Driver sucked and boyfriend fucked

Darina Ivanov and Clarke Kent got into my cab today, and asked me to lift them to the Uni Bar. I could tell they were new lovers, because they could not keep their hands off of each other. Within a few minutes Darina was grabbing Clarke's cock, and then he started taking out her tits! When she spread her legs, I could see that Darina was not wearing any panties, and the sight of her pussy really turned me on. Since they were so horny, I made them an offer: I'd lend them the cab for 30 minutes if Darina sucked my cock...
