When you're 18 years old, where do you have to go to be able to fuck in peace? The answer: a service staircase, the ideal place to spice up the excitement! But be careful: wet paint!Pre-occupied by their fucking, the two teenagers haven't noticed that above them, two young painters lay down their brushes to take care of their own rollers for the first coat! A tarpaulin over the stairs, overalls round their ankles ... they fuck on every floor. What a job; a staircase of services rendered !
