Attention quick splash - alarm! Can he make it in 3 minutes?

I was totally stressed and had to rush to catch the train as it came round the corner to honour my debt. Unfortunately, this didn't fit in with my schedule at all, I had to catch this train urgently if I didn't want to wait another hour for the next one. So I gave him just under three minutes, which was how long I had to honour my debt and release the pressure. The longer he took, the more nervous I became. But he kept ramming his cock into my pussy, over and over again and calmly. The seconds passed and the fear of missing my turn grew ever greater while he calmly enjoyed what he was doing. What will I do when the time is up and he hasn't finished yet? Will he at least give me a lift then or will I owe him "something" for it again, even though it's his fault that it could have come this far in the first place? Now I finally want him to come quickly and of course things turn out differently...
