Being watched

my riskiest public sex was when I knew I was being watched, I was going out with a guy called Steve he wasn't very good looking but had a fit body and a big cock and knew how to use it, we were at an air show (he liked them) when I got bored and decided I wanted to suck his cock I told him and he was up for it so we went for a walk and found a quiet place round the back of a big building next to the airport fence, the fence had undergrowth near it and as we came round the corner of the building i briefly saw a couple of guys who were watching the show from outside the airport, they ducked as they saw us I was about to say we cant do it here but the idea of doing it while being watched suddenly became very exciting, when he thought no one could see I dropped to my knees and glancing sideways I could just make out the guys in the bushes who were keeping very still, Steve pulled his cock from his jeans and I took it in my hand and put it in my mouth more excited to know the guys were watching than from the blowjob and making sure they had a good i view started to give him a pornstar blowjob lots of hand and head movement while rubbing my tits with my spare hand, the idea was just to blow him but I was so turned on knowing we were being watched I decided to give them a real show so I took his cock from my mouth and told him I wanted to be fucked he was up for it so I pulled my jeans down and went on all fours making sure the guys in the undergrowth got the best view, Steve got behind me and and after rubbing his cock on my ass crack a couple of times entered me knowing we didn't have long he was hard and fast I moaned just loud enough to be heard by our watchers who I hoped were wanking away in the bushes but I will never know that, Steve said he was going to cum so not wanting to walk around with a wet patch in my jeans I turned round and was about to put his cock in my mouth to swallow when I thought I would give them a bit more and wanked his big cock until he came with a loud groan, we quickly got dressed and went back to the air show and Steve never knew about our uninvited watchers
