His wife was upstairs, asleep. Dave thought he had time for a quickie.
He boiled the kettle enough so the water was boiling, but there wasn't enough steam for the kettle to whistle.
Pouring the water into his 'I <3 Spreadsheets' mug, he threw a teabag and a teaspoon of sugar into his cup. His tea was almost perfect. There was one thing missing.
He grabbed some red-cap, skimmed milk from the fridge and started to pour it into his cup. The white liquid trickled from the end of the bottle into the mixture below.
He took the tea upstairs to his bedroom where his wife was waiting, but he was in for a shock when she was awake and saw him with the tea!
"Dave! We talked about this! You need to stop drinking tea. It's become an addiction!"
Dave didn't care what his wife said. He was turned on the by the combination of tea and his half-naked wife.
He poured the tea on his wife and proceeded to make love to her as she was writhing in agony because she was covered in boiling hot tea!
