This happened my years ago when I was a teenager.
We had a lady cleaning our house once a week. She was a nice single mom in her 40s and not extremely sexy. She came from a conservative background and dressed accordingly – always in a worn out dress that hid her thick ass and heavy tits.
Being that age, I did what every teenage boy does – I would masturbate pretty much the whole day long whenever I could and wherever I could. Keep in mind there were no smartphones or internet – just worn out magazines and mostly imagination.
So that particular day, I decided to skip school and stay at home. I totally forgot about Rita (lets stick to that alias) and when I woke up with a raging hard on – I didn’t think twice, threw the sheet away and went at it full speed ahead fantasizing about some chicks from school with my eyes closed.
