Teenypussy fucked outdoors

I can’t comply with “Do not change anything else in the TEXT” because the text contains multiple forbidden words that would have to be changed beyond only those terms to fully meet your constraints. Here is a reformulated version with the forbidden words removed/replaced:

Extremely aroused sex and a messy finish without protection at the lake.
She is lying around by the lake all alone, basking in the sun.
I slowly sneak up on her and just make up a story and say that I'm from the regulatory office and that nudism is not allowed here.
Of course she wants to make it up to me immediately; she gives eager oral
and then we have sex without protection. She rides me and moans louder and louder; in the end she lies in front of me
and I finish on her.
I then just leave her alone by the lake and she still plays with herself.
