed it would be a regular thing. We did return one other time, though. She loves variety. She says doing the same old, same old gets complicated. Just another one of her "adventures".
