The first time he tied me up outside

We were talking about our fantasies one day and he said he like to see.me tied up in a public place available for anyone to play with
I agreed as long as he stayed with me,so one day we went for a drive in the country and found a quiet spot

I was wearing a short skirt and blouse nothing else ,in the park were some picnic tables so I bent over and he tied my legs to the table and feeling horny lifted my shirt and took his cock out and we had a great open air fuck
Then he tied my hands up and say next to me and we waited to see if anyone would come by ,about ten minutes later a guy walking his dog walked by and stopped seeing me tied up .He said is she ok to hubby and hubby said I don't know I found her like this with a note pinned to her skirt saying please help yourself,she loves being abused but don't untie her or listen to her
He said what's her name and hubby said Helen ,lying , so he looked at me saying she looks lovely and I said fucking untie me please
He lifted my skirt and said no knickers ,hubby said the sign said help yourself ,I heard his zip and then his fingers playing with my ass and in my cunt ,next I felt his cock enter me and said please don't you bastard untie me please ,hubby just say there while he fucked me ,I couldn't help my hope moving as he shot his load in me and over my ass ,He then sat down and started playing with my tits ,fucking leave me alone I begged ,he asked hubby if he had fucked me ,no not yet but he fancied my ass ,go on then said the stranger as he squeezed my tits ,so hubby ,playing along slipped his cock up my ass ,I started screaming stop you bastards but hubby laughed and came up my ass . He pulled his cock out and said fuck her ass is tight do you want to try it
So then he had me up my ass again ,it was so fucking lovely but I pretended not to like it screaming **** but knowing no one could hear he just kept on fucking my ass ,my cunt was soaking wet and I was cumming ,I couldn't stop ,fuck me , fuck me I shouted and he did so fucking hard it hurt and then I felt his load erupt up my ass
He then left saying to hubby she loves it fuck her again ,hubby said I might
We waited for a while but no one else came by so hubby untied me and I sucked him off before we drove home , I was naked of course and playing with myself on the way ,as hubby told me about the stranger
Would have liked a few more cocks but maybe next time
It was lovely being abused by a stranger with hubby watching , it made me so fucking horny I want to do it again
