Public fucking on the lake

One summer morning I came to the lake to swim.
There were not many people on the lake and I decided to masturbate a little in the car before swimming)
I started massaging my clitoris, and then I inserted my finger into my wet pussy...
But my boyfriend saw me masturbating, took out his dick and started jerking off too!
I couldn't resist the temptation, took his dick in my mouth and started giving him a blowjob)
Then the guy turned me around and started fucking me from behind right in front of the people who were passing by!
He cummed right in my pussy!
Hot sperm started flowing out of my cunt and I wanted to piss! I was embarrassed by the people around me, went behind the car, sat down, spread my legs and started to piss! But then a puddle of sperm came out of me!
