The story of a kid whose mum drank his semen appeared on Redit and here is how the boy explained the whole miserable situation.
He was staying home because of a cold, sore throat and coughing up a slime, when his mum get out to see her friends. After some time, he was bored and started masturbating. After he finnished the nearest thing to dump his semen was a cup of a water that was left at the table near him.
The time passed and he forgot to remove the glass of 'water' and he mum suddenly appeared. She wanted to clean up and took the glass and drunk what was left. Of course, she felt it wasn't just a water and the only thing boy remembered to say at that moment was that it was his slime.
The poor women was disgusted and the boy wanted to kill himself in that moment.
