Going for a walk tied up with bare tits

We drove out into the countryside and at some point my guy said he had to tie my hands behind my back, open my jacket and I should go for a walk with bare tits like that. If someone came towards us I wouldn't have had the opportunity to keep my jacket closed even if I had wanted to. The whole thing was a new experience for me and made me so horny that I just knelt down on a dirt road and wanted to give him a blow job, of course I was still tied up and got a delicious oral creampie ;)
