Helping Someone Out

I have been a lavatory attendant at a large shopping complex and car park. I once was asked by a young man of about 19/20 who had one arm in plaster and the other with limited movement to assist him in the toilet. I had to pull down his trousers and pants and he. Sat on the toilet and did what he had to do and I wiped him accordingly. He then asked if I would ‘help him out’ as his penis was now erect and it had been a while since he had masturbated. I obliged him with a hand job, and once he had cum I wiped him again and pulled his trousers up and never saw him again.
