1.
A fast and furious act of sex in an alley way close to a nighclub or bar. Normally unfulfilled due to coitus interuptus from other couples attempting a knee trembler or a sudden onset of brewers droop or being moved on by the Police.
We had a quick knee trembler but the coppers chased us of before I copped off.
